埋蔵文化財発掘調査機関における労働安全衛生管理の実態と発掘作業の労働負担を明らかに、その対策を検討することを目的に、本研究を行った。都道府県教育委員会関連の発掘調査機関においては、「救急蘇生の講習会を開催している」および「定期健康診断を実施している」機関は25%以下であった。労働災害発生件数に関連する要因として、「独自に雇用している発掘作業員数が多いこと」および「安全衛生に関する規定がないこと」が抽出された。夏期に発掘現場の作業環境測定を行った結果、WBGT(湿球黒球温度指標)は中等度の労働強度における許容基準を超えている時間帯があった。鼓膜温は、発掘作業中上昇し、休憩によって下降するパターンを示した。体温の最大値は、午後の第1回目の休憩前に記録された。冬期に作業者の血圧等を経時的に測定した結果、収縮期血圧の最大値は発掘作業開始時点に記録された。これは主として発掘現場における寒冷曝露の結果と考えられる。ダブルプロダクトは、発掘作業中上昇し、休憩時に低下するパターンを示した。冬期における作業者に自覚症状を調査した結果、発掘作業中に防寒靴を使用する者の自覚症状の有症率は、使用しない者よりいくつかの項目について有意に低率であった。しかし、「足の冷え」については両者の間で有意差がなかった。これらの結果から、冬期の発掘作業を快適に行うための方策のひとつとして防寒靴の使用が勧められる。寒冷紗の効果をみるため模擬発掘現場で炎天下と寒冷紗のWBGTを測定した結果、寒冷紗下では乾球温度、湿球温度、黒球温度が低く、その結果、寒冷紗下のWBGTは炎天下より低くなっていた。したがって、夏期の発掘現場における寒冷紗の使用は、夏期の埋蔵文化財発掘作業を快適に行うための方策のひとつとして効果があることがわかった。しかし、寒冷紗下の風通しを悪くすると効果が低下することも明らかになった。

In winter, many people have trouble with chilliness in their arms and legs. Many women are especially sensitive to cold, and for them the chilliness of the hands and the feet is difficult to ease even after entering a warm room, or taking a bath. They even feel pain owing to coldness of their limbs in daily life. This symptom has been called “hiesho” in Japanese.The problem of this chilliness is difficult to study because this symptom, in general, can be cured when spring comes. Coldness of the limbs has been considered to be one of the symptoms of the climacteric disturbance among middle-aged females.Recently, however, it was reported that many young females also feel pain owing to coldness of the hands and legs in their daily life during winter.This study investigates the problems of chilliness in the limbs of young females in their daily life. By means of a questionnaire, 642 female college students aged from 18 to 20 years answered questions concerning: (1) physical characteristics, (2) physical conditions in their daily life, (3) physical conditions in winter, and (4) physical conditions in summer. The replies to the questionnaires were tested using the χ2 test.The major results were as follows:1. Half of the subjects were sensitive to cold, and had difficulty sleeping owing to chilliness of their limbs in winter even in a warm environment.For the following results the subjects who were sensitive to cold had significant differences (p<0.05) compared to non-sensitive subjects to cold.2. Those subjects who were aware of chilliness in their limbs had high prevalence rates for irregularities in circadian body rhythm, as well as some symptoms such as white fingers phenomenon, numbness of their limbs, and stiffness in their hands.3. The subjects who were aware of chilliness in their limbs were very sensitive to cold in winter, and had female family members who had the same troubles with chilliness in the arms and the legs, too.4. The subjects who were aware of chilliness in their limbs were sensitive to cold even in summer, and had difficulty sleeping owing to chilliness of the limbs.

The maxium biting force in 82 male athletes and 12 male subjects without any particular athletic activity (nonathletes) were measured in order to evaluate the relationship between biting force and physical fitness in athletes.The results obtained were as follows.1. The maximum biting force in athletes (50.8±17.4kg) was significantly (p<0.01) higher than that in the nonathletes (28.1±9.1kg). The maximum biting forces in the men who belonged to the rugby or judo clubs were predominantly higher than in other subjects.2. In men who masticated on the left side of the mouth, the habitual (i. e., left) biting force was significantly higher than the nonhabitual (i. e., right) biting force.In men who masticated on the right side of the mouth, the habitual (i. e., right) biting force was also higher than the nonhabitual (i. e., left) biting force, but was not significantly so.3. There was a significant positive correlation between the biting force and grip strength and back strength in athletes. In athletes, there was a significant correlation between biting force and the numbers of chin-ups, the numbers for the side-step tests and the time for 50m running.

