Purpose: Adolescence is a critical period for growth and development; hence, knowledge about good food habits is essential amongst children. This study was conducted to investigate prevalence of awareness among food sellers, which could probably influence children's health and perceptions on food around schools towards adulterated food management beliefs, competencies, and food safety practices. Methods: Data was collected from 195 dealers around 25 elementary, middle and high schools in Daegu and Gyeongbuk provinces using a self-administered questionnaire in July and August, 2015. The data was analyzed using frequency analysis, one-way analysis of variance, $x^2$-test, factor analysis, and reliability analysis by SPSS Statistics (ver. 23.0). Results: A total of 121 people (62.1%) reported satisfaction of providing information and education on adulterated food. The perception of hazardous substances was found to be related to food poisoning bacteria and viruses (65.6%), heavy metals (42.1%), environmental hormones (36.4%), residual pesticides (27.2%), and irradiated food (26.7%). The perceived score on hygiene practices for processed food seller was $4.04{\pm}0.56/5.00$ and for cooked food seller was $4.09{\pm}0.45$. The capacity of adulterated food management practice of food sellers was significantly correlated with food knowledge on adulteration and public relation capacity, necessity of adulterated food management, and perception of hygiene practices (p<0.01). Similarly, knowledge and public relation capacity were significantly different according to ages (p<0.01). The perception of the necessity of adulterated food management was significantly different according to education levels (p<0.05), and the evaluation of hygiene practices was significantly different according to age (p<0.01). Conclusion: In order to solve the problem of adulterated food, which is one of the four social evils, and to strengthen the capacity of children to solve social problems, various practices like campaign on health promotion, goof food habits, education, and adulterated food management, should be actively promoted not only for children but also for food sellers around the schools.

Background The radial forearm osteocutaneous free flap is considered to be the standard technique for penile construction. One year after their operation, most patients experience a softened phallus, so that they suffer from difficulties in sexual intercourse. In this report, we present our experience with phalloplasty by radial forearm osteocutaneous free flap, as well as an evaluation of the etiology and treatment of the softened phallus. Methods Between March 2005 and February 2010, 58 patients underwent phalloplasty by radial forearm osteocutaneous free flap. Most of their neophallus had been softened subjectively and among them, 12 patients who wanted correction were investigated. We performed repetitive fat injection, artificial dermis grafting, silicone rod insertion, and rib bone with cartilaginous tip graft. Physical examination, plain radiograph, computed tomography, bone scintigraphy, and satisfaction scores were investigated. Results Most of the participants' penises have been softened after phalloplasty, and the skin elasticity had been also decreased. On plain radiograph, the distal end of the bone was self-rounded; however, the bone shape of the neophallus had no significant interval changes or resorption. Computed tomography showed equivocal density of cortical bone. On bone scintigraphy, the bone metabolism was active at 3 months postoperatively, and remained active 9 years postoperatively. Conclusions The use of a rib bone with cartilaginous tip graft could be an option for improvement of the softened phallus. Silicon rod insertion is also worth considering for rigidity of the softened phallus. Decreased rigidity due to soft tissue atrophy could be alleviated with repeated fat injection and artificial dermis grafting.

Purpose: The Inaba's procedure, the treatment of osmidrosis axillae, has the advantages of low recurrent rate and easy to learn, yet it produces early postoperative discomfort and scar formation by tie - over dressing. The authors modified the Inaba's procedure by using delayed suture of the incision wound and omitting tie - over dressing. The comparative study of Inaba's procedure and its modification was performed to confirm the advantages of modified procedure. Methods: The study contains the retrospective analysis of the medical records of 296 patients with osmidrosis who were treated using the Inaba's procedure from December, 1996 to February, 2007. The study also contains the prospective analysis of 20 patients, from March, 2007 to July, 2008, who were treated by the modified Inaba's procedure with delayed suture of the incision wound and gentle pressure dressing instead of tie - over dressing. The operative results of two groups were compared and verified by Mann - Whitney U test(SPSS 12.0). Results: The incidence of complications was 14.5% in the Inaba's procedure, whereas 6.2% in the modified Inaba's procedure. Both procedures have the same basic surgical procedure in terms of the location of incision site and subdermal shaving of the sweat glands, and therefore similar good results were obtained in the aspect of postoperative axillary odor, recurrent rate and postoperative condition of axillary hair. Certainly, the modified Inaba's procedure had better outcome in each element of PSS(Patient Scar Self-Rating Scale), compared to the Inaba's procedure. In addition, the modified Inaba's procedure showed a statistical significance in dressing - related pain reduction and overall satisfaction. Conclusion: The modified Inaba's procedure had advantages of decreased early postoperative complications such as hematoma, discomfort and pain caused by tie - over dressing, and decreased scar formation. However, the drawback was delayed suture of the incision wound after 48 hours.

