生育段階の異なるシュートに対する温度条件がシュッコンカスミソウ'アルタイル'の形態異常花序発生に及ぼす影響を検討した.シュート長20 cmから2週間15°Cに加温することで,8週間15°Cに加温した場合と同様に,形態異常花序発生が軽減された.2週間加温した個体の切り花長と切り花重は,8週間加温した個体よりも大きくなった.形態異常花序が発生するシュート長と頂芽における花芽分化段階との関係を調べたところ,頂芽のステージが栄養成長からがく片形成期に当たるシュート長が約1~20 cmから15日間の15°C加温で最も形態異常花序が抑制できた.形態異常花序に及ぼす低温の影響を明確にするため,異なる生育段階に対する低温遭遇(7°C)が形態異常花序発生に及ぼす影響を調査した.異なる生育段階に高温(15°C)に遭遇させた実験と同様に,頂芽のステージが栄養成長からがく片形成期までの低温遭遇が形態異常花序発生に大きく関与していた.以上のことから,摘心直後からがく片形成期の期間,株を低温に遭遇させないように温度管理することで,形態異常花序の発生を抑制でき,切り花形質も改善できると考えられた.

As occurrence of abnormal inflorescence in Gypsophila paniculata 'Altair' is caused by environmental conditions, effects of day length, supplemental lighting strength, shading period and minimum night temperature on occurrence of abnormal inflorescence were investigated. Abnormal inflorescence was classified into four types : normal, pattern 1 (Short-flower stalk), pattern 2 (Coalescent two-flower stalk) and pattern 3 (Looping and irregular-flower stalk). Neither of 12h, 16h, 20h or 24h day length by fluorescent lamp, nor 24h by incandescent lamp affected occurrence of abnormal inflorescence. Effects of four levels of light intensity (fluorescent lamp : PPFD 1μmol・m−2・s−1, incandescent lamp : PPFD 3μmol・m−2・s−1, metal halide lamp : PPFD 14μmol・m−2・s−1 and high-pressure sodium lamp : PPFD 48μmol・m−2・s−1) were examined in 16h photoperiod. Occurrence of abnormal inflorescence was not affected by different light intensities, neither was it affected by shading period. Occurrence of abnormal inflorescence at 15°C was however significantly reduced compared to that at 8°C. In particular, patterns 2 and 3 at 15°C were significantly reduced compared to those at 8°C. There was a strong negative correlation between average night temperature from starting the treatment to flower budding (7.1°C, 9.0°C, 9.2°C, 11.6°C and 16.4°C) and incidence of pattern 3 (13.1%, 8.7%, 7.1%, 1.1% and 0.7%). Therefore, as average night temperature increased, occurrence of abnormal inflorescence decreased. The results show that low night temperature may be the main factor inducing occurrence of abnormal inflorescence.シュッコンカスミソウ'アルタイル'の形態異常花序の発生には環境要因が関与していると考えられたので,日長,補光強度,遮光時期および最低夜温が形態異常花序発生に及ぼす影響を調査した.形態異常程度は4種類のパターン (0:正常,1:茎が短いもの,2:2本の茎が癒着,3:ひどく湾曲し変形したもの) に分類し,その影響を受けた小花の割合を求めた.蛍光灯による日長処理(12時間,16時間,20時間,24時間)や白熱灯による日長処理(自然日長,24時間)は形態異常花序発生率に影響を及ぼさなかった.蛍光灯(PPFD 1μmol・m-2・s-1),白熱灯(PPFD 3μmol・m-2・s-1),メタルハライドランプ(PPFD 14μmol・m-2・s-1),高圧ナトリウムランプ(PPFD 48μmol・m-2・s-1)を用いて16時間の補光を行った.異なる光源による光強度でも形態異常発生率に一定の傾向は認められなかった.遮光時期を変えても形態異常発生率に一定の傾向は認められなかった. 最低夜温を15℃に上げると8℃区と比較して15℃区の形態異常発生は大きく減少した.特にパターン2と3の発生率は大幅に低下した.各実験の処理開始から発蕾までの平均夜温(7.1℃,9.0℃,9.2℃,11.6℃,16.4℃)と,パターン3の形態異常発生率(13.1%,8.7%,7.1%,1.1%,0.7%)との間に高い負の相関(R2=0.849)が認められ,処理開始から発蕾までの平均夜温が高いほど形態異常発生率は低下した.以上のことから,形態異常花序発生には夜間の温度が大きく関与しているのではないかと推察された.

