In building structure, the story height can be minimized by providing openings in beams which serves for the utility equipments passing through. The dead space in false ceiling thus put to economical use in the form of a substantial reduction in materials and construction cost. In the case of steel structure, there is no critical risk in the structural strength because of reinforcing methods of stiffness and steel plate but in the case of reinforced concrete structure, proper provision should be made in designing these openings, otherwise there is a risk that these opening will possibly weaken the structural strength of the building frame to a critical degree. In this paper, for the numerical analysis of the reinforced concrete beams with circular opening in the web, expecting stress concentration of the circular opening, reinforcing methods were studied. Twenty test pieces with each different reinforcing methods were tested and their resisting forces were defined. From the numerical analysis and test results, the followings were founded; ① high shear stress distributed around the openings reduce the shearing strength, ② from the numerical analysis, the maximum tensile stress occurred at opening nodes 1,7, these phenomena were agreed with the test results, ③ reinforcing method around openings haute to carried out for stopping diagonal cracks, and ④both, by steel plate, and wire mesh, are effective reinforcing methods.

본 연구는 고령자의 우울과 기능 및 삶의 질에 대한 현수 복합 운동의 영향을 파악하여 일상생활기능과 삶의 질에 미치는 것에 대해 알아보고자 하는 것이다. 연구방법으로는 D시에 소재한 M병원의 요양 노인 중 65세 이상의 대상자 중 40명의 고령자를 현수 복합 운동 프로그램 그룹(n=20)과 대조군(n=20)으로 무작위 배정하여 비교하였다. 이는 현수 복합 운동프로그램과 현수가 없는 같은 프로그램을 12주 동안 주 2일 60분간의 실험 전후를 분석하였다. 또한 삶의 질은 자기효능감을 사용하여 측정하였다. 그룹 내 비교를 위하여 대응표본 t-검정을 그룹간의 비교에는 독립표본 t-검정을 사용했습니다. 연구결과 실험 군은 대조군과 비교하고 모든 평가(GDS, FIM, 자기 효능감)에서 유의하게 높은 변화를 나타났다(p<. 0.05).그리고 실험군 그룹의 일반적 자기효능감에서는 큰 변화가 없었다(p>0.05).본 연구를 통하여 알 수 있는 것은 현수 복합운동프로그램이 노인들의 삶의 질 개선에 효과적인 것으로 나타났다. 또한 실험을 프로그램은 노인의 우울과 일상생활기능과 삶의 질 개선에 도움이 될 수 있다. This study examined the effects of sling-complex exercise on depression, function, and quality of life in the elderly. As a study method, 40 elderly people aged 65 years or older among nursing homes in M Hospital located in D city were compared randomly with the Suspended Combined Exercise Program group (n=20) and control group (n=20). This was measured using the GDS for depression before and after the intervention for 60 minutes, two days a week for 12 weeks for the combined exercise program with a sling and the same program without a sling. In addition, the quality of life was measured using self-efficacy. For comparison within the group, a paired t-test was applied, and a two-sample t-test was used for the comparison. After the intervention, the experimental group showed a significantly greater change in all evaluations (GDS, FIM, and self-efficacy) compared to the control group (p<0.05). Moreover, there was no significant change in the general self-efficacy of the control group (p>0.05). Overall, the sling complex exercise program is effective in improving the quality of life of the elderly.

본 연구는 사립유치원의 재정운영 현황을 분석하여 현실에 적용 가능한 재무·회계 규칙 제정을 위한 기준을 도출하는 데 목적이 있다. 이를 위해 법인과 사인 사립유치원 총 네 곳을 선정하여 원장을 면담하였다. 사립유치원의 재무·회계 관련 재정운영 현황을 분석한 결과, 개인이 운영하는 사립유치원이 특히 열악한 것으로 나타났으며 이의 개선을 위해 다음과 같은 기준을 향후 재무·회계규칙에 반영할 필요가 있다는 시사점을 도출하였다. 첫째, 사립유치원의 재무·회계 관리를 개선하기 위하여 재무·회계업무 직원을 배치하거나 시스템을 구비하는 일이 필요하다. 둘째, 건물의 유지 보수 등을 위한 일상적인 경비지출이 아니라 규모가 큰 자금이 필요한 경우 차입금 또는 적립금을 허용하는 방안이 요구된다. 셋째, 예산분야에서 세출예산의 이월 및 계속, 추가경정예산 등 예산 제도에 대한 이해가 필요하며, 예산의 기본원칙을 지키도록 해야 한다. 넷째, 회계처리는 단식부기를 기본으로 하되 단식부기의 문제점을 보완할 필요가 있다. 다섯째, 관할청의 감사도 회계의 투명성을 보장하는 기제가 될 것이다. The purpose of this study was to develop a universal standard for finance and accounting applicable to private kindergartens. Four private kindergartens, including 2 kindergartens established by foundations and 2 kindergartens established by individuals were selected for study. The findings reveal poor fiscal management, especially in the private kindergartens established by individuals. In order to improve the current conditions, the following steps are suggested. 1) Provide experts or staff with special expertise to furnish information regarding the implementation of a fiscal management system. 2) Admit loans or reserve funds to repair decrepit facilities and buildings. 3) Follow a consensus of universal budget principles, including a revised supplemental budget and an established plan for budget carry-over. 4) Establish better bookkeeping with special attention to single entries. 5) Ensure transparency through periodical auditing provided by the Educational Office.

