Purpose: This study is a descriptive survey to find out musculoskeletal symptoms in care workers working at medical welfare facilities for elders and factors affecting such symptoms. Methods: Data were collected from 115 care workers selected through convenient sampling from 6 medical welfare facilities in Seoul and Gyeonggi-do during the period from May 15th to May 19th. 2006. The Korean version of Job Content Questionnaire (JCQ) were used. Result: Of the subjects, 81.7% complained of musculoskeletal symptoms in two or more parts of their body. The frequency of body parts with musculoskeletal symptoms was high in order of shoulder, leg/foot, waist, neck/hand/wrist/finger and arm/elbow. The average job insecurity instability in the age group of 50-59 was 9.19, the average degree of regular exercise was 59.68. and the average job demand in those diagnosed with musculoskeletal diseases was 47.06, and the average job demand in those wounded during exercise or by an accident was 47.78, and all these were statistically significant. The heavier physical load in their work was, the higher their complaint of musculoskeletal symptoms was. In the lower social support group, the degree of complaint on musculoskeletal symptoms was remarkably high. Conclusion: The physical load of their duty and social support worked as the factors affecting musculoskeletal symptoms in care workers.

Korea owns vast amount of apartment houses no less than those of world prominent countries, but did not pay enough efforts to maintain existing apartment houses and develop policies to reuse them due to growth driven policy of housing supply like construction of new houses. Korea constructed tremendous amount of houses in short period through government led forced house supplying policy, and resulted in excess houses such that present house supply rate happened to be reaching 110%. However, recently there are growing demand of change in housing policy due to social environmental changes like low birth rate and aging of society etc and nationals' demand for improvement of residential quality. When such social changes are demanded and 80% of apartment houses in Korea are less than 20 years old, renovations and remodeling of apartment houses are anticipated to emerge as important matter. In particular, the apartment houses in Seoul and the 1st generation new cities like Bundang and Ilsan etc have passed considerable period of time after construction and require safety measure, it is quite impending to loan programs for the maintenance of existing apartment houses. The objective of this study is to compare and analyze the system of loan programs about apartment houses of Japan, and then to propose to accelerate loan programs about maintenance for apartment houses in korea.

This paper examines the individual and social values of tour and recreation activities related to the characteristics and attractions of parks in urban area through a questionnaire. The data for this research consists of 2,942 samples based on interviews in sixteen parks in Daegu area. Implications of the findings for urban parks design and tour and recreation policy are discussed. Travel cost method and contingent valuation method are applied essentially. These methods yield a reasonable estimation of the relationship between tour and recreation values of the parks and the visit rate which can be used to estimate demand functions for tour and recreation experiences provided by a site. Semilog-type models can be used to estimate the use of the park. Finally, the tour and recreation value of each park per user-day is estimated by the total experiences of the users. This study is a modest but important step in the investigation of urban parks and recreation site demand and values. Many of the developments in contingent valuation method and travel cost modeling should now be applied to the urban scale parks and recreation sits. Such studies will contribute significantly to the improvement of methodology for tour and recreation values measuring, especially to individual and social benefits for the urban parks, and provide the much needed guidance for the allocation of scarce tour and recreation resources.

This paper presents optimal operational scheduling model and economic assessment of Li-ion battery energy storage systems installed in non-residential customers. The operation schedule of a BESS is determined to minimize electric bill, which is composed of demand and energy charges. Dynamic programming is introduced to solve the nonlinear optimization problem. Based on the optimal operation schedule result, the economics of a BESS are evaluated in the investor and the social perspective respectively. Calculated benefits in the investor or customer perspective are the savings of demand charge, energy charge, and related taxes. The social benefits include fuel cost savings of generating units, construction deferral effects of the generation capacity and T&D infra, and incremental CO2 emission cost impacts, etc. Case studies are applied to an large industrial customer that shows similarly repeated load patterns according to days of the week.

In order to solve social exclusion and segregation phenomenon and to realize social integration, the necessity of social combination and consensus has been presented and existing conception about the public lease apartment confronts a turning point due to the diversification of apartment supply system. With this social background, Eunpyeong New Town Project implemented by Seoul Metropolitan Government is the first example that supplied diverse apartments for social integration. Survey was made upon the residents aged 20 and over and living in combination apartments, lease apartments and common apartments for private ownership in the Enpyeong New Town Apartment Complex in section 1 area, and the survey sheets filled up by the respondents were collected by personal visits or by using specified gathering spots. Summary of study results is as follows: Firstly, regarding the combination method, respondents preferred the irregular combination of lease apartment units and common apartment units in the same apartment building at the top, analyzing by survey groups marked that residents of common apartment with initial ownership responded not to choose combination apartment complex or combination apartment in future. Secondly, the living consciousness with neighbors revealed that respondents were generally satisfied without difference between the residents of lease apartment and common apartment. As the demand and policies for diverse lease apartments are increasing recently, Eunpyeong New Town Project aimed for positive social integration and consensus will be evaluated as model case for social combination apartment in future. And it is necessary to introduce the policies that consider the differences in consciousness and interest of the residents among the lease apartments and common apartments.