Intravenous sedation under the supervision of dental anesthesiologists is an increasingly common procedure in private dental clinics performed to ensure the safety and comfort of patients undergoing oral implant surgery. A questionnaire survey of patients following dental implant surgery was conducted to assess the level of recognition/understanding of intravenous sedation,presence or absence of various types of uncomfortable events during the perioperative period, and requests/expectations of patients regarding this type of sedation. A questionnaire was administered to a total of 55 patients who underwent intravenous sedation in a private dental clinic during the period between November 2004 and February 2006. Only 32.7% of patients were familiar with the term “intravenous sedation”. Since a total of 90.9% of patients had no or very little memory of events during surgery, the amnestic effects of sedative agents used were considered sufficient. Only a small number of patients reported uncomfortable perioperative events such as maintenance of a posture for a long period of time and coughing due to irrigation. Almost all patients indicated that they were comfortable during the operation, though 7.3% were bothered by the absence of memory during surgery. In order to ensure that patients can fully benefit from the amnestic effects of intravenous sedation, cooperation among the dentist, patient, and dental anesthesiologist during surgery, as well as preoperative management, is necessary.

The purpose of this paper is to make clear the relation between "Tacit Knowledge", "Tact" and "Endocept". We sometimes can't express these human potentials clearly, but they exist certainly. What is Non-verbal Knowledge, in other wards "Tacit Knowledge", which is called by Michael Polanyi (1891-1976 Republic of Hungary)? In this thesis, I'll try to compare "Tacit Knowledge" with "Tact" by Kumagusu Minakata (1867-1941 Japan) and "Endocept" by Kazuko Tsurumi (1918-2006 Japan). And I'll try to find a clue of overcoming the modern science and build a creative knowledge. The construction of this paper is as follows: 1. An explanation and a study of "Tacit Knowledge". 2. Looking into "Mysteries of Li" and "Tact" through a few examples of Minakata's Discovery of algae, in other words "Yariate". About an indwelling and an interiorization which are the most important elements of carrying out "Tacit Knowledge". 3. A study about a relation of "Endocept" and creativity.

Background:The incidence of late coronary artery abnormalities after arterial switch operation (ASO) for d-loop transposition of the great arteries may be underestimated.Methods and Results:We retrospectively reviewed coronary artery morphology in 40 of 97 patients who survived the first year after ASO. Seven asymptomatic patients developed significant late coronary artery abnormalities. One patient died suddenly at home with severe left coronary artery (LCA) ostial stenosis at age 3.8 years. The second patient collapsed during exercise at age 9.6 years due to ventricular fibrillation and severe LCA ostial stenosis despite prior negative exercise stress test (EST) and myocardial perfusion imaging (MPI). The third patient was found to have moderate ostial stenosis of the LCA with negative EST and MPI. The fourth patient with exercise-induced ST-T depression and myocardial perfusion defect was shown to have complete LCA occlusion with collateral vessel formation. Three other patients had complete proximal obliteration of either of the coronary arteries with collateral supply. An additional 4 asymptomatic patients had trivial-mild narrowing of the LCA on routine selective coronary angiogram.Conclusions:Incidence of late coronary stenosis or occlusion was not infrequent after ASO (11.3%) and presented usually without preceding symptoms and often after negative non-invasive screening. We advocate routine coronary imaging in all patients after ASO before they participate in competitive sports. (Circ J 2015; 79: 2372–2379)
