The purpose of this study is to identify the factors affecting marriage motivation in colleger and to provide basic data for the countermeasures for decrease in marriage rate. The subjects of this study were 175 colleger from K-do. Data were collected from October 1st to October 10th, 2018 and analyzed using IBM SPSS WIN/21.0 to get frequency, percentage, average, standard deviation, t-test, ANOVA, Pearson correlation coefficient, and Multiple regression. The subjects' view on marriage was 3.35 points, view on children was 3.11 points, psycosocial maturity was 2.99, social pre-parental role recognition was 3.46, and marriage motivation was 2.81. The marriage motivation of the subjects was positively correlated with view on marriage (r=.38, p<.001), view on children (r=.50, p<.001) and psychosocial maturity (r=0.25, p=.001), and psychosocial maturity was positively correlated with social pre-parental role. The most important factor that affects the subjects' marriage motivation is their view on children (${\beta}=.407$, p<.001), followed by view on marriage (${\beta}=.329$, p<001), Gender (${\beta}=-.184$, p=.004), psychosocial maturity (${\beta}=.159$, p=009), religion (${\beta}=.126$, p=.003). The explanatory power was 52.1% (F=26.01, p<001). Therefore, a program promoting the views on children and marriage to improve marriage motivation, a customized program considering gender and religio, and further research promoting marriage motivation is needed.

This study examined the effects of non - personality behavior of supervisors on the job exhaustion and organizational effectiveness of nurses. A survey in the form of a questionnaire was completed by 250 nurses working at three general hospitals located in Seoul and Gyeonggi from September 20 to October 31, 2014. The collected data were analyzed by frequency analysis, factor analysis, correlation, and linear regression analysis using the SPSS program. The results of the analysis were as follows. First, the effects of the non-personality behavior of supervisors on the job exhaustion of nurses were statistically significant. Second, the effects of non-personality behavior of supervisors on the organizational effectiveness of nurses were statistically significant in job satisfaction, organizational commitment, and organizational citizenship behavior. Third, the effects of job exhaustion on organizational effectiveness of nurses was statistically significant for job satisfaction, job exhaustion, and organizational citizenship behavior. Because the non-personality behavior of a supervisor can have a negative effect on the exhaustion of a nurse's job and the organizational effectiveness, there should be a wide range of human resources and effective task allocations in a hospital to reduce job burnout and increase job satisfaction. In addition, it is necessary for the boss to develop desirable leadership education, appropriate modeling, and reduce their negative influence in the workplace.

Recent studies have demonstrated that word frequency, word length, neighborhood and word shape may have a role in visual word recognition. Shape information may affect word processing in different ways as Korean letter system works differently than that of English. The purpose of this study was to apply Gestalt's continuity principle to Korean alphabetic script(hangul), and to investigate the processing unit of hangul and to verify whether syllable shape affects word recognition in hangul. In experiment 1, three syllable words were utilized and two variables; 1) syllable types(horizontal syllable shape, e.g., "가". vertical syllable shape, e.g., "고") and 2) presenting direction (horizontal, vertical) were manipulated. Whereas "가" meets the criteria of Gestalt's continuity principle, "고" does not. Based on the result of lexical decision time, horizontal syllable shape type showed significant performance improvement, when compared to vertical syllable shape type, regardless of the presenting direction. In experiment 2, syllable types(horizontal syllable shape, vertical syllable shape) and the visual relationship between prime and target(identical, similar, different) were manipulated by using masked priming. There was a significant performance difference between the visual relationship of prime and target, and thus the effect of syllable shape was verified.

