This study explored the characteristics, housing deficits and expectations for support programs of low-income renter households in housing poverty in order to provide housing policy development and improvement information. Microdata of the 2014 Korea Housing Survey was utilized as secondary data for this study. A total of 2,508,672 low-income renter households (weighted count) in the bottom 40% income ranks of entire general households living in private rental units were selected as study subjects. The major findings were as follows. (1) One point four percent of the subjects were living in non-house living quarters (e.g., shanties, vinyl greenhouses, container houses, and mud huts), 1.4% were in dosshouses, 9.9% were in basements, semi-basements or rooftop units, and 8.2% were in sub-standard units. (2) Among the households whose housing costs burdens were measurable, 75.7% were found to have housing cost burdens to pay 30% or more of their household income towards housing costs (rental costs and maintenance costs), but only 7.5% of the burdened households received a housing voucher. (3) Eighty-one percent were found to be in a housing poverty status as defined by the researcher; in addition, low-income renter households in housing poverty in Seoul tended to have a greater proportion of households headed by females, the elderly, and be persons with low-education or disabilities. (4) Households in housing poverty showed greater expectations for financial support and/or extended provisions of public rental housing than other low-income renter households.

The main purpose of this study was to investigate attitudes toward mental illness and the mentally ill of psychiatric nurses in Korea and to identify the relationships between the nurses' attitudes and demographic variables. Subjects in this study were 122 psychiatricnurses and 111non-psychiatric nurses in active service at 12 hospitals in Seoul. The insrtument used for measuring attitudes was a questionaire developed by Cohen and Struening (1962) referred to as the“Opinions about Mental illness(OMI) Scale”made up to 51 Likert-type items. The findings of this study indicated hatnurses showed negative attitudetoward mental illness and the mentally ill: Very high on social restrictiveness (factor D), low on Mental Health Ideology (factor C), and Interpersonal Etiology (factor E). Since the high score on Factor A, B and the low score on Factor B, C, E reflect a negative altitudes toward mental illness, this study population related extremely negative attitudes compared to any other surveys. And of the demographic variables that related to their attitudes the education degree and the kind of the hospital in active service showed very significant differences. On the basis of the investigation the findings indicated the followings; 1) Althohg attitudes toward mental illness and the mentally ill of psychiatric nurses were not significant differences from non-psychatric nurses, there was a trend that attitudes of psychaitric nurses did show more negative responses rather than those of non-psychiatric nurses. 2) Demographic variables that relate to their attitudes on the OMI scale were the education degree of the respondent and the kind of their hospital in active service. 3) About attitudes toward mental illness and the mentally ill baccalaureate nursesshowed more positive attitudes in Factor A (Authoritarianism), Factor C (Mental Health Ideology) and Factor D (Social Restrictiveness) than diploma program murses. 4) Nurses in active Service in the private hospital revealed more positive attitudes(A,B,C,D) except Factor (E) than those in the national or public hospital. 5) The ages, duration of work, wanted or unwantedG roup of psychiatric ward and satisfactory level of psychiatric nursing service were non-significant.

Fishing village is becoming the central base of fishing industry and it plays a major role. However, there is a decrement of marine resources and some difficulties with the deterioration of fishing industry management. In order to solve these problems, there should be some developments(e.g. fishing village toursim development) on various undergoing government and the private organization programs. Nevertheless, there are not guidelines for fishing village tourism development to utilize for practical business. Therefore, it is necessary to understand the current status and guidelines regarding the development of fishing village for coastal planner. The primary purpose of this study is to investigate the characteristics of fishing village development works in Korea and Japan. The second purpose is to identifie success factors after analyzing individual success cases. Based on evidence from the literature and a dialogue with village leader, a literature review on extracting success cases for guidelines were selected according to criteria such as the degree of contribution to an increase in income of the fishing village, the degree of contribution to an increase in consumption of marine products using local natural resources, the number of tourists that visits the village. Finally we propose guidelines for future fishing village development projects. The guidelines based on the successful cases, as well as the major factors about the objectives and direction of fishing village tourism development, suggested as follows. 1)Plans for land use, 2)Development of tourist resources, 3)Plans for views, 4)Plans for resource protection, 5)Plans for operation and marketing.

In Korea, this is the situation at moment that the total demand of timber in 1972 is more than 5 million cubic meters. On the other hand, however, the available domestic supply of timber at the same year is only about, 1 million cubic meters. A great unbalancing between demand and supply of timber has been prevailing. To solve this hard problem, it has been necessitiated to build up the forest stocks as early as possible with fast grown species such as poplar. Under circumstances, poplar plantations which have been carryed on government and private have reached to large area of 116,603 hectors from 1962 up to date. It has now be come a principal timber resources in this country, and required the basic study on various properties of wood for it's proper utilization, since it has not been made of any systematic study on the properties of Populus grown in Korea. In order to investigate the properties such as anatomical, physical and mechanical properties of nine different species (P. euramericana Guiner I-214. P. euramericana Guiner I-476, P. deltoides Marsh, P. nigra var. italica (Muchk) Koeme, P. alba L.,P. alba $\times$ glandulosa P. maximowiczii Henry, P. koreana Rehder, P. davidiana Dode) of poplar for their proper use and development of new ways of grading processing and quality improving, this study has been made by the Forest Research Institute.