최종인(Jong In Choi),한승혜(Seung Hae Han),박경호(Kyong Ho Park) 한국발육발달학회 1999 한국발육발달학회지 Vol.7 No.1

The purpose of this study was to investigate the degree of riskiness caused by lack of exercise according to the characteristics of physical fitness related to grown-up male`s health and to propose a guide for exercise prescription needed to prevent it as minimum as possible. A hundred seven male subjects at the age of thirties, forties and fifties were recruited to measure physical fitness related to health. As a result It was shown that all the factors of physical. fitness tended to decrease consistently as the age increased. In particular, the flexibility decreased considerable at the age of forties. the power, flexibility. agility and balance decreased considerably at the age of fifties and the muscular strength tended to decrease as the age increased In aspects of maintenance plan for healthy physical fitness according to the age group. the maintenance of heaths! physical fitness after thirties could be delay of decreasing tendency through the hard training of insufficient physical fitness factors. in this respect, it can be speculated that exercise program according to the age group is emphasized on flexibility training for the forties and power, flexibility. agility and balance training for the fifties.

The purpose of this research is to develop the technology for the synthesis of (Ti, Al)N powder, which shows simultaneously the excellent properties of TiN and AlN, from the Ti-Al intermetallic compounds by the direct nitriding method. The effects of variables such as temperature, Ti-Al intermetallic compounds (TiAl₃, TiAl and Ti₃Al) were investigated by TG, XRD and SEM. The (Ti, Al)N powder can be easily synthesized from the intermetallic compounds by the direct nitriding method. Among the intermetallic compounds, the nitriding behavior increased with TiAl>Ti₃Al>TiAl₃, as the difference of diffusion coefficient for nitrogen in each materials. The ternary nitride such as Ti₂AlN and Ti₃Al₂N₂ can be synthesized by the direct nitriding method, although the ternary nitride coexist with TiN and AlN. The ternary nitrides are stable below 1400℃, but these are gradually decomposed into TiN and AlN above 1400℃.

林大銑,宋圭鉉,朴敬浩,朴暎緖,李玩永 中央醫學社 1963 中央醫學 Vol.5 No.4

A case of secondary aspergillosis of the left maxillary sinus following chronic sinusitis in a 42 year old male coal miner specialist is reported. His chief complaints were nasal obstruction and postnasal drip of several years duration. Roentgenogram revealed marked and moderate shadow in the left and right maxillary sinuses respectively. Significant operative findings included almost paper-thin bony walls of the left maxillary sinus, and small amount of yellow greenish purulent material was drained, followed by yellowish brown semisolid tissue on further curettage. The latter specimen was found to be essentially mass of fungi, showing numerous distinctly septate, branching hyphae on the Papanicolaou stain of the direct smears of the cut surface of the specimen, and Hematoxylin-Eosin and Periodic Acid Schiff stains of paraffin sections. Pertinent aspects of clinical and pathological differential diagnosis between aspergillosis - and mucormycosis, are described. Aspergillosis presents usually benign course, with insignificant chief complaints as our case, whereas mucormycosis is most frequently associated with uncontrollable diabetics, and run usually acutely fatal course. There are three main types of ucormycosis-cerebral, pulmonary and intestinal. The characteristic broad nonseptate branching hyphae of mucor, and marked affinity to the blood vessels,, penetrating the tough walls of arteries, with thromboses and infarction, readily differentiate aspergillosis from mucormycosis.
