Hazardous chemicals, such as polycyclic aromatic hydrocarbons (PAHs), volatile organic compounds (VOCs) and heavy metals, are known as being harmful to human health were included in oils released by the Herbei Spirit Oil Spill accident in December 2007. To investigate changes of eating habits by the exposure to harmful substances, we conducted 5 focus group interviews for residents at Taean coast areas, who had experienced the oil spill accident. Participants included 46 women (mean age: $57.2{\pm}10.9$) who were mainly responsible for preparing family meals. Focus group discussions were audio-taped, transcribed and categorized by themes. Participants expressed more frequent illness symptoms such as dizziness, vomiting, visual loss, and skin diseases after the accident. They mentioned that their worries about economic hardship and worsened health status since the accident induced mental problems, such as depression about their children. Regarding eating habits, participants reported less intakes of fishes and meats and relatively more intakes of vegetables and kimchi due to the lack of household incomes after the accident. Although the participants had been used to collecting or catching fish or shellfish for their consumption previously, they mainly purchased these foods from local markets after the accident. Changes of eating habits induced by the accident included drinking boiled water and having steamed or fried seafood rather than raw seafood. Changes of food intakes occurred less frequently in older adults due to their longterm fixed eating habits, although they felt uncomfortable for having raw fish. The findings of this study clearly present that the exposure of hazardous substances by the oil spill accident had a significant impact on changes in eating habits besides economic, physical, and mental problems among the residents in Taean. Continuous health and nutrition monitoring and support are needed.

Purpose: The aim of this study was to evaluate the result of extraarticular dorsal closing wedge osteotomy in Freiberg's disease. Materials and Methods: Between February 2012 and July 2014, total 10 patients who underwent dorsal closing wedge osteotomy and followed up more than 1 year were selected for inclusion. Average age was 16.3 years, and average follow-up period was 15.5 months. The diagnosis was made using magnetic resonance imaging of those with a limitation in walking or usual activity due to pain in the metatarsal head. During operation, we removed loose body, and synovectomy was done. Osteotomy at the metatarsal neck and fixation with Kirschner wire were performed. X-ray was taken to check shortening of 2nd metatarsal and bone union. Moreover, we checked the active range of motion of 2nd metatarsophalangeal joint before and after surgery. At the last follow-up, the shortening of metatarsal, American Orthopaedic Foot and Ankle Society (AOFAS) score, visual analogue scale (VAS), and patient's subjective satisfaction were evaluated. Results: According to the Smillie's stage, there were 3 cases of stage II, 4 cases of stage III, and 3 cases of stage IV. Average bone union time on the osteotomy site was 8 weeks. Average shortening of metatarsal was 2.53 mm. Average AOFAS score improved significantly from 56.9 to 82.8 points at final follow-up (p<0.05), and average VAS score also improved significantly from 6.4 to 1.4 points at final follow-up (p<0.05). Average active range of motion at metatarsophalangeal joint improved from $28.0^{\circ}$ preoperatively to $46.5^{\circ}$ at the final follow-up. Other complications, such as metatarsalgia and arthritis, were not found; however, there was 1 case of delayed union with no symptom. Conclusion: In Freiberg's disease, dorsal closing wedge osteotomy is recommended for the improvement of clinical symptoms and range of motion.

Purpose: This study examined the clinical outcomes and assessed the average time to return to play following a peroneal tendon repair in Korean athletes. Materials and Methods: Between March 2004 and February 2017, a total of 30 athletes underwent peroneal tendon repair for a peroneal tendon tear. The indications of surgical treatment were chronic pain or intractable symptoms after a previous ankle sprain affecting sports activity refractory to conservative treatment for at least six months. The patient underwent tubulization for a longitudinal tendon rupture. Peroneus longus to peroneus brevis tenodesis was performed when tendon repair was impossible due to total rupture or multiple longitudinal rupture. Results: Twenty patients not included in this study were as follows: insufficient follow-up, previous surgery, and additional bone surgery. All 10 patients had a previous ankle sprain history, tenderness and swelling on the retromalleolar area. In the 10 patient population, there were five peroneus brevis tendon tears, three peroneus longus tendon tears, one peroneus longus and brevis tendon tear, and one peroneus brevis and superior peroneal retinaculum tear. In the 10 patients, six cases of peroneal brevis tendon repair and four cases of peroneal longus to brevis tenodesis were performed. The preoperative American Orthopaedic Foot and Ankle Society score was improved from a mean of 60.6 (standard deviation [SD], 8.64) to a mean of 90.2, postoperatively (SD, 4.4; p<0.012). The preoperative visual analogue scale was improved from a mean of 5.43 (SD, 1.2) to 0.5 (SD, 0.16), postoperatively (p<0.023). The mean length of time to return to play was 12.2 weeks (range, 8~16 weeks). Conclusion: Peroneal tendon tear can occur due to sports injuries. If there is tenderness at the retromalleolar area, the surgeon should consider a peroneal tendon lesion. Surgical repair of the peroneal tendon can be an effective treatment to help athletes to return to play.

