The corps of engineer battalion is in the maintenance management service for about 30 battalions subordinated to the infantry division, but the maintenance management manpower is a small number because the criterion of the maintenance management manpower is in accordance with the battle organization. So, this study suggests the reasonable maintenance management manpower estimating model according to the area, the quantity and so on of army installation. In this case study, we investigate the present states and the actual conditions for the 3 infantry divisions and 3 corps of engineer battalions, and find out improvement method based on the interview with the persons concerned.

제1소구치 발치를 동반한 설측교정치료시 lingual K-loop archwire로 전치부 후방견인을 시행한 경우 전치부 및 구치부에서 치조골에 발생하는 초기응력을 알아보기 위하여, K-loop의 의 vertical lg 길이는 15mm로 하고 편측당 350gm의 힘으로 활성화시킨 후 상악궁 광탄성 모형의 응력동결을 시행하고 각 치아별로 절단하여 3차원 광탄성법으로 분석한 바 다음과 같은 결론을 얻었다. 1. 중절치의 근심면은 치관측일수록 더 큰 인장응력을 보였으며 원심면은 치관측일수록 더 큰 압축응력을 보였다. 순면에서는 치관측일수록 더 큰 인장응력을 보였으며 설면에서는 치근측일수록 더 큰 압축응력을 보였다. 치근첨에서는 압축응력이 나타났다. 2. 측절치의 근심면에서는 치관측만 인장응력이 관찰되었고 원심면에서는 고른 압축응력을 보였다. 순면에서는 치관측일수록 더 큰 인장응력이 관찰되었고 설면에서는 치관측에서는 인장응력을, 치근측에서는 압축응력을 보였다. 치근첨에서는 압축응력이 관찰되었다. 3. 견치의 근심면은 치관측에서는 인장응력을, 치근측에서는 압축응력을 보였고 원심면은 인장응력을 보였다. 순면과 설면은 치관측일수록 큰 인장응력을 보였다. 순면보다 설면에서 더 큰 인장응력을 보였다. 치근첨에서는 압축응력이 관찰되었다. 4. 제2소구치는 근심면은 인장응력을 보이며 원심면은 치관측에서는 압축응력을, 치근측에서는 인장응력을 보였다. 협면은 치관측에서 압축응력을 보였으며, 설면은 치관측일수록 더 큰인장응력이 관찰되었다. 치근첨에서는 인장응력을 보였다. 5. 제 1대구치는 근원심면 모두에서 치관측일수록 더 큰 인장응력을 보였다. 협면에서는 응력이 나타나지는 않았고 설면은 치관측일수록 더 큰 인장응력이 관찰되었다. 협측치근들의 치근첨에서는 압축응력을, 구개측치근의 치근첨에서는 무응력을 보였다. 6. 제2대구치는 모든 치근의 치근첨에서 압축응력이 관찰되었다. 근심면은 치관측일수록 더 큰 압축응력을, 원심면은 치관측일수록 더 큰 인장응력을 보였다. 협면은 치관측일수록 더 큰 인장응력을 설면은 치관측일수록 더 큰 압축응력을 나타내었다. 따라서 전치부 후방견인시 transverse bowing effect는 뚜렷이 나타났으나, vertical bowing effect는 나타나지 않고 오히려 전치부가 함입되려는 응력이 발생하였다. This study was designed to investigate the stress distribution of alveolar bone in case of en masse retraction with lingual K-loop archwire using the 3-dimensional photoelastic stress analysis followed by stress freezing process. Lingual K-loop archwire which had loop in 15mm height was used and activated by retraction force of 350gm per each side. The results were as follows : 1. Central incisor : As the closer side to crown, the larger tensile stress was distributed at both mesial and labial surfaces and the larger compressive stress was distributed at distal surface. As the closer side to root apex, the larger compressive stress was distributed at lingual surface. The compressive stress was distributed at root apex. 2. Lateral incisor : The tensile stress was distributed at the coronal side of mesial surface. The compressive stress was distributed at distal surface. As the closer side to crown, the larger tensile stress was distributed at labial surface. The tensile stress was distributed at coronal side and the compressive stress was distributed at apical side of lingual surface. The compressive stress was distributed at root apex. 3. Canine : The tensile stress was distributed at coronal side and the compressive stress was distributed at apical side of musial surface. the tensile stress was distributed at distal surface. As the closer side to drown, the larger tensile stress was distributed at both musial and distal surfaces. The compressive stress was distributed at root apex. 4. Second premolar : The tensile stress was distributed at mesial surface. The compressive stress was distributed at coronal side and the tensile stress was distributed at apical side of distal surface. the compressive stress was distributed at coronal side of buccal surface. As the closer side to crown, the larger tensile stress was distributed at lingual surface. The compressive stress was distributed at root apex. 5. First molar : As the closer side to crown, the larger tensile stress was distributed at both mesial and distal surfaces. No stress was distributed at buccal surface. As the closer side to crown, the larger tensile stress was distributed at both lingual surfaces. The compressive stress was distributed at buccal root apexes. 6. Second molar : The compressive stress was distributed at all root apexes. As the closer side to crown, the larger compressive stress was distributed at both mesial and lingual surfaces, and the larger tensile stress at both distal and buccal surfaces. Transverse bowing effect was observed in en-masse retraction with lingual K-loop archwire, however vertical bowing effect was not. Rather, reverse vertical bowing effect was developed.

