This study aimed to quantify the attitude toward doping among handball players and to identify the influence of players' demographic information, knowledge of doping, education of anti-doping on the attitudes toward doping. 385 elite handball players (193 adolescent players, 165 adult players) were participated in this study and filled in the questionnaire about demographic information, knowledge of doping, education of anti-doping and Performance Enhancement Attitude Scale (PEAS). Collected data were analyzed by Stepwise multiple linear regression. Adult players were more generous about doping than adolescents, and, adolescent players' attitudes toward doping were influenced by their gender and age. In adults, attitudes toward doping were related with only the gender. These results would be useful information to develop the effective anti-doping strategy for handball play.

Recently the company is getting bigger and has many employees. Therefore, sometimes, the uniform internal marketing devices for whole employees are inappropriate because they are different demographic aspects. To find efficient internal marketing factors, this paper analyzes empirically the determinants of employee's satisfaction to their firm, by group based demographic aspects(male and female : 2 groups, ages : 3 group, employment period : 3 groups), for a insurance claim adjuster company As a result, it is found that the psychological factor has the statically significant determinant in all the 8 groups, with biggest positive coefficient in the 7 groups. Other factors, such as the organizational factor, the individual factor and spatial factor are statically significant determinant depending on the groups differently.

This research aims to examine the spatial patterns of vacant housings and the factors determining housing vacancy in Daegu using individual-level building DB. The results of the spatial pattern analysis showed a donut shaped-spatial concentration of vacant housings in the central areas of the city. The results of logistic regression analysis revealed that not only individual building characteristics, such as building area, number of floors, and building age, but also socio-economic characteristics of community, such as urban redevelopment district, number of adjacent vacancies, recent population change, and ratio of elderly, are important factors affecting housing vacancies.

This study attempted to verify the relationship among Job Attitude, Personality and Demographic Characteristics according to Dual Commitment Type. The groups were named 'very high dual commitment group(both highly committed to the organization and union)', 'normal dual commitment group(average level of commitment to both of them)', 'resisting dual commitment group(no commitment to both of them)', 'organization commitment group(only committed to organization)', 'union commitment group(only committed to union)'. This research was analyzed by 388 Hyundai and Kia motor company members and 'very high dual commitment group' and 'organizational commitment group' showed the highest Job Satisfaction and Job Involvement. Through group segmentations considering sub-concepts could contribute to design a strategy to increase the company's competitiveness in aspects of the direction to the HR policy.

The purpose of this study was to examine how socio-demographic characteristics and delinquent behaviors affect the suicidal ideation among the Korean high school students. Using the 35,668 senior high school student cases of 2009 Korean Youth Health Risk Behavior On-line Survey data, it conducted a secondary data analysis. Frequency analysis, chi-square test and logistic regression analysis was done. Being female, living without parents, low economic status, poor academic record, technical school students, young students, poor academic record, internet addition, problem drinking, smoking cigarettes and experience of drug use significantly increased probability of their suicidal thoughts.

전 세계적인 인구증가와 도시화로 메가시티가 점차 증가하고 있으며, 2016년 기준 37개의 메가시티 중 60% 이상(23개)이 아시아 지역에 집중되어 있다. 통상, 메가시티는 불투수율이 높고 인구가 밀집되어 있어 수재해로 인한 피해규모가 크며, 인구증가에 따른 용수부족 및 수질악화로 인해 수자원 확보가 어렵다. 특히, 아시아 지역은 몬순의 영향으로 수자원의 변동성이 크며, 최근 기후시스템의 변화는 몬순의 시 공간적 변동을 증대시킬 것으로 전망된다. 즉, 아시아 몬순지역에 위치하는 메가시티는 기후변화에 더욱 취약하며 이에 따른 수자원 확보 및 수자원 관리의 어려움은 더욱 가중될 것으로 예상된다. 본 연구에서는 AR5 기후변화 시나리오를 활용하여 아시아 몬순지역 내 메가시티를 대상으로 미래기간에 대한 기온, 강수량, 유출량을 전망하고 그 특성을 분석하고자 한다. 국가별 인구 통계자료를 기반으로 아시아 몬순지역 내 존재하는 19개 메가시티를 선정하였다. 기후전망을 위해 테일러 다이어그램을 활용하여 GCMs의 몬순모의 성능을 평가하였으며, 아시아 몬순특성을 잘 반영하는 다수의 GCMs을 선정하였다. 아시아 메가시티를 평가하고자 이중선형보간기법(Bilinear method)을 적용하여 $0.5^{\circ}$ 간격의 공간해상도로 상세화하였으며, Delta method를 이용하여 편의보정을 수행하였다. GCM 모의자료의 편의를 산정하기 위해 APHRODITE의 일단위 강수자료를 이용하였으며, VIC (Variable Infiltration Capacity) 모형을 이용하여 유출량 분석을 수행하였다. 평가결과 각 메가시티의 평균기온, 강수 및 유출량이 모든 미래기간 2020s, 2050s, 2080s에서 다르게 나타났다. 해안/내륙, 경 위도 등 메가시티의 지리적 위치에 따른 변화특성 분석을 수행하였으며, 각 메가시티에 대한 여름 및 겨울철 몬순의 변화 특성을 분석하였다.

Recently, as part of the crime prevention measures that focus on spatial characteristics on the determinants of crime-causing, interest in crime prevention (CPTED) through environmental design has been increasing. This study analyzed crime vulnerabilities in Ulju-gun for the purpose of establishing a master plan for crime prevention urban design (CPTED). The 12 indicators, including demographic, socioeconomic, and physical factors, were sampled from prior studies. As a next step, statistical analysis resulted in criminal vulnerability indexes. According to the analysis, districts with a high demographic crime vulnerability indexes were concentrated on apartment complexes, while districts with high socio-economic crime vulnerability indexes have low land prices and high proportion of female population. Also, the districts with high physical crime vulnerability indexes were found to be heavily distributed commercial ones with a large number of entertainment places. However, there was a limit to generalizing the indicators of previous studies to local governments with different regional characteristics. Therefore, further studies should be carried out by establishing additional indicators considering regional characteristics in the future.
