This study was carried out to investigate the body weight controls and eating disorders of university students in Gunsan. The subject of the present study included 229 male students (53.8%) and 197 female students (46.2%), totalling 426 students from Kunsan University. The subjects consisted of 56 underweight (13.1%), 265 with normal weight (62.2%), and 105 overweight (24.6%). Especially, in females, 20.8% of them were underweight, which is 6.6% higher than males, showing a significant difference (p<0.001). Regarding body image, 21.8% of the males thought they were fat, while 40.6% of the females thought they were fat. Regarding the perceived body type, shown in the difference between their own size and the ideal size, males recorded 0.03, while females recorded 1.75, showing a major significant difference (p<0.001). Regarding body satisfaction, 33.2% of the males were unsatisfied, while 52.8% of the females were unsatisfied (p<0.001). The social expectations of the male subjects' sizes and weights recorded 2.04, while that of females recorded -2.51, showing that people's opinions expected the female subjects' bodies to be thinner (p<0.001). Additionally, the social expectation of the subjects' weight control recorded an average of 15.22 (13.92 for males, 16.73 for females), showing that the female subjects' felt that people's opinions wished them to lose their weight (p<0.001). Regarding the recognition on weight control, interested males were 49.4%, while interested females were 86.8%, showing the females superior rate (p<0.001). The beliefs in relation to weight control recorded an average of 62.01, with the score of females of 67.89 being significantly higher than that of males which was 56.96. The subjects showed a relatively positive response towards weight control (p<0.001). EAT-26 score was employed to determine the eating attitudes in relation to gender. Here, the final score of males was 15.46, which was significantly lower than that of females, which was 22.21 (p<0.001). Furthermore, regarding the score of eating attitudes in relation to obesity index, the eating disorder scale scores on the questions related to bulimia and diets to lose weight as weight increases were high. However, the eating disorder scale score on oral control, which actually controls food, was low. To control the expansion of excessive weight control attempts and their side effects, the recognition of the students' body types needs to be corrected, and nutrition education programs on eating habits and eating disorders to foster proper weight loss are deemed necessary.

for the low information goods which will be traded through Internet is impossible to manage with previously existed payment system. The reason is that it's not economic because the management cost is bigger than the benefit of the information goods trade. Therefore, recently, there have been micropaymentresearches such as "Milicent", "PayWord", "MicroMint", and "iKP", etc. Though these methods don't have any problem with the low cost of the mechanism and the satisfaction of adequate security, they have big problem with the use of the unnecessary account and the aggregation of payment bill. The PayHash system which has been developed in this study simplifies the system's mechanism with "one-way hash function" which is used in generation, payment, and verification of the bill. And the system removed the generation and use of unnecessary account by making one customer have one account. The system solve the problem of the payment aggregation by using the last payment hash value and its index. And the system improves its performance by reducing the use of "digital signature" drastically, as well. As the result of this study, the PayHash system made it possible for the participants of the Internet Commerce to trade the lowest cost goods through efficient maintenance.o trade the lowest cost goods through efficient maintenance.

Recent studies have revealed that collagen peptide plays a protective role on skin by improving the activity of antioxidants and acts as an inducer of skin regeneration. To evaluate the efficacy of low molecular weight collagen peptide for skin recovery after non-ablative 1550 nm fractional photothermolysis laser. 10 volunteers were randomly divided into two groups. Both control and experimental groups received fractional photothermolysis treatment. In the experimental group, 5 subjects received oral collagen peptide 1,000 mg/day for 8 weeks. Before and after the treatment, we measured elastic recovery of skin, transepidermal water loss (TEWL) and erythema index (EI) for each patients. The evaluation of clinical results showed that elastic recovery of skin is higher in the experimental group than the control group (p < 0.05). TEWL have no significancy between two groups and erythema rapidly disappeared in the experimental group. On the quartile grading scale, the mean patient satisfaction 4 weeks after the fractional photothermolysis treatment was 2.0 in experimental group and 1.2 in control group. The low molecular weight collagen peptide appears to be an effective conservative therapy for skin recovery after non-ablative 1550 nm fractional photothermolysis treatment.

