The purpose of this study is, by using Q-methodology, to classify the type of attitude for the general public about the death and to understand the specific characters of each type. Q-population was investigated by referring to relevant records and interviewing with the general public and the experts. The final 40 of Q-sample was selected and the data was collected through P-sample, randomly chosen 32 people around Seoul and Kyung-gi area. After analyzing, 4 types were found. Type 1 is aiming for the future life. They believe firmly the future life. They feel certain that eh death means starting for eternal life rather than being afraid of the death or having a despair. Type 2 is valuing reality. They do their best for the reality of life. They take up a positive attitude toward completing their life with responsibilities even at the situation of confronting death have a right to know when they will be dead. They should have enough time to prepare for death. Type 4 is devoting for society. Even though there is only one life, people think that devoting their life for justice is very important. Through the result of this study, people's agreement for nobility and importance of life were found same. It is reconfirmed that instead of being dead suddenly, if it's possible, they want to know the fact of dying to have time to prepare for their death. Also, the fact that everyone has the fear of death is confirmed.

Pseudomonas putida SM25로부터 protocatechuate 3,4-dioxygenase 를 암호하는 pcaHG 유전자를 클로닝하기 위하여 이미 알려져 있는 primer를 제작한 후 P. putida SM25의 염색체 DNA를 주형으로 하여 PCR product인 약 1.6 kb DNA 절편을 얻었다. 이 DNA 절편을 SalI과 EcoRV로 절단한 약 1 kb DNA 절편만을 probe로 사용하여, PstI으로 절단한 염색체 DNA 전편과 Southern blot을 실시한 결과, 4.4 kb의 PstⅠ DNA 절편을 얻었다. 이 절편을 pUC19 vector에 삽입하여. 재조합 플라스미드 pYJ27을 얻었으며, 이 재조합 플라스미드의 SphI, EcoRV, Pstl,SalI, Aval 등을 사용하여 제한효소 지도를 작성하였다. Insert DNA를 서브 클로닝 하여 pcaHG 유전자를 포함하는 DNA 절편의 염기서열을 결정한 결과, pYJ27에는 1336bp 크기인 두개의 open reading frames(ORFs)가 존재하였으며 protocatechuate 3,4-dioxygenase에 해당되는 437개의 아미노산을 암호하였다. 이미 보고된 protocatechuate 3,4-dioxygenases의 DNA 염기서열을 비교한 결과, Pseudomonas putida ATCC 23975와는 94% 정도의 비교적 높은 homology를 보였다. 또한 Rhodococcus나 Acinetobacter에서는 각각 63%, 55%의 homology를 보여 주었다. Protocatechuate 3,4-dioxygenase catalyzes the conversion of protocatechuate to β-carboxymuconate through the cleavage of the aromatic ring. The genes encoding subunits of the protocatechuate 3,4-dioxygenase were designated pcaH and pcaG, respectively. The locations of the genes for the α and β subunits of protocatechuate 3,4-dioxygenase on a 4.4 kb PstI fragment cloned from the Pseudomonas putida SM25 chromosome were determined. A 1.6-kb DNA fragment from a 4.4kb recombinant DNA was cloned into pUC19 vector, pYJ27. Recombinant plasmid pYJ27 was mapped with various restriction enzymes, SalI, EcoRV, PstI, SphI, and AvaI. According to bidirectional subcloning and method of dideoxynucleotide chain termination, we determined the nucleotide sequences of the recombinant DNA fragment pYJ27 containing pcaHG gene. The deduced amino acid sequences of pcaG and pcaH were consisted 200 and 237 amino acid, respectively. The pcaG and pcaH showed about 94% homology to that of P. putida ATCC 23975 in the nucleotide sequences.

This study attempts to identify the self-image of eyeglass wearers with Q-methodology. Preliminary Q-statements were collected through personal and telephone interviews and based in consultation with reference books, eyeglass wearers, an optician and an oculist. Finally,34 Q-samples were seleted. The results were analyzed by a Q-factor with a PC QUANL Program. The sell-image of eyeglass wearers were found to revolve around three types: Type 1. They feel that eyeglasses have a negative inf1uence on image and that they uncomfortable. In addition, other people have a negative bias toward people who wear eyeglasses. As a result of these negative prejudices and inconveniences, there is a tendency to wear contact lens or have laser operations. Type 2. They feel less uncomfortable comparatively', when explained that classes can help improve their image. When explained as a fashion accessory, negative prejudices almost disappeared. Type 3. They show a positive reaction when explained that spectacles are also rosed for sight protection. However, they are sensitive to changes in their complexion as a result of eyeglass wear and place much importance in the design of glass frames. The significance of this study is to suggest basic data for a mediation device that improve the image of eyeglass wearers discovery and analysis of these three types.