To clarify the relationship between the occurrence of the attacks of Raynaud's phenomenon and weather, maximum, minimum and mean air temperatures in winter were surveyed on the days in which the attacks of Raynaud's phenomenon occurred in 4 female students with Raynaud's phenomenon in the fingers. The results obtained were as follows:1) In general, the percentages of the days when the attacks of Raynaud's phenomenon occurred was the highest from the end of November to December, compared to the January and February results.2) Minimum and mean air temperatures on the days excluding holidays when the attacks of Raynaud's phenomenon occurred were significantly lower than those on the days when the attacks did not occur for the subject who went to school from her own home; this result was not noticeble for the others who lived at the dormitory. In all subjects there were no differences in the maximum air temperatures between the days when the attacks of Raynaud's phenomenon occurred and the days when the attack did not occur.

某公立病院看護婦の精神健康状態とストレス対処行動の問題を検討するために230名の看護婦を対象に自記式質問紙調査をおこなった. GHQ 60及びSSCQによる評価ではストレッサー及びストレス評価尺度での高得点者が多くいることがわかった. GHQでは卆後1-2年の看護婦, 婦長, 手術室及び外来勤務の看護婦の精神健康度が低い傾向を示した. SSCQでの高得点者は卆後5年未満と当院で仕事の中心的な存在となっている卆後10年以上の者に多かった. 本調査で特徴的なことはGHQ調査で精神健康度が高い者のなかにもストレス対処行動等において高得点者, つまりストレス予備群を発見できたことである. 以上より, 職場の健康管理において, 職場環境及び労働条件, 勤務配置, 卆後教育等の配慮が必要であると共に看護婦自身が自らの健康状態やストレスを自覚し, 主体的な健康行動をとることが重要であると考えられた.

The researches of masking made it clear that there is a bandpass like a filter in the auditory system. This is called the auditory filter and its central frequency is thought to be the frequency of an acoustic signal. If there exist this kind of filter, the authors expected that the noise image which is perceived when pure tone and noise simultaneously presented is different from the one which is perceived when noise is presented independently. The authors chose an interrupted pure tone as an acoustic signal and continuous white noise as noise, and experimented to investigate the pure tone effect on perception of white noise. As a result, two stimulus tones induced three sound images, which are sound images of continuous noise, a pure tone and pulsed noise. The sound image which listeners did not expect to hear was the pulsed noise image. This phenomenon was thought to be an auditory induction; the inducer is the sound image of the white noise presented with the silent part of pure tone of interrupted pure tone and the inducee is that of the white noise presented with pure tone part of interrupted pure tone. This pulse phenomenon suggests that pure tone change the loudness of white noise. This finding is interesting for researches of auditory mechanism and for the field of hygienics with protecting the auditory system and improving hearing under the noisy environment.

A study was carried out to examine the effects of ingestion of “BON-NARINE” (BN) on mice immune functions. Mice aged 12 weeks were divided into 4 groups. The first group was given BN at 30mg/kg (BN-30 group), the second group was given BN at 90mg/kg (BN-90 group), the third group was given zymosan at 50mg/kg (Zy group) and the fourth group was a control receiving no treatment. The mice of groups BN-30 and BN-90 were given BN p. o. at doses of 30mg/kg and 90mg/kg per day for 20 consecutive days, respectively. The mice of group Zy were given zymosan i. p. at a dose of 50mg/kg per day for 2 consecutive days.The results obtained were as follows:1) Potentiation of phagocytic function of the reticuloendothelial system, examined by the carbon clearance method, was seen in the BN-30, BN-90 and Zy groups.2) The glucose consumption of peritoneal macrophages (Mφ) increased significantly in the BN-30 and Zy groups, but not in the BN-90 group.3) Superoxide anion (O2-) production of peritoneal Mφ significantly increased in the BN-30 and Zy groups compared with the control group, but an increasing tendency was observed in the BN-90 group.4) The acid phosphatase (APH), β-glucuronidase (GLU) and lactate dehydrogenase (LDH) activities of peritoneal Mφ increased significantly in the BN-30, BN-90 and Zy groups.5) The proliferation of splenocytes induced by Con A in the BN-30, BN-90 and Zy groups significantly increased compared with the control group.These results demonstrated that the ingestion of “BON-NARINE” promotes phagocytic activity in the reticuloendothelial system in mice and has a stimulatory effect on Mφ because of increases in glucose consumption, O2- prodction, APH, GLU and LDH activities in the peritoneal Mφ of mice. BN also intensified the T-cell function represented by Con A-induced splenocyte proliferation.
