Background: Smokers with lung adenocarcinoma have a worse prognosis than those who have never smoked; the reasons for this are unclear. We aimed to elucidate the impact of smoking on patients' prognosis and the association between smoking and clinicopathologic factors, particularly histologic subtypes. Methods: We reviewed the records of 233 patients with pathologic stage T1-4N0-2M0 lung adenocarcinomas who underwent surgery between January 2004 and July 2015. The histologic subtypes of tumors were reassessed according to the 2015 World Health Organization classification. Results: In total, 114 patients had a history of smoking. The overall survival probabilities differed between never-smokers and ever-smokers (80.8% and 65.1%, respectively; p=0.003). In multivariate analyses, the predominant histologic subtype was an independent poor prognostic factor. Smoking history and tumor size >3 cm were independent predictors of solid or micropapillary (SOL/MIP)-predominance in the logistic regression analysis. Smoking quantity (pack-years) in patients with SOL/MIP-predominant tumors was greater than in those with lepidic-predominant tumors (p=0.000). However, there was no significant difference in smoking quantity between patients with SOL/MIP-predominant tumors and those whose tumors had non-predominant SOL/MIP components (p=0.150). Conclusion: Smoking was found to be closely associated with SOL/MIP-predominance in lung adenocarcinoma. Greater smoking quantity was related to the presence of a SOL/MIP component.

Objectives: The purpose of this study was to evaluate the impact of dentin roughening and the type of composite resin used (either bulk-fill flowable or nanohybrid) on the restoration of non-carious cervical lesions (NCCLs) with an 18-month follow-up period. Materials and Methods: This prospective split-mouth study included 36 patients, each with a minimum of 4 NCCLs. For each patient, 4 types of restorations were performed: unroughened dentin with nanohybrid composite, unroughened dentin with bulk-fill flowable composite, roughened dentin with nanohybrid composite, and roughened dentin with bulk-fill flowable composite. A universal bonding agent (Tetric N Bond Universal) was applied in self-etch mode for all groups. The restorations were subsequently evaluated at 6, 12, and 18 months in accordance with the criteria set by the FDI World Dental Federation. Inferential statistics were computed using the Friedman test, with the level of statistical significance established at 0.05. Results: The 4 groups exhibited no significant differences in relation to fracture and retention, marginal staining, marginal adaptation, postoperative hypersensitivity, or the recurrence of caries at any follow-up point. Conclusions: Within the limitations of the present study, over an 18-month follow-up period, no significant difference was present in the clinical performance of bulk-fill flowable and nanohybrid composite restorations of non-carious cervical lesions. This held true regardless of whether dentin roughening was performed.

Development of digital technology, which is individualizing and differentiating the world, makes time and space facilitate multi-layering in the contemporary society. It gives a large influence on the contemporary architecture that inducing the visual and spatial experience. Also, It generates new images through the skin of architecture, which implies the contingent and fluid characteristics. These phenomenon show that various parameters are working on the architectural skin simultaneously. Such complexity make the structure of open space and diversity that are homogenized and synchronized. Like this, the architectural skin implies 'multiplicity': qualitative difference which is enable to change and create new images. This characteristic generates instant images changing variously and semantics constantly by the function of skin as a filter. Also, the architectural skin integrates or relocates of relationships between the various information and elements appearing in contemporary society in order to escape the customary relationship between internal and external. Furthermore, the inside and outside of the mixture as a collection of sense has been recognized as one image. This image of mixture consists of one unified continuous integration and extend the meaning of a fluid interface not just surface of the building. The skin of the contemporary architecture is very technical, so its meaning and role is expanded as a complex that exchange interaction. This means that the skin itself has functional elements of the integrated multiple skin to assist. Also it can form a multi-layered relationship and act as a wide range of interfaces depending on the perception of the observer. Therefore the multiplicity of the architectural skin indicates the importance as a boundary that generate images of new life through the sensory perception and implicit force. And it shows potential as the intermediary to try to communicate.