Although the demand and awareness of public regarding social-cultural functions of agriculture and rural areas would increase recently, the sustainability of them has continuously decreased. To derive policy directions for improvements of social-cultural functions of agriculture and rural areas, This study analyzed willingness to pay for social-cultural functions of agriculture and rural areas and its determinants by uisng contigent valuation method. The results show that the willingness to pay for social-cultural functions of agriculture and rural areas is positively affected by awareness of the importance of agriculture, interest in problems regarding agriculture in Korea, awareness of social functions of agriculture, and experience in rural life. These results would imply that policies for the improvement of public awareness and experiences increase the value of social-cultural functions of agriculture and rural areas. In addition, the results imply that more diverse education programs and activities are required in order to change awareness of future generations in response to decreases in population having experiences in agriculture and rural life due to urbanization. Lastly, the results show that the average willingness to pay for social-cultural functions of agriculture and rural areas is about 35,600 won, and total willingness to pay for social-cultural functions of agriculture and rural areas is about 998.3 billion won. This is much larger than the government budget on enhancement of social-cultural functions of agriculture and rural areas in 2019. This difference between government budget and the total willingness to pay implies that Korean government would be required more positive policies to maintain and enhance social-cultural functions of agriculture and rural areas.

현재 철도계획에 이용되고 있는 교통수요예측 지역간기종점(OD)자료는 국가교통데이타베이스(KTDB)를 이용하고 있다. KTDB의 자료는 우리나라 지역간 총통행량을 조사한 후 도로, 철도, 항공등으로 배분하는 방법을 이용하고 하고 있다. 그러나 철도의 경우는 철도역이 기존의 존과 일치하지 않거나 1개존에 다수의 철도역이 존재하여 Connector가 연결되지 않아 적용 방법상에 문제점이 있는 것으로 나타났다. 이로 인해 KTDB를 이용한 철도부분의 교통예측은 다른 교통수단에 비해 신뢰성이 크게 떨어지고 있다. 본 연구는 이러한 문제점을 검토 분석하고, 신뢰성을 높이기 위해 집계모형(Aggregate Model) 기법을 활용한 철도의 교통수요예측 방법(직접수요추정 : Direct Demand Estimation)을 제안하였다. 본 연구에서는 집계모형에 지역간의 인구, 거리, 산업체종사자수, 자동차대수, 도로연장등 사회경제지표의 연관성을 분석하여 철도분야 수요예측의 오차를 최소화할 수 있는 방법을 연구하였다.

In our increasingly aged society, the term centenarian, meaning people 100 years old or older, is used more and more frequently. Indeed, anticipating long life, middle-aged to advanced-age people have changed their lifestyles to purchase goods for themselves. In addition, as the social trend of careful grooming for positive appearance spreads within the Korean society, the demand for senior male cosmetic products is likely to grow as the society ages further. However, previous large studies on the market for senior male cosmetics are limited. Since information is lacking about senior male consumers' awareness of cosmetics, this study examined their use of cosmetic products, purchase behaviors, and demand for cosmetics in order to explore correlations among interest levels in appearance, cosmetic purchase behavior, and cosmetic demand levels through diverse factors related to multiple variables. The results of this study were as follows : First, the more senior men managed their practical appearance, the more frequent their functional and psychological purchase behaviors. Second, the higher their practical purchase behavior, the stronger their demand for reasonable cosmetic prices. Third, the higher their value-oriented purchase behavior, the stronger the demand for greater product diversity. This study investigated men aged 50 or older residing in Seoul. Therefore, generalizing the findings of this study will be limited. Relevant subsequent studies should examine men aged 50 or older in each Korean region and more clearly identify the correlations among interest in appearance, cosmetic product purchase behavior, and cosmetic product demand using various factors related to multiple variables.

최근 코로나 19 사태로 인한 경기 위축에도 불구하고, 재택근무 증가로 집에 거주하는 시간이 늘어나면서 주거환경에 관한 관심이 커지고 있으며, 이에 따라 리모델링에 대한 수요가 증가하고 있다. 또한, 정부의 부동산 정책 또한 규제 정책에서 주택공급 확대 방향으로 전환하면서 이에 따른 인테리어, 가구업계의 매출에도 가시적인 영향이 있을 것으로 예상한다. 정확한 수요예측은 재고 관리와 직결되는 문제로 정확한 수요예측은 불필요한 재고를 보유할 필요가 없어 과잉생산으로 인한 물류, 재고 비용을 줄여줄 수 있다. 하지만 정확한 수요를 예측하기 위해서는 지속적으로 변화하는 경제동향, 시장동향, 사회적 이슈등 외부요인을 모두 고려하여 분석해야 하기 때문에 어려운 문제이다. 본연구에서는 가구 부자재를 생산하고 있는 제조업체에 대하여 신뢰성 있는 결과 도출을 위해 인공지능기반 시계열 분석 방법으로, LSTM 모형, 1D-CNN 모형을 비교 분석하였다.
