Adolescent delinquency is a substantial social problem that occurs in both offline and online domains. The current study utilized random forest algorithms to identify predictors of adolescents' online and offline delinquency. Further, we explored the applicability of classic delinquency theories (social learning, strain, social control, routine activities, and labeling theory). We used the first-grade and fourth-grade elementary school panels as well as the first-grade middle school panel (N=4,137) among the sixth wave of the nationally-representative Korean Children and Youth Panel Survey 2010 for analysis. Random forest algorithms were used instead of the conventional regression analysis to improve the predictive performance of the model and possibly consider many predictors in the model. Random forest algorithm results showed that classic delinquency theories designed to explain offline delinquency were also applicable to online delinquency. Specifically, salient predictors of online delinquency were closely related to individual factors(routine activities and labeling theory). Social factors(social control and social learning theory) were particularly important for understanding offline delinquency. General strain theory was the commonly important theoretical framework that predicted both offline and online delinquency. Findings may provide evidence for more tailored prevention and intervention strategies against offline and online adolescent delinquency.

Two kinds of Korean rice-wine (Yakju) with different process and ingredients, and Japanese rice-wine (Sake) were chosen for this study, and throughly dried and solubilized in water or cell culture medium. In vitro cytotoxicity assays of the solubilized wine solids exhibited that maximum dilution factors for inhibition of B 16BL6 mouse melanoma cell growth were 16X for herbal medicine-added rice-wine (Korean rice-wine I) and typical Korean rice-wine (Korean rice-wine II), and 8X for Japanese rice-wine. Their cytotoxic effects on HRT18 human colon adenocarcinoma cells were even lower than those on B16BL6 cells. The morphology of the tumor cells were changed by addition of the solubilized wine solids. Inhibitory effect of the rice-wine on in vivo tumor growth and metastasis were monitored after implantation of B16BL6 cells into C57BL/6 mice with daily feeding the solubilized wine solids. Compared to non-fed control groups, B16BL6 tumor growth and metastasis to lung were clearly inhibited by feeding the wine solids, in order of Korean rice-wine I > Korean rice-wine II > Japanese rice-wine. The data of in vitro cytotoxicity and the cell shape changes indicate that the inhibitory effect of tumor progression may be attributed to tumor cell differentiation or immune stimulation induced by certain components in the rice-wine, rather than direct cytotoxicity of the components.

With the liberalization of distribution services industry since 1996 as well as changes in customers' appetite to spend and consumer behaviors, new forms of distribution services have mushroomed such as superstores and SSM(Super Supermarket), online shopping, TV shopping channels. On the contrary, traditional markets have sunk into a swamp of stagnation. As this stage of stagnation of markets negatively affects tradespeople's employment, livings, and local economy, the Korean government has conducted policies to support improvement of market facilities and management since 2004. However, the government has separated facility improvement from management improvement. As of June 2008, there are 1,550 traditional markets in Korea and among these there are 388 public markets which local governments have established and managed. Public markets have possibilities to be developed as successful models of market revitalization since they can get all-expenses-paid supports for facility improvement, control of merchandise assortment, educational program for merchants. Such successful (strategic hub) markets could become the benchmark for other neighboring markets and tradespeople which could lead other successful cases. In order to produce such effects, the market should have optimized facilities, merchandise and services, co-marketing strategies with nearby markets, group purchase strategies. The hub market could play a critical role in distribution of local goods and developing high value products.

The purpose of this research is to confirm how the determinant factors for shopping mall selection (proximity, parking facility, benefits, mutual interaction effects, physical environment, surroundings) affect attractiveness (image and appraisal) of the traditional markets and revisit intention and suggest strategic methods for revitalization of the traditional markets. Results of this research are drawn from a survey of customers who visit any of the twenty-two traditional markets in the Seoul area at least twice a week. Moreover, the theory is verified through the structural equation model analysis using the SPSS win 18.0 and AMOS 18 version statistics package. From the determinant factors of visiting traditional markets, parking facility, physical environment, and the surroundings were significant in image attractiveness; benefits, mutual interaction effects, and physical environment showed significant effects on appraisal attractiveness. Additionally, image attractiveness was not significantly influential in retention proneness while appraisal attractiveness was a key factor in deciding whether or not to revisit. Therefore, improvement in image is important but appraisal aspects like product reliability that customers can personally assess, are more essential for revitalization of traditional markets.

This study was carried out to research the locations and comprehensive functions of Chinese unique Banwoldang(half-moon shaped pond) appeared at the traditional Chinese villages. Based on the research, the time of Banwoldang being introduced into Chinese traditional culture could date back to Yuan Dynasty and villages that have Banwoldang mainly distributed in the south of the Yangtze River of China where wealthy and high class have lived. Bamwoldangs were mostly built at the front of the village clan halls for the prosperity of the whole clan, The main reason of Banwoldang construction was to complete Feng Shui functions and its goal from the point of Feng Shui in Chinese ancient villages was replenishing the power of location, including increasing the probability of passing the imperial examination for villagers, multiplying riches, minimizing the fire accident and perfecting the geomantic pattern 'leaning against the hill and facing the water(背山臨水)' of villages. Other functions of Banwoldang were found as the place for the community meeting, fish farming and protection of village from enemy. In this research, the reasons of Banwoldang location and values of its various functions were found. But Banwoldang is disappearing rapidly at the Chinese modern villages because there is no interest in traditional culture. Banwoldang is one of unique elements of Chinese culture that must be preserved, so its meaning and value should be lasted well as the Chinese traditional cultures.

