Purpose: The purpose of this study was to identify social support networks for each life-cycle stage of adults. Method: A total of 1,047 subjects included 454 young adults, 262 middle-aged adults and 331 senior adults. Data were collected using Oh’s Korean Version Norbeck’s Social Support Questionnaire (NSSQ), and analyzed using descriptive statistics, t-test, and ANOVA. Result: For the young adults, parents were the top and second priority as important social support resources, the third was siblings, and then friends. For the middle-aged, spouse was the first priority as an important social support resource, while the second and the third were children. For the senior adults, children ranked from the top to the seventh priority. The mean number of social support resources was 13.23 for the young adult, 12.93 for the middle-aged and 5.30 for the senior adults. Social support networks of the young adults significantly differed according to gender and marital status. That of the middle-aged significantly differed according to family size. In addition, that of the senior adults was significantly different according to marital status, economic status, religion and family size. Conclusion: It is essential to consider social support networks for each life-cycle stage of adults when making a social support intervention program.

A comparison of ozone simulations in the seoul metropolitan region (SMR) using the community multiscale air quality (CMAQ) model with SAPRC99 and CB05 chemical mechanisms (i.e. EXP-SP99 and EXP-CB05) has been conducted during four seasons of 2012. The model results showed that the differences in average ozone concentrations between the EXP-SP99 and EXP-CB05 were found to be large in summer, but very small in the other seasons. This can be attributed that the SAPRC99 tends to produce more ozone than the CB05 in urban area like the SMR with low VOC/NOx ratio under high ozone conditions. Through quantitative comparison between two mechanisms for the summer, it was found that the average ozone concentrations from the EXP-SP99 were about 3 ppb higher than those from the EXP-CB05 and agreed well with the observations. Horizontal differences in ozone concentrations between SAPRC99 and CB05 showed that significant differences were found in southern part of the SMR and over the sea near the coast in summer.

This paper aimed to verify the protective effects of Thuja orientalic extract against oxidative stress caused by H2O2 Rotenone and Paraquat in the keratinocyte(HaCaT cell) of human-derived normal skin for the development of safer health food or functional cosmetic materials. It has been reported that Thuja orientalic has antioxidant effects. In accordance with the cytotoxicity of Thuja orientalic extract against HaCaT cells using MTT, the appropriate concentration was less than 50㎍/mL. Thuja orientalic extract exhibited protective effects against H2O2, rotenone, and paraquat by 86.6%, 86.45%, and 60.24%, respectively, at the concentration of 50㎍/mL. Thuja orientalic extract has protective effects against all three artificial stresses, and more protective effects against H2O2 and rotenone. The analysis results indicated that Thuja orientalic extract had antioxidant effects that could offer protection to the cells from a variety of oxidative stresses. Accordingly, Thuja orientalic extract has a highly applicable value as a functional health food or cosmetic ingredient in the current times in which wellbeing is a priority.

