In this research, a small-scaled laboratory test and FEM analysis have been carried out to evaluate the feasibility of field construction with couple of recycled materials, such as in-situ soil, water-treatment sludge, and crumb rubbers. A static loading, which simulates the real traffic load, was adopted in lab test. The test was carried out, according to simulated field construction stages, such as excavation, bedding materials and pipe installation, placing and curing of controlled low strength materials, and simulated traffic loading. Couple of measuring instruments were adopted. The maximum vertical and horizontal deformations were 0.83% and 1.09%, during placing the CLSM. The measured vertical and horizontal deformations with curing time were 0.603mm and 0.676mm, respectively. The reduction effect of vertical and lateral earth pressure was relatively big. Also, FEM analysis was carried out to get the deformation, earth pressure and strain of PVC with different Controlled Low Strength Materials(CLSM) materials.

The purpose of this study is to enhance the cultural heritage value of the Juk-Bang-Ryeum (Bamboo Weir) and prove the originality through the review of historical literature. The main industry of Korean was agriculture and fishery from ancient. In the ancient, fishery instruments are not enough due to the lack of fishing technology. The Juk-Bang-Ryeum was considered as important national resources and asset. It give us many implications about the wisdom of our ancestors because of it's scientific principle of the structure. It is surely a cultural heritage to preserve in the future because it is considered as important community asset as well as more natural and environment oriented fishing method. In the literature, the origin of 'Juk-Bang-Ryeum' can be found as 'Eo-Ryang' or 'Bang-Ryeum'. The records on this terminology go back to the Corea Dynasty, but their documentary records are rare, and most of them are records of the Chosun Dynasty. In this study, we surveyed mainly the literature records about the southern coast region in the period of Chosun Dynasty. This study contributes for preserving the cultural assets of our ancestors who pursued eco-friendly fishery method, and it is also of great significance to produce objective data based on records for the registration of the World Record Heritage.

The purpose of this meta-analysis was to address two questions: (1) To what extent are types of child abuse related to psycho-social maladjustment of the abused? (2) Do relations found in this study vary by the gender, sample size, year of publication, types of publication, and respondents' age? The materials of this study were based on 14 variables obtained from 104 published and unpublished (doctoral disserations and master's theses) research papers over a span of 26 years(1990-2016). Child abuse related variables were categorized into physical abuse, emotional abuse, neglect, and abuse while psycho-social maladjustment grouped as internal (anxiety, depression, withdrawal, and anxiety/depression) and external problem behaviors(aggression, problem behavior, and delinquency). Major findings were: Medium effect size of emotional abuse, abuse, physical abuse, neglect on psycho-social maladjustment among the abused were calculated. Emotional abuse was highly related to every internal and external problem behaviors. Neglect was found to have higher effect size in external problem behaviors than internal problem behaviors. Publication types moderated the association between types of child abuse and internalization while year of publication, number of samples and publication types showed moderation effects on the relation between types of child abuse and externalization. Finding suggest that future studies on child sexual abuse and those on intervention outcome are required and use of well validated instruments are essential.

This study was conducted to investigate the factors influencing burnout of nurses in long-term care hospitals based on the expanded JD-R model (Xanthopoulou et al, 2007). Participants were 167 nurses who worked in long-term care hospitals. The instruments used in this study were the Maslach Burnout Inventory, Copenhagen Psycho-social Questionnaire version II, Connor-Davidson Resilience Scale and the instrument developed by Thomas and Ganster (1995). Data were collected from August 25 to September 6, 2018 and analyzed based on frequency, t-tests, ANOVA, Pearson's correlation, and hierarchical regression using the SPSS WIN 23.0 program. The results were as follows: Nurses' burnout in long-term care hospitals was positively correlated with job demands (r=.24, p=.002) and negatively correlated with resilience (r=-.43, p<.001) and social support (r=-.41, p<.001). Factors influencing the level of burnout were resilience (${\beta}=-.28$, p<.001), social support (${\beta}=-.20$, p=.016), and job demands (${\beta}=.17$, p=.016) ), which together explained 32.0% of the total variance in burnout. Therefore, we strongly recommend interventions that reduce job demands and enhance resilience and social support to prevent and reduce the burnout of nurses in long-term care hospitals.

The purpose of this study is to analyze motivations, benefits, and satisfactions of the college student volunteers. We carry out the pre-to-post survey with 615 college student volunteers (male 245, female 367) who have participated in the mobile education program for the elderly funded by a Telecom. The instruments consist of VFI (Volunteer Functions Inventory) developed by Clary & Snyder (1999), including 30 items for motivations, 12 items for achievements, and 5 items for satisfactions of volunteering. The items for motivations and achievements are comprised of 6 subcategories: career, value, understanding, protective, enhancement, and social. The results of this study are as follows: (1) Enhancement motivation is the highest, followed by understanding, value, career, protective, and social motivation. (2) Social benefit is the highest, followed enhancement, career, understanding, value, protective benefit. (3) The difference between motivation and benefit in social category is the largest, followed by career, enhancement, value, protective, and understanding category. While benefit is higher than motivation in all other categories, motivation is higher than benefit just in value category. (4) High motivation-high benefit, high motivation-low benefit, low motivation-high benefit, and low motivation-low benefit groups are dichotomized by the median of each motivation and benefit. In all six categories, high motivation-high benefit group shows the highest satisfaction, but low motivation-low benefit group shows the lowest. In short, benefit shows stronger correlation with satisfaction than motivation does. Finally, we suggest several implications for future research and policy of college students' volunteering based on these results.