According to rapid increment of demand for wireless Local Area Network (LAN), the HyperLAN of 5.1-533GHz and 5.725-5.825GHz is newly allocated for wireless LAM in many regions over the world. Also, because most of mobile communication equipments are small, the size of antenna is important factor of effective design. In this paper, the compacted and wide bandwidth antenna is designed for wireless LAN at 5GHz band. Although the structure of U-shaped slot antenna is simple, It has large bandwidth of $10-40\%$. Also, the U-slot antenna has good radiation pattern. However, in general, the size of U-slot antenna is large. Therefore, it is difficult to apply to wireless equipment such as PDA and Notebook. This proposed antenna has a wide bandwidth by U-shaped slot in rectangular patch and is compacted by using two layered dielectric substrates and foam. For the design of U-slot antenna, the Finite Difference Time Domain method is applied. Also, the method of MPI parallel program is used for the enhancement of the analyzing speed of the FDTD method.

Background: In India, tobacco consumption is responsible for one of the highest rates of oral cancer in the world, the annual oral cancer incidence is steadily increasing among young tobacco users. Studies have documented efforts taken by physicians, doctors and even dentists, in the form of individual or group counseling to curb tobacco use in smoke or smokeless form. However, which one is more effective, still remains an unanswered question. The aim of the study was to compare the effectiveness of individual and group counseling for cessation of the tobacco habit amongst industrial workers in Pune and to compare quit rates. Materials and methods: An interventional study design was selected for 150 industrial workers which were stratified randomly into three groups (control, individual and group counseling groups) and interventions were provided to individual and group counseling groups over a period of six months, which were then compared with the control group that received brief intervention at the start of the study. Results: There was significant difference in the quit rates of the participants in the individual counseling group (ICG) and group counseling group (GCG) when compared at 6 months with the control counseling group (CCG). In the individual counseling group was 6% while in group counseling group it was 7.5% after six months of counseling. Conclusions: No conclusion could be drawn whether individual or group counseling were better interms of quit rates. Individual and group counseling groups were definitely better than the control group when compared at 3 and 6 months, respectively.

A recent accelerated globalization has changed every aspect of consumers' life on the globe, thus understanding the similarity and the difference among people in the world became the crucial element of business for many global companies. As one of the most globalized industries in Korea, fashion businesses also require urgent assistance of academics in understanding global consumers. This study aimed to analyze cross-cultural fashion marketing studies published in two respectful journals in fashion studies: Journal of Korean Society of Clothing and Textiles and Journal of the Korean Society of Costume. Four researchers independently searched the target journals to locate studies using cross-cultural approaches. A total of 45 cross-cultural studies published in two journals between 1977 and 2005 were found and analyzed. The major findings could be summarized as followed. First, the US was the most frequently studied country followed by China, Japan, Hong Kong and others. Second, popular subjects of cross cultural studies in fashion marketing were fashion marketing environment and management rather than consumer psychology. Third, about 78% of the sampled studies were using quantitative approach, and statistical methods such as factor analysis, t-test, ANOVA, and $X^2$ analysis were commonly used. Finally, problems in sampling methods, translation of scales, and equivalence of concept, measure and sample were analyzed. Suggestions for future cross-cultural studies were discussed.

This study is a basic study of the stone cultural landscape resources of Jeju Island with the value of world heritage. It has the ultimate purpose of providing basic resources for the advantages of various Jeju local resources and future conservation and management. Literature research and field survey were conducted to derive the landscape characteristics of Jeju stone cultural resources. and Research for recognition of stone cultural resources and image analysis were performed in parallel. Accordingly I would like to consider the recognition of the Jeju stone cultural landscape held by Korean and Chinese. As a result of the research, Stone is a typical local resource in Jeju, and the greatest feature of the stone was its natural nature. and In the image of the cultural resources of stone, he highly appreciated the image of "Harmonious", "Attractive" and "Unaffected". Recognized Field walls as "Beautiful" and Dolhareubang as "Familiar". And the most preferred stone cultural resources in Korea and China are surveyed in order of Field walls and Dolhareubang, and you can see that there is a difference between them in the evaluation.