This study examined the empirical meaning of skylight in underground space, and for this purpose, 29 questions were drawn, consisting of technical performance, functional performance, and behavioral performance. In addition, under the assumption that the meaning of the skylight will be clearly revealed through the comparison between the underground streets with and without the skylight, three underground streets with the skylight and three underground streets without the skylight of Japan were selected as the subjects of the study. Based on the results of the survey, descriptive statistical analysis and frequency analysis were conducted, and an independent sample T-test was conducted for each analysis, and correlation analysis was conducted to derive improvement priority. As a result of the analysis, it was found that skylight had a certain effect on the sense of time and imageability inside the underground commercial space. In addition, it was analyzed that skylight exerted important function in the qualitative aspect of underground commercial space. Lastly, the improvement rankings for three underground streets without skylight were derived in the order of sign/guide map, space diversity, maintenance, rest space, and floor design.The improvement rankings for three underground streets with skylight were drawn in order of resting space, diversity of space, temperature and humidity, air, and maintenance.

This paper dealt with how realization of pauses in utterance is affected by speech style, gender, and generation. For this purpose, we analyzed the frequency and duration of pauses. Pauses were categorized into four types: pause with breath, pause with no breath, utterance medial pause, and utterance final pause. Forty-eight subjects living in Seoul were chosen from the Korean Standard Speech Database. All subjects engaged in reading and spontaneous speech, through which we could also compare the realization between the two speech styles. The results showed that utterance final pauses had longer durations than utterance medial pauses. It means that utterance final pause has a function that signals the end of an utterance to the audience. For difference between tasks, spontaneous speech had longer and more frequent pauses because of cognitive reasons. With regard to gender variables, women produced shorter and less frequent pauses. For male speakers, the duration of pauses with breath was significantly longer. Finally, for generation variable, older speakers produced more frequent pauses. In addition, the results showed several interaction effects. Male speakers produced longer pauses, but this gender effect was more prominent at the utterance final position.

When the fouling of a vessel occurs, its resistance at sea increases and there is a corresponding increase in fuel consumption. The maintenance cost of the vessel also increases because it is time-consuming to remove the fouling. To solve this problem and minimize environmental contamination of sea-water, there have been recent developments in anti-fouling paints as self-polishing copolymers that not include toxic elements such as tin. When these conventional techniques are applied to vessels, polishing is promoted during the operation whereby friction or vibration with seawater occurs. This leads to enhanced anti-fouling performance. However, when fouling is intensified such as during an anchorage, there is no flow of seawater and polishing is suppressed. This leads to a deterioration of the performance of anti-fouling. To solve these problems, we developed a system that induces vibration in a vessel during anchorage. As such, the deterioration of polishing due to insuf icient flow of seawater is inhibited. The reliability of the ultrasonic antifouling system was evaluated by calculating its repeatability. The removal efficiency of fouling of the proposed system was qualitatively evaluated using test specimens. The test revealed that the value of the coefficient of variation for the reproducibility of the frequency and amplitude was 0.2 % and 4.0 % on average. The degree of fouling of the specimens was the highest at 73.3 g in the No.5 sepcimen. Moreover, efficiency of fouling removal was 93.2 % on average compared to the specimens without the proposed system.

Mooring observations of water temperature and salinity were conducted to investigate the effects of freshwater discharge patterns on the mouth of Nakdong River from April 2017 to March 2018. More than $500-1000m^3\;s^{-1}\;d^{-1}$ of freshwater was frequently discharged into the estuary throughout the rainy season, but less than $200m^3\;s^{-1}\;d^{-1}$ was discharged through the normal season. Sluice gates of the estuarine barrage operated depending on the tide level during spring tide, but they were constantly open during neap tide. Water temperature and salinity fluctuated regularly with intermittent discharges of freshwater, whereas they were stable while freshwater discharge was continuous. Mean salinity was 29 during the study period. Salinity exceeded the mean value in the normal season and rapidly recovered after a temporary reduction. In contrast, water with salinity below the mean value prevailed in the estuary for three months over the rainy season. These results indicate that water temperature and salinity were affected by the amount of freshwater discharge, as well as the frequency of discharge on a large scale and the time over which the freshwater discharge continued.