Objectives : To propose the referential data to evaluate the health impacts of Vietnam veterans' children whose father were exposed to herbicides in Vietnam War. Methods : Vietnam veterans who visited to Pusan Veteran Hospital for medical care were recruited from April to October, 1998. They were 71 and asked about their own combat history, symptoms and illness, and health status of their 182 children. The informations were collected by direct and phone interview. Exposure estimation was also performed as exposure score depending on year and unit of participation, and personal episodes related to exposure to herbicide in the war. It classified into three groups; lower(<18.0), moderate(18-53), high$(\geq53)$ exposure group. Results : The mean age and the period into the combat of the veterans were 52.8 years and 15.0 months. The mean exposure score was $18.1{\pm}9.9$, and mainly distributed in lower (46.5%) and moderate(52.1%) exposure group. Most(90.1%) of them were diagnosed as sequelae(21 cases) and suspected sequelae(43 cases) of the herbicides by Korean veteran's hospital diagnostic criteria. The major sequelae was peripheral neuropathy 13 cases, chloracne 5 cases, and the major suspected sequelae was hypertension 20 cases, diabetes mellitus 18 cases, liver disease 12 cases, central neuropathy 11 cases, etc. About birth, 42.2% and 16.9% experienced spontaneous abortion and stillbirth, respectively. The mean exposure score was higher in stillbirth experience group(p<0.05). About half of the children(90 cases, 49.5%) hold the abnormal health status: those were skin pigmentation 38 cases, rash 23 cases, congenital anomaly 15 cases, general weakness 12 cases, purpura 8 cases, visual disturbance 8 cases, etc. These health problems had no association with father's exposure level(p>0.05). Conclusions : These results were depend on their own answers, and expectation for compensation did not excluded, therefore, this study may have limitations: inaccuracy of informations due to recall bias and response bias. Nevertheless, through this study, we could image the fundamental aspect for health impacts of Vietnam veterans' children for preparing the national control program and policy. A large scale epidemiologic study with valid exposure assessment on the health impacts of Vietnam veterans' children is recommneded.

국내의 여러 배추 생산지로부터 뿌리혹을 채집하여 단포자 균주(SSI)를 분리하였다. 분리한 단포자를 접종한 후 총 321개의 뿌리를 수거하여 병징 발현 여부를 관찰하였다. 접종한 개체 중 단 한 개체에서만 작은 혹이 형성되었고, 70개 개체에서 미약한 기형 증상을 보였다. 이들 이상 증상을 보인 개체를 마쇄하여 단포자 균주의 안정적 증식을 위한 접종원으로 사용하였다. 단포자를 접종하여 발병시킨 개체로부터 얻은 포자들을 재접종하였을 때가 1차 단포자 접종하였을 때보다 병징이 훨씬 확대되었고, 이후 실험에 사용할 수 있을 정도로 증식된 개체는 15균주였다. 이 15균주들을 Williams의 판별기주에 접종하여 분석하였을 때, race 1이 4균주, race 4는 7균주, race 9는 2균주, race 11이 2균주로 각각 판별되어, race 4가 국내에 가장 우점하는 것으로 밝혀졌다. 이들 race들은 모두 배추, 무, 순무에 단포자 접종하여 얻어진 균주들로, 병원성 검정에서도 4종의 판별품종 중 Rutabaga 계열(스페인산 순무)에 속하는 'Laurentian'과 'Wilhelmsburger' 두 품종에만 병원성을 보였다. 따라서 이 race들이 배추, 무, 순무에 대해 강한 병원성을 보이는 것으로 보아 국내의 P. brassicae 군집은 배추와 무, 순무 등에 강한 병원성을 나타내는 race가 우점하는 것으로 판단된다. 이는 이들 작물이 병 발생량에 따른 국내 십자화과 채소 감수 비율과도 연관이 있으리라 생각된다.