This Study is divided into 5 separate Parts and an Abstract. Part Ⅰ, Ⅱ consist mostly of a collection of problems, current status, motives and the future of ADR. In Pert Ⅲ was described ADR as policies of judicial settlements. We must accept that a diversity of legal culture will always continue to exist. Accordingly we must learn to accommodate those differences of 'culture' around us and to harmonize conflicting laws. This recognition of our reality should in no way be confused with pessimism. In fact if one accepts this perspective of the world ,the study of law seems enriched and becomes academically more challenging. Recently, in the United States, interest in alternative settlement mechanism has increased greatly, which leads me to wonder why such a phenomenon has taken place. In the first place, I'm amazed at the extent to which conciliation or mediation-or the new word, I guess, is alternative dispute resolution, which by now has its own acronym, "A.D.R,"-have gained attention here recently. When 35 years ago, there was virtually no interest in conciliation in this country at the time. What interest there was, was no in the law schools. But looking at the situation now, we have a spate of publications on the subject; we have organizations that are established for no other reason than to promote alternative dispute settlement. We have courses in the law schools. The American Association of Law Schools and the American Bar Association also have active programs. So we have to ask ourselves why. The difference between now and 35 years are striking. On the other hand, I think the interest of the public in ADR has probably been greatly enhanced by the politics of the so-called "poverty programs." I think that many of these assistance programs for the poor-and I do think the "poor" have become a rather expansive political movement beyond simply taking care of the most marginal people of society-have generated money to explore this kind of dispute resolution.

Purpose: This study was conducted to collect and analyze real world data to evaluate the effectiveness and safety of comprehensive traditional Korean Medicine treatment on quality of life, anorexia and cachexia of cancer patients. Methods: We analyzed medical records of 62 cancer patients admitted to O-I Dang Korean Medicine Hospital from February 2018 to February 2019. The primary outcome was a change score in the Anorexia/Cachexia Subscale of Functional Assessment of Anorexia/Cachexia Therapy (FAACT). The secondary outcomes were Functional Assessment of Cancer Therapy-General (FACT-G), Trial Outcome Index(TOI) of FAACT, 11 point Pain Intensity Numeric Rating Score (11 PI-NRS) and Patient Global Impression of Change (PGIC) and adverse event. Results: Cachexia and quality of life in cancer patients assessed by FAACT, increased by $5.59{\pm}14.83$ (p=0.004) after treatment. PI-NRS was reduced by $2.10{\pm}1.81$ (p<0.001) and TOI and FACT-G total scores were increased by $5.17{\pm}11.70$ (p=0.001) and $3.59{\pm}10.94$ (p=0.012), respectively. These results were also clinically meaningful assessed via minimal clinically important difference (MCID). There was no severe adverse event. Conclusion: These findings suggest that comprehensive traditional Korean Medicine treatment might be effective and safe strategy for improving quality of life, anorexia, cachexia and pain of cancer patients. Further advanced studies with controlled group and more participants with rigorous design are needed to ensure these findings.

From published data of mature forests worldwide, Raich and Nadelhoffer suggested that total belowground carbon allocation (TBCA) could be estimated from the difference between annual rates of soil respiration and aboveground litterfall. Here we analyze new measurements of IRGA-based soil respiration and litterfall of natural mature oak forests dominated by Quercus mongolica in Korea. Rates of in situ soil respiration and aboveground litter production are highly and positively correlated. Our results disagree with the Raich and Nadelhoffer model far world forests. A regression analysis of the data from Q. mongolica forests produced the following relationship: annual soil respiration : 141 + 2.08 ${\times}$ annual litterfall. The least squares regression line has a more gentle slope (2.08) than the slope (2.92) described by Raich and Nedelhoffer for mature forests worldwide. The regression slope of our study indicates that, on average, soil respiration is about two times the aboveground litterfall-C, which further implies that TBCA is similar with annual aboveground litterfall-C at natural Q. mongolica forests in Korea. The non-zero Y-intercept (141) of the regression indicates that TBCA may be greater than litterfall-C where litterfall rate are relativery low. Over a gradient of litterfall-C ranging from 200-370 g C $m^{-2}yr^{-l}$, TBCA increased from 350-530 g C $m^{-2}yr^{-l}$.
