This study aims to grasp the influence of a college student's academic emotions and the ability of interpersonal relations according to gender on the SNS addiction tendency. Data were collected through a self-reported structured questionnaire from 130 college students using convenient sampling methods from September 1 to October 31, 2015. The research result showed that in the case of male college students, only the ability of interpersonal relations (${\beta}=-.41$, p=.009) was understood as a variable with an influence on the SNS addiction tendency, having approximately 16% power of explanation (F=2.26, p=.049) after controlling for age, daily average duration of using SNS, subjectively-perceived level of dependence on SNS, and one's own level of using SNS. In the case of female college students, it was understood that the daily average duration of using SNS (${\beta}=.42$, p<.001) and positive academic emotions(${\beta}=.27$, p=.010) were variables having an influence on the SNS addiction tendency, having approximately 28% power of explanation (F=5.19, p<.001). Accordingly, to solve the psycho-social health problems related to male and female students' SNS addiction based on this research, it might be helpful for planning a program by taking into account the differences between the related variables according to gender.

The purpose this study was to explore the return-to-work experience of nurses after receiving cancer treatment. The participants of this research were 6 registered nurses who were working when they were diagnosed with cancer. Data were collected by individual in-depth interviews from January 5 to January 29, 2016 and analyzed using phenomenological methodology by Colaizzi(1978). The study results revealed that the return-to-work experiences of nurses after receiving cancer treatment may be categorized as 'Enduring hardly', 'Living a balance in my turning point', 'Reborn' and may be identified with 9 theme clusters and 27 themes. Their experience of returning to work as a nurse after cancer treatment consisted of expressing difficulty in handling both work and treatment. Despite that, they came to live a more mature life after their disease and came to affirm their existence through their work. Thus, an improved working environment to manage both work and treatment and continual support and assistance from society is deemed necessary.

The slime formed at the bottom of the borehole causes the excessive displacement and loss of the bearing capacity of the drilled shaft. In this study, the slime meter is developed for the evaluation of the slime based on the electrical properties of the fluid and the slime in the borehole. The slime meter is composed of a probe instrumented with electrodes and temperature sensor and a frame with rotary encoder, so that the slime meter profiles the electrical resistivity compensated with temperature effect along the depth. For the application of the slime meter, three field tests are conducted at a borehole with a diameter of 3 m and a depth of 46.9 m with different testing time and locations. For all the tests, the experimental results show that while electrical resistivities are constantly measured in the fluid, the electrical resistivities sharply increase at the surface of the slime. Therefore, the slime thicknesses are estimated by the differences in the depths of the slime surface and the ground excavation. The experimental results obtained at the same testing point with different testing time show that the estimated thickness of the slime increases by the elapsed time. Also, the estimated slime at the side of the borehole is thicker than that at the center of the borehole. As the slime meter estimates the slime in the borehole by measuring the electrical resistivity with simple equipment, the slime meter may be effectively used for the evaluation of the slime formed at the bottom of the borehole.

This study aims to investigate the relationship between positive psychological capital and entrepreneurial intention among middle-aged and elderly individuals who are interested in starting their own business by focusing on the mediating effect of risk sensitivity and the moderating effect of asset status. To accomplish the study's objective, a questionnaire was administered to approximately 250 middle-aged and elderly people working in Seoul from December 1 to December 31, 2019. Collected data were analyzed using SPSS 26.0. Specifically, frequency analysis and descriptive statistics were conducted, and reliability of the constructs was assessed. Factor analysis was used to measure the goodness of fit of the model developed. Finally, a structural equation model was established, and analysis was conducted on the test of the hypotheses about the mediating, moderating, and adjusting effects using the AMOS statistical package. The results revealed that positive psychological capital had a positive impact on risk sensitivity, and the path analysis of self-efficacy and entrepreneurial intention as well as resilience and entrepreneurial intention showed results of 0.042 and 0.026, respectively, supporting mediating effects. In the causal relationship between positive psychological capital and entrepreneurial intention, asset status acted as a moderator given that the chi square difference between the models was 7.096. Thus, the findings provide implications for comprehensive training programs to boost positive psychological capital and asset status in middle-aged and elderly individuals who are preparing to establish their own business. Further studies are needed to cover broader geographic areas and compare/analyze other variables associated with business startups.

