Franchise restaurants in Korea are making efforts to improve service quality by developing and following service quality manuals to provide uniform services. This study was conducted to verify the fact that such efforts to provide uniform services would increase customer satisfaction and influence customers' decision to revisit. After setting up research models and hypotheses, the survey was conducted for 30 days from April 1 to 30, 2008 and a total of 279 copies were analyzed. The result of this study includes three findings. First, among the independent variables pertaining to the influence of uniform service quality on customer satisfaction, service uniformity, brand uniformity, and space arrangement uniformity were most influential. Also, among the brand image variables, service uniformity was most influential on customer satisfaction. Second, it was found that uniform service quality had positive influence on customers' behavioral intentions and that menu was the most influential factor. Third, it was found that higher customer satisfaction had greater influence on customers' behavioral intentions.

The bonded orthodontic retainer constructed from composite and multistrand orthodontic wire provides an esthetic and efficient system for maintained retention. This study was designed to measure shear bond strength of bonded retainers and to suggest a optimal combination of a multistrand wire and bonding method used when bonded retainer was fabricated. 160 sound maxillary and mandibular premolars were used for 80 test samples. After Uniformizing bonding area, length of wire, and thickness of composite, multistrand wire was bonded to fabricated a bonded retainer by direct or indirect bonding method. Shear bond strength and extension length of each sample were measured by a universal testing machine. The results of this study were as follows : 1. In vitro shear bond testing found 6-stranded, 0.0155 inch wires to have the largest shear bond strength and 3-stranded, 0.0195 inch wires to have the least shear bond strength. But, These difference was not statistically significant(p<0.05). 2. In vitro extension testing found 3-stranded, 0.0155 inch wires to have the largest extension length and 3-stranded, 0.0195 inch wires to have the least extension length(p<0.05). The larger diameter wire was used, the larger extension length was shown. But, the strand of wire is not related to the extension length of wire. 3. In comparison with direct bonding method, larger shear bond strength and extension length was shown in indirect bonding method(p<0.05).

The objective of this study was to analyse the residual stress in Larix kaempferi board during and after kiln-drying. The boards were primarily intended for using as laminar of cross laminated timber (CLT). In this study, the equivalence of moisture content by equalizing treatment was proved and reduction of residual stress by conditioning treatment was quantified. Prong test and slice test were carried out to analyse the residual stress in wood during drying. Transverse casehardening was measured immediately after making prong sample. Residual stress of four parts in wood from surface to center was analyzed quantitatively based on elastic deformation after just cutting slices from board. Tensile stress and compressive stress on the surface of board during drying did not exceed 2.2 MPa when boards were dried by kiln-drying schedule of T10-C4 and T12-D5. Because the tensile strength and compressive strength of transverse direction of Larix kaempferi lumber are 2.65 MPa and 4.60 MPa, application of more severe drying schedule can be recommended. Cup and twist were reduced by about 40% by equalizing and conditioning treatments after drying.