This study explores mime elements of court Hagmu(鶴舞) in literature and what is expressed in the practice of current Hagmu and examines what has been changed while others are kept intact. The content of Hagmu is that "attracted by lotus flowers in a pond, cranes dance around and peck at them, when the blossoms open wide with a girl [dancer] inside, upon which the surprised cranes fly away." The dance consists of 4 steps: the first step is for the entrance of cranes; in the second step the cranes dance moving across jidang(池塘) and the north; in the third step the cranes are curious about the lotus calyces, yeontong(蓮筒); and the cranes withdraw in the fourth step. The literature suggests that the dancing courses on the stage are limited to the east, the west, the south, and the north. The movement is limited to naeson (內旋) only in mujin(舞進) and mutoe(舞退). Furthermore, the gaze is only allowed toward the north and jidang. Motions are limited to naejog(內足), oego (外顧), and naego(內顧). However, the mime elements of current Hagmu are attributed to the effort of translating crane's life into a realistic story. It relates the life of cranes to that of human beings and implies love in it. Finally, the court Hagmu has entered the real world out of the literature, enriched with new elements. Under the transition from literature to practice the diversity of expression is added while the elements related with court codes such as courses, movements, directions, and motions are kept intact. These limitations, however, are coupled with the sensitive 'love' and the exposure of dancing instruments intrigues audience and creates dramatic effect. In conclusion the significance of mime elements in court Hagmu is in enhancing communication with audience.

This thesis covers legal aspects of the crypto-currency exchange and the legal rights of crypto-currencies holders. Unlike financial markets in which central authorities or intermediaries determine the validity of transactions and manage records, crypto-currency markets utilize a decentralization system based on block chain technology. Such distinct characteristics distinguish crypto-currency from currency, notes, or financial instruments. Therefore, we need to check closely the legal principles that are applicable to crypto-currency. Crypto-currency users possess rights indirectly through the crypto-currency exchange. However, we should look at whether crypto-currency can be an object of ownership. This research found that legal protection for crypto-currency exchanges are limited. Domestic laws have many shortcomings to protect users' rights. This study found that users who incurred damages due to internet computation errors at exchanges require a protective system like stock markets. Therefore, studies on the legal controls and system regulations are required to protect users' rights. Also, crypto-currency information exchanges keep inside and protections for users' private information need to be further examined.

The chief mourners do their best to carry the dead and various things related to him in the departure of a funeral procession. "Sejongsillok" and "Gukjooryeui" had already written the national funeral supplies for carriage in detail in the early of Joseon period. But they were the standard book of national ceremony. The Ilbang of Gukjangdogam made the national funeral supplies for carriage in the late of Joseon; Daeyeo, Gyeonyeo, Yoyeo, Chaeyeo, Gaja etc. "Gukjangdogamuigye" explained these in detail; size, materials, made-place etc. I used "Gukjangdogamuigye" published in the late of Joseon to explain the national funeral supplies for carriage. Because Kingdom's ceremony in Joseon was representative to the country, it couldn't depend on an individual taste. King was the symbol of a nation and the star tin point of the political power at that time. So its ceremony was to show people the representative example as a national ceremony. The national funeral supplies for carriage carried the dead of King and various things related to him. Gukjangdogam managed them carefully. People thought that the mean of these things was equal to King's authority at that time. So these weren't the mere national funeral supplies for carriage, the symbolic instruments equal to King.

Objectives: The purpose of this study is to organize the research methods and results of studies related to the temperature of the warm needle for systematic utilization of warm needling technique. Methods: This study used the databases of nine (Pubmed, Science Direct, Cochrane Central, 4 Korean databases, CNKI, CiNii) to analyze temperature-related studies of the warm needle from 2000 to June 2019. Results: A total of 19 papers were included. Of these, 15 were used for mugwort, 2 for high frequency, and 1 for both mugwort and high frequency, and the other one for a ceramic heater. The maximum temperature rises as the amount of moxibustion increases. It is also affected by the density of moxa and the ignition part. There were 16 papers using stainless steel needles and 4 papers using a needle made of gold or silver to compare. In the area of the needle, the closer it is to moxibustion, the hotter it is. Compared to stainless steel needles, gold and silver needles showed almost twice the temperature. The effects of environment and radiant heat should be considered during warm needle procedures. Conclusions: There are various experimental methods such as warm needle technique materials, methods, measuring parts, measuring instruments, etc. The results were also very diverse. When setting the heating source, ignition part, size of moxibustion, etc. of warm needles, it should be implemented in a way that takes safety and validity into account. Considerations for temperature characteristics, radiant heat, etc. of warm needles will be needed when making warm needle apparatus.
