Objective : The aim of this study was to investigate fatigue-related factors including socio-demographic variables and life styles among workers in the automobile manufacturing industry. Method : The subjects were 22,937 individuals who had received health examination by Korean Medical doctors and responded to questionnaires for 8 months from March to November in 2011. The fatigue index was measured by heart rate variability (HRV) in an automobile manufacturing industry. A multivariate analysis with SPSS version 19.0 was used to examine the relationship between fatigue and other factors including ages, smoke consumption, drinking frequency, exercise frequency, occupational category, conjugal condition. Results : In comparison between normal and very bad level of fatigue, factors of ages, smoking, drinking, and exercise showed significant difference(p<0.05). In addition, when normal and bad fatigue were compared, ages, smoking, exercise also produced significant difference(p<0.05). Furthermore, in normal and good level of fatigue comparison, occupation and smoking yielded significant difference(p<0.05). Finally, in other comparisons between normal and very good fatigue, exercise, smoking and occupation revealed significant difference(p<0.05). Conclusion : The results of this study suggest that age increase affects fatigue negatively, whereas exercise and drinking of once or twice per a week can have positive correlations.

정현정,김지환,이상휘,박영범,Jung, Hyun Jung,Kim, Jee Hwan,Lee, Sang-Hwy,Park, Young-Bum 대한치과보철학회 2016 대한치과보철학회지 Vol.54 No.3

최근에 열가소성 레진 클라스프를 이용한 가철성 장치의 사용이 빈번해졌다. 통상적으로 사용하는 아크릴릭 레진과 비교했을 때 열가소성 레진은 낮은 굴곡 강도와 탄성률을 가지고 있다. 그러므로 열가소성 레진으로 제작된 가철성 장치는 파절의 위험이 낮아 의치상이 얇고 가볍게 만들어져 환자들이 편하게 사용할 수 있다. 또한 장치가 치아 언더컷에 수동적으로 장착될 수 있어 지대치의 삭제가 최소이거나 거의 없다. 이 증례에서는 경도의 구개인두부전을 가진 44세 여환은 polyester 계열 열가소성 레진으로 제작된 구개거상장치로 치료를 받았다. 환자가 결손치가 없고 보존적인 치료를 원하기 때문에 열가소성 레진을 이용한 가철성 장치가 상대적으로 만족스러운 치료 결과를 보였다. Recently, flexible removable prosthesis with thermoplastic resin clasp has increasingly become popular. In comparison with conventionally used acrylic resin, thermoplastic resin has lower flexural strength and elastic modulus. Thus, flexible removable prosthesis has low risk of fracture, so denture base can be made thin and light, increasing patient comfort. Also, it can passively sit at tooth undercut during rest, so abutment teeth need minimum or no preparation. In this case report, a 44 year old female patient with mild velopharyngeal insufficiency was treated with a palatal lift prosthesis made of polyester thermoplastic resin. Since the patient had no missing tooth and desired conservative treatment, the flexible removable prosthesis provided relatively satisfactory results.

정현정,양이슬,남진호,남기준,김동욱,Jung, Hyun-Jung,Yang, Yi-Seul,Nam, Jin-Ho,Nam, Gi-Joon,Kim, Dong-Wook 한국전기전자재료학회 2019 전기전자재료학회논문지 Vol.32 No.5

In this study, the volume resistivity of XLPE materials with various voltage ratings was discussed. The volume resistivity of the developed XPLE nanocomposite was measured, and the conductivity mechanism of the material was also examined. The ASTM D 257 and IEC 60093 measurement methods were used for these tests. The equipment was designed to measure up to a temperature of $200^{\circ}C$, and the electrode structure was designed to maintain the thickness and temperature uniformity of the sample. The conductivity of the sample decreased with temperature, and the samples reached saturation within 500s, after which the conductivity leveled off. By analyzing the current density and the electric field, we can well explain the electric conductivity behavior of our sample with the Schottky mechanism.

Eczema is a general term for skin diseases showing itching, vessiculopapular eruption, and erythema when acute, or lichenification and scale if chronic. It is classified as irritant dermatitis, atopic dermatitis, seborrheic dermatitis, neurodermatitis, nummular eczema, statis dermatitis, infective dermatitis, xerotic eczema, and pompholyx by afflicted regions and symptoms. Therapy for eczema is allopathic, and includes application of ice- pack to erythema, and application of emollients and steroids to the affected parts during subacute or chronic stages. Eczema is understood as ulceration(瘡), tinea(癬), wind syndrome(風證), and dryness syndrome(燥證) in terms of oriental medicine. Xerotic eczema is understood in dryness syndrome. Nourishing blood(養血) therapy is used. This is a case study on which xerotic eczema occurred on a patient's afflicted left palm and fingers after stroke. The patient's xerotic eczema was attributed to dryness syndrome. Therefore, Samul-tang(四物湯) and Saenghyeoryunbu-eum(生血潤膚飮) were used for nourishing blood. This therapy was effective on eczema and accompanying symptoms such as dizziness and numbness of the left hand.

The incidence rate of cervical cancer in Korea is still higher than in other developed countries, notwithstanding the national mass screening program. Cervical cancer prognosis is good due to an effective treatment such as surgery or radiation therapy, concurrent chemotherapy in the early stage. However, it is still a poor prognosis when advanced stage or recurrent. Some studies said that combined oriental and western medicine can improve the survival, quality of life, immune function, and decrease side effects in cervical cancer. In the western medical part, clinical practice guideline was published in 2006, 2007 and 2010 in Korea. In China, oriental medicine clinical practice guideline have been published in 2014. But there is no Korean medicine clinical practice guideline. This study will introduce the methods of diagnosis and the medical therapeutics which is commonly utilized for cervical cancer in Korea, and existing Korean medicine clinical practice guideline for Disease Analysis and Treatment (辨證論治). This study will be a meaningful study to establish clinical practice guidelines of Korean Medicine for cervical cancer.

정현정,권훈정 ( Hyun Jung Chung,Hoon Jeong Kwon ) 한국식품조리과학회 1997 한국식품조리과학회지 Vol.13 No.2

Ethyl carbamate is an animal carcinogen and a by-product of fermentation. Since the highest level of ethyl carbamate was found in a traditional soy sauce sample in the previous study, soysauce was prepared in varying experimental conditions with three kinds of meju originated from different area of the country to investigate the factors affecting ethyl carbamate formation. The sample analysis methods included a semi-purification with solid-phase extraction and detection by GC-MS at SIM mode using m/z 62 fragmention. Among the investigated factors, which includes source meju, brining length, salt content, irradiation of visible light during brining or storage, and storage length, source meju and storage length showed most profound effect on the formation of ethyl carbamate. Irradiation of visible light for 12 hours a day during storage lowered the concentration of ethyl carbamate compared to the soysauce kept in the dark. Meanwhile irradiation during the brining as well as the degree of salt contents showed no effect.
