The number of the enterprises which utilize network technology has been increasing for solving problems such as productivity improvement, market trend analysis, and material collection for making decision. Especially, the management of equipment and the recovery time reduction when machines break down are very important factors in productivity improvement of the enterprise. Currently, most of the remote trouble diagnosis of equipment using the internet have just one function of transmitting the trouble information to the user. Therefore it does not directly reflect the user's recovery experience or the developer's new recovery methods. If the user's experienced recovery methods or the developer's recovery methods as well as the basic recovery methods are reflected online or on the internet, it makes it possible to recover faster than before. In this paper, we develop a Remote Monitoring Server (RMS) for chip mounters, and make it possible to reduce the recovery time by reflecting the user's experience and developer's new methods in addition to presenting the basic recovery methods. For this, trouble recovery concept will be defined. Based on this, many functions(trouble diagnosis, the presentation of the basic recovery methods, user's and developer's recovery method, counting function of the trouble number of each code, and presentation of usage number of each recovery methods) were developed. By utilizing the reports of the actual results of chip mounter and the notice function of the parts change time, the rate of operation of the chip mounter can be improved.

The purpose of this study was to identify emotional responses, of stroke patients using Q analysis. From the data analysis, five types of emotional responses in stroke patients were classified as follows. 1. Acceptance and Overcoming : They attached to life strongly and had self-confidence of recovery. They were striving against their situation through using anything else good for their recovery. 2. Anger Type : They recognized a labile feeling and were angered easily. They had a self-confident and self-esteemed personality before they had a stroke. 3. Conflict Type : They wanted interaction with others. This individual recognized that no one knows their agonies. They were thankful to god or their family, while they could not control their minds. Their family supports were low. 4. Deficiency of self-esteem Type : They had a self-confidence of recovery, but they were in fear of interaction with others. Especially, they were ashamed of themselves. They have a high sense of responsibility and nigh self-esteem for themselves before they had a stroke. 5. Despair Type. : They were sorry to trouble their family. They felt depression, anxiety, darkness, uselessness of themselves, and they wanted to die. They recognized financial burden. for their family. The characteristics of the five types of stroke patient identified in this study will be used to assess emotional nursing needs for stroke patients. The findings of this study will provide practical guidelines for developing nursing interventions for stroke patients based on the characteristics of subjectivity types.

The purpose of this study by examine the effect of visual neglect on hemiplegia motor recovery are showing trouble which can be raised by visual neglect and helping the patient's ADL and functional recovering. Among the patients who are being taken physical therapy in many other hospitals in Busan From February 1st 2002 to august 31st, we chose 20 patients as control group who did not have symptoms of visual neglect and 20 other patients who did have as case group. We used Albert's test and line bisection as visual neglect test, and MAS as motor recovery. The average age of the patient group is 51.55 and that of control is 44.9. The men's rate is higher than women' s in both groups. Although the rate of left hemiplegia is higher than right hemiplegia in case group, that of right hemiplegia is higher than left hemiplegia in control group. There is much lesion site of basal ganglia in case group. There is the most amount of transformation of MAS when visual neglect is shorter than 1.5centimeter. Each change of MAS point before and after therapy in case group and control group is revealed $6.5{\pm}4.37$ and $12.5{\pm}5.95$.

본 연구의 목적은 여성독거노인이 자살위기에서 벗어난 경험과 회복과정을 연구하여 참여자들이 회복으로서의 인생의 본질적 의미와 구성요소가 무엇인지, 또한 변화된 생각과 인생에 대한 현상은 무엇인지를 알아보았다. 본 연구의 결과는 자료분석을 통해 4개의 구성요소와 8개의 하위구성요소, 16개의 의미단위 축약이 도출되었다. 여성독거노인의 자살시도와 회복 경험의 구성요소는 4개로 단절과 불통, 거듭되는 시련, 곤경 속의 형통의 길, 너그러운 포용으로 나타났다. 구성요소의 본질적인 주제는 참여자들의 삶에서 개별적인 것이 아니라 각각의 주제가 전체적 맥락적으로 연결되어 있었다. 결과를 정리해보면 여성독거노인의 자살시도와 회복 경험의 본질적 의미는 역기능적인 사회구조와 환경의 결과물로 인하여 연구 참여자들의 삶을 괴롭게 하였다. 이를 극복하기 위한 방법적 대안으로 자살이라는 극단적 실행으로 문제를 해결하려고 했으나, 자살실패를 하게 되고, 이 과정에서 인지된 내면의 회복요인들이 다시 살아갈 수 있는 긍정적 에너지가 되었다. 이러한 전환된 시각이 힘든 현실에 맞설 수 있는 것으로 나타났다.