The objective of this study is to find the most effective educational method on Sex and AIDS/HIV among young people in Korea. The number of people with HIV amounts to 1,224 as of Sep. 2000, and is increasing continuously, especially among young people(National Institute of Health, 2000). In setting up the policy of health education on Sex and AIDS, the criteria should be the effectiveness. By two-stage cluster sampling, 4,713 students were selected from among the 19,093 students from 44 middle and high schools and divided into three groups and taken the education with three different methods(〈lecture with slides show〉, 〈lecture without any material〉 and 〈lecture through broadcasting system〉) by the same lecturer with the same contents for about 50 minutes. To compare the effects of education by methods, the tests on the AIDS knowledge, AIDS attitude on AIDS and Sexuality attitudes with self-administered questionnaire were implemented three times, that is, 'before', 'right after' and '2 weeks later' of the education. As to the decrees of change of AIDS knowledge, AIDS attitudes, Sexuality attitudes and subjective evaluation of the education, 〈lecture with slides show〉 was the most effective, 〈lecture without any material〉 was the second and 〈lecture through broadcasting system〉 was the least effective, respectively. In the cost-effectiveness analysis using the results of this study, 〈lecture with slides show〉 turned out to be the most effective, and 〈lecture through broadcasting system〉 was the second and 〈lecture without any material〉 was least effective. From these results, it is suggested that 〈lecture with slides show〉 is more effective health educational methods on Sex and AIDS than 〈lecture without any material〉 or 〈lecture through broadcasting system〉.

This studies designed to work out a theoretical framework on the experience of sexual abuse from the perspective of grounded theory in an effort to provide more practical and efficient nursing intervention for female victims. The subcategories identified were "sexual abuse", "threatening", "absent mindness", "embarrassment", "horripilation", "dizziness", "wondrousness", "filthiness", "sexual curiousity", "violence level", "victim's age", "neighbors response", "victims personality", "common experience", "sexual abuse information", "family relations", "level of familiarity", "hiding", "suppression", "self-torture", "self-protection", 'avoidance", "asking aid", "withdrawal", "hatred", "confusion", "dodging", "remmant", and "pursuing". The 29 subcategories given above were further integrated into 16 categories such as "victimizedness", "being astounded", "filthiness", "degree", "developmental stage", "response pattern", "personality", "rarity", "infromation availability", "family support", "cover-up", "escaping", "informing", "negative internalization", and "positive pursuit of change". The core categories linked to all the other categories turned out to be "being taken aback" and "filthiness" incorporation the relevant subcategories. A total of 23 theoretical hypothesis emerged in the process of analyzing data. 1. the grater sexual curiosity, the weaker the senses of being taken aback and filthiness. 2. The weaker sexual curiosity, the stronger the senses of being taken aback and filthness. 3. The stronger the level of violence, The more violent the senses of being taken aback and filthiness. 4. The lower the level of violence, the weaker the senses of being taken aback and filthiness. 5. The younger the victims, the stronger the senses of being taken aback and filthness. 6. The older the victims, The weaker the senses of being taken aback and filthness. 7. 'Escaping' will transpire regardless of the given circumstances. 8. The weaker the senses of being taken aback and filthness, the more probable 'informing' and 'escaping' transpire. 9. The stronger the senses of being taken aback and filthness, the more probable 'informing' and 'escaping' transpire. 10. The more protective the response from 'informing' and 'escaping' transpire around, the more likely the response to 'being taken aback' and 'filthiness' will be 'informing' and 'escaping'. 11. The more repelling the response from around, the more likely the response to 'being taken aback' and 'filthiness' will be 'covering-up' and 'escaping'. 12. The more open minded the personality of subject, the more likely the response to 'being taken aback' and 'filthiness' will be 'covering-up' and 'escaping'. 13. The more closed the personality of subject, the more likely the response to 'being taken aback' and 'filthiness' will be 'covering-up' and 'escaping'. 14. The more frequent the experience of sexual abuse, the more likely the response to 'being taken aback' and 'filthiness' will be 'covering-up' and 'escaping'. 15. The less frequent the experience of sexual abuse, the more likely the response to 'being taken aback' and 'filthiness' will be 'covering-up' and 'escaping'. 16. The more available information concerning sexual abuse, the more likely the response to 'being taken aback' and 'filthiness' will be 'covering-up' and 'escaping'. 17. The less available information concerning sexual abuse, the more likely the response to 'being taken aback' and 'filthiness' will be 'covering-up' and 'escaping'. 18. The more cohesive the family of the subject, the more likely the response to 'being taken aback' and 'filthiness' will be 'covering-up' and 'escaping'. 19. The less cohesive the family of the subject, the more likely the response to 'being taken aback' and 'filthiness' will be 'covering-up' and 'escaping'. 20. The more familiar the subject is with the abuser, the more likely the response to 'being taken aback' and 'filthiness' will be 'covering-up' and 'escaping'. 21.The less familiar the subjec is with the abuser, the more likely the response to 'being taken aback' and 'filthiness' will be 'covering-up' and 'escaping'. 22. The more likely the response to 'being taken aback' and 'filthines' is 'informing' and 'escaping', the more positive changes the subject will pursue. 23. The more likely the response to 'being taken aback' and 'filthiness' is 'covering-up' and 'escaping', the more negative changes the subject will pursue. The following four hypothneses were conformed in the process of data analysis. 1) In case the level of violence is strong but 'being taken aback' and 'filthiness' in weak because of strong sexual curiosity and also if information concerning sexual abuse is not readily available and the frequency is low, negative internationalization marked by 'covering-up' and 'escaping' will take place despite the fact the subject is open-minded, the family is cohesive and the abuser is unfamiliar. 2) In case the level of violence is weak but 'being taken aback' and 'filthiness' is weak combined wit weak sexual curiosty and also if information concerning sexual abuse is readily available and the response from around is protective and the frequency is high, the subject will pursue positive changes to 'being taken aback' and 'filthiness' , further aided by the fact that the subject is open-minded, the family is cohesive and the abuser is unfamilar. 3) In case the level of violence is strong but 'being taken aback' and 'filthiness' is strong because of weak sexual curiosity and also if information concerning sexual abuse is reading available and the response from around is readily available and the response from around is protecvice and the frequency is low, the subject will persue positive changes marked by 'informing' and 'escaping' despit the fact that the family cohesion is weak and the abuser is familiar. 4) In case the level of violence is strong but 'being taken aback' and 'filthiness' is strong because of weak sexual curiosity and also if information concerning sexual abuse is not readily available and the response from around is respelling and the frequnecy is low negative internalization like 'covering-up' and 'escaping' will take place, further aggravated by the fact that the subject's personality is closed, family cohension is weak, and subject is familiar. On the basis of the above finding, it is recommended that nursing intervention should focus on promoting the milieu conductive to the victims pursuing positive changes along with the adequate aids from protection facilities as well as from the people around them.

