This research is to identify the effects of Hopelessness, as a single latter among intermediary factors causing depression, on the Internet addiction of teenagers. This research measured the teenager students' state of hopelessness using Hopelessness Depression Symptom Questionnaire (HDSQ), which demonstrates the extent of hopelessness depression symptom, and Beck Hopelessness Scale (BHS), which exhibits Beck's hopelessness scale, after conducting the analyses on the reliability of those questionnaires, and question factors. Correlations between the group in hopelessness state and the user group via the Internet Addiction Self-Test (K-scale) was comparatively analyzed. The study result reveals that reliability and validity of the questionnaire were high. As a result of the comparative analysis between the hopelessness state group and the Internet addicted user group through sub-factors of the questions, all the sub-factors showed statistically significant differences. In particular, the average score of the high risk Internet addicted user group was highest in both HDSQ and BHS. Consequently, these results imply that hopelessness affects the Internet addicted users.

The purpose of this study was to investigate pregnancy, abortion and delivery rates among Korean teenagers. The subjects of this study were 11,433 teenagers aged 13-19 years in Seoul, Pusan, Taegu, Kwangju, Incheon, Taejeon and Ansan, Korea. Data were collected from Feb. 1994 to May 1995, 16 months, by schoolnurses or the researchers. The results showed pregnancy rate was 7.2 per 1,000 teenagers, the abortion rate was 4.3 per 1,000 teenagers, and the delivery rate was 1.2 per 1,000 teenagers. In the pregnancy experience, the main factors related to teenage pregnancy were love or marriage engagement. In the abortion experience, 53.9% of teenagers had had more than two abortion experiences, 38.1% midtrimester abortion, 22% complications after abortion, 36.0% sexual activity after abortion and 86.7% the financial support from partners or friends for abortion. In the delivery experience, 64.3% of teenagers delivered with no prenatal care and 42.9% had a delay in realizing they were pregnant. Fifty percent were delivered by non-professionals in non-medical institutions.

Since a smart phone has been popular, 91% of the internet users are utilizing the technology in all places for chatting and messenger which overtake share of voice and visual call utilization. The phenomenon is remarkable to young generations between teenager and thirties, which leads to mobile messenger shopping such as mobile digital voucher and coupon buy. In this research, we clarify whether traditional gift-giving motivations works on digital coupon gift-giving, and two technology acceptance model factors: perceived usefulness and ease of use affects between motivations and intention to gift-giving. The result shows three traditional gift-giving motivations: experiential, obligated and practical attitude affects intention to digital mobile coupon gift-giving and ease of use of the digital mobile coupon works parameter of the relation rather than usefulness. In other words, gift-giving purpose digital coupon users give a gift with traditional gift-giving motivation but has the stronger intetnion to gift-giving by technology ease of use.

The purpose of this study was to investigate the rate of pregnancy, abortion, delivery and contraceptive use and the relationship between the related factors and the early coitus among Korean teenagers. Method: The subjects of this study were 12,733 teenagers age 13-19 years in 7 major cities and 9 provinces in Korea. Data was collected from 2 Oct., to 28 Oct., 2000 and analyzed by using SPSS 10.0 Program. Results: The results showed pregnancy rate 4.5%, delivery rate 0.5%, abortion rate 0.4%. Adolescent girls who experienced coitus relatively went to vocational school, coeduaction school, night school in the general characteristics (p=0.000). Adolescent girls who experienced coitus tend to go to video room (18.5%), go the singing room (60.7%), the bar (54.8%), petting with the partner during the dates. There were overlapping juvenile delinquencies such as drinking (89.2%), pornography (65.3%), bond inhalation (2.7%), leaving homes (43.7%), smoking (14.5%), cyber sex (70.8%), phone sex (12.9%). Adolescent girls who experienced coitus were more suffering from Wangtta (26.1%) than who had not. They showed significant positive attitudes toward coitus; such as feeling of excitement (6.6%), nature (37.9%), beauty (8.7%). On the other hand, they had more guilty (2.8%) than the inexperienced (p=0.000). The main factors relating to early coitus were 'to confirm love' (46.9%), 'afraid of rejection' (32.2%). They think the benefits of coitus were 'more intimacy with boyfriends' (20.6%), 'satisfaction of curiosity' (16.8%). The losses on coitus were 'worry about pregnancy' (73.7%) and 'unability to refuse sexual contacts' (28.7%) Conclusion: It could be concluded that it is necessary to plan different sex education programs according to general characteristics and delinquency behaviors of teenage girls in Korea.

Autism is characterized with an abnormality of reciprocal social relatedness and of communication development. Also, autistic children show repetitive and stereotypical behavior pattern and deficiency of endurance against change. Dental problems related to autism are self-injury and trauma from accidents. Sometimes self-injury is due to discomfort resulting from restoration and local anesthesia. Also, gingivitis and multiple caries are common because of poor oral hygiene. Autistic children are anxious about visual and auditory stimuli because they don't understand the dental procedure. If the face of any changes in their daily life, their behavior becomes uncontrollable. In a setting such as the outpatient office, an autistic child's uncontrollable behavior makes it difficult to carry out proper treatment. If they need treatment under general anesthesia, it is very difficult to manage them in a ward as they are severly anxious about being admitted to a hospital. Therefore it is necessary to treat these children according to a specific management program under general anesthesia in an outpatient office. This case study reports of a 14 year old autistic teenager who although became uncontrollable because of the pain from multiple caries and from anxiety of the dental treatment eventually received treatment under general anesthesia and under conscious sedation in an outpatient office.

