Using data sets from the Korean Labour and Income Panel Study (KLIPS) for the period 2003-2015, this study shows that wages of nonunion workers are positively related to the percentage of unionized workers in the same geographic region. A 10 percentage point increase in a region's union density is associated with a 4.9 percent increase in the region's average wage of nonunion workers. It is also shown that this positive spillover effect is observed for various subgroups of nonunion workers, including women, youth, low-educated workers, small firm employees, and those employed under nonstandard work arrangements. In contrast, the average wage of union workers is found to respond insignificantly to changes in a region's union density.

In this study, we developed the multicultural program that could strengthen capabilities of the local childcare community and analyzed the satisfaction and effects of the program. The multicultural childcare community programs are designed for taking into account the conditions of effective contact between social groups. Five programs for multicultural childcare community are performed during the period (August from July 2015), and there were 196 members of local community involved in that programs. Local multicultural community program indicated a high satisfaction and we were able to lead on building their self-esteem and social engagement of multicultural parents through that program. Furthermore, we can confirm the needs of the program for local multicultural childcare community have continued. It is significant that this study provides basic data for the multicultural childcare community program to make a contribution to another local multicultural community.

This paper describes to experiments on the estimation of tourist images in Busan. Preliminary tasks were performed to find out the condition of tourism souvenir and products proper to ocean city with situation in Busan. This survey analyzed by factor analysis taken in local residents, foreigners and other city. Result of factor analysis shows that the local residents and others think of Busan as similar image both. Outsider recognized Busan to tourist attractions of seaside environment and tourist facilities, and have good image of sightseeing and shopping in city. The local people remind Busan as progressive, feels sweet, activity, friendly image beside that foreign tourist remind as clean, modern, abundant, and others think as stable, changing, novelty, friendly. To abstract 8 factors among the images, take out of relevance to condition of tourist and image factors. Important factors for development of tourist industry in Busan are a feeling safe, clean, novelty in priority. And find way that enhancing image to abundant, friendly, activity were proper to tourist industry.

면적강우량은 수치예보모형(NWP; Numerical Weather Prediction)이나 분포형 강우유출모형 등에서 가장 중요한 입력변수이다. 기상레이더는 광범위한 시공간분해능을 지닌 강우관측기기로서 널리 이용되고 있다. 레이더 반사도 자료를 이용한 강우추정에 대한 연구는 Z-R 관계식을 이용한 방법, 지상우량계와 연계한 통계적인 방법 등 다양하게 전개되어 왔다. 일반적으로 많이 사용되는 Marshall and Palmer(1948)가 제시한 Z-R 관계식은 층운형 강우에는 비교적 타당한 결과를 얻을 수 있지만 적운형 강우에 대해서는 그러하지 못하다. 또한 지상우량계와 연계한 방법은 주로 geostatistic 기법(ordinary kriging, co-kringing, kriging with external drift 등)을 사용하지만, 배리오그램(variogram)을 작성해야 되는 등 계산절차가 복잡하고 시간이 많이 걸려 실무에 적용하여 실시간으로 강우정보를 제공하기에는 다소 무리가 따른다. 따라서 본 연구에서는 지상우량계로 관측된 강우량과 레이더 추정강우 사이의 보정계수를 이용한 실시간 Z-R 관계식으로 레이더강우를 추정할 경우 발생될 수 있는 문제점들을 제시하고 개선방안을 모색하여 보다 정확한 레이더 강우를 추정하고자 하였다. 연구 대상지역은 부산레이더 반경 240km 이내 지역이며, 강우사상으로는 2002년 8월 31일 (태풍 "루사")의 레이더 반사도 자료를 이용하였다. 또한, 지상관측 강우량자료는 AWS(Auto Weathering System) 중에서 부산레이더 관측범위 내에 존재하는 68곳의 1시간 누적강우량을 사용하였다. 연구 결과, 기존의 실시간 Z-R 관계식을 이용할 경우 단순히 지상우량계와 레이더 강우 사이의 보정계수를 사용하면서 물리적인 범위를 벗어나 과대 추정되는 결과를 발생시켰다. 본 연구에서는 이렇게 과대 추정되는 부분을 제한함으로써 보다 현실적이고 타당한 면적강우량을 산정할 수 있었다.