The purpose of this study was to investigate for filtration efficiency of several dust masks, comparing with filtration efficiency certified by KOSHA(Korea Occupational Safety & Health Agency), and to require of the right use of protective respirator. Using a welding fume generator and chamber, several dust masks, which were widely used in the workplaces in korea, were tested for their filtering efficiency for stainless steel are welding fume. The filtration efficiency testing system consisted of a welding fume generator, a chamber and a filtration unit. The filtration unit was made of a mask which was inserted into the sampling cassette and another sampling cassette, which contained mixed cellulose ester filter paper. These two cassettes were connected with tubing. Stainless steel arc welding fume generator was delivered into an chamber. The welding fume in the chamber was passed into the filtration unit with flow rate of 30 liter/min. The welding fume filtration efficiency was evaluated by gravimetric measurement. Metal concentrations in the welding fume before and after filtration were measured with inductive coupling plasma analyzer. Following results were obtained: Filtration efficiency of welding fume for comm hygienic mas was 63.82% and the average efficiencies for A, B, C, D, E, F and G masks were 94.62% 96.58%, 83.20%, 82.76%, 77.25%, 86.55% and 93.22%, respectively. Our results indicate that dust masks used widely in the welding workplaces in korea are not proper for protecting worker's health and then the use of fume mask should be required.

The purpose of this study was to compare visual analogue scale (VAS), pain threshold (PT), %RMSRVC, and EMG gaps before and after applying transcutaneous electrical nerve stimulation (TENS) on the upper trapezius muscle at the patients with myofascial pain syndrome (MPS). The subjects were 4 men and 10 women composed of both the inpatients and outpatients who were diagnosed as MPS at Wonju Medical Center. VAS and PT measurements were performed to assess the subjective pain level. The reference voluntary contraction (RVC) test was performed for 15 seconds for normalization on the bilateral trapezius muscle using surface electromyography (sEMG). After 3-minute resting time, the EMG signal was recorded while performing a typing activity for 2 minutes and then TENS was applicated with a comfortable intensity for 10 minutes. The EMG activity of the upper trapezius muscle was recorded during typing for 2 minutes. The results of study were as follows: 1) VAS score was significantly decreased on the more painful side after treatment, however, it was not significantly different on the less painful side. 2) PT was increased after treatment on both sides, however, it was not significantly different between before and after the TENS application. 3) The EMG activity during typing was significantly decreased after treatment, and 4) The EMG gaps were significantly increased after TENS treatment compared to before it. Consequently, the study showed that TENS was effective in decreasing VAS, %RMSRVC, and in increasing EMG gaps. The EMG gap analysis could be a useful method to measure pain in patients with MPS in the upper trapezius.

In this paper, we propose a nonlinear system identification method using genetic algorithm. We represent the nonlinear system as a parameter vector and a measurement vector. In order to identify the nonlinear system, we find the parameter vector using genetic algorithm. The parameter vector is regarded as a chromosome of gene. The error between the desired output and estimated output every sampling period is used to calculate the fitness of one gene. The simulation results showed the effectiveness of using the genetic algorithm in the nonlinear system identification.