<P><B>Abstract</B></P> <P>In order to evaluate the potential of oxy-combustion of inverse nonpremixed coflow flames using a clean fuel to improve the combustion and emission characteristics compared with the normal coflow flames using air, the fundamental properties of inverse nonpremixed pure oxygen (O<SUB>2</SUB>)/methane (CH<SUB>4</SUB>) coflow flames in a model combustor are experimentally investigated. The combustion stability (extinction) limits, structure and nitrogen oxide (NO<SUB>x</SUB>) emissions of the inverse coflow flames in the quartz-windowed combustion chamber with a single shear coaxial injector and a fully opened exhaust nozzle are measured using OH<SUP>∗</SUP> chemiluminescence, a schlieren imaging system and a gas analyzer. Results show four distinct stability regimes and limits: the attached flame regime, the near-blowout flame regime, blowout limits and blowoff limits. The direct flame and OH<SUP>∗</SUP> chemiluminescence images confirm the cooling effects of chamber walls that cause no steady liftoff flame and only the near-blowout flame. The extinction limits of the inverse CH<SUB>4</SUB>/O<SUB>2</SUB> coflow flames are extended compared with the normal CH<SUB>4</SUB>/air coflow flames and reasonable levels of NO<SUB>x</SUB> emissions are observed, which supports that oxy-combustion of the inverse nonpremixed coflow flames using the clean fuel is acceptable for practical application, providing a useful database for modeling the flames in the confined chamber.</P> <P><B>Highlights</B></P> <P> <UL> <LI> Extended stability limits of inverse nonpremixed O<SUB>2</SUB>/CH<SUB>4</SUB> coflow flames are found. </LI> <LI> Stable, attached flames and oscillating, near-blowout flames are observed. </LI> <LI> Direct flame and OH<SUP>∗</SUP> chemiluminescence images indicate no steady liftoff flame. </LI> <LI> Reasonable levels of NO<SUB>x</SUB> emissions are observed. </LI> <LI> Inverse nonpremixed O<SUB>2</SUB>/CH<SUB>4</SUB> coflow flames are acceptable for practical applications. </LI> </UL> </P>

When polester fibers are hydrolyxed in alkaline solution, they dissolve successively from their surface and change their dyeability. We examined the weight loss ofpolyester films treated with NaOH solution under various conditions and the equilibrium.amount of disperse dyes absorbed in films. An uptake of dyes on films treated withan alkaline solution has beer discussed in relat'on to the changes of weight loss of films. The changes of weight loss increased linearly on hydrolyzing time because ofdissolving uniformly froml their surface of films. However. in high concentrations ofalkaline solution, the changes of weight loss increased drastically owing to OH-attackedto the inner regions of films. The tensile strength of hydrolysed films decreased a sodden drop when the weightloss were low. But it decreased gently when weight loss were high. The dye uptake of hydrolyzed films increased a very small amount below 20% ofweight loss. However, it increased remarkably above 20% of weight loss.

최근 면역저하환자의 증가와 함에 국내에서도 점차 침습성, 파종성 Fusarium 감염증 보고가 증가하고 있다. Fusarium 감염은 아스페르길루스 감염과 유사한 임상양상을 보이지만 특징적인 피부병변을 동반하고 혈액배양에서 균이 분리되는 경우가 더 많다. 저자들은 급성 림프구성 백혈병으로 진단받고 치료중인 30세 남자 환자에서 중증의 호중구 감소 상태에서 비특이적인 피부병변을 동반한 파종성 Fusarium 혈류감염을 경험하였기에 국내 증례 고찰과 함께 보고하는 바이다. 환자의 초기 피부병변은 구진에서 시작하여 주로 소포성 병변과 일부 통증을 동반한 결절 등 여러 형태로 나타났고, Tzank 도말검사 양성으로 비정형 수두로 오인되었다. 이후 피부병변은 농포로 변하였고, 혈액배양 및 피부 조직검사에서 파종성 Fusarium 감염으로 진단받았다. 환자는 liposomal amphotericin B, voriconazole 병합요법과 G-CSF 투여, 과립구 수혈을 받았으나, 호중구 감소증에서 회복하지 못하고 급성 호흡곤란증후군과 다장기 기능부전으로 사망하였다. 본 증례는 파종성 Fusarium 감염의 경우에도 수두양 병변으로 비특이적인 양상으로 나타날 수 있으므로, 감별진단을 위해 적극적으로 혈액배양과 피부조직검사를 시행해야 함을 보여준다. Recently, we experienced a case of disseminated fusarial blood stream infection with varicelloid skin eruptions, who had suffered from persistent neutropenic fever after salvage chemotherapy for relapsed acute lymphocytic leukemia (ALL). Neutropenia continued in spite of G-CSF and granulocyte transfusion, and he failed to respond to conventional amphotericin B initially, and then liposomal amphotericin B and voriconazole combination therapy. Disseminated fusariosis can be diagnosed by blood cultures in 50% of patients and present skin lesions in more than 80% of patients. So, typical skin lesions are important clue to diagnose of the disseminated fusariosis. However, many skin lesions in immunocompromised hosts are due to various infectious and non-infectious causes. So, this case shows that it is important to obtain biopsy specimens of skin lesions for histopathologic examination, culture and staining. Here, we present our case with the review of the literatures reported in our country, so far.

