  • The objectives of this study are to identify health behaviors and health problems. and the relations between health behaviors and health problems of female workers in the retail business. The number of subjects were 200 female workers of 6 department stores in Seoul and Kyonggi area, whose jobs last more than 6 months as retail employees. The data was collected during 2 months from July 1 to August 30, 1998. The Cornell Medical Index Health Questionnaire(CMI) was used to measure their health problems, while health behaViorn were investigated in terms of 'smoking', 'alcohol', exercise', 'diet', and 'sleeping'. The data were analyzed with frequency. percentage, t-test, ANOVA test, and $X^2-test$ by SPSS PC+ program. The results of this study are as follows: 1. Out of health problems. Digestive symptoms occupied the highest percent number. nervous ones the second and cardiovascular ones the third among physical health problems of retail female workers. The most frequent mental health problem was 'adequacy' and the next, 'tension' and 'anger', 2, Health problems according to general characteristics of subjects were shown that the younger or the unmarried complained more than the older or the married, especially in the items of 'eye and ear', 'respiratory system', 'cardiovascular system', 'digestive tract', 'nervous system', 'adequacy', and 'depression'. The longer working duration they have had, the more they complained of 'respiratory system' and 'adequacy'. The lower academic careers complained of 'nervous' than the higher ones with statistical significance. 3. The analysis of daily health clinic notes showed that respiratory complaints were the highest percent, successively followed by digestive tract, nervous one, external injury, musculoskeletal system, urinary-reproductive system and others. 4. The level of their health practice was generally low in smoking, diet habit and alcohol intake, exercise, sleeping, very low especially in smoking, diet, alcohol intake, and exercise among them all. 5. Present smokers and ones with past experience complained of physical and mental health problems of 'respiratory system', 'digestive tract', 'skin', 'nervous', 'urinary-reproductive system', 'fatigability', adequacy', 'depression', 'anxiety', 'anger' and 'tension', than non smokers, with statistical difference. Workers without having breakfast and with irregular diet had more complaints on 'digestive tract', 'adequacy' and 'tension', than those who had regular dietary habit. The less the subjects slept, the more they complained of eye and ear, cardiovascular system. The subjects who drank alcohol complained more digestive problem. However, whether they exercise or not did not affect physical and mental health problems in a significant manner. 6. The subjects' age and marital status were statistically significant relating to health behaviors, as the younger or unmarried recorded a low level of health practice in smoking, drinking, dietary habit. Based on the results, the suggestions are made as follows: 1. Health education program on smoking, alcohol intake, diet habit is needed to improve health problems and health behavior of female retail workers. 2. The unmarried workers of late teen and twenties, who are transitional period from teenagers to adulthood are important targets for health promotion program especially for maternal health. 3. Better working environment with sufficient time and facilities for workers to relax is required to promote female sales workers' health. 4. Further research is required to identify the relation between workers' visual fatigue and intense lights for the display of goods.

  • 이 연구는 개의 귀 속에서 분리한 $Malassezia$ $pachydermatis$의 특성과 이들 효모에 대한 essential oil들의 항진균효과를 측정한 결과로서 일반적인 $M.$ $pachydermatis$를 분리하기위한 Sabouraud dextrose agar (SDA), olive oil이 첨가된 SDA (SDAO) 배지 및 지방 친화성 효모를 검출하기 위한 Leeming's medium (LM)으로 구성된 세종류의 분리배지가 사용되었다. $Malassezia$ spp는 77.8%의 개로부터 분리되었으며 분리배지에 따라 분리율에 큰 차이를 나타내었으며 지방성분이 포함된 배지에서의 분리율이 일반적으로 사용하는 SDA에서 보다 높았다. 분리된 모든 $Malassezia$ spp는 $M.$ $pachydermatis$로 동정되었지만 육안적으로 보이는 집락의 모양과 SDA에서의 증식속도를 고려했을 때 4개의 아종으로 관찰되었다. 배양 72시간 후 집락의 직경이 3 mm 이상인 큰 집락(LC)과 2 mm 정도인 중간 집락(MC) 및 배양 5일 후에도 1 mm 이상으로 크지지 않는 작은 집락(SC), 그리고 SDA에서 증식하지 않는 지방의존 집락(Lipo)으로 분류되었다. SDA, SDAO 및 LM 배지에서 각 type의 효모가 분리된 정도를 보면, LC type 효모는 각각 4, 11, 11개 시료에서, MC type 효모는 각각 2, 3, 1개 시료에서, SC type 효모는 각각 1, 2, 1개시료에서 분리되었으며 Lipo type은 SDAO과 LM 배지 중 3 곳에서 분리되었다. $M.$ $pachydermatis$에 대한 essential oil의 항진균효과 측정은 디스크 확산법과 well 확산법에 의해 이루어졌으며, 대부분의 essential oil은 0.5에서 1.0%의 농도에서 $M.$ $pachydermatis$ 의 증식을 억제하였다. MIC90과 MIC50은 essential oil의 성분에 따라 다양하였으나, Thyme oil이 가장 억제 효과가 좋았으며 marjoram과 tea tree oil은 비교적 낮은 억제 능력을 나타내었다.

