U.S. Intelligence and the origins of the Vietnam War, 1962 - 1965

Analysing documents produced by the CIA, the State Department and the Pentagon, the thesis examines the role of intelligence assessment in U.S. Vietnam policy during the period between December 1961 and February 1965. It investigates intelligence on the counterinsurgency in South Vietnam, on the intentions and capabilities of North Vietnam, and on the probable consequences of policy options. The first half of the thesis examines the Vietnam intelligence during the Kennedy administration, following the rise of optimism in 1962 and the intelligence dispute in 1963. The second half of the study explores intelligence developments from the fall of the Diem regime in November 1963 to President Johnson’s decision to take military action against North Vietnam in February 1965. The study suggests that intelligence deficiencies played a significant role in both the failure of counterinsurgency in the first half of the 1960s and in the decision for direct military intervention in 1965. The thesis also demonstrates that, rather than simply being a result of technical weaknesses, the lack of robust intelligence reflected wider problems of Vietnam policy, including political pressures, ideological contexts and the absence of strategic consensus

多形腺腫における細胞分化因子としてのNotchの可能性

The expression of Notch in 30 cases of pleomorphic adenoma was examined by immunohistochemistry.Comparing the results of our study with previous literatures, from the partial CK7 expression and substantial Notch expression in ductal epithelial cells as well as the Notch expression in solid tumor nests, it can be inferred that Notch is involved in cell differentiation. CK13 expression was observed in cells undergoing squamous metaplasia and Notch expression was seen in the nucleus of basal and squamous cells. The intense Notch expression in basal cells and weak expression in squamous cells suggests that Notch is involved in the differentiation from basal to squamous cell. Moreover, the loss of nuclear expression on the inner layer would signify that differentiation is about to end or has been terminated. Notch was expressed in the cytoplasm of cartilage cells and in the cell membrane of mucous cells but not in the nucleus indicating that differentiation has been concluded. Notch involvement is suspected in cell differentiation in areas showing ductal structures and squamous metaplasia. In summary, Notch is involved in cell differentiation of ductal cells in PA. Nuclear expression was shown in tumor cells in solid nests and surrounding structures. Moreover, Notch is expressed by basal cells undergoing squamous metaplasia suggesting the participation of Notch in cell differentiation in PA.2015博士（歯学）松本歯科大

A case of impacted supernumerary teeth occurring in the bilateral mandibular premolar area

In this study, a 1₇–year–old patient, who had regularly visited us from childhood, complained of discomfort in the andibular molar area, and impacted supernumerary teeth was confirmed by radiography. Its position was closely investigated using 3–dimensional CT, excision was performed, and a favorable course has been achieved. Thus, the importance of screening using panoramic radiography was reconfirmed

地域活動への住民参加を促すための保健師の支援方法

A地区の地域活動への住民の参加状況と参加条件を明らかにするため、4団体108名を対象に質問紙調査を行った。地域活動への参加条件として重要なのは、健康であること、家族の理解と協力があること、身近な人と一緒に参加できること、活動場所が自宅に近いこと、活動する時間的余裕があること等が明らかとなった。地域活動支援のあり方としては、個人や家族の健康を保持・増進し、地域の人々のつながりを強め、時間・場所・移動手段を工夫し住民が集いやすくすることにより、参加条件を満たすことが有効と考えられた。保健師は、個人や集団が地域活動を活発にするための工夫や連携を図り、個人・集団の力を引き出せるような支援をしていくことが重要であると考えられた
