Although it has been well known that smokimg is one of the major cause of various disease and conditions, the smoking rate is still very high in Korea. A variety of smoking cessation program are provided by public organization and also by healthcare institutions. In this social enviroment, the smoker's intension and trial rates for smokimg cessation increasing, but it is also true that the succes rate is low about 30%. Therefore this study was conducted to suggest the strategies for providing the effective smoking cessation programs by exploring the factors related to recognition and behavioral intention or programs. To explain the health behavior for smoking and smoking cessation programs, the behavioral model was constructed. The model is composed of five-stages such as recognition of the program, past exprience, present smoking status, intention for smoking, and behavioral intention for cessation programs. It is results that there were very low recognition and and purchase rates for most of smoking cessation programs. Evidenced-based and effective smoking cessation progrms need to be encouraged to smokers by medical doctors, and the strategies of eucationm public realtions, and advertisement are recommended. In addition, cotinuing legal and systematic supports for smoking cessation would lower the smoking rate and ultimately ontribute to the nation;s health promotion, Recognitionm Behavioral Intention.

It has been suggested that the association between white matter hyperintensity (WMH) and carotid arterial features includes carotid plaques and carotid intima-media thickness, arterial stiffness, or remodeling. Under the hypothesis that white, matter abnormalities correlate with the configuration of the feeding carotid arteries, we use deep learning to estimate WMH volumes based solely on time-of-flight (TOF) carotid MRA images. To improve performance, we use transfer learning from a pre-trained V-Net for carotid artery segmentation. We evaluate the WMH volume prediction performance by applying Grad-CAM and confirm that our proposed transfer learning model estimates the WMH volume derived from carotid arterial features.

Background: Dry eye is a disorder of the tear film caused by reduced tear production or excessive tear evaporation. A high incidence of sicca symptoms has been noted in fibromyalgia (FM) patients resulting in serious complications. This study was conducted to evaluate the incidence of dry eye by pathogenic mechanisms and to investigate the relationship between dry eye and symptom severity in FM patients. Methods: Fifty patients that visited Maryknoll Hospital between March 2006 and December 2006 were included in the study. Enrolled patients underwent a Korean fibromyalgia impact questionnaire (KFIQ), ocular surface disease index (OSDI), Schirmer test and tear break up test (TBUT). The KFIQ and OSDI are used to assess the severity of fibromyalgia symptoms and dry eye symptoms, respectively. The Schirmer test and TBUT are used to assess reduced tear production and excessive tear evaporation, respectively. We assessed the OSDI, Schirmer test, TBUT, age and disease duration in terms of the KFIQ. Results: The incidence of dry eye was high in FM patients (12.0% by the Schirmer test and 92.0% by the TBUT test). The OSDI positively correlated with the KFIQ (p=0.006). A positive correlation was observed between the Schirmer test and the KFIQ (p=0.024), but not between the TBUT and the KFIQ. Conclusions: In this study, dry eye was found to be common in FM patients. Excessive tear evaporation was a more common cause of dry eye than reduced tear production. The patients with more severe dry eye symptoms tend to have more severe FM symptoms.(Korean J Med 73:519-524, 2007)

The vast majority of the food service industry is in the form of a highly competitive market, hence entry barriers are low and it is also difficult to achieve economies of scale. However, the domestic food service industry has been shrinking due to the recent ongoing slow growth and recession and the implementation of the Kim Young-Ran law. Consumers who are pursuing caustic are replacing eating out with fast food or light delivery food. In this study, we analyzed the data of “Food Consumption Usage Behavior” from the panel of the Korea Rural Economic Institute in 2016 to examine dietary behaviors and food consumption behavior according to consumers lifestyles. The main results are as follows. First, factor analysis and cluster analysis showed that dietary lifestyle was classified into four groups: a safety type group (19.97%); a polygonal group (30.16%); a normal type group (35.89%); and, an indifferent type group (13.98%). Second, dietary behaviors according to the dietary lifestyle were found to be satisfactory in order of polygon (m=3.637), safe type (m=3.612), mediocre type (m=3.511), and indifference type (m=3.444). Third, according to eating habits lifestyle, eating habits were more likely to be consumed in restaurants than in family units. The frequency of eating out was more frequent when eating out once a month for the safety and indifference types, but when considering polygon and regular types, it was more frequent for once per week. Fourth, as a result of examining the relationship between eating out consumption behavior and eating habits (according to eating habits lifestyle), four types of consumption attitudes based on experience emerged: seeking; safety-oriented; consumption of food.

학습자 맞춤형 교육이 중요시 되고 있는 현 시점에서 교육에서의 학습자의 특성은 점점 중요시 되고 있으며, 학습자의 특성중 성별 특성을 고려한 효과적인 맞춤 교육법에 관한 많은 연구가 진행되고 있다. 따라서 이러한 오프라인의 성별 차이에 따른 효과적인 교육방법을 교육용 게임에 적용 시킨다면 보다 효과적인 교육용 게임이 디자인 될 것이다. 이를 위해 본 논문에서는 게임 디자인 요소를 분석하여 학습자의 특성 적용을 위한 요소로 재가공 하였다. 또한 성별 차이에 따른 효과적인 교육방법과 학습 스타일을 고찰하였다. 그리고 이러한 고찰을 통해 학습자 성별 특성에 따른 교육용 게임 디자인 고려요소를 정의하였다. 고려요소는 크게 인지적, 지각적 요소로 분류하였으며, 각각 성별 특성을 반영하여 정의하였다. 본 논문은 관련 연구에 근거하여 학습자 성별에 따른 교육용 게임 디자인 고려요소의 이론적 결과를 도출했다는 것에 그 의의가 있다. 또한 앞으로 다양한 게임을 디자인하는데 참고자료로 활용될 수 있다. Although learners learn with the same educational games, they show differences in successes. This is because they do not share the same individual characteristics. Currently, there are various studies conducted on effective education according to gender among other characteristics of learners off-line. When this effective educational method according to gender is applied to educational games, it will create more effective outcomes. In addition, this study observed the effective educational method according to gender and learning styles. Through the observation, the considering factors for educational game designs according to the learners' gender was defined. These considering factors were categorized into cognitive and perceptive factors, with each definitions reflected on the characteristics of each gender. This study has its meanings in that it has conducted theoretical results of the considering factors for educational game designs based on reference studies. This study will be utilized as a reference study when designing various games.