It is well known that discard of seminal plasma from the semen and separation of motile sperm should be preceded before insemination for IUI or IVF. Till now, more than ten kinds of semen treatment methods have been developed. Of those, swim-up and Percoll methods have been used widely in ART laboratories as a routine semen treatment methods because of its advantages. However, there are reports that Percoll can make a genetic trouble because of its chemical structure and therefore the necessity has been arisen to substitute Percoll for other equivalent materials. This study was performed to evaluate the effects of three different sperm preparation methods (swim-up, Percoll and Sil-Select) on sperm motility, sperm recovery rate and fertilization rate. Also, the feasibility of using Sil-Select instead of Percoll in ART was evaluated. Each semen samples were divided into three fractions and motile sperm were recovered by swim-up, Percoll and Sil-Select gradient centrifugation methods. Normal and sub-normal criteria of fifteen semen samples and seventeen IVF cycles were included in these study. As results, no significant difference was found in sperm recovery rate in normal semen treated by a Swim-up, Percoll and Sil-Select method ($13.2{\times}10^6,\;17.5{\times}10^6\;and\;17.7{\times}10^6$ respectively). The initial sperm motility was 61.9% and this increased to 87.1%, 92.6% and 89.5% through Swim-up, Percoll and Sil-Select treatment, respectively. Higher motility was observed in Percoll and Sil-Select treated groups (81.5%, 79.2%, respectively) than swim-up group (66.8%) after incubation for 24hrs. In sub-normal group, sperm recovery rates were higher in Sil-Select group $(2.9{\times}10^6)$ than Percoll gradients group $(1.8{\times}10^6)$. In IVF cycles, the outcomes of fertilization using sperm treated by swim-up and Sil-Select group were similar (82.2%, 79.7% respectively). In conclusion, our results indicate that Sil-Select can be used as a substitute material for sperm preparation instead of Percoll.

최근에 태양광 발전 시설이 급격히 증가됨에 따라 사용 후 태양광 모듈의 발생량이 급증할 것으로 예상된다. 태양광 폐 모듈의 리싸이클링은 일부 국가에서 시도하고 있지만, 경제성이 확보된 실용화 기술의 부재로 폐 모듈이 방치 및 폐기되어, 환경오염은 물론 유가자원 회수 측면에서도 많은 문제를 야기시키고 있으므로 대책 마련이 시급하다. 이와 같은 현실에 비추어 본 기술개발에서는 폐 모듈의 성능검사, 알루미늄 프레임 해체, 강화유리의 파분쇄 및 박리, back sheet 및 EVA의 분리 제거, 유가금속의 침출과 침전 회수 및 폐액 처리의 기반 기술을 확립한 다음, 이를 기초로 대단위 처리 시설을 설계 제작 및 운전함으로써 실용화기술을 확립하였다. 본 연구에서는 대단위 시험을 통하여 1 ton/day 규모의 폐 모듈 처리의 최적 조건을 확립한 다음, 얻어진 자료를 근거로 경제성 검토를 실시하였다. 프레임 해체 및 강화유리 박리 공정까지는 경제성이 있었으나, 유가금속 회수를 포함한 전체 공정을 포함하면 생산자 책임(EPR) 제도의 시행에 따른 재활용 분담금의 지원이 이루어지지 않는 한 경제성이 박약하였다. 향후 태양광 폐 모듈의 수거, 재사용 인증기준, 철거비 부담, 효율적인 처리 기술 확보, 관련 법규제정 및 EPR 제도 등의 문제가 해결된다면, 경제성 확보가 용이하여 상용화가 가능할 것이다.

Objective : Doctors who treat women in childbed have to pay attention to postpartum blues and depression which women in childbed can suffer from, as well as recovery of physical function. Methods : Subjects were 107 females who admitted in Woosuk Hospital of Oriental Medicine from September, 2000 to October, 2001 and made out the question paper within 10 days after delivery. The paper included EPDS(Edinburgh Postnatal Depression Scale) and many items known to be the factors related to postpartum blues and depression. Results : The rate of postpartum depression assessed by EPDS was 16.8%. As the result of analysis, there were significant statistic corelations between each group assessed by EPDS and age parity relation with husband yes or no living with parents-in-law. But there were no significant corelations between each group assessed by EPDS and education religion yes or no occupation delivery method sex of infant marriage type yes or no rearing the infant. Conclusions : We recognized that insufficiency- of delivery experience and stress due to bad adaptation after delivery are possible to be risk factors of postpartum blues and depression. More research should be taken on the corelation between postpartum depression and yes or no living with parents-in-law, because this result is opposite to the trouble between mother-in-law and daughter-in-law. In addition, more research is needed on corelation between physical condition, oriental-diagnosis of women in childbed and postpartum depression.
