This study was intended to investigate changes in the physique and fitness by age in adolescence. For this purpose, it attempted to make the first measurement in June, 2001 and the second measurement in 2002 for a total of 15 persons(seven middle school students aged 13 to 14 years and 8 high school students aged 16 to 17 years) practicing Taekwondo at 'S' and 'C' Drill Centers located in South Kyungsang Province. Both measures were conducted over the 2-day period. An attempt was made to compare and analyze the growth rate of physique and fitness factors by age based on data from measurement. As a result, the following conclusion was drawn: First, it was found that there was a statistically significant difference in the change of height, weight and body fat percent before and after measurement in order to investigate the change of physique(P<.05). Among other things, it was found that there was a statistically significant difference in the change of height, weight between the period of middle school days(13 to 14 years old) and the period of high school days(16 to 17 years old)(P<.05). It was found that Taekwondo trainees grew more over the period of middle school days(13 to 14 years old) than over the period of high school days(16 to 17 years old). But it was found that there was not a statistically significant difference in body fat percent between both groups(P<.05). But body fat percent reduced over the period of middle school days{13 to 14 years old) but did remain almost unchanged. Second, an attempt was made to measure power(high jump test), agility(side step test), muscular endurance(sit-up) and cardiopulmonary endurance(1500-meter run) to investigate the change of physique. It was found that there was not a statistically significant difference in the change of power(high jump test) and muscular endurance(sit-up) before and after measurement(P<.05). But it was found that there was a statistically significant difference on agility(side-step test) and cardiopulmonary(1500-meter run)(P<.05). It was found that there was a statistically significant difference in agility(side-step test), muscular endurance(sit-up) and cardiopulmonary endurance(1500-meter run) except power(high jump test) between he period of middle school days(13 to 14 years old) and the period of high school days(16 to 17 years old)(P<.05). The high jump test was conducted to investigate the change of power. As a result, it was found that power increase the period of middle school days(13 to 14 years old), whereas it decrease over the period of high school days(16 to 17 years old). On the other hand, the side-step test was conducted to investigate the change of agility. It was found that agility increased in Tawekwondo trainees over both the period of middle school days(13 to 14 years old) and the period of high school daysd(16 to 17 years old), the latter of which it was more or less improved. This study conducted the sit-up test to investigate the change of muscular endurance and the 1500-meter run test to investigate the change of cardiopulmonary endurance. In case of the 1500-meter run, cardiopulmonary endurance decreased over the period of middle school days(13 to 14 years old) but increased over the period of high school days(16 to 17 years old).

Background and Purposes: Over the past three decades, numerous studies performed in Korea have reported that job stress is a determinant risk factor for chronic diseases and work disability. Every society has its own culture and occupational climate particular to their organizations, and hence experiences different occupational stress. An occupational stress measurement tool therefore needs to be developed to estimate it objectively. The purpose of this study is to develop and standardize the Korean Occupational Stress Scale (KOSS) which is considered to be unique and specific occupational stressors in Korean employees. Subjects and Methods: Data were obtained from the National Study for Development and Standardization of Occupational Stress (NSDSOS Project: 2002-2004). A total of 12,631 employees from a nationwide sample proportional to the Korean Standard Industrial Classification and the Korean Standard Occupational Classification were administered. The KOSS was developed for 2 years (2002-2004). In the first year, we collected 255 items from the most popular job stress measurement tools such as JCQ, ERI, NIOSH and OSI, and 44 items derived from the a qualitative study (depth interview). Forty-three items of KOSS, in the second year, were retained for use in the final version of the KOSS by using Delphi and factor analysis. Items were scored using conventional 1-2-3-4 Likert scores for the response categories. Results: We developed eight subscales by using factor analysis and validation process: physical environment (3 items), job demand (8 items), insufficient job control (5 items), interpersonal conflict (4 items), job insecurity (6 items), organizational system (7 items), lack of reward (6 items), and occupational climate (4 items). Together they explained 50.0% of total variance. Internal consistency alpha scores were ranged from 0.51 to 0.82. Twenty-four items of the short form of the KOSS (KOSS-SF) were also developed to estimate job stress in the work setting. Because the levels of the subscales of occupational stress were gender dependent, gender-specific standard norms for both the 43-item full version and the 24-item short form using a quartile for the subscales of KOSS were presented. Conclusion: The results of this study suggest that KOSS might be an appropriate measurement scale to estimate occupational stress of Korean employees. Further and more detailed study needs to be conducted to improve the validity of this scale.

