Purpose: This study presents the analysis on space usage of delivery departments in regional public hospitals. The results intention is to achieve improvement of the delivery environment for the mothers and newborns regarding exposure prevention and efficient infection control. The purpose of this study is to provide fundamental data for architectural plans and guidelines for the delivery department. Method: The investigation and analysis were based on research papers, legal systems, public medical statistical data, and the architectural floor plan drawing. For research, 20 regional public hospitals with an operating delivery room were excluded. Regarding data accessibility, 15 regional public hospitals were selected. Results: To overcome the increased vulnerability of the delivery department, the research results of basic data is provided for the establishment to address urgent needs and rapid response. Thus, the research results are as follows: Firstly, the delivery department needs to respond promptly according to the type of patients. For example, in a case of emergency surgery, a connected circulation plan with the related departments is needed. Secondly, for the environment of the delivery area, alleviating anxiety is imperative for pregnant patients and guardians, labor, childbirth, and recovery. Therefore, these needs must be addressed for treatment space and circulation. Lastly, the delivery department is classified into three areas for analysis: access area, treatment area, and support area. In most of the delivery departments of the 15 selected hospitals, there is no space for the access and support area except for the labor and delivery rooms in the treatment area. For the access area, a waiting area, changing room for pregnant women and guardians, and a storage space for contaminated linens are required for infection prevention, safety, and efficiency. For the treatment area, childbirth processes and circulation should have space reserved for labor, delivery, recovery, examination, and treatment. In preparation for an emergency during childbirth, emergency response measures and supporting space needs to be established. For the support area, circulation and rooms are to be designed for medical staff support, activity space, storage and transportation of equipment, and urgent medical treatment. Implications: Along with the low fertility rate and the decrease of medical institutions that operate delivery departments, for the purpose of establishing a public medical service system and a healthy medical environment for mothers and newborns, the researched information demonstrates basic data on space plan of delivery departments in regional public hospitals.

This study is to propose the ecosystem service valuation method as a complementary or alternative tool to overcome the limitations of the contingent valuation method(CVM), typically used to assess social benefits in preliminary feasibility studies. With an increasing interest in natural and environmental restoration projects, we assessed social benefits with theses CVM and ecosystem service valuation method from a case of Janghang wetland restoration project and compared the extent of the two social benefits. For quantitative evaluation of ecosystem services, the biophysical quantity for each ecosystem service indicator was calculated and then converted into currency (KRW) units to estimate the economic value of ecosystem services. The four ecosystem regulating service indicators were selected including greenhouse gas capture/storage, air pollution, water quantity and quality regulation. The amounts of CO₂ sequestration and storage as a ecosystem's greenhouse gas regulating service in the study area were 73.04 tCO₂/yr and 5,867.53 tCO₂/yr respectively. The reduction of SO₂, one of air pollutant gases by ecosystems was calculated to be 180.27 kg/yr, the reduction of NO₂ to be 378.90 kg/yr, and the reduction of fine dust (PM10) to be 9,713.92 kg/yr. The amount of freshwater regulating service by the ecosystem was estimated to be 459,394,319ℓ/yr, and the amount of nitrogen in freshwater removed by the ecosystem was 78.00kg/yr. Study results show that the benefits derived from the CVM were KRW 227.8 billion over the 30-year analysis period and those from the ecosystem service valuation method were KRW 41.4 billion for regulatory services and KRW 148.8 billion for cultural services, totaling KRW 189.5 billion. With KRW 184.8 billion of the total costs, the benefit/cost ratio using the CVM was 1.23 and that with the ecosystem service valuation method was 1.03. This study implications include that the CVM and ecosystem service valuation method can be applied together to assess and compare social benefits for natural and environmental restoration projects.

An attempt is made to predict the shelf life of seasoned anchovies packaged with laminated film, composed of polyethylene terephthalate (PET) and ethylene vinyl alcohol (EVOH). First, a descriptive sensory analysis is carried out to determine the principal sensory quality index in seasoned anchovies. Then, the physicochemical quality index with high correlation to the principal sensory quality index is determined accordingly. Subsequently, with the physicochemical quality index, the shelf-life is estimated by using the Arrhenius equation. As for the sensory quality index, 'color' is determined as a principal sensory quality index. For all samples stored at 3 different temperatures (25, 35, $45^{\circ}C$), it is observed that the sensory score is shown to be over 2.5 until 60 days of storage period, which is the lowest acceptable level. In addition, the b-value, as a physicochemical quality index, is determined to have a high correlation to the sensory quality index. Further, the activation energy and the Q10 value for the b-value by the Arrhenius equation is found to be 11.24 kcal/mol, 1.385~2.011, respectively. Thus, it can be concluded that the shelf life of seasoned anchovies packaged with PET/EVOH film is estimated to be 279.44 days when stored at $20^{\circ}C$.

Modern museums that started from 17th century in Europe have played a role of storage for collections of the upper class as a form of private museum. Since 18th century the publicity has been more emphasized in the society of Europe and there became a public museum that serves as a institution for social education. In addition to this, the mass production that began with the Industrial Revolution relieved the working hour of the public and they started to spend their more time for visiting museums to have social education. In korea there constructed a lot of public museums after economic development and people experienced the social education and the cultural events. However, there raised questions on security issue regarding relic because of growing number of visitors to the museums. Due to this, the museums asked a surveillance system for their relic. But the museums don't have enough research on this nor understanding the current situation. Because the relic in museums of history has a money value, the anti-theft system is more focussed. In addition to the direct surveillance system with staff or closed-circuit television(CCTV), the indirected system with visitor's mutual surveillance in conjunction with spatial structure has to be researched. This study is to understand the relationship between surveillance system and spatial structure with reference to korea's national and public museum of history. With the results of the research, the study provides a planning guideline to the museum architecture to prevent security problem.

Purpose : The purpose of this study was to examine the nurses' needs for the spatial composition of geriatric hospital. Methods : The survey method was used for collecting the data. The subjects were 110 nurses who worked at 6 geriatric hospitals in Busan. They answered the questionnaire by the self-administered method. The questionnaire consisted of items which asked the spatial composition of patient room, bathroom, dining space, resting space, care-givers' room, and garden. Results : 1) The patient room using a bed on ondol floor would be useful. Also, it would be desirable that most patient rooms consisted of 4 or 6 persons per patient room and the others were 1 or 2 persons per room. 2) The bathroom for only patients and the shower room for their families or care-givers are needed in the geriatric hospital. 3) The dining room for patients in each floor would be useful to old patients. In addition to that, the cafeteria for their families or care-givers are needed. 4) The resting space for patients and their families, for the staff, and for care-givers are needed. 5) The personal locker and refrigerator are necessary fixtures in care-givers' room. Also, table, sofa, sink, and shower booth are also needed. 6) On the base of activities of care-givers, the space for preserving, washing, and heating foods are needed. Also, the storage space for personal items and the fitting space are needed. Implications : The results of this study would be the fundamental data for space planning of the geriatric hospital.