국내 절토비탈면은 이상 기후 및 건설공사의 증대로 인해 증가하고 있는 추세이며 장마철 및 태풍으로 인해 비탈면의 붕괴로 많은 인명 및 재산피해가 발생되고 있는 실정이다. 국내에서 사용되고 있는 기존의 비탈면의 설계기준은 암반의 불연속면에 대한 조사를 실시하고는 있지만 주로 암반의 굴착난이도를 토층, 리핑암, 발파암으로 구분하여 각각의 비탈면 절취경사를 결정하여 사용하는 방법을 사용하였으며 이러한 기준은 단순히 암석의 강도를 기준으로 설정되어 있으므로 암석의 공학적 특성 즉, 암반내 불연속면 방향성, 연속성, 충진물질, 마찰각, 풍화속도 등의 영향으로 공용후 비탈면 구배의 재조정 및 보강이 빈번하다. 국내외 절토비탈면의 설계기준은 각 기관별로 산재되어 있었으며 비탈면에 대한 설계 및 시공 등에 관한 기준은 도로와 철도 설계기준에 일부 반영되어 있을 뿐 항만, 댐, 택지조성 등 기타 시설 설계기준에는 비탈면에 대한 기준이 마련되어 있지 않아 표준적인 비탈면 설계기준 및 유지관리지침이 등이 필요하였다. 이러한 문제점을 보완하기 위해 2004년부터 2006까지 한국시설안전공단, 한국도로공사, 대한주택공사가 협동으로 연구한 건설공사 비탈면 설계 시공 및 유지관리에 관한 연구의 결과로 2006년도에 "건설공사 비탈면 설계기준"이 수립되었다. 이 설계기준은 건설공사에서의 기존 상이한 기준들을 정리하고 동일화하는 작업을 수행하였으며 지반의 조사에서부터 대책공까지를 막나하여 정리하였다. 그러나 최근에 급격한 기후변화로 인한 비탈면붕괴 빈번함에 따라 과거 적용되어 왔던 이들 기준을 적용하는 경우, 특히 상부 토층 및 풍화암 구간에서 많은 설계안전율을 만족하지 못해 많은 보강을 수반해야 하는 문제가 발생되고 있어 그 원인에 대한 분석을 수행하고자 하였다. 2006년도 정리된 기준은 과거에 적용하여 온 유기시의 안전율 조건을 Fs > 1.1~1.2을 적용하였던 것을 Fs > 1.2로 통일하였으며 지하수위 조건은 지표면에 위치하도록 하였다. 지하수위 조건은 풍화암 및 토층의 경우, 과거 지표면에 -3m를 적용한 시기가 있었으나 지표면에 지하수위를 적용하는 것이 일반적인 해석방법이다. 이러한 결과의 원인을 검토해 보면 다음과 같다. 첫째, 풍화암 및 토층에 적용되어 온 지반강도 정수가 과거 적용한 값보다 최근에는 작아지는 경향을 보이고 있다. 둘째, 지하수위 적용문제로 현재 지표면에 지하수위를 두어 안전율을 감소시키는 문제로 이는 최근 들어 많은 연구기관에서 강우시 간극수압의 증가에 대한 연구가 활발하게 진행되고 있다. 그러나 침투수 해석은 현행 기준에도 강우의 침투를 고려한 해석을 실시하는 경우 FS > 1.3 적용하는 것으로 되어 있으나 대부분의 해석에서는 적용이 되지 못하고 있는 실정이다. 셋째, 안전율이 과거에 주로 적용된 Fs > 1.1에서 Fs > 1.2로 상향 조정되어 우기시의 설계안전율 만족시키지 못하는 문제이다. 그러므로 이러한 문제점을 개선하기 위한 검토가 필요하며 장기적으로 이에 대한 합리적인 기준을 개정하는 작업이 추후에 수행되어야 할 것으로 판단된다.

The purpose of this study is to analyze the 'identity' found in constructional characteristics of Geumgok Hongneung, the first imperial tomb of Korean empire. In terms of "sameness", which states for internal self-cognition among ambivalent situations while consisting identity, Hongneung inherited the prosperity of the Chosun dynasty, possessed 'sustainability' related to Cheongryangri Hongneung of Empress Myeongseong, as well as revealed various 'identitification' of situations in order to expose self-esteem as emperor and imperial nations. On the other hand, in terms of "individuality" as an external self-cognition, the opposite phase of sameness, Hongneung is a mixture of the will of Emperor Gojong and Japanese intervention hence formed 5th styles of royal tombs through 'peculiarity' which distinguishes it from the original tradition. In addition, the value of Hongneung is that it actually reflects the confusing and difficult times of the old ages, and it also involves 'excellence' as the place of the according a state funeral of Emperor Gojong and provoking March First Independence Movement. Thus, Geumgok Hongneung is a recorded landscape that clearly reflects the times of royal tombs of the Chosun dynasty, the world cultural heritage, and also the historic landscape showing extraordinary landscape of unique characteristics, 'Hwangjereung'.

The systematic research on the Joseon history under Japanese imperialism in the 1920s, including that of the Joseon History Compilation Committee, was one of the stratagems that Japan employed to perpetuate the colonization of Joseon. The 'renovation of national traits', one of the three cultural measures taken by Japanese imperialism after the 1919 Independence Movement, was an attempt to degrade Joseon's nationality as extraneous, dependent, factional, and uncivilized. Against this, Koreans tried to create their own tradition that could prove Joseon's uniqueness and independence. The purpose of their study on ancient history, which became animated in the 1920s, was not to escape from the reality of Joseon into the idealized past, but to construct the history of Korean people anew. In this context, Dangun could refer to cultural identity as the communal origin of the nation, and this invented identity could lead to the healing of the injured subject. An Hwak's attempt was part of this efforts to call out myth as history. He suggests that Joseon's national traits are superior even to the Western civilization in several ways, and his vast plan to set up Joseon's cultural uniqueness and identity as history of universal civilization bore fruit in the History of Joseon Civilization. With cultural research for figuring out Joseon's national peculiarity and identity and historiography for revealing Joseon's national potential, he makes it possible for people to imagine various agents in the Joseon's past as belonging to a single nation with an identical history. Through his study on Joseon, he fought back the Japanese colonial view of history and tried to exalt national consciousness. Asserting independent and rational individuals as agency of civilization and culture though firm in the national perspective, he eventually went a way quite different from that of Japanese history of culture.