The purpose of this study was to present an alternative to improve the complex structure of Gyeonggi port governance. Based on previous research, advanced port operation, timely development of port, port safety management, and growth with the region were selected as the main roles of port governance. In addition, the importance of each role was analyzed by selecting the government-led port authority and government and local joint port authority as alternatives. As a result of the analysis, it was found that the establishment of the government-led port authority was reasonable in terms of advanced port operation, timely port development, and port safety management. On the other hand, local joint port authority is reasonable in terms of growth with the region. The implication of this study is that it is necessary to simplify port governance in Gyeonggi Privince and establish the government-led port authority in which Participation of local governments is required for linking regional administration and urban development plans.

The introduction of invasive marine species of living things into new environments by ship's ballast water, attached to ships' hulls and via other vectors has been identified as one of the four greatest threats to the world's oceans by Global Environment Facility(GEF). Making use of the new technology of alpha-AL$_2$O$_3$ dielectric barrier layer, the strong electric-field gas discharge was introduced and obtained between micro-gap electrodes at high pressure (∼105㎩) of $O_2$ in air and $H_2O$ in seawater. The mixed air with $H_2O$ could be ionized and dissociated into large numbers of activated particles of OH, $O_2$＋, O(1D), HO$_2$ and so on, and then dissolved into the ballast water to form dissolved hydroxyl radical with the concentration of ∼20mg/L. Therefore, the invasive marine species was treated effectively through the hydroxyl radical dissolved pipeline of ballast water by strong electric -field discharge.

The studies on the rural housing have focused on folk housing, but this study focuses on the contemporary rural housing with special reference to the roof types/materials and the outer wall materials. The research area of this study is the fourteen rural settlements in Jeju Island. The hip roof type, the hip/flat roof type, the simple-flat roof type, the gable roof type, and the eyebrow-and-flat roof type are the most frequent roof types. Among the roof materials, the precoated steel plate, the artificial slate, the cement, the cement/roof tile, and the cement/artificial slate are the most frequent materials. The cement holds more than a half of the outer wall materials, and the cement/basalt rock, the tile/cement, the tile, and the diverse siding are the next frequent outer wall materials. The comparison of the rural housing reveals that there are some clear differences between Jeju Island and Gyeongnam Province in terms of the roof types and the outer wall materials.

The sea traffic volume in Southwest sea including Wando area have increased every year. However the improvement of the facilities for convenience and safety in port and sea was not enough to meet the increasing demand of traffic and passengers' need. This study dealt with the situations and status of passenger ship traffic system in Wando area. In addition to, questionnaire survey of passenger ship user in Wando area was carried out in order to research the improvement of marine traffic system. On the basis of the result, navigation risks in the area was analysed. The institutional system such as passenger ship fare, enhanced traffic system that can improve marine traffic environment in the area were suggested and examined. The urgent issue was the scattered fishing ground near fairway which makes narrow passage and can cause risky passeger ship's navigation. In the side of passeger ship's operation, the wage of cargo handling was relatively expensive that needed to be improved.

Objective : The purpose of this study was to establish the concurrent validity of the Korean Occupational Balance Assessment(OBA) tool. Methods : This study was conducted on 1016 people from October 1 to October 25, 2019. Data collection was performed using OBA and Occupational Balance Questionnaire11(OBQ11). The data were analyzed by descriptive statistics, Pearson correlation. Results : There was a significant correlation between the scores of the three areas of OBA and the total score of OBQ11(p<.01). All three areas were analyzed with positive correlations. The time use area (r = .554) and occupation frequency area (r = .574) were found to be correlated. Most of the sub-factors in the occupation characteristics area (importance r = .582, goal achievement r = .633, enjoyment r = .649, health r = .650) were analyzed with high correlation. Conclusion : OBA has proven to be a valid and reliable assessment tool for measuring occupational balance. Further research needs to provide guideline on occupational balance for usefulness in clinical area.