This paper presents optimized artificial neural networks (ANNs) claims prediction and decision awareness framework that guides owner organizations in their pre-bid construction project decisions to minimize claims. The framework is composed of two genetic optimization ANNs models: a Claims Impact Prediction Model (CIPM), and a Decision Awareness Model (DAM). The CIPM is composed of three separate ANNs that predict the cost and time impacts of the possible claims that may arise in a project. The models also predict the expected types of relationship between the owner and the contractor based on their behavioral and technical decisions during the bidding phase of the project. The framework is implemented using actual data from international projects in the Middle East and Egypt (projects owned by either public or private local organizations who hired international prime contractors to deliver the projects). Literature review, interviews with pertinent experts in the Middle East, and lessons learned from several international construction projects in Egypt determined the input decision variables of the CIPM. The ANNs training, which has been implemented in a spreadsheet environment, was optimized using genetic algorithm (GA). Different weights were assigned as variables to the different layers of each ANN and the total square error was used as the objective function to be minimized. Data was collected from thirty-two international construction projects in order to train and test the ANNs of the CIPM, which predicted cost overruns, schedule delays, and relationships between contracting parties. A genetic optimization backward analysis technique was then applied to develop the Decision Awareness Model (DAM). The DAM combined the three artificial neural networks of the CIPM to assist project owners in setting optimum values for their behavioral and technical decision variables. It implements an intelligent user-friendly input interface which helps project owners in visualizing the impact of their decisions on the project's total cost, original duration, and expected owner-contractor relationship. The framework presents a unique and transparent hybrid genetic algorithm-ANNs training and testing method. It has been implemented in a spreadsheet environment using MS Excel$^{(R)}$ and EVOLVERTM V.5.5. It provides projects' owners of a decision-support tool that raises their awareness regarding their pre-bid decisions for a construction project.

Research literatures (e.g. research report, scientific paper and thesis, published between 2001 and 2005) of 332 collected from KISTI, KISS, ARPC databases were investigated and analyzed to give an overview of domestic ginseng researches. Most of recent ginseng researches have been performed by private nonprofit institutions and individuals, which suggests that a role of public institution fur ginseng researches needed to be enlarged. In terms of research fields, cultivation and agricultural researches have been mainly accomplished in ginseng research. Cell physiology and reproductive function researches occupied large part of pharmacological studies, but clinical studies were relatively limited. Studies on general food products development have taken the main part in fields of food products including functional foods. As the result of analysis of 312 domestic ginseng patents by classifications of world international property organization (WIPO), it was categorized into food technology, medicinal fermentation development technology, fermentation technology, and agriculture-fisheries technology. This integrated overview of the widely scattered ginseng literatures shows current general research trends in Korea and will be able to suggest further needs on cultivation, studies and industralization of ginseng.

In Korea, utilizing and protecting the ocean from the sea on three sides can be considered the basis of national power. Recently, it has been distributed to IOT and 5G networks, and attempts to provide various information based on telecommunication infrastructure are continuing in the public and private sectors. In this study, an online survey was conducted with the aim of improving the services of marine information services (KOMC, safe and open seas) provided by the Government Agency for Oceanographic Research. Through an online survey, the survey was conducted on sites that are mainly used to survey people's need for marine information and to collect information. In addition, the survey was conducted on the UX, UI problems and improvements of KOMC, open and safe sea sites provided by the National Oceanographic Research Institute. The awareness and experience of marine information service by the Korea Oceanographic Research Institute were confirmed. Later, the previous steps of FGI also examined the usability of various users after allowing them to use the actual service. Here, the experience of collecting marine information from actual users was investigated, not just by looking at and evaluating the design of the service website and application. As a result, users presented a variety of opinions related to marine information services, including accessibility, reliability of information, providing media, and importance of information provided. The findings could be used as data to identify ocean-related data and ways to provide information required by users of various age groups and occupational groups.

Compared with public archives, personal archives are likely to disappear if creators don't preserve and manage them. So personal archives must be managed by oneself. But it's difficult to manage their archives systematically for people who don't have the expertise in archival science. Besides, there are not enough available informations. So this thesis suggests how to manage personal archives by two steps. First step is figuring out one's own archives through analyzing one's life by top-down approach and organizing them into collection. Second step is conducting archival appraisal by three steps and establishing classification schemes, describing them. Especially, this study adduce description elements using ISAD(G) for personal archives. this study also recommends using blogs on portal to manage one's archives easily. But they don't have the audit train and exporting function. So this thesis emphasizes the necessity of 'customized archive blogs'. At conclusion, this study highlights the necessity of developing education programs and manuals for people who are trying to manage one's own archives.

The purpose of this study was to identify how character education activities utilizing picture books affect pro-social behaviors of young children. The subjects were 46 children aged 5 who attended private child care centers in G city. The children were allocated to either the experiment group or the control group. The data were collected for 12 weeks and the activity sessions were provided to the experiment group 3 times a week (36 times in total). The sessions consisted of an integrated approach toward character education. Therefore, various activities were included such as listening to the stories of picture books, discussion, drama, language activities, music, mathematics, science and games. The findings of this study were as follows: The experiment group which experienced character education utilizing picture books has significantly improved their pro-social behaviors compared to the control group. The approach positively influenced the overall sub-variables such as leadership, helping, communication, initiative consideration, approach trial, sharing, empathy, and emotional control. The character education activities should be applied to character education utilizing picture books for young children because they let young children experience building up trust and learn social attitude, and influenced increase of pro-social behaviors on young children.