Purpose: This pilot study was conducted to evaluate the cleaning efficacy of an angled implant brush for home oral hygiene of full-arch fixed-implant prostheses. Methods: Forty-one patients treated with a full-arch implant rehabilitation in the maxilla or mandible (164 implants) for at least 4 months were enrolled. The screw-retained fixed prostheses were removed and baseline (T0) parameters were recorded, including plaque index (PI), probing depth (PD), and bleeding on probing (BOP). All patients completed a 5-item questionnaire on hygiene maintenance and received an implant brush for home hygiene. After 1 month (T1) PI, PD, and BOP were recorded again and patients completed a 7-item questionnaire to evaluate their satisfaction with the implant brush. One-way repeated-measures analysis of variance was conducted to evaluate the significance of changes in PI, PD, and BOP. A P value <0.05 was considered to indicate statistical significance. Results: A statistically significant reduction of BOP (0.62±0.6 at T0 vs. 0.5±0.5 at T1; P=0.032) was found, while no statistically significant changes in PD (1.74±0.5 mm at T0 vs. 1.77±0.5 mm at T1; P=0.050) or PI (1.9±0.7 at T0 vs. 1.7±0.7 at T1; P=0.280) occurred. According to the 7-item questionnaire, patients reported no difficulty in using the angled brush (63.4%) and deemed it highly (46.3%) or very highly (4.8%) effective in improving their home oral hygiene. Conclusions: Within the limits of the present pilot study, the patients experienced a reduction of BOP 1 month after being instructed to use the angled implant brush. The angled implant brush appeared to be a well-accepted device for home-care hygiene of full-arch fixed-implant rehabilitations.

This study was aimed to study the effects of adolescents' outdoor sports and e-sports activities on their holistic health. In order for this, adolescent holistic health has been divided into three categories: physical health, mental health, and social health; and reviewed existing research on outdoor sports and e-sports. The research has found several variables for measuring the correlation between the two types of sports. The variables cover four areas: 1) General Information, determined by gender, age, preferred sport, and length of play; 2) Physical Health, as measured by six questions in the basic PAPS (Physical Activity Promotion System) survey; 3) Mental Health, as measured by stress index, self-efficacy, subjective health, and self-esteem; and 4) Social Health, as measured by variables relating to family, friends, school, and society. A total of 36 questions were devised, with 1-4 questions in each area. Primarily it examined the mental health social health. As a result, it was found that three factors have a difference such that the significance of self satisfaction. family relationships, friendships is 0.064, 0.012, 0.088 respectably.

Objectives: To observe the effect of acupuncture and nerve block combination treatment on adhesive capsulitis patients. Methods : 59 voluntary patients were randomly assigned to acupuncture treatment group(E group, n=22), nerve block treatment group(W group, n=17) and acupuncture and nerve block combination treatment group(EW group, n=20). The E group received acupuncture treatment on LI15, $TE_{14}$, $GB_{21}$ and Master Dong's acupuncture points, Shin-gwan and Gyun-joong, twice a week for 4 weeks. The W group received suprascapular nerve block, subacromial injection and trigger point injection, twice a week for 4 weeks. The EW group received the same treatment as the W group and after 5minutes of rest, successively received the treatment identical to that of E group. All three groups were instructed to practice groups were instructed to practice self exercise during their daily lives. Evaluations were made before treatment and after 1, 2, 3 and 4week treatment. Constant Shoulder Assessment(CSA), Shoulder Pain and Disability Index(SPADI), Range of Motion(ROM), the patient's treatment satisfaction measured by Visual Analogue Scale(VAS) and Digital Infrared Thermographic Imaging(DITI) were used as assessment tools. The obtained data were analyzed and compared. Results : The E group showed significant improvement(p<0.05) on CSA, SPADI, VAS and DITI. As for ROM, Adduction and Extension improved significantly(p<0.05). The W group showed significant improvement(p<0.05) on CSA, SPADI, VAS and DITI. As for ROM, Abduction and Extension improved significantly. The EW group showed significant improvement(p<0.05) on CSA, SPADI and VAS. As for ROM, Adduction, Abduction, Extension and Flexion improved significantly. The improvement of CSA, VAS and Abduction ROM in the EW group was significantly(p<0.05) superior compared to the groups treated with single type of treatment. Conclusion : It is suggested that acupuncture and nerve block combination treatment for adhesive capsulitis patients is more effective than the two single treatments. Through further studies, the acupuncture and nerve block combination treatment model may be developed into East-West Collaboration Model in treating adhesive capsulitis.

User movement is an important factor in determining the amount of the acquired knowledge and information about space contexts. A reasonable circulation plan affects the spatial usage, space revitalization, and activity satisfaction, and is ultimately a means to increase spatial usefulness. On the other hand, a disorderly circulation system causes negative experiences due to difficulties in wayfinding. This research identified the importance of a pedestrian circulation system analyzing the correlation between the spatial configuration index and pedestrian movement, and visitors' movement in the leisure space by using Space Syntax. The research area, Ouam-ri, where numerous guests visit this designated folk village, is a typical case in which a settlement space is used as a leisure space. There was a great deal of risk that visitors would get lost while wandering through the space. Also, it is difficult to induce visitors to tour economically even though the pedestrian circulation configuration of Ouam-ri forms the natural moving line because of its typical tree structure. Additionally adjusting and to supplementing the pedestrian system is required in order for the traditional village, a settlement space, to be used as a leisure space.

