This paper investigated the peculiarity of a sentimental phenomenon called attachment to personal belongings. The aim is to examine the correlation between people and the belongings composing their living environment, in order to reveal what is important and meaningful for both their liver and their living environments. The Study looks at the relationship between experiences with belongings particularly close to the owner and feelings of attachment for them. A survey of experiences and sentiments about belongings with attachment was executed and factor analysis was used to bring out the components of attachment. The results verified the following: 1) in each group of samples with a similar tendency of factor scores, the experiences with belongings have something in common. 2) From the tendency of factor scores, there is a difference in attachment between things of the same kind. 3) The owners recognize the empirical products of relation to belongings. These results show the formation of an attachment is connected with various experiences with the belongings.

Objective: To clarify the educational effect of a lecture on differential imaging features comparing ameloblastomas and keratocystic odontogenic tumors of the mandibles presented to dental students.Methods: Panoramic and CT images of 10 ameloblastomas and 10 keratocystic odontogenic tumors were randomly presented 114 dental students. Test scores, correct answer ratios, identification index, and understanding of the imaging features contributing to a correct diagnosis were serially evaluated before and after the lecture on the differential imaging features comparing the two types of tumors.Results: The mean and standard deviation of the scoring ratios of dental students diagnosing these lesions on panoramic and CT images were 48.8 ± 10.8% and 52.5 ± 12.9%, respectively. After the lecture on the differential imaging features comparing the two tumors, the scoring ratios improved significantly. After the lecture, both the numbers of patients whose images were correctly diagnosed and the identification indices increased. The lecture also increased the number of imaging features recognized as contributing to the correct diagnosis.Conclusion: A lecture on the differential imaging features comparing ameloblastomas and keratocystic odontogenic tumors of the mandibles contributed to the improvement of imaging diagnosis skills among dental students.

本研究は,市販12%金銀パラジウム合金のうち,銅20%を含む合金(GCW)および銅10%を含む合金(TKG)を用いて,歯科精密鋳造法に準じた方法で引張・硬さ・変色試験片および内壁に1/10テーパをもつ変形測定用試験片を作製し,歯冠修復物や鉤製作時の熱処理効果を検討した.試験片を700,750,800,850,900℃で10分加熱,溶体化処理したのち水中に投じて軟化熱処理を加えた.得られた測定値を溶体化処理温度について解析した結果,TypeIV鋳造用金合金に匹敵する強度を持たせるために最適の溶体化処理温度はGCW合金で700∼750℃,TKG合金で800∼850℃と推定され,12%金銀パラジウム合金では銅量の多い合金ほどより低温で溶体化処理したのち硬化熱処理を加えることが必要であることを明らかにしたものである.
