  • Design of general steel structure had applied and achieve elastic design concept mainly so far. Because elastic design supposes that whole structure complies with elasticity formula as that achieve via allowable stress of material is concept that calculate stress distribution of construction about action external load and estimate load of when the maximum stress reaches equally with allowable stress that is established beforehand by maximum safety load of the structure. But, absence that compose actuality structure by deal with external load increase small success surrender and structure hardness falls and tell structure in limit state finally on the whole as showing complicated conduct by interference between these breakdown at buckling by compression. Examined closely about conduct of place since initial buckling through carbon vocal cords transformation finite element analysis series (ANSYS) that place mending condition supposes case that is boundary condition in this investigation.

  • 낙동강 하구의 지형변화 메커니즘을 파악하는 것은 하구의 관리방안과 처리방법 연구에 매우 중요하다. 본 연구에서는 낙동강 하구의 지형변화에 관여하는 강우, 하천유량, 유사량과 같은 육역으로부터 영향과 조석, 조류, 파랑, 표층퇴적물 등과 같은 해역으로부터의 영향을 조사 분석하였다. 분석된 자료에 근거하여 지형변화 실험을 수행하고, 지형변화와 외력조건별 기여도를 분석하였다. 수치실험 결과 지형변화는 하굿둑 방류 영향을 직접적으로 받는 수로부를 중심으로 침식이, 간접 영향권인 간석지를 중심으로 퇴적이 우세하게 나타났다. 수로부를 따라 이동되는 퇴적물이 파랑에 의해 분급, 배분되면서 울타리선 전면부에는 퇴적이 우세하였다. 지형변화 실험결과인 퇴적 우세현상과 비교하여, 외력조건별로 침식의 기여도가 크게 나타나고 있으나 각 외력조건의 복합적인 영향은 퇴적이 우세하게 나타나고 있다. 따라서, 낙동강 하구의 지형변화는 여러 복합적인 외력인자의 결과로 판단된다. 또한, 각 외력조건별 영향은 구역별로 상이한 기여도를 보이므로 하구관리방안 수립시 이러한 결과를 고려해야 하고, 반드시 복합적인 상호작용의 결과로 이해하고 있어야 할 것으로 사료된다.

  • The purpose of the present study was to examine the desire of married women to be re-employed and the factors related to this desire. The study gathered information from 240 women who gave up their jobs and careers after marriage. Information included their career history, current psycho-social condition, and family situation. Multiple regression and covariation structure analyses indicated that the desire of married women to go back to paid work was influenced by family economic condition, psycho-social condition, and child care situation. Specifically, the study found that family's monthly income and the age of the last child were negatively related to the women's desire for re-employment. On the other hand, economic pressure and achievement motivation were positively related to the women's desire. Finally, the study found that socio-economic background and external social support were not significantly related to the women’s wish to go back to the workforce.

Using external medical treatment for Leucorrhea is washing and fumigation on vagina, to wash vagina, to insert vagina, cleansing theraphy and use with Suppository such as YONGYEOMGO(龍鹽膏), KAMISASANGJASAN(加味蛇床子散), SASANGSACHUNGSEJE(蛇床子洗劑). 3. ANGELICAE GIGANTIS RADIX (當歸) is in mostly general use for external medical treatment of Menorrhalgia and Leucorrhea, in that order ANSU SEMEN(杏仁), EVODIAE FRUCTUS(吳茱萸), TORILIS FRUCTUS (蛇床子), CORYDALIS TUBER(玄胡索), CINIAMOMI CORTEX(肉桂), CARYOPHYLLI FLOS(丁香), ALUMEN(枯白礬), AQUILARIAE LIGNUM (沈香). 4. The efficacy of medicines to use external medical treatment is as follow to help circulation of blood, to warm spleen and stomach, to warm blood, to warm uterus and remove cold, to remove heat and dry moisture, to down heat-product, to contract bloodvessel, to counteract poison and destory virus, to make energy and blood. 5. KUMBONGHYUNGJU, made same size as cherry and shape vagina medicine, use for Menorrhalgia, menstural irregularity, Leucorrhea, it has the efficacy as follow to remove cold and dry moisture, to warm uterus, to help circulation and romove pain, to down moisture-heat.

  • External pathogens such as wind, cold can easily invade the external parts of the body when host's external defense ability is not secure. Herein, we consider the underlying mechanisms against the external contraction at the body surface. During the early period after primary invasion, external defense mechanisms are gradually activated. The classic clinical manifestations are aversion to cold, fever, headache, generalized pain, and nasal congestion. This condition is called by invasion of external pathogen into the body surface. As the disease progress, lung qi is stagnated and thereby up-outward and downward movement action of lung become disturbed. Therefore, when doctor administrate formula to treat the exterior syndrome, doctor must keep in mind not only materia medica, but also underlying mechanisms through which many clinical symptoms appear.

  • Objectives The purpose of this case study is to report the effect of concurrent administration of Danguieumja-gagambang and external treatments on childhood psoriasis. Methods The subject is a child with psoriasis. This patient was treated with oriental herbal medicine (Danguieumjagagambang) and external treatments. The improvement of the skin condition is observed by Psoriasis Area and Severity Index (PASI) score. Results After the treatment, the symptoms of psoriasis were relieved. PASI score of this child went down from 4.7 to 0. Conclusions This study showed that concurrent administration of Danguieumja-gagambang and external treatments can be an effective choice for psoriasis.

  • Tracing the study of the burst test of steam generator tube, few studies have been reported to effect of external pressure acting on secondary-side in service condition. In this study the burst tests of Inconel 690TT were conducted in order to evaluate burst strength characteristics under the effect of external pressure. We obtained the result that the burst strength of Inconel 690TT increased when external pressure increased while both total circumferential elongation and uniform burst elongation were not affected. Also, according to the increased of external pressure, the size of the burst opening became smaller and the tear was getting severe.

  • Temperature distriburion in a hollow chlinder has been analyzed mathematically. Unsteady condition considered assumed a constant heat flux input from the inside. The results are compared with experimental results of surface temperature rise of a gun barrel during continuous firing. Their agreements are acceptable. Effects of various dimensionless parameters on the surface temperature rise are discussed. For small Biot numbers, the external survface temperature approaches more rapidly to the steady temperature. Temperature difference between internal and external surfaces becomes greater for small Biot number. Steady solution assumed that the gas temperature inside the cylinder varies periodically. Relative amplitude and phase angles between the gas temperature and the internal or external surface temperature are obtained. Phase angles become smaller for large radiancy of gas temperature variation, small external Biot number, or large internal biot number. Relative amplitudes become samller as radiancy of gas temperature variation and internal Biot number become smaller. or external Biot number becomes larger. The solution obtained in this paper can be applied to gun barrels, heat pipes used in heat excangers, and reciprocation engines.

  • This study is on the external environment of University library organization, to establish the theoretical background of scientific organization. The library is heavily influenced by its environment and much of the library manager's time is spent trying to reduce these envitronmental influences. The library, basic facility of the university has two environments: external and internal. The external environment is consist of educational, political, economical, cultural, technological and physical environment in society, Internal environment is consist of the university and the library condition. Several subjects of external environment which effect the construction of library organization are selected the elements of this study.