This study examines the modern succession, transformation and significance of enjoyment methods of classical literature (art) with a focus on the characteristics of those methods that appeared when the performances of the traditional era began to be displayed on the stage of the theaters in modern Seoul. The clues to the reasons for this type of enjoyment can be found in newspapers, magazine articles, and advertisements from the early 20th century. The emergence of stage theaters at the beginning of the modern era caused a sweeping change in the performance environment, including the fact that it was possible for all kinds of people to enjoy art beyond the existing socioeconomic hierarchies or barriers of status, that the performers were given employment through the theater, and that the audience had the tendency of the general public of an unspecified number because the audience was able to see the performances only by paying the viewing fee. The way of enjoying traditional performances also changed based on these new adaptations: the performances were sequential, show-oriented, and re-contextualized as public performances. It is significant that in the traditional era, performers and audiences had been segregated according to their status and a strict hierarchy; now, such cultural norms were breaking down in favor of a kind of equality. In addition, it was possible for the audience to experience sensory enjoyment, and theater brought about a new kind of popular consumer enjoyment of an artistic product. Of course, though, it is possible to look back and find problems related to the contemporary context, but the traditional performances, which were the main performances for the lower class, took the first place on the modern theater stage, and as a result, no one can deny that it became possible to move forward in the first phase of an era of public performance.

Traditional values refer to one's attitudes or perspectives developed by negotiating with oneself, others, society, world, nature and universe, which include thoughts on what is right, desirable, and what is dos and don'ts. The purpose of this study was to investigate values which Korean people traditionally emphasized, and their changes by epochal situation focused on the Choson Era. Also, this study intended to assist in finding values and meaning which should be passed down and manifested in contemporary society based on the study results. In this context, I select some positive values in the background of the Joseon dynasty. As traditional values or ethics in Korea destroyed and distorted going through the period of Japanese colonialism, all the existing social culture and traditional culture were denied, which resulted in vanishing common value which led community for several hundred years. The loss of common value caused community destruction and collapse, and made Korean people seek to survival, success and advancement in life as suffering from severe conflict of values. Experience of hollow state of mind caused by historical and cultural severance left distorted and degenerated values to Korea people, which made them pursue false values without realizing true meaning of traditional values. The true meaning of traditional values should be universal no matter how society changes, and could be milestone to contemporary people wandering aimlessly. Realizing and reconsidering the meaning of traditional values to found comtemporary values of Korean people by reflecting on history can produce significant results beyond age-old debate about East or West, and tradition or modernity.

The aim of this study was to investigate the effects of computer-based cognitive rehabilitation and traditional cognitive training on the working memory and executive function of patients with mild traumatic brain injury. The sample consisted of 20 patients with mild traumatic brain injury who had received rehabilitation treatment in a rehabilitation unit. The subjects were assigned to either the experimental (n = 10) or control group (n = 10). The experimental group received computer-based cognitive rehabilitation and traditional cognitive training for 60 minutes, whereas the control group received only traditional cognitive training for 60 minutes. Both the groups received their respective interventions for 60 minutes a day and 5 times per week across a period of 4 weeks. Working memory and executive function were assessed using the digit span test (forward and backward), visual memory 1 and 2 of the Motor-free Visual Perception Test-3, trail making test, and Stroop test (A and B) both before and after the intervention. The experimental group showed a significantly greater improvement in visual memory and performance on the Stroop test A than the control group. These findings suggest that computer-based cognitive rehabilitation and traditional cognitive training are more effective in promoting positive changes in the working memory and executive function of individuals with mild traumatic brain injury than traditional cognitive training.

Shadow puppetry (皮影戏) is a traditional Chinese folk art that was inscribed in 2011 as an Intangible Cultural Heritage of Humanity by UNESCO. This study focuses on analyzing the character sculptures, colors, and patterns recorded in professional books from Shanxi Province in northern China. The findings indicate that Shanxi shadow puppetry can be categorized into two types. The 'Xiaoyi' in northern Shanxi mainly features characters from the story of 'The Investiture of the Gods' (封神演义) and is characterized by the use of both intaglio and relief carving, dark colors, and a paper screen background. The 'Houma' shadow puppetry in southern Shanxi is influenced by the traditional Shanxi opera 'Jinju' (晋剧) and features four roles: Sheng (生), Dan (旦), Jing (净), and Chou (丑), using a mesh screen background. Shadow puppetry represents costumes, beliefs, lifestyles, social status, social systems, and Confucian culture from the Song, Ming, and Qing dynasties, utilizing both intaglio and relief elements, and traditional five-element colors(五行色). This study aims to understand the characteristics of the modeling art in Shanxi shadow puppetry, and to maintain the traditional craft features while adding innovative elements from animation and film, thereby promoting and preserving the traditional values of shadow puppetry culture for children and youth.

Inlet hammershock is the critical loads condition for designing the inlet duct structure of a fighter. The sudden flow reduction in engine compressor causes inlet hammershock with high pressure. The traditional method was used to combine extreme conditions (maximum speed, sea level altitude, and cold day) to analyze this compression wave inlet hammershock pressure. However, after the 90s there have been papers that presented the probabilistic approach for the inlet hammershock to achieve the appropriate design pressure. This study shows how to analyze the inlet hammershock pressure by making practical use of the Republic of Korea Air Force real flight usage data under probabilistic approach and then analyze approximately 30% decreased inlet hammershock pressure compared with the traditional valve.
