Objectives: The purpose of this study is to analyze the peer group factor related to adolescent smoking in the social structure(network) of adolescent groups, by applying the theory of social network. Methods: The data was collected from boy students of one high school located in Gun-Po city of Kyonggi Province. The total number of the sample was 605(223 first grade, 198 second grade, 184 third grade). The survey using the questionnaire was carried out in April 2005. Social position is finally classified as clique member, liaison, isolate group by using the NetMiner II 2.5 version. Results: The current smoking rate was 15.0%, and the life-time smoking rate was 34.9%. The smoking rate increased significantly, as the grade went up. And it was significantly high among the group having smoking friends. The logistic regression analysis showed that the odds ratio of the smoking friends group was about 4 times higher than the no smoking friends group in experience of smoking. But the smoking rate was higher significantly in the isolate group within the network composed of 2. person's social-link. The odds ratio of the isolate group was about 4.5 times higher than the clique member. However, this pattern was not found in the network composed of 3 person's social-link. Therefore, the hypothesis that clique member would have a correlation with smoking was rejected. In reality, the isolate group had a tendency of smoking more frequently. Conclusions: The result of this study suggests that the role of the peer group in smoking is to be considered in the prevention program. More attentions should be paid for the isolate group.

Traditional costume in Indonesia represents identity of a person and it displays the origin and the status of the person. Where culture and religion are fused, the traditional costume serves one of the most functions in rituals in Bali. This research aims to analyze the characteristics of Balinese costumes by focusing on the Legong dance costume. Quantitative research was performed using 332 images of Indonesian costumes and 210 images of Balinese ceremonial costumes. Qualitative research was performed by doing field research in Puri Saba, Gianyar and SMKN 3 SUKAWATI(Traditional Art Middle School). The paper illustrates the influence and structure of Indonesian traditional costume. As the result, focusing on the upper wear costume showed that the ancient era costumes were influenced by animism. They consist of tube(kemben), shawl(syal), corset, dress(terusan), body painting and tattoo, jewelry(perhiasan), and cross. The Modern era, which was shaped by religion, consists of baju kurung(tunic) and kebaya(kaftan). The Balinese costume consists of the costume of participants and the costume of performers. Bali dancing is grouped into Wali dance(sacred), Bebali dance(theatrical), and Balih-balihan dance(entertainment). The Legong dance is included in the Balih-balihan dance, and its costume developed from 1920 until present. The characteristics of Legong dance costumes are 'Theatrical,' 'Angelic,' 'Charming,' and 'Decorative.' In conclusion, the balance of religion, culture, and art gives a unique trait in Bali. The Balinese social system, which is based on Hinduism, has influenced art and its function. This relationship creates a strong structure to the Balinese ceremonial costume, especially the Legong dance costume.

Research design, data and methodology: The spatial extent of the study is all over Korea including Seoul, the metropolitan area, and local cities. The survey was conducted for about 16 days from May 7 to May 22, 2023. The survey was conducted by the surveyor visiting the subject in person, distributing the questionnaire, explaining it, and filling it out in person. For the analysis, descriptive statistics and logistic regression analysis were conducted using the SPSS 25.0 statistical package. Results: It was confirmed that the preferred assets of the Millennials and Gen Z were different by period. There was also a difference in the influencing factors between Millennial Generation and Generation Z in asset preference. Conclusions: The Millennials and Gen Z's preferred assets were different by period. The reason is interpreted as the current process of collecting assets during the asset formation period. In the future, they intend to purchase real estate assets by using financial assets as a lump sum of money. We learned the characteristics of the entire Millennials and Gen Z, in addition, the difference between income and assets is believed to have affected the difference in preference factors of Millennial Generation and Generation Z, respectively.

PAP (Palatal Augmentation Prosthesis) may be given to the patients with dysphagia; especially, who cannot achieve tongue-palate contact. PAP fills hard palate area where the tongue cannot make contact and then the distance of tongue elevation is shortened. 1bat may be expected to improve swallowing and to prevent from aspiration. The purpose of this report is to show the effects of PAP in patients with dysphagia through the videofluoroscopic study. Oral-pharyngeal swallowing post PAP is analyzed in 2 cases; one is a person who had subarachnoid hemorrhage due to aneurysmal rupture, right hemiparesis, hydrocephalus and aphamia. And the other is a person who had squamous cell carcinoma on mouth floor and he had radical neck dissection and marginal mandibulectomy. In this report, the rate of aspiration, the transit time and length measurements of anatomical structure are examined in the each frame of videofluoroscopy. The results are as follows; 1) PAP decreased the aspiration in both cases. 2) In the cases of patients with PAP, the pharyngeal transit time was decreased.

This study is about e-Book program based on human-computer interaction(HCI) system for physically handicapped person. By acquiring background knowledge of HCI, we know that if we use vision-based interface we can replace current computer input devices by extracting any characteristic point and tracing it. We decided betweeneyes as a characteristic point by analyzing facial input image using webcam. But because of three-dimensional structure of glasses, the person who is wearing glasses wasn't suitable for tracing between-eyes. So we changed characteristic point to the bridge of the nose after detecting between-eyes. By using this technique, we could trace rotation of head in real-time regardless of glasses. To test this program's usefulness, we conducted an experiment to analyze the test result on actual application. Consequently, we got 96.5% rate of success for controlling e-Book under proper condition by analyzing the test result of 20 subjects.

The age structure has been experiencing substantial change due to the decreased birth rate as well as the increased life expectancy. Gorge Magnus, an English economist, casts warnings of population ageing which has the potential of huge socioeconomic impact human society has never experienced before. The prediction that proportion of elderly people in need of oral health care will increase substantially is a new challenge to dentists in the future. The old paradigm that the aged person is just the person who was born earlier and needs the same conventional oral health care should be shifted to the new one. Elderly people tend to express their political interest related with health care system by actively participating in the national elections. The need to sustain economic status for the extended life span makes them seek eagerly esthetic health care to maintain sound social function. Most of them are under multiple chronic diseases and take related medicines. In addition, many studies report about mental change as well as physical change among the aged people. Since the prevalence of dental diseases among the aged is higher than other chronic devastating diseases, the aged seeking oral health care will increase. The aged who has different physical and psychological status as well as chronic disease and related medicine will show unexpected response to the conventional oral health care. In addition, the impact of tooth loss is substantial physically, mentally and emotionally. Dentist should prepare different approaches for the elderly dental patient.

This study evaluated the vibration use and safety of students living in the dormitories on the 12th and 14th floors by feeling uncomfortable. The measurement method was to measure the acceleration due to free vibration and single - person walking. The slab stiffness was then calculated, and the usability and safety were compared according to international standards. The natural frequency of the slab was 6.8 Hz. The natural frequency of a typical slab is around 15Hz. Therefore, the evaluation slab is judged as a flexible floor structure. It is considered that there is a high possibility of resonance in the middle of daily life because of low natural frequency and near harmonic component of walking vibration. As a result, the RMS acceleration level is within the tolerance range defined by ISO 10137 code, but the 13th floor exceeds the reference limit, so that a sensitive person could detect the vibration somewhat in the lying position.