This study aimed to examine the influence of a weight loss reality show watching on viewers' psychology and viewing effects by explicitly focusing on the Chinese TV show, Wow! Nice Figure (2019). Chinese women who had experience viewing Chinese TV show, Wow! Nice Figure and an experience of weight loss were the subject of the current study. The data collected from a total of 201 Chinese women were examined. Six variables; age, monthly income, occupation, education, BMI(Body Mass Index), and weight loss experience were included as control variables, and the data were analyzed with the use of SPSS 20.0. The results revealed that both simple and social viewing had been found to impact viewers' psychological attitudes positively. However, it was supported that simple and social viewing does not directly affect viewing satisfaction. Furthermore, the mediated effect of psychological variables within the relationship between simple viewing and viewing satisfaction and the relationship between social viewing and viewing satisfaction was investigated. From this study's results, the enhanced understanding of the impact of simple viewing, social viewing, and viewer's psychology on viewing satisfaction could be discussed.

The purpose of this study was to find out whether or not the disabled students' assistance could be interpreted as a serious leisure. t is academically worth because this study reviewed if college students voluntarism could be considered a leisure and provided fundamental information about the interaction between the volunteered and the disabled. Voluntarism in the college level, in general, is spontaneous. The volunteered are expected to experience a psychological well-being, and their participation in voluntary activity helps them have a chance to develop socially, emotionally, and psychologically. In addition, as Stebbins(2001) claims, a serious leisure could be kept with one's enjoyment and play a role of leisure. Therefore, this study interviewed 6 college students who played a role of a spontaneous assistant. As results, 103 conceptual terms and 13 sub-categories and 5 higher categories were come out. The volunteered had stress at the early stage and experienced a state of being identified with the disabled. They, however, had an opportunity to foster expertise for volunteering, which contributes to their increased enjoyment and consistent volunteering thereafter. Some, even quitted in the middle, showed effort to find an appropriate substitute. It was revealed through this study that college students' assistance to the disabled has attributes for a serious leisure.

Background : The transforming growth $factor-{\beta}1$ ($TGF-{\beta}1$) plays a key role in lung fibrosis. However, the molecular mechanisms involved in $TGF-{\beta}1$-induced lung fibrosis are unclear. $TGF-{\beta}1$ is the key inducer of myofibroblast transdifferentiation via de novo synthesis of ${\alpha}-smooth$ muscle actin (${\alpha}-SMA$). Since $TGF-{\beta}1$ signals through reactive oxygen species (ROS) and ROS have been shown to induce accumulation of extracellular matrix (ECM) in various tissues, this study examined if ROS play a role in $TGF-{\beta}1$-induced fibronectin secretion and ${\alpha}-SMA$ expression in human lung fibroblasts, MRC-5 cells. Methods : Growth arrested and synchronized MRC-5 cells were stimulated with $TGF-{\beta}1$ (0.2-10 ng/ml) in the presence or absence of N-acetylcysteine (NAC) or diphenyleneiodonium (DPI) for up to 96 hours. Dichlorofluorescein (DCF)-sensitive cellular ROS were measured by FACScan and secreted fibronectin and cellular ${\alpha}-SMA$ by Western blot analysis. Results : $TGF-{\beta}1$ increased the level of fibronectin secretion and ${\alpha}-SMA$ expression in MRC-5 cells in a dosedependent manner. Both NAC (20 and 30 mM) and DPI (1 and $5{\mu}M$) significantly inhibited $TGF-{\beta}1$-induced fibronectin and ${\alpha}-SMA$ upregulation. The $TGF-{\beta}1$-induced cellular ROS level was also significantly reduced by NAC and DPI. Conclusions : The results suggest that NADPH oxidase-dependent ROS play an important role in $TGF-{\beta}1$-induced fibronectin secretion and ${\alpha}-SMA$ expression in MRC-5 cells, which leads to myofibroblast transdifferentiation and progressive lung fibrosis.