Objective: To investigate skeletal and dental changes after application of a mandibular setback surgery-first orthodontic treatment approach in cases of skeletal Class III malocclusion. Methods: A retrospective study of 34 patients (23 men, 11 women; mean age, 26.2 ± 6.6 years) with skeletal Class III deformities, who underwent surgery-first orthodontic treatment, was conducted. Skeletal landmarks in the maxilla and mandible at three time points, pre-treatment (T0), immediate-postoperative (T1), and post-treatment (T2), were analyzed using cone-beam computed tomography (CBCT)-generated half-cephalograms. Results: The significant T0 to T1 mandibular changes occurred ?9.24 ± 3.97 mm horizontally. From T1 to T2, the mandible tended to move forward 1.22 ± 2.02 mm, while the condylar position (Cd to Po-perpendicular plane) shifted backward, and the coronoid process (Cp to FH plane) moved vertically. Between T1 and T2, the vertical dimension changed significantly (p < 0.05). Changes in the vertical dimension were significantly correlated to T1 to T2 changes in the Cd to Po-perpendicular plane (r = ?0.671, p = 0.034), and in the Cp to FH plane (r = 0.733, p = 0.016), as well as to T0 to T1 changes in the Cp to Poperpendicular plane (r = 0.758, p = 0.011). Conclusions: Greater alterations in the vertical dimension caused larger post-treatment (T2) stage skeletal changes. Studying the mandibular position in relation to the post-surgical vertical dimension emphasized the integral importance of vertical dimension control and proximal segment management to the success of surgery-first orthodontic treatment.

The purpose of this study is to assess the adherence to dietary intervention for prevention of coronary heart disease (CHD) in postmenopausal women by observing changes of antioxidant vitamins and fatty acid composition in dietary intake and seam level. The subjects with hypercholesterolemia (TC≥240mg/dl) were treated with one of hormone replacement therapy (HRT group), dietary intervention (DIET group) or combination of hormone replacement therapy and dietary intervention (HRT+DIET group) for 12 weeks. The results were as followed. Mean daily nutrient intakes were not significantly changed in the HRT group, but were significantly changed in the DIET group and the HRT+DIET group. Especially, dietary vitamin A and E intakes were increased from less than 75% to more than 90% of RDA for Korean in the two groups. With changes of dietary intakes, serum vitamin A and E levels were also significantly increased in the DIET group and tended to increase in the HRT+DIET group. Dietary fatty acid composition was also not significantly changed in the HRT group, but was significantly chanced in the DIET group and the HRT+DIET group. With changes of dietary fatty acid composition, serum phospholipid fatty acid composition was significantly changed in the DIET group and the HRT+DIET group although there was tendency of returning to initial value after 12 weeks. Judging from changes in serum phospholipid fatty acid composition, subjects' adherence to dietary intervention tended to decrease after 12 weeks. However, the changes of antioxidant vitamins and fatty acid composition in dietary intake were compatible with the changes of those in serum level, and we can conclude that dietary intervention was adhered quite well by subjects.

Background: Hormone therapy, which includes tamoxifen and aromatase inhibitors, is the most common adjuvant therapy used for breast cancer. However, only a few studies have reported endocrine therapy induced alopecia. Objective: We investigated the effects of long-term adjuvant hormone therapy on hair in patients with breast cancer, in addition to patients’ concerns and current treatment for hair loss. Methods: Patients completed a questionnaire that included information on self-perceived hair changes after each adjuvant therapy session, distress, and current treatment for hair loss. Using a folliscope, we measured hair density and thickness in each patient and in healthy controls. Results: The study included 93 patients with breast cancer (mean age 51.9±9.8 years). The density and hair thickness were 106.36±21.85 hairs/cm2 and 0.07±0.01 mm in the patient group and 147.86±30.67 hairs/cm2 and 0.07±0.01 mm in the control group (n=98, mean age 52.10±8.40 years), respectively. The mean hair density was significantly lower in the patient group than in the control group; however, no statistically significant intergroup difference was observed in hair thickness. Among 76 patients who perceived hair changes after adjuvant therapy, 71.1% (n=54) were distressed with regard to hair changes. However, only 7.8% of the patients, including two who were treated by dermatologists, currently received treatment for hair changes. Conclusion: Dermatologists should be familiar with hair changes in patients with breast cancer and provide appropriate education to encourage patients to consult dermatologists for hair loss and thinning after breast cancer treatment.