Lymphedema is a chronic disorder characterized by lymph stasis in the subcutaneous tissue. Lymphatic fluid contains several components including hyaluronic acid and has many important properties. Over the past few years, significant research has been performed to identify an ideal tissue to implant as a filler. Because of its unique composition, fat harvested from the lymphedema tissue is an interesting topic for investigation and has significant potential for application as a filler, particularly in facial rejuvenation. Over a 36-month period, we treated and assessed 8 patients with lymphedematous limbs who concurrently underwent facial rejuvenation with lymphedema fat (LF). We conducted a pre- and postoperative satisfaction questionnaire survey and a histological assessment of the harvested LF fat. The overall mean general appearance score at an average of 6 months after the procedure was $7.2{\pm}0.5$, demonstrating great improvement. Patients reported significant improvement in their skin texture with a reading of $8.5{\pm}0.7$ and an improvement in their self-esteem. This study demonstrates that LF as an ideal autologous injectable filler is clinically applicable and easily available in patients with lymphedema. We recommend the further study and clinical use of this tissue as it exhibits important properties and qualities for future applications and research.

Background Skin-sparing mastectomy with immediate breast reconstruction is increasingly becoming a proven surgical option for early-stage breast cancer patients. Areola-sparing mastectomy (ASM) has also recently become a popular procedure. The purpose of this article is to investigate the reconstructive and aesthetic issues experienced with one-stage nipple and breast reconstruction using ASM. Methods Among the patients who underwent mastectomy between March 2008 and March 2010, 5 women with a low probability of nipple-areolar complex malignant involvement underwent ASM and immediate breast reconstruction with simultaneous nipple reconstruction using the modified C-V flap. The cosmetic outcomes of this series were reviewed by plastic surgeons and patient self-assessment and satisfaction were assessed via telephone interview. Results During the average 11-month follow-up period, there were no cases of cancer recurrence, the aesthetic outcomes were graded as excellent to very good, and all of the patients were satisfied. Two patients developed a gutter-like depression around the reconstructed nipple, and one patient developed skin erosion in a small area of the areola, which healed with conservative dressing. The other complications, such as necrosis of the skin flap or areola, seroma, hematoma, or fat necrosis did not occur. Conclusions Since one-stage nipple and breast reconstruction following ASM is an oncologically safe, cost-effective, and aesthetically satisfactory procedure, it is a good surgical option for early breast cancer patients.

The purpose of this study is to design the compensation model by analyzing the compensation level for advanced science and technology manpower. The result of this study can be summarized as follows. First, advanced S&T manpower has preferred not only economic rewards, but also non-economic rewards which comprises both social reputation, self-satisfaction for job and other aspects of life. Second, the way of what high grade human resources in S&T have preferred to be rewarded differs among agencies. While professors in universities prefer research environment, researchers working for GRIs(Government-funded research institutes) want to have job stabilization and researchers in companies want to have higher monetary reward. Third, two main factors to change their occupation have been turned out to be monetary reward and social reputation. It means that the compensation system should satisfy what advanced S&T manpower at GRIs and companies need upgrading their social reputation.

Purpose: The aim of this study was to describe the status and associated factors of mental health on girls' high school students. Methods: The participants were 446 academic girls' high school students and 240 vocational girls' high school students of the 1st graders in Busan. The data were collected from April 28, 2009 to May 30, 2009. Survey was developed in the form of self-report five-point likert scale(1-5) using Lees Instrument of mental health(1986) that revised from Derogatis et al's Symptom Check List-90(1976). The higher score of this scale means worse status of mental health. Result: The score of mental health of subjects was low and the mean was $1.69{\pm}.50.$ The depression mean was the highest among mental health sub-variables. The mental health of the vocational girls' high school students was worse than the academics. As for subjects in mental health by their various characteristics, there are significant by school type(p<0.001), economic status(p<0.001), father's job(p<0.001), parent's marrital status(p<0.001), cognitive health status(p<0.001), record(p<0.05), character(p<0.001), satisfaction of life(p<0.001), needs for help on mental health(p<0.001). Conclusion: The intervention program needs to improve mental health of vocational high school girls' students as well as academic high school girls' students, and need to establish depression relieving nursing intervention program for girls' high school students.

The purposes of this study were to evaluate students' performance by student self-evaluation and by educators in the field respectively after an internship program, to analyze the gap between the two groups, to identify students, satisfaction and behavior intention and to suggest the direction of an internship program in the Food and Nutrition Department. The results of the survey of 133 students and 129 educators as follows: a majority of the program periods was two weeks and most students experienced an internship program once. Both students and educators evaluated highly in 'I (Students) worked faithfully as a trainee.', 'I (Students) observed the rules and cooperated with other colleagues.', 'I (Students) behaved with clear and polite words.'. Educators estimated higher than students in all items, especially in 'I (Students) prepared and planned needs for internship in advance.' (p<0.00l), 'I (Students) got on close terms with the staff and enjoyed their confidence.' (p<0.001). For details of the internship program, students were satisfied with 'professors' roles' (3.95), 'educator's abilities' (3.85), 'treatment of students' (3.84) but dissatisfied with 'pay to students' (1.94). Students perceived that an internship program was helpful to understand their major (4.37) and to decide upon their job (4.17). They had an intention to participate in another internship program (4.63) and to recommend to their juniors to participate in a program (4.73). Students had a diversity of opinions for program periods and most wanted to participate two times in summer or winter vacation of junior. Therefore an internship program needs curriculum in the food and nutrition department and the continuous and active cooperation between university and institutions would lead to an effective and efficient internship program.