We investigated the prevalence of eating disorder risk group and its relationship with Physique status and eating behavior among high school students in Daejeon. In May - June 2002, 350 students were sampled from 6 high schools in Daejeon by multi-stage cluster sampling and assessed with self-completing questionnaires. We used the Korean version of Eating Attitude test(EAT-26) to screen eating disorder risk group. and other instruments to screen physique status and eating behavior. The response rate was 91%(total 320) and numbers of female students were 167(52.2%) and male students were 153(47.8%). Average age was 16.0${\pm}$0.35 years, and average body-mass index(BMI) and PIBW(Percent Ideal Body Weight) were 20.9${\pm}$3.3 Kg/m2 and 102${\pm}$4.2% in male students, 20.2${\pm}$3.7 Kg/m2 and 98${\pm}$7.2% in female students(p<0.0001). Over 50% of the subjects were dissatisfied with their body shape; the degree of dissatisfaction with body shape was higher in those who believed themselves to be fat. Mean score of EAT-26 was higher in female students (10.78${\pm}$7.36) than male students(6.07${\pm}$4.39)(p<0.0001). The prevalence of high risk eating disorder group was 2.6% in male students, 11.4% in female students(p<0.0001). Eating behavior was better in female students than male(p<0.0001). Eating behavior was significantly higher in eating disorder risk group in both sex. Therefore eating disorder symptomatology was highly prevalent among high school students in Daejeon. And this symptomatology has a more close relationship with physique status and eating behavior in female students.

The purpose of this study is to investigate the effects of flash panorama-based virtual field trips (VFT) as a supporting tool for geological field activity on middle school students' spatial visualization ability, conceptual understanding, and perceptions. A total of 17 middle school students participated in a three day long actual geological field trip around Jeju Island where a three-phase instructional model is applied for utilization of flash panorama-based VFT, which was proposed by Kim and Lee (2011). With one-group pretest-posttest pre-experimental design, data were collected using questionnaire and were analyzed to find out a change in students' spatial visualization ability and volcanic concept understanding, and their perceptions about the utilization of flash panorama-based VFT. Findings are as follows: First, the effect of utilizing flash panorama-based VFT in actual field trip revealed that there was meaningful increase in 'spatial relation' category of spatial visualization ability and 'knowledge' and 'comprehension' domains of volcanic concept understanding. Second, majority of students showed positive gain index in both spatial visualization ability and volcanic concept understanding. Lastly, participating students showed much interest and high satisfaction, and positive perception on the use of VFT. They also perceived that the utilization of flash panorama-based VFT could help in carrying out an actual field trip in terms of cognitive and geographical factors.

Purpose: The purpose of this study is to determine the correlation between the correction loss of hallux valgus angle and the severity of valgus angle of the second toe. Materials and Methods: We selected 312 cases from 268 surgical patients with hallux valgus deformity receiving distal chevron osteotomy. For a radiological evaluation, we analyzed the changes in the hallux valgus angles, first to second intermetatarsal angles, and valgus angle of the second toe post index operations. All patients were women; the mean age was 46 years. The mean follow-up period was 17 months. Results: The mean hallux valgus angle was $33.6^{\circ}$ preoperatively (range, $25.7^{\circ}{\sim}44.8^{\circ}$), $13.1^{\circ}$ (range, $8.4^{\circ}{\sim}16.4^{\circ}$) after 4 weeks of postoperative period, and $17.1^{\circ}$ (range, $9.4^{\circ}{\sim}28.5^{\circ}$) at their final follow-up. The mean valgus angle of the second toe was $8.4^{\circ}$ preoperatively (range, $2.0^{\circ}{\sim}25.8^{\circ}$) and $8.3^{\circ}$ (range, $1.7^{\circ}{\sim}24.9^{\circ}$) at the final follow-up. Preoperatively, there was a positive correlation between the valgus angle of the second toe and hallux valgus angle (r=0.747, p=0.001). The correction loss of hallux valgus angle had a significant correlation with the severity of valgus angle of the second toe (r=0.802, p=0.001). Conclusion: The existence of the second toe valgus deformity may present itself as a cause of correction loss of hallux valgus angle. The preoperative measurement of the second toe valgus angle may be a good predictor of correction loss; therefore, thorough preoperative warning on the possibility of correction loss should be conducted to maximize patient satisfaction after the procedure.
