Apartment is settled down as a main housing type and massive supply has been conducted since 1990's. The government has focused on the housing supply to improve the housing number and cut its price. On the contrary, the management of the housing has been neglected to get an early deterioration. Since 1995's, various ways have been made to improve and maintain the building function and performance. Among these, the long-term repair plan has played a main role to manage the housing condition and plan the repair schedule for preparing the massive cost of repair such as a roof proof, elevator change. The long-tern repair plan provides the repair time and repair rate according to various construction types. Most of the management agent apply the repair standard into the field area. But the repair time could not reflect the present condition and bring into the wrong maintenance. Therefore, the repair time for the long-term maintenance plan would be revised and reflected from the material and technology development. |n this study, it aimed at improvement for the repair time in various construction types which are provided in the long-term repair plan. For this, the 22 management agents are surveyed directly. This study shows that the repair time of the painting are correspondent to the repair time of the long-term plan irregardless of the painting materials. Most of other areas would correspondently similar to the long-term plan. This study could not include the building location, material and other haracteristics. Therefore, the further study would be needed to reflect the building and materials attributes to get the detailed repair time.

공동주택은 준공 후 일정기간이 경과하면서 사용된 자재의 내구연한에 따라 노후화 현상이 나타난다. 구성자재의 내구연한에 의해 일부부위는 짧은 시간내에 수선을 하여야 하며 어떤 부위는 장시간이 경과한 후에 수선을 하기도 한다. 이와 같이 건물에 나타나는 다양한 노후화 현상에 대해 체계적일 유지관리를 하려면 준공후 경과년수에 따른 장기적인 계획수선을 필요로 한다. 장기수선계획작성에는 건물의 공종에 따른 수선시기를 예측하여 이를 기초로 작성해야 한다. 공동주택에서 장기수선계획이 계획에 지나지 않으며 실질적인 수선에 적용되지 못하는 주요인은 앞으로 수선이 예측되는 건물의 각 부위에 대한 수선시기를 예측하지 못하기 때문이다. 이에 본 연구는 전국에 산재한 공동주택을 장수명화하기 위해 장기수선계획을 활용하여 .해당단지의 부위별 재료의 특성을 반영한 수선주기 및 수선시기를 예측하고, 공동주택 관리자가 주기적 점검, 진단, 교체 등의 사항을 유지관리 캘린더에 의해 단지별로 자동관리할 수 있는 웹기반 유지관리 시스템을 제안하다.

Annual radiation dose limit to radiation worker was substantially lowered in Korea by the adoption of 1990 recommendations of the International Commission on Radiation Protection (ICRP 60) in its legislation. On the other hand, radiation management environment in nuclear power plants is getting more worse because of the accumulation of radiation sources inside the system and the frequent need for maintenance according as the operation years of nuclear power plants increase. Therefore, Korea Hydro & Nuclear power Co., Ltd. (KHNP) has established a long-term 10 years plan from 2001 to 2010 for the reduction of radiation dose to workers. The plan is aimed for the reduction of annual dose per unit averaged over 5 years from 0.9 man-Sv in 2001 to 0.75 man-Sv in 2010 by radiation source reduction, equipment/tool improvement or new equipment development for easy maintenance, and the improvement of administration and system.

국내에서 1960년대부터 공동주택의 활발한 보급이 이루어지고 있는 반면, 공동주택의 물리${\cdot}$사회적 성능을 유지하여 수명을 연장시키기 위한 제도 및 표준적 유지관리 기법 등이 마련되지 못하여 시설안전 및 주거환경 문제가 발생하게 되었다. 이러한 현 상황 하에 공동주택의 유지관리를 통하여 주택의 수명을 증진함으로써 주택자원의 효율적인 이용이 시급한 실정이다. 공동주택의 유지관리 업무 측면에 있어 정확한 장기수선계획의 수립과 그에 따른 특별수선충당금 산정은 주택의 조기 노후화를 방지할 수 있다. 하지만 유지관리 행위주체인 주택 관리자들뿐 아니라 유지관리 대상시설물에 거주하는 입주자들에게 있어서 정확한 장기수선계획의 수립과 그에 따른 특별수선충당금의 적립에 관한 필요성 의식이 불충분한 현실이다. 장기수선계획의 미수립은 특별수선충당금의 비합리적인 적립을 허용하는 결과를 초래하고 있다. 따라서, 공동주택의 성능을 최대한 발휘하도록 하여 건물의 경제적 수명을 연장시키기 위하여 정확한 근거에 의한 장기수선계획의 수립과 그에 따른 특별수선충당금산정 방법을 제시하고자 한다.

In South Korea, minimum reserve rate, which is to satisfy reliability standard, has been determined by simulation result using WASP. But, it is still controversial whether the level of minimum reserve rate is adequate. Thus, in this study, various analyses of minimum reserve rate are being conducted. WASP uses the probabilistic simulation technique to evaluate whether reliability standard is satisfied. In this process, forced outage rate and maintenance periods of each generator play important roles. Especially, the long-term plan can be varied depending on how maintenance periods deal with. In order to model maintenance periods in the probabilistic simulation technique, WASP uses derating method. However, broad analyses have to be conducted because there are various ways including derating method to model maintenance periods which result in different results. Therefore, in this paper, 3 different maintenance outage rate modeling methods are applied to arbitrarily modeled system based on the basic plan for long-term electricity supply and demand of South Korea. Results show impact of each modeling method on minimum reserve rate.

Based on the risk factor evaluation for the file format, this paper defines the procedures for presenting the long-term preservation plan for that format and the technical information registry necessary for building the system. This is a procedure to perform a risk assessment for the format, evaluate the risk, and select a long-term preservation strategy based on the information registered in the registry and information on the external signature and internal signature of the electronic record. We also reviewed the criteria for selecting appropriate long-term preservation strategies in the process and provided the criteria for adopting each detailed strategy of migration and emulation, which are long-term preservation strategies. And we implemented this process as a long-term preservation decision support system. This system can be used to provide guidelines for the maintenance, management, service and long-term preservation of information resources of electronic records in public institutions such as National Archives of Korea and Libraries.

Compensatory changes in energy consumption and neuro-hormonal changes following weight loss make it difficult to maintain the reduced weight and may cause weight regain. Therefore, establishing a long-term weight control plan and strategy starting from the initial weight loss period is necessary. Both the patient and doctor should know that weight loss cannot occur continuously, and that maintaining weight after the weight loss period is the basic course of obesity treatment. No single dietary pattern is effective for weight maintenance, and a variety of dietary control methods - such as calorie restriction and healthy proportions of carbohydrates, proteins, fats, and meal replacements - should be used to target an integrated and healthy dietary habit. An increase in physical activity is needed for weight loss and maintenance; however, rather than recommending an excessive amount of exercise, it is better to set realistic and long-term achievable goals. It is necessary to reset the goal according to the patient's weight maintenance stage and continuously apply behavioral therapies, such as self-monitoring and stress management. In previous studies, since the degree of weight loss and changes in behavioral patterns over the course of one year were important factors in maintaining long-term weight loss, obesity therapists should closely examine patient data and behavioral patterns across a period of one year and actively intervene when needed.
