A fungus, Aspergillus sp. PS-104, with the high phosphate-solubilizing activities was isolated from Korean upland soil and formulated into a solid powder type with various additives. For the long-time preservation of conidia, some additives (Tween 80, SDS, Triton X-100, glucose, glycerol, corn oil, bio-ceramic, PEG 200, $Cu^{++}$, $Mo^{+++}$, $Fe^{++}$, $Ca^{++}$ and $Zn^{++}$) were supplemented in the rice-cooked hard medium with various concentrations (0, 0.001, 0.01, 0.1, 1.0 and 5.0%). In case of surfactants. the highest relative viability of the Aspergillus sp. PS-104 conidia was recorded nearly to 80% by the addition of 0.01 to 0.1% Tween 80, while 50% in control. The number of conidia were found to be about 100 times higher when treated at 0.01 to 0.1% Tween 80 as compared to control. Relative viability of the conidia was decreased in order of Tween 80 $\geq$ SDS > Triton X-100 during the storage at $25^{\circ}C$. As regards the organic additives, the relative viability of Aspergillus sp. PS-104 conidia was also recorded nearly to 80% by the addition of 1.0% bio-ceramic, and 5.0% glucose and sucrose during the storage at $25^{\circ}C$. In case of metal ions, the relative viability of Aspergillus sp. PS-104 conidia was decreased in order of $Cu^{2+}>Ca^{2+}>Mo^{3+}>Zn^{2+}>Fe^{2+}$ during the storage at $25^{\circ}C$.

The purpose of this study was to investigate the relationship among leisure constraints, athletic life satisfaction and self-control of student athletes at physical education high school. By using convenience sampling method of non-provability sampling, a total 217 students athletes from D and G city were selected. Of 217 copies of the questionnaire gathered, 35 were discarded owing to having excessive missing values. Thus by analysing a total of 182 surveys with structural equation modeling through SPSS 20.0 statistics program, this study found the followings. First, leisure constraints have a negative influence on athletic life satisfaction. Second, leisure constraints have a negative influence on self-control. Third, athletic life satisfaction has a positive influence on self-control.

This study examined the effects of critical thinking diposition, problem-solving ability, frustration tolerance on the college adaptation among nursing students Participants were asked to complete self-report surveys between October 1, 2017 and October 11, 2017. A total of 169 surveys were analyzed using SPSS 25.0(descriptive statistics, t-test, ANOVA, Pearson correlation coefficient, & multiple regression). Nursing major satisfaction(F=12.66, p<.001) were critical factors affecting college adaptation. Critical thinking disposition(r=.22, p<.01), frustration tolerance(r=-.46, p<.001) were significant factors affecting college adaptation for nursing students. These results indicate that programs that develop critical thinking, frustration tolerance are necessary for nursing students in order to promote college adaptation.

The purpose of this study was to determine the mediating effects of stress associated with university life and the stress response of university students' resilience towards the negative emotions of health department students. As a research method, 284 students in the health department of Gyeongsangnamdo were surveyed. Data were analyzed in terms of frequency, correlation and regression using SPSS 22.0 program. The results of the study were as follows. The mean score of resilience towards negative emotions among students in the health department was 4.49, while stress associated with university life was 2.74. As a result of the correlation analysis among resilience towards negative emotion, stress response and stress associated with university life, the negative emotion was found to have a negative correlation with the stress associated with university life and the stress response. Resilience towards negative emotions was found to reduce the stress associated with university life by mitigating the stress response. Therefore, in this study, resilience appears to affect the stress associated with university life and the students' response to it. Therefore, for students in the health department who are exposed to stress associated with university life, the resilience towards negative emotions may be a way of alleviating the stress response.

The purpose of this study is to identify the factors affecting the adaptation, Self-esteem and self-control of college students to smart addiction. We surveyed 380 university students in Gwangju area. Data were analyzed by t-test, one-way ANOVA, Pearson correlation analysis. Smart phone addiction according to general characteristics showed the lowest in fourth grade and high in health-related majors. Smart phone usage time was the lowest in less than 3 hours due to the actual usage of smart phone. School life adaptation, self-esteem, and self-control according to general characteristics were higher in satisfaction with college life and majors. The most influential factors on the addiction of smart phone were perceived smart phone addiction, and the self-esteem and self-control were more likely to be addicted to smart phone. Therefore, it is necessary to develop education and programs to enhance self-esteem and self-control of college students and to find ways to prevent smart phone addiction.

Various diagnostic methods, such as electric pulp test, cold test, test cavity etc., have been used to determine the pulp vitality. At least two or more methods should be used with supplemental information to diagnose each case because using one method doesn't provide sufficient accuracy. These conventional methods have depended on nervous responses, but Laser Doppler Flowmeter determines the pulp vitality by measuring pulpal blood flow. In this case, we tested the vitality of the traumatized teeth with incomplete root apices and autotransplanted teeth with conventional methods and Laser Doppler Flowmeter. Conventional methods, such as electric pulp test and cold test can produce various responses according to the development state of the pulpal nerve and the sensory threshold of the patient. But, Laser Doppler Flowmeter has a lower false response rate than any other pulp vitality test methods and it can determine the vitality somewhat earlier than the other method.