  • Objectives: Galgeunhaegitang-gamibang(GH) and Samhwangseze-gamibang(SG) has been known that they are helpful for treatment of atopic dermititis clinically, but there is no report about the effect of GH and SG. So, author aimed to investigate the effects of GH and SG on atopic dermititis of NC/Nga mice. Methods : NC/Nga mice were divide into three group : normal, control, and experimental group. Atopic dermatitis was induced in the control and experimental group by spreading DNCB. Then GH was orally administered three times in a week for 8 weeks to the experimental group and SG was spreaded two times in a day for 8 weeks to the experimental group, while the control group was given normal saline. We observed changes of clinical skin severity score, serum IgE, IL-4, IL-4, IL-5, IL-6, IgM, IgGl, $IFN-{\gamma}$ and so on. We used one-way ANOVA test statistically(p<0.01). Results : Clinical skin severities of experiment group in 13 and 16weeks were significantly decreased by 48% and 55% compared to the control group. Serum IgE, IL-4, IL-5, IL-6, IgM, IgGl levels of experimental group were singnificantly decreased compared to the control group. Serum $IFN-{\gamma}$ level of the experimental group was significantly increased against control group. mRNA expression levels of IL-4, IL-5, IL-6 and CCR3 in the skin tissues of experimental group were significantly decreased compared to the control group. In contrary, $IFN-{\gamma}$y mRNA expression level were increased compared to the control group. Histological observation of the ear and skin tissues showed that the extents of inflammation and infiltrated immune cells in the epidermis and dermis of experimental group were highly deminished compared to the control group. Judging from that $IL-1{\beta}$, $TNF-{\alpha}$, IL-6 expression of gene, the effects of inflammatory cytokine revelation were significantly decreased compared to the control group. In the model inducing COX-2 activity in RAW 264.7 cell, COX-2 activity was significantly inhibited depending on the density of GH compared to the control serum. According to cell multiplication, examination of cell toxicity showed that GH is safe at the density of 10, 50, 100mg/l and even 1000mg/l. Conclusion : Accordin to the above results, it is considered that GH and SG is effective treatment for the atopic dermatitis.

  • Purpose: This study was aimed to examine the resorption rate, the healing pattern, and the response of the surrounding tissue after the graft of the acellular dermal matrix ($AlloDerm^{(R)}$) and the autogenous dermis, and to report the clinical result of the use of $AlloDerm^{(R)}$ in order to restore the soft tissue defects. Methods: Twenty mature rabbits, weighing about 3 ㎏, were used for the experimental study. The $10\times10$ mm-size autogenous dermis and the $AlloDerm^{(R)}$ were grafted to the space between the external abdominal oblique muscle and the fascia of the rabbits. And the $AlloDerm^{(R)}$ was grafted to the pocket between the skin and the underlying perichondrium of rabbit ear. The resorption rate of the grafted sites was calculated, and the tissue specimens were histologically examined at 1, 2, 4, and 8 weeks after the graft. The five patients with the cleft-lip nasal deformity and the one patient with the saddle nose deformity, who received the $AlloDerm^{(R)}$ graft to restore the facial soft tissue defects, were reviewed for the clinical study. Results: The resorption rate at 8 weeks after the graft was 21.5% for the autogenous dermis, and 16.0% $AlloDerm^{(R)}$. In microscopic examinations, the infiltration of the inflammatory cells and the epidermal inclusion cyst were observed in the autogenous dermis graft. However, the neovascularization and the progressive growth of the new fibroblasts were shown in the $AlloDerm^{(R)}$ graft. And the six patients, who received the $AlloDerm^{(R)}$ graft, demonstrated the good stability of the grafts and improved appearance. There were no remarkable complications such as inflammation, rejection, dislocation, and severe absorption in the clinical cases. Conclusion: These results suggest that $AlloDerm^{(R)}$ can be an useful graft material for restoration of soft tissue defects because of the good stability and the tissue response without the remarkable clinical complications.