Purpose: Epitope spreading is a phenomenon in which distinct subdominant epitopes become major targets of the immune response. Heat shock protein (HSP) 60 from Porphyromonas gingivalis (PgHSP60) and peptide 19 from PgHSP60 (Pep19) are immunodominant epitopes in autoimmune disease patients, including those with periodontitis. It remains unclear whether Pep19 is a dominant epitope in subjects without periodontitis or autoimmune disease. The purpose of this study was to determine the epitope spreading pattern and verify Pep19 as an immunodominant epitope in healthy teenagers using dot immunoblot analysis. The patterns of epitope spreading in age-matched patients with type 1 diabetes mellitus (type 1 DM) and healthy 20- to 29-year old subjects were compared with those of healthy teenagers. Methods: Peptide from PgHSP60, Mycobacterium tuberculosis HSP60 (MtHSP60), and Chlamydia pneumoniae HSP60 (CpHSP60) was synthesized for comparative recognition by sera from healthy subjects and patients with autoimmune disease (type 1 DM). Dot immunoblot analysis against a panel of peptides of PgHSP60 and human HSP60 (HuHSP60) was performed to identify epitope spreading, and a densitometric image analysis was conducted. Results: Of the peptide from PgHSP60, MtHSP60, and CpHSP60, PgHSP60 was the predominant epitope and was most consistently recognized by the serum samples of healthy teenagers. Most sera from healthy subjects and patients with type 1 DM reacted more strongly with PgHSP60 and Pep19 than the other peptides. The relative intensity of antibody reactivity to Pep19 was higher in the type 1 DM group than in the healthy groups. Conclusions: Pep19 is an immunodominant epitope, not only in autoimmune disease patients, but also in healthy young subjects, as evidenced by their robust immunoreactivity. This result suggests that the Pep19-specific immune response may be an initiator that triggers autoimmune diseases.

The purpose of this study is to verify a correlation between flexi-bar exercise and improvement of trunk strength and body composition in juvenile soccer players. The subjects were 11 teenager juvenile soccer players who conducted flexi-bar exercise half an hour daily three times a week for eight weeks. They were tested for trunk muscles strength, body composition and correlation. The result showed that trunk muscles strength improved significantly(p<.01) and weight, Rt. arm muscle mass, Rt. leg muscle mass, and Lt. leg muscle mass(p<.05), Lt. arm muscle mass, trunk muscle mass, and body muscle mass(p<.01) improved significantly as well while Lt. arm fat mass, Rt. leg fat mass, and Lt. leg fat mass decreased significantly(p<.05). In the correlation analysis, the more trunk muscle mass and trunk muscles strength increased, the more muscle mass of body regions increased, which was a positive correlation whereas fat mass of body regions decreased, which was a negative correlation. It was verified that there was a correlation between flexi-bar exercise and improvement of trunk muscles strength and body composition for juvenile soccer players.

On the basis of the study intended to research by cross-sectional study keeped pace with semi-longitudinal study the growth accelerating phenomena that MGA(Maximum Growth Age) in teenager's body height. The duration of study is from Oct. 1st. 1991 to September 30 1992 and the data are analysed through computer. The body height and MGA of Koreans who had been for during the period from 1898 to 1973 proved transition of the growth accelerating phenomena by research data reported between 1913 and 1990. The results are as follows: 1. Maximum Growth Age The MGA's in body height of male are respectively the age 15.024 in 1913, 14.28 in 1940, 13.65 in 1959, 13.86 in 1967, 12.52 in 1983, 11.39 in 1987, 12.36 in 1990, while those of female are the age of 12.0 in 1940, 12.36 in 1959, 10.45 in 1969, 11.15 in 1985, 10.27 in 1988, 10.23 in 1990 ; these data show that the MGA of the Korean has been getting younger. 2. The correlation of the MGA's in body height are as below ; Male ; r = -0.448(p<0.01) Female ; r = -0.404(p<0.05) 3. The equation of linear regression of MGA's in body height are as below ; Male ; Y(MGA) = -0.0316X(the year)+75.297 Female ; Y(MGA) = -0.035X(the year)+79.986 4. The MGA's in body height are shown in Table 3. 5. From the transition of the growth accelerating phenomena, we can compute the fact that the MGA's has been getting younger by 0.3 year per 10 years. 6. The future growth accelerating phenomena in body height, the MGA's of male are respectively the age 12.25 in 1995, 12.09 in 2000, 11.94 in 2005, 11.78 in 2010, while those of female are the age of 10.16 in 1995, 9.98 in 2000, 9.81 in 2005, 9.64 in 2010, these data show that the MGA of female are more younger than that of male.

The purpose of this study was to understand the experiences of adolescent who are scheduled to discharge from child care institution. Data was gathered from 5 adolescent who are scheduled to discharge from child care institution within 1-2 years and qualitative case study used for data analysis. The analysis showed that adolescents of child care institution experienced separation from their parents and entered the institution with no consideration of their feelings. Then, they stayed in the institution for many years, even throughout their teenager-years, before they are released from the institution. Although feelings they experience of separation from the institution included worry and tension, those feelings were different from feelings they received from separation from their parents in a way that the former was more hopeful and future forwarding. Based on these findings, services sensitive to adolescent who are scheduled to discharge from the institution are suggested.