Geosynthetics are widely used in different ways such as reinforcement of structures in road, railway, harbor and dam engineering, drainage, separation and erosion prevention. They are especially applied to reinforced retaining wall and slope or ground reinforcement. Recently, geosynthetics reinforced pile supported (GRPS) embankment was developed to improve stability and construability of embankments in railway engineering. Extension strains are usually measured by strain gauges adhered to geosynthetics to evaluate the stability of geosynthetics. However, the measurements are influenced by manufacturing method and stiffness of geosynthetics and also adherence of strain gauge. In this study, wide-width tensile strength tests were performed on three types of geosynthetics including geogrid, woven geotextile and non-woven geotextile. During the test, strains of geosynthetics were measured by both video extensometer and strain gauges adhered to the geosynthetics and the measured results were compared. Results show that the measured results by strain gauges have high reliability in case of large stiffness geosythetics like geogrid and woven geotextile, whereas they have very low reliability for small stiffness geosythetics like non-woven geotextile.

This study was conducted to figure out characteristics of the children of problematic drinkers by reviewing the studies on those children reported in nursing studies in Korea and incorporating the results. The research method was integrated literature review, and for the study, eleven articles were selected by searching with key words such as 'problematic drinking', 'alcoholic', 'alcohol dependence', 'children', and 'nursing' in three research databases, spanning between 2000 and 2014. The research results are as follows: For the domestic nursing studies on the children of problematic drinkers, there were many descriptive research using survey method, requiring introduction of various research methods in order to know characteristics and lives of the children of problematic drinkers in depth. For main characteristics of the children of problematic drinkers, they have lower ability to cope with, many of them suffer from psychological and mental health problems, are very sensitive in interpersonal relationships with higher hostility. In addition, it is reported that the children of problematic drinkers are likely to have more problematic drinking, show higher depression and lower emotional perception and expression, social support, and social competence. Based on the results of this study, considering the fact that there are extremely few studies on the children of problematic drinkers, it requires more active studies and researches in nursing. Through the study with accurate results, it will contribute to nurses' capability in both clinical settings and local community as a guideline.

Elastic behavior of the railway roadbed which supports the repeating dynamic loads of the train is mainly affected by the shear modulus of the upper roadbed. Therefore, shear wave velocity estimation of the uniformly compacted roadbed can be used to estimate the elastic behavior of the railway roadbed. The objective of this study is to suggest the relationship between the dynamic cone penetration index (DCPI) and the shear wave velocity ($V_s$) of the upper roadbed in order to estimate the shear wave velocity by using the dynamic cone penetration test (DCPT). To ensure the reliability of the relationship, the dynamic cone penetration test and the measurement of the shear wave velocity are conducted on the constructed upper roadbed. As a method for measurement of the shear wave velocity, cross hole is used and then the dynamic cone penetration test is performed at a center point between the source and the receiver of the cross hole. As a result of the correlation of the dynamic cone penetration index and the shear wave velocity at the same depths, the shear wave velocity is estimated as a form of involution of the dynamic cone penetration index with a determinant coefficient above 0.8. The result of this study can be used to estimate both the shear wave velocity and the strength of the railway roadbed using the dynamic cone penetrometer.

As buildings increase in height, lifting plans are becoming increasingly important on construction sites. As a critical piece of load-lifting equipment, the tower crane deserves a well thought-out stability review, since it has a significant impact and is very vulnerable to structural safety disaster. To ensure the structural stability of a tower crane, its lateral support or pile supported foundation designs must include consideration for stability, and pile foundation must be used if site conditions prevent soil from providing the required bearing capacity, or prevent the foundation from being increased to the required extent. Pile supported foundation design requires thorough and systematic review, as more stability parameters need to be considered than with an independent foundation. This paper intends to develop an optimal design algorithm that can minimize associated costs while ensuring the fundamental stability of pile supported foundation design, limiting the scope of research to fixed-type trolley tower cranes using pile supported foundations. The findings herein on pile foundation stability review parameters, process and optimal design are expected to improve the operational efficiency of staff concerned, and reduce the time and efforts required for pile foundation design.