  • This investigation was conducted on 249 Jindo dogs aging from 2 to 12 months to determine body type and external appearance of the dogs. The results of this investigation were as follows. 1. The withers height of male dogs growed rapidly during the period between 2 months and 7 months of age, and was 22.94cm and 49.77cm, respectively. Afterward the growth rate slowed down up to 12 months, 53.33cm. The growth rate of female was similar to male, and the withers height was 22.91cm, 46.81cm, 48.70cm at 2, 6 and 12 months of age. 2. For male and female the body length was 27.21, 27.23cm at 2 months, 51.40cm, 51.62cm at 6 months, 58.33, 52.15cm at 12 months, respectively. Growth rate of the body length was very rapid from 2 to 6 months of age, but afterwards the growth rate was slow and somewhat retarded. 3. For male and female, the withers height to body length ratio was 100 : 109.4 and 100 : 107.1 in 12 months old group. 4. Cross over between the sexes in growth rate occurred between 5.3 to 6.5 months of age for wither height, between 6.0 to 7.2 months for hody length, respectively. 5. The average chest girths of male and female were 31.46, 30.46cm at 2 months, 54.92, 52.20cm at 7months, 60.25, 57.90cm at 12months, respectively. The growth rate of chest girth was rapid between 2 to 7 months of age and gradual between 7 to 12 months. 6. The average skull lengths of male and female were 11.76, 11.32cm at 2 months, 21.83, 19.60cm at 12 months, respectively. The average head widths of male and female were 8.37, 7.94cm at 2 months, 15.47, 12.46cm at 12 months. 7. Erected type of ear was completed from oblique type at 6 months in male and 7 months in female.

  • Woman in Choson era had various kind of accdssories like rings, ear ring, ornamentak hairpins and so on. Among them their favorite was the Norigae, the pendent trinket. With the embroidered ornament at its center, beads and knots were attached to the upper and lower part, and it was hung with a tassel. It was carried on the string of the Chogori. norigae oreginated in waist string of Three Countries era(Sills, Paekje and Koguryo) ; had been changed with the development of fashion, embroidery and the influence of Buddhistic culture. The differences between Embroidered Norigae and Norigae are following. If the ornament at its center is made of such jewels as gold, silver, jade and the like, it is called Norigae. But if the ornament at its center is made of the embroidered Norigae. Such a Embroidered Norigae in which perfume was contained, was as a perfume box or a perfume bag and was carried on the strings of Chogori by Danjak(single work). The Differences between ancient Embroidered Norigae of late Choson era and modern Embroidered Norigae are Following; 1) The type of main body-the embroidered ornament at its center was mainly embroidered with the shape of animals in both of ancient Embroidered Norigae was usually formes like a bat and that of modern Embroidered Norigae like butterfly. 2) plants were adapted as the main design of ancient Embroidered Norigae, but plants and animals as that of modern Embroidered Norigae. 3) The colors of the background and the design are usually red in both ancient and modern Embroidered norigae. 4) The tassels of ancient Embroidered Norigae were mode in the shape of srick and a strawberry. but the tassels of modern Embroidered Norigae were mainly made in the shape of a stick. 5) Nowadays the beauty of external form is considered more important while the symbol of main body was considered more important in Choson era. 6) The role of Thidon in the composition of Embroidered Norigae is declined and a lot of main bodies are used in modern Embroidered Norigae. 7) Modern Korean people are apt to choose Embroidered Norigae depending upon the design of main body and the traditional Korean beauty. 8) Modern people who desire to get new thing, try to make the design of main body various. As their cognition of Korean tradition is of the increase, the restoration of ancient Embroidered Norigae to its original form has been accom

  • Objectives : The aim of this review is to investigate studies on skin adverse reactions and to demonstrate subjects related to the adverse effects in dermatology. Methods : Electric searches were performed with KISS(Korean studies Information Search System) and the key words were combination of 'skin' and 'adverse effect'. 87 literatures investigated in this review were issued from 1900 to 2016. Results : Among the 87 papers, dermatologic adverse reactions were reported in 83 papers in medicine, accounting for 95.4%. Of the adverse effects seen on the skin, 84 discoloration such as erythema, pigmentation and hemotelangiosis were the most common, accounting for 21%. Among the medical adverse reactions not seen on the skin, 21 infection were the most common, accounting for 25%. Among the subjective adverse reactions, of which 32 pruritus were the most common, accounting for 43%. Among the 87 papers, there were 3 cases with underlying diabetes and 3 cases with underlying hypertension, followed by 2 cases with chronic renal failure, HBV, atopic dermatitis and respectively 1 case with alcoholism, depression addiction, multiple myeloma, arthritis and psoriasis. The most frequent period until adverse reactions appeared was within 2 weeks, accounting for 13 papers. And 4 were the most frequent adverse reactions lasting less than 1 month, and 4 were more than 3 months and less than 6 months. There were 48 cases where adverse reactions were caused by nonmedical practioner's treatment. The adverse reactions by the pharmacist were the highest at 11 cases (23%). There were 17 cases of adverse reactions due to medical treatment, among which dermatologists and nondermatologists accounted for the majority of 5 cases, 29%. The most common cause of adverse reactions was the application of external medicine (41 cases), followed by 36 cases of foreign body implantation, eyebrow tattooing, ear piercing, etc. Conclusions : In this report, we demonstrated patterns of adverse reactions in the medical field of dermatology caused by non-medical personnel than medical personnel. We suggest that more effort should be followed by medical personnel to establish clear awareness of skin disease and by patients to be aware of the risks of the illegal medical treatment by non-medical personnel.