This study was aimed to identify the effect of abdominal moxibustion on premenstrual syndrome and dysmenorrhea in university students. The data were collected by using questionnaires from April 25, 2005 to June 20, 2005. The subjects were university students from in the Pusan metropolitan area who had complained of menstrual discomfort. Thirteen students were assigned to the experimental group and fourteen students to the control group. The research design of this study was a nonequivalent control group pretest-posttest design. In the research method pretest were conducted through measurement based on scores of general character, menstrual character, premenstrual syndrome and dysmenorrhea in the experimental group and the control group. Experimentation was conducted by abdominal moxibustion being applied on the kwan-won hole and Ki-hae hole for 25 minutes at a time, three times a week, form the ending of one menstrual cycle to the beginning of the next menstrual cycle were in the experimental group. After treatment was finished, post tests conducted through measurement based on scores of premenstrual syndrome and dysmenorrhea in the experimental group. The control group conducted a point of same time and same measurement with the experimental group. The instruments used in this study MDQ(Menstual Distress Questionnaire) developed by moos(1968) and the VAS(Visual Analogue Scale) developed by Cline(1992). The data were analysed by SPSS/ win 12.0 program with ${\chi}$2-test and t-test to verify identification among subjects' general characteristics and menstrual characteristics. Hypothesis verification was analysed with t-test. The results of the study are as follows: The hypothesis, 'the experimental group who received abdominal moxibustion will decrease premenstrual symptoms more than the control group', was supported (t= -2.121, p=.022). The hypothesis, 'the experimental group who received adbominal moxibustion will decrease dysmenorrhea compared to the control group', was supported (t=-4.424, p=.001). As a result of this study, abdominal moxibustion will be used as a nursing aide to improve and prevent menstrual discomfort of university students who have premenstrual syndrome and dysmenorrhea.

단감(Diospyros kaki) 저장시 문제되는 과정부 갈변은 품종마다 다른 양상을 보이고 있다. 따라서 본 연구는 단감품종의 일반적인 과실의 물성특성을 파악하고, 저장 100일 후에 각 품종의 과육갈변이 세포구조에 어떠한 영향을 미치는 지에 대해서 조사하였다. 단감 품종은 '부유'(Fuyu), '차랑'(Jiro), '상서조생'(Uenishiwase), '대안단감'(Daiandangam), '로-19'(Ro-19)이며 2003년 10월말에 수확해서 저장 100일 후에 조사하였다. 과실의 각 물성의 특성은 품종마다 다양하였고, '차랑'과 '로-19'는 갈변과가 관찰되지 않았고, '대안단감'의 경우 80%에 가까운 과육 갈변과가 나타났다. 과육 갈변과 발생이 많은 품종인 '부유', '상서조생', '대안단감'과, 과육 갈변과가 발생하지 않는 '차랑' 및 '로-19'와의 과피구조에는 차이가 없는 것으로 조사되었다. '차랑'은 과피층이 외표피층을 포함하여 1~2층으로 형성되어서 갈변이 유도될 만한 세포층 자체를 형성하지 못하는 것으로 보이며, '부유'는 과피층이 2~3층으로 갈변이 유도될 만한 세포층을 제공한 것으로 판단된다. 정상과와 갈변과의 전체적인 조직의 구조적인 차이는 발견되지 못하였으나, 갈변과의 경우 과육 내 소포 소기관이 구별이 되지 못했고, 세포벽의 분해가 진행되는 것으로 관찰되었다.

Objectives : The purpose of the research is to measure Dental Hygiene students' level of musculoskeletal pain before and after receiving scaling training which involves repetitive operations and examine effects the operations have on the students' grip and pinch strength. Methods : 15 subjects in Dental Hygiene at Y university located in Chungbuk were tested on November 2, 2011. Results : 12 students had a musculoskeletal pain before receiving scaling training. However, all the 15 students had a musculoskeletal pain after the training. Body part the largest number of the students complained of the pain on was shoulders(37.9%) followed by neck(20.8%), waist(13.9%), wrists(10.3%), then back(6.9%) before receiving the training. Then the result showed that shoulders are where the largest number of students(24.1%) felt the pain, followed by neck(17.2%), wrists and fingers(13.8%), waist(12.1%), back and lower arms(6.9%), then palms(5.2%) after the training. Visual Analogue Scale(VAS) increased to $6.35{\pm}2.09$ after receiving the training from $3.31{\pm}3.38$ and this shows statistically significant difference(p<.001). Upon inspection, average grip strength decreased to $23.23{\pm}5.79kg$ from $25.00{\pm}4.51kg$ after receiving the training and this shows statistically significant difference(p<.05). Key pinch was the strongest among the three pinch strengths followed by tripod pinch then tip pinch. Average of all the three pinch strengths showed to have statistically significant difference before and after the training(p<.05); Tip pinch from $6.53{\pm}1.36$ to $5.87{\pm}1.3$, key pinch from $13.47{\pm}2.5$ to $12.53{\pm}2.30$, and tripod pinch from $9.27{\pm}3.04$ to $8.03{\pm}2.72$. Conclusions : The result showed that scaling training has effects on Dental Hygiene students' musculoskeletal subjective symptoms and their grip and pinch strength changes after receiving the training.