This research has been designed as the second-year project of the four-year Special Research (2011-2014) effort. The main purpose of this current project is to develop potential scenarios regarding families of the future by predicting directions of change. In order to elaborate these scenarios, the five areas of demographic environment, labor and economic environment, science and technology, political environment, and perceptions of the family were singled out as major areas affecting the outlook on the future family. Next, the Delphi technique was applied in order to identify key drivers behind future changes in the family for each respective area. Next, the trend in changes was forecasted for each area and hypotheses were crafted regarding the impact of these changes on the lives of women and their families. Caretaking, inequality, and family values were selected as the main axes of the scenarios, based on a combination of the hypotheses. Next, the three axes were juxtaposed, resulting in a total of eight scenarios from which five were selected. These five scenarios include the conflict between personal values and family life scenario, the polarization of family life scenario, the loose but intimate family scenario, the coexistence of equal society and unequal family scenario, and the maximized familial burden scenario. According to a nation-wide survey of 5,000 people regarding these five scenarios, the loose but intimate family scenario was identified as the most preferred. In order for South Korea to progress toward this scenario, this research suggests reinforcement of social security policy, evaluation of overall care policy and future directions, and refinement of laws and institutions in accordance with the strengthening perception of an individual-oriented family.

Background: Epidermal cysts (EC) are the most common tumors found on the skin and accompanying inflammation is also frequent. However, the predictors for inflammatory change have not been investigated yet. Objectives: This study was performed to investigate the difference between inflamed and uninflamed epidermal cysts, and to assess associated factors for inflammatory change. Methods: We analyzed the biopsy-proven 1723 epidermal cysts (515 inflamed and 1208 uninflamed) at two tertiary hospitals from 2011 to 2021. Results: The proportion of inflamed epidermal cysts (IEC) and uninflamed epidermal cyst (UIEC) were 29.9 % and 70.1 %, respectively. Inflammatory change was less frequently observed on the face (25.5 %) than the other sites (32.1 %) (p=0.0046). The anatomic location with the highest rate of inflammatory change was back (40.8 %, p=0.0004). Mean duration of inflammatory change from UIEC to IEC on the face was shorter than the other sites (12.5 months vs 17.9 months, respectively, p= 0.0473). On ultrasonography, long axis of IEC (20.7mm) was generally longer than that of UIEC (15.7mm) (p=0.0218). Moreover, Inflammatory change was more frequent on the EC with punctum compared to those without punctum (35.3 % vs 30.3 %, P=0.0471). Conclusion: Based on the location, size and presence of punctum, decision on the optimal treatment strategies can be established when encountering patients with EC.

Hyun Soo Kim, Jong Woon Cheon, Min Su Kim, Chang Kil Jung, Kyung Rok Kim, Jae Won Choi, Dong Woo Kang and Sun Young Kim1 Departments of Internal Medicine and Pathology1, DongKang Medical Center, Ulsan, Korea Actinomycosis is a chronic suppurative disease and caused by Actinomycosis species, principally Actinomyces israelii, which are part of the normal inhabitant on the mucous membrane of the oropharynx, gastrointestinal tract, and urogenital tract. It usually affects cervicofacial, thoracic and abdominal tissue. Cervicofacial type has the highest percentage of occurrence with 50%. Actinomycosis frequently occurs following dental extraction, jaw surgery, chronic infection or poor oral hygiene. It may also be considered as an opportunistic infection in immunocompromised patients such as malignancy, human immunodeficiency virus infection, diabetes mellitus, steroid usage or alcoholism. But, actinomycosis rarely occurs in adults with normal immunity and rare in the esophagus. We report an unusual case of esophageal actinomycosis which was developed in a patient with normal immunity and improved by therapy with intravenous penicillin G followed oral amoxicillin, and we also reviewed the associated literature.
