This article presents suitable model for small portfolio selection. Since the small portfolio selection model is formulated as a Gomory's cutting plane algorithm of Integer programming, the value of decision variables in the optimal solution of this model is an integar, and therefore the stocks exchange hands becomes a round-lot. Accordingly, transaction commission can be reduced. This model can be reduced that input-data by selecting the stock. (i.e. classification by industry of stocks) The small portfolio and small investor can be profitable selection to stocks. The cost due to the diversification of the stocks holds offsets the unsystematic risk.

노인주거안정을 위한 역저당(Reverse Mortgage) 제도 도입 가능성

임경수,조덕호 韓國老年學會 1999 한국노년학 Vol.19 No.1

역저당제도는 집을 가진 노인이 정년 퇴임 후에 소득이 없거나 생활비가 부족할 경우 주택을 담보로 금융기관으로부터 주택의 소유권을 가지고 있으면서 주택자산의 유동화를 통하여 매월 일정한 소득을 생을 마감할 때 까지 지원받고, 사망 후에는 그들 주택이 금융기관에 귀속되는 제도로 주택의 소유권이 보장되면서 동시에 생활안정이 보장되는 노인복지제도이다. 이 제도는 운영방법에 따라 다양하게 분류할 수 있으나 기본적으로 노년에 일정한 소득이 없는 경제적 취약계층에게 월 생활소득을 지원함으로써 안정된 노후를 보장하는 새로운 노인복지제도이다. 본 연구는 이러한 역저당제도를 우리 나라에 적용할 때 그 적용가능성과 수요를 분석하고자 한다. 특히 서구문화와는 달리 전통적으로 가족중심으로 부가 세습되는 사회·문화적 풍토에서 노인계층에게 이 제도가 어느 정도 수용가능한지 또한 실질적으로 노인복지향상에 어느 정도 기여할 수 있는지 등에 대한 시론적 논의를 제시하는 데 있다. 노인들에 대한 면접설문조사결과 아직까지 역저당제도에 대한 인식이 부족하기는 하지만 노인의식의 변화, 핵가족화, 자녀세대 의식의 변화 등으로 차츰 그 수요가 증대될 것으로 판단된다. 역저당제도에 대해 정책적, 제도적 장치가 효과적으로 마련된다면, 이 제도는 실질적으로 노인의 주거안정과 생활안정을 동시에 달성할 수 있는 새로운 노인복지정책으로 정착할 수 있을 것으로 나타났다. The objectives of this study are to solve the housing and income problems of the elderly by introducing a reverse mortgage system, which is one of the liquidation method of the housing assets of the elderly, in housing financial market in Korea. In order to achieve these objectives, this study reviews the reverse mortgage system in housing financial market and social welfare aspect. It also surveys the housing status and monthly living income of the elderly and analyzes their recognitions on the reverse mortgage system by the field survey. Based upon these analyses, it examines the feasibility of reverse mortgage system in Korean housing financial market and will suggest some policy implications for solving the housing and income problems of the elderly. The major findings of this study are as follows: the elder prefer to live with their spouse in their housing without moving out to the welfare facilities or their children's housings. A significant number of the elderly answer the positive response in using the reverse mortgage system but a similar number of the old people have no idea on this financial system. They want to transfer their housing assets to their children after death because they do not have an adequate social system for the liquidation of their assets even though they like to live with their spouse in their own housing. It means that there are lots of potential demand on the reverse mortgage system. Therefore, the central or local government must develop the reverse mortgage system, which is the liquidation method of the housing assets, for solving the residential stabilization and month living cost problems of the elderly. And also the public sector elaborates social welfare systems and reports them to the elderly in order to resolve their social problems.

Background: Cardiovascular injury is a potentially fatal complication of blunt chest trauma. The diagnosis of cardiovascular injury in blunt chest trauma is not easy because of concomittent injuries of thoracic cage or lungs and early death from cardiovascular injury. Diagnostic tools such as electrocardiography or cardiac enzyme studies are not specific to cardiovascular injury. Two-demensional echocardiography can visualize anatomic and functional disturbances from cardiovascular injuries in patients with blunt chest trauma. Purpose: This study was designed to evaluate the usefulness of echocardiography in detecting cardiovascular injury of patients with blunt chest trauma. Methods: We performed echocardiography for detecting cardiovascular injury in 151 patients with significant blunt chest trauma including sternal fracture, multiple rib fractures or pulmonary contusion. Echocardiography was performed within 6 hours since patient arrived emergency department. Electrocardiography was traced on arrival and 24 hours after admission. Serial determinations of cardiac enzymes including MB fraction of creatinine phosphokinase were also performed every 8 hours after admission. Results: 37(25%) patients had echocardiographic evidences of cardiovascular injury. Abnormal echocardiographic findings were 10 pericardial effusion, 9 regional wall motion abnormality(RWMA) of right ventricle, 5 aortic injuries, 4 reduced left ventricular ejection fraction, 3 RWMA of left ventricle, 2 right ventricular dilatation, 2 valve injuries, and 2 other cardiovascular injuries. Electrocardiographic abnormalities were associated with echocardiographic findings. However, CK-MB/CK ratio was not associated with echocardiographic findings. Significant proportion(65%) of patients with abnormal echocardiographic findings needed cardiovascular management during hospital stay. Conclusion: Two-dimensional echocardiography is useful for detecting cardiovascular injury. Echocardiographic abnormality in blunt chest trauma is associated with high probability of need of cardiovascular management.

The design of experiments says that it's statistical method planning to get the best information of quality characteristics with the least number of times of experiments. This paper aims at analyzing the process capability and at determining an optical condition by experimental designs using the 2-way classification with repitition in order to maintain lower Nacl content and to refine both or a very small quantity of fatty acid and various magnetic jons in the glycerin to use ion exchange resin treatment process. An optimal condition of each level combination in both of passing temperature of cation exchange resin(A₁, A₂, A₃) and of anion exchange resin (B₁, B₂, B₃) is A₃B₃The process capability index is improved form 0.63 to 1.40 and is interpreted as a desirable state. This analysis of process capability by experimental designs will contribute to improving productivity and quality of products.

Since the shoes sewing has been labor-intensive and produces on a large scale, the variation of items sustains much loss and restrict the improvement of labor productivity. The design of the multi-item and small-quantity system requires a survey and investigation for the production system. In this paper, through the questionaires, we analyze and evaluate the line layout, productivity, organization, administration, subsidiary facilities, and work environment. The results of this study may contribute, as a fundamental data, to the plant rationalization, a variety of activities for cost curtailment, and a design of line layout.
