The purpose of this study was to analyze the alcohol volume consumed and alcohol dependancy according to multiple rounds of drinking. Sectional data collected in 2012 as part of an International Alcohol Control Study were used, and 855 of 1,789 drinker aged 19 to 64 were conducted. The proportion of multiple rounds drinking were significantly higher in males(χ²=37.607, p<.001), students(χ²=52.466, p<.001), single(χ²=34.205, p<.001), smoking experience and stressed(χ²=40,09, p<.001; χ²=21.66, p<.001) among drinkers. In particular, the alcohol volume consumed of unmarried people, smokers, and stress groups were significantly higher than married people, non-smokers and no-stress group. The highest alcohol intake in the first, 2nd and third rounds was found in bars in the liquor trade (F=67.8g, p<0.001). The total alcohol intake increased as the number of rounds increased (F=209.993, p=0.001) and the number of drinkers who tested positive for alcohol dependency increased, using the tests RAPS4 and DSM-IV(F=129.836, p<0.001; F=94.669, p<0.001). The OR of alcohol dependancy in males was 2.3(95% CI: 1.745-3.057), unemployed was 3.2(95% CI: 1.053-9.838), smokers was 3.9(95% CI: 1.230-12.292), and stress group was 2.1(95% CI: 1.561-2.768) compared to females, employed, non-smokers, and no-stress group respectively. In conclusion, it suggests that those consuming multiple rounds drinking can become more vulnerable to alcohol harms due to its relation to smoking, stress and increased dependence on alcohol.

Monthly variation of fatness index of the shortnecked clam was investigated at Moonhangri in Namhaedo of the southern coast of Korea from April 1991 to March 1992. The standing crops of umbo stage larvae and spats of this bivalve were also investigated. The results are as follows: The ranges of a monthly average water temperature and salinity were $6.9\~23.5^{\circ}C$ and $29.6\~33.1%o$ during the investigation period. Fatness index of the shortnecked clam decreased suddenly from June to September, which seemed to be spawning season. The umbo stage larvae of the clam were observed from May to November. The standing crops of the larvae were $883\;inds./m^3$ in August and$68\;inds./m^3$ in November. The observed number per ~ of the spats varied with the month and the different exposure time zones. The highest density $(1,508\;inds./m^3)$ was observed 1 hour exposure zone in August, and the lowest one $(28 inds./m^3)$ at 1 hour exposure station in April. Even the observed number of the spats below 4 mm in shell length were high in 1 and 3 hour exposure zones, the spats above 4 mm in shell length were observed mainly at 3 hour exposure zone.

Main Path Analysis (MPA) is one of the text mining techniques that extracts the core literature that contributes knowledge transfer based on citation information in the literature. This study applied various text mining techniques to abstract of the paper related with sense-of-place, which is published at Korea and abroad from 1990 to 2018 so that could discuss in a macro perspective. The main path analysis results showed that from 1990, overseas research on sense-of-place has been carried out in the order of personal identity, public land management, environmental education and urban development-related areas. Also, by using the network analysis, this study found that sense-of-place was discussed at various levels in Korea, including urban development, culture, literature, and history. On the other hand, it has been found that there are few topic changes in international studies, and that discussions on health, identity, landscape and urban development have been going on steadily since the 1990s. This study has implications that it presents a new perspective of grasping the overall flow of relevant research.

This study aims to suggest the values and utilization measures of the stone walls in Jeju Island as place assets. The discussion on this subject may serve as a breakthrough to resolve the current situation where the stone walls in Jeju Island have been focused on for their potential value not for their practical value as place assets. Moreover, specific measures to utilize Jeju stone walls may become a vehicle to seek the sustainable development of the region. This study discussed the types, functions and values of the stone walls in Jeju Island as place assets and suggested practical measures to use the structures based on their regional distribution. The in-depth discussions largely concluded that there might be five values and seven utilization measures with regard to the Jeju stone walls. The results of the study are expected to be utilized as a new indicator for the regional development of Jeju Island.

From our analysis of pedestrian walking behavior at the Daegeon underground shopping center, we think that the following changes might be necessary to improve sign placement and use. First, the discrepancy between the location of information signs and their rate of use should be reduced. Second, differences in information given by the signs that arise from problems with sign height and placement should be reduced. Third, signs should be distributed in such a way that they provide co-ordinated information about points and places. Fourth, the arrangement and placement of the signs should be considered from the view point of pedestrian walking behavior. Because there is difference in the number of installed signs and the rate of use of these signs, to increase the rate of information use it may be necessary to adjust the content and placement of the signs. Furthermore, analysis of subject walking paths shows that it is necessary for information to be offered about connections between spaces.

The purpose of this study was to investigate students' awareness on the scientific and/or technological workplaces and relevant professions in terms of accuracy, diversity and complexity. Participants were 185 7th-, 192 9th-, and 198 10th-graders in Seoul, Daegu, and Gwangju. The results revealed that students' ideas about scientific and/or technological workplaces were general in nature and were stereotyped as certain workplaces such as a laboratory, factory and garage. Their ideas did not differ significantly by grade in view of complexity. Many students also answered that the main factors affecting their ideas about scientific and/or technological workplaces were mass media and/or school education. The students' examples of scientific and/or technological professions were stereotyped as some professions, and the number of examples were very small. Students perceive the scientific professions accurately, but they have a vague perception of the technological professions. Educational implications of these findings are discussed.

The National Archives of Korea(NAK) has a mission to ingest large-scaled digital records and information from a number of different government agencies annually from 2015. There are important issues related to the digital records and information transfer between NAK and agencies, and one of them is how to configure deployment of digital repositories for the archives management systems. The purpose of this paper is to offer the way to design it by examining the checkpoints through the whole life cycle of digital records and information in the archives management systems and calculating the amount of ingested digital records and information to the systems in 2015 and deploying the digital repositories configured according to the amount the records and information. Firstly, this paper suggests that the archives management systems in NAK should be considered and examined into at least three different parts called Ingest tier, Preservation tier and Access tier in aspects to the characteristics of the flow and process of the digital records and information. Secondly, as a results of the calculation the amount of the digital records and information ingested to the archives management systems in 2015 is sum up to around 2.5 Tera bytes. This research draws several requirements related to the large-scaled data and bulk operations which should be satisfied by the database or database management system implemented on to the archives management systems. Thirdly, this paper configures digital repositories deployment according to the characteristics of the three tiers respectively. This research triggers discussion in depth and gives specific clues about how to design the digital repositories in the archives management systems for preparing the year of 2015.

The purpose of this study is to assess the play and leisure status of children in Korea. The subjects of the study were 564 children in elementary, middle, and high school classes in four districts of Seoul and one rural district in Gyeonggi Province. We surveyed and analyzed the objects, time, place and cost of both play and leisure and investigated the differences according to age, region and sex. The results of this study can be summarized as follows. First, the children's play and leisure subjects were more likely to be friends than family members, and the proportion of fathers among the parents decreased with increasing age. Second, the children spent most of their play and leisure time on media related activities. Third, unlike in the past, the children's places of play and leisure were very diverse and included many adult or commercial places, such as cafes and karaoke studios. Fourth, there were no differences in the cost of play and leisure, depending on the age or sex of the children, but there were regional differences.