Malignant fibrous histiocytoma rarely occurs in the jaws. Although the histogenesis of this tumor remains controversal, it is best regarded as a primitive and pleomorphic nature reflected by collagen production and occasional phagocytosis. It is common for metastatic foci to appear in lung and regional lymph node. There are variable treatments such as radiotherapy, surgical excision or combination, therapy of surgical excision, chemotherapy and radiotherapy. With the review of literatures, the authors report the clinical study of two cases of malignant fibrous histiocytoma of the jaw.

Estrogen이 가토의 이개변형에 미치는 영향

오경,김정희,김정태,김석권 大韓成形外科學會 1999 Archives of Plastic Surgery Vol.26 No.1

Congenital auricular deformities such as lop ear, cup ear, prominent ear, and Stahl's ear can be corrected nonsurgically in the early neonatal period(first week after birth) obtaining satisfactory results. Auricular cartilage consists of chondrocytes and intercellular materials that are mainly assembled from collagen, elastin, and a proteoglycan aggergate. Cartilageelasticity is dependent upon the concentration of the proteoglycan aggregate. Hyaluronic acid, which is a constituent of proteoglycan aggregate and is increased by estrogens, has an important play on disconnecting the proteoglycan aggregate. So the increased estrogen results in the lack of elasticity. The circulating levels of free estradiol are higher during the first 72 hours after birth and decreases thereafter, so the ear is soft and easily malleable in this early neonatal period. In this study, we have applied aluminium splint(90 degree-angulated, 180 degree-angulated, and rolled) on rabbit ear. All of the rabbit was divided into 3 groups containing 3 types of deformities. In group 1, estrogen was applied to the deformed ear with regional injection to the perichondrium of auricular cartilage. In group 2. estrogen was applied topically with ointment. In group 3, as control group, saline was injected to the perichondrium. Four weeks later, in group 2, the shape of the deformed rabbit ear was maintained, and did not return to its original shape even after splint removal. From these results, we concluded that estrogen ointment could be tried as adjunctive therapeutic modalities to the nonsurgical treatment of the congenital auricular deformities.

Objectives : Repetitive transcranial magnetic stimulation (rTMS) is a novel, noninvasive method of brain stimulation. Since conventional rTMS does not cause seizure, marked advantage over electroconvulsive therapy (ECT), rTMS can be used easily and widely. Once the effects of rTMS on cognitive function are elucidated, its application will be further extended. However, the effects of rTMS on cognitive function have not been well examined. This study aimed to evaluate the effect of low frequencyr TMS on visual short term memory. Methods : Forty normal healthy volunteers were randomly assigned to rTMS (n=20) or sham (n=20) groups. The rTMS group were again randomly divided into left prefrontal (n=10) and right prefrontal (n=10) groups. For each group rTMS was given at 1 Hz for 20 minutes with 100% of motor threshold. As a cognitive task, Corsi Block Tapping Test (CORSI) in the computerized Vienna Test System, which can assess visual short term memory, was performed before, during, and after the rTMS. Results : No significant difference was found in the visual short term memories between the rTMS and the sham groups before, during, or after 1 Hz rTMS, nor between the left and right prefrontal rTMS groups. Conclusion : This study demonstrates that rTMS, contrary to ECT, has no adverse visual short term memory effect when used as the standard treatment paradigm. Therefore, rTMS could be a new and safe treatment method in various neuropsychiathc fields without any interference of cognitive function.