Intravesical chemotherapy and immunotherapy will commonly eradicate residual papillary transitional cell carcinoma or carcinoma in situ(CIS) and clearly reduce the short-term incidence and rate of tumor recurrence. So I reviewed the effects and complications of different therapeutic agents(thiotepa, mitomycin-C, epirubicin, adriamycin, bacillus Cal mette-Cue'rin(BCG)) in superficial bladder cancer confirmed with histopathology, with the literatures. Bladder cancer were recurred more commonly in multiple tumors(50.6-56.3%), high grade tumors(52.6%) rather than in single(30.9%) and low grade(31.6%). And recurrence rates according to therapeutic agents were 83.3% in mitomycin-C, 71.4% in thiotepa, 50.0% in epirubicin, 46.6% in adriamycin and 32.6% in BCG. But incidence of complications were highest in BCG(50.5%). So sufficient preventive manuevers should be needed before intravesical theraphy, especially in BCG immunotherapy.

So far, the corps of engineer battalion is in charge of facility management servics for about 30 battalions subordinated to the infantry division. He operates an irregular organization for construction of new facilities and maintenance of the existing facilities. In 1990, the Ministry of National Defense established a plan for modernizing and improving military facilities. According to the plan, military facilities have been reinforces and increased. However, the facility management manpower has not been increased, although they have retained up-to-data facilities, equipments necessary manpower. Despite new requirements on manpower, even the criteria to estimate facility management manpower in the Army does not exist. Therefore, this study p개poses a reasonable manpower estimating model for the military facility management using the macroscopic and microscopic indices.

N/A The cushion is one of the various factors that is related to inconvenience in using of the chair. This study measured the Body Pressure Distribution(BPD) to compare convenience between new and old air cushion chair and a response for the test. The body pressures of 21 male subjects were measured under the same posture to minimize the influence of variables. The Flexible Body Pressure Mat System was used to measure body pressure of subjects. The result showed that the distribution pattern of body pressure for new product is symmetrically centering around the ischial tuberosities and the highest body pressure was less than old product.

The goal of this paper is to propose a method of user interface display using 1.0㎜ × 0.5㎜ size Light Emitting Diode on mobile phone. We have developed the 1005 size LED and new package of I²c control Ie. Firstly, we explain display method using l.0㎜ × 0.5㎜ size LED. Secondly, We propose to the new package of 40pin Thin-QFN(6.0㎜ × 6.0㎜) control IC. As a result, the proposed display method is shown good accuracy at dark room and a long range, furthermore the display technique method is improved for character recognition and real-time display.
