Isolation and identification, prevalence and density of Setaria microfilariae(mf) were investigated in the blood of 406 cattle slaughtered at the abatoirs in Yungnam province from February 1999 to March 2000. Nine ml of blood from the jugular vein was collected in a test tube including EDTA respectively. The blood was mixed(10 : 1) with 0.2% Saponin in saline solution. This mixture was diluted again(1 : 10) with saline solution and stirred. This diluted mixture was filtered using Millipore membrane filter with a pore size of $3.0{\mu}m$. Mf were recovered from the membrane in saline solution. Mf isolated were identified as Setaria digitata on the basis of morphologic characteristics. Infection rate of the mf of total 406 cattle was revealed as 6.40%. Seasonal prevalences of the mf were presented 9.46%(7/74) in Autumn, 7.05%(11/156) in Summer, 4.65%(4/86) in Winter and 4.44%(4/90) in Spring respectively. Average density of the mf of every 9ml blood in 26 positive cattle was revealed as 170(2-641) worms. Seasonal densities of the mf of 9ml blood were presented average 361(160-641) worms in Autumn, 205(16-620) worms in Summer, 108(6-204) worms in Spring, 6(2-11) worms in Winter respectively.

Purpose: This study was designed to assess the level of super-leadership and self-leadership, identify correlations among variables and identify the factors influencing organizational commitment of clinical nurses. Methods: Participants were 217 nurses working in four hospitals located in Seoul and Gyeonggi Province. Data were analyzed using descriptive statistics, independent t-test, one way ANOVA, Scheffe. test, Pearson Correlation, and Multiple Regression. Results: The most influential factor for organizational commitment was super-leadership (${\beta}=.28$, p<.001), followed by education ${\beta}=.16$, p=.007), the number of unit nurses (${\beta}=.18$, p=.003), self-leadership (${\beta}=.17$, p=.008), and the number of patients being under 10 (${\beta}=.12$, p=.046). These factors accounted for 23% of the variance in organizational commitment (F=13.46, p<.001). Conclusion: The results of this study suggest a need for strategies to improve organizational commitment of nurses by enhancing nurse' self-leadership through nursing managers' super-leadership.

Purpose: The purpose of this study was to investigate the effects of appearance stress and appearance management behavior on job-seeking stress among male university students. Methods: The participants of this cross-sectional and descriptive study were 158 male students attending a university in K Province who completed a self-report structured questionnaire. The survey period was from September 19th to November 9th, 2017. Data were analyzed using descriptive statistics, independent t-test, one-way ANOVA, correlation and multiple linear regression analyses with the SPSS statistics 23 program. Results: Job-seeking stress showed significant differences according to BMI (F=2.55, p=.042) and pocket money (F=3.08, p=.049). The results of the regression analysis showed that grade (${\beta}=8.93$, p=.008), pocket money (${\beta}=-5.11$, p=.029), appearance stress (${\beta}=.52$, p<.001), and appearance management behavior (${\beta}=.25$, p=.001) were significant factors affecting jog search stress. Conclusion: The findings of this study suggest that variables such as grade, pocket money, appearance stress, and appearance management behavior significantly explain job-seeking stress among male students in college. Therefore, it is necessary to develop a program to reduce job-seeking stress for senior male students who are preparing for employment before graduation. In addition, when organizing a program to reduce job-seeking for male university students, it is necessary to help them have a more positive evaluation of their appearance and pursue proper appearance management behaviors.

Tripitaka Koreana in Haein Temple, Hapcheon Province is the most historical and largest heritage in this country, however the species of their blocks have yet been unknown. A nondestructive test method is necessary to investigate their species. The oven-dry density of wood was measured by inversely using the principle of high frequency moisture meter. The oven-dry densities of more than 100 domestic species of specimens estimated by measurement method and high frequency moisture meter were compared and following conclusions were obtained. There was highly close correlation between the oven-dry density estimated by measurement method and the oven-dry density estimated by high frequency moisture meter. The densities of Tripitaka Koreana that was a global cultural heritage could be correctly estimated by using high frequency moisture meter and the equilibrium moisture content under which Tripitaka Koreana equilibrated, thus, it was expected to provide the key to species identification.

During 2015-2017, we surveyed the incidence of viral infections of tomato and paprika growing in greenhouses in Cherwon province, Korea. In 2015 and 2016, we collected leaves and fruits from tomato and paprika plants growing in greenhouses. We detected viruses in the samples collected using specific primer sets for Broad bean wilt virus 2 (BBWV2), Cucumber mosaic virus (CMV), Pepper mild mottle virus (PMMoV), Pepper mottle mosaic virus (PepMoV), and Tomato spotted wilt virus (TSWV). We detected PMMoV, CMV, and TSWV in the samples, and CMV and TSWV were the most prevalent. For the prevention of future viral diseases, we then surveyed the routes of infection by these viruses in tomato and paprika plants growing in greenhouses in Cherwon province in 2017. Leaf and fruit samples were collected from seedlings and crops two and four months after transplanting into greenhouses. As a result, we found that TSWV was transferred from seedlings to plants, and outbreaks of the virus occurred at the early stage of cultivation. On the other hand, we found that CMV was a virus indigenous to the soil of some towns in Cherwon province, and thus outbreaks of this virus occurred at the middle stage of cultivation.

This study histologically describes the gonadal development and reproductive cycle of the abalone, Haliotis discus discus inhabiting Jeju Island of Korea. Gonads displayed histologically definitive seasonal changes. The gonad index (GI) of both females and males was the highest (3.2 and 3.3) in September and was the lowest (1.7 and 1.4) in January and February. Egg diameter increase from early stage in March and reach about $180{\mu}m$ to ripe stage in August. The condition index (CI) was highest in July and lowest in May. The pattern of changes in the GI, egg diameter and CI were similar to the pattern of seasonal changes in gonadal tissues. The female ratio (F/F + M) was 59% (n = 182:127). The reproductive cycle was divided into an inactive stage (January-February), early active stage (March-April), late active stage (May-July), ripe stage (August-October) and spent and degenerative stage (November-January). The main spawning period of H. discus discus was August to October at Jeju Island in 2014.
