Objectives: Cocaine has been well known as a representative drug of abuse for its strong reinforcing effect linked to the mesolimbic reward system including dopamine, and such reinforcement leads to the addiction. Acupuncture has been used widely in eastern Asia for the treatment of various diseases including mental disorders and psychiatric problems, and is gathering more interest as one of the complementary and alternative medicines in western countries. In a previous study, we demonstrated that acupuncture at HT7 could affect dopamine release in the mesolimbic system of rats sensitized to alcohol and morphine. This study was designed to investigate whether acupuncture at HT7 could attenuate cocaine intake or not. Material & Methods: Male Sprague-Dawley rats weighing 270-300 g at the start of experiment were trained to self-administer food pellets under a fixed ratio 1 schedule. After the success of acquisition of 100 pellets within 3 h for 3 consecutive days, animals were subjected to surgery whereby Silastic tubing was implanted into right jugular vein and secured with mesh under the anesthetization using pentobarbital injection (50 mg/kg, i.p.). Following recovery, rats were trained to self-administer cocaine (0.25 mg/kg) in daily 2 h sessions under fixed ratio 1 schedule over 10 days. Each treatment was performed on the next day of each establishment of baseline. Results: Results show that acupuncture at HT7, but not at control points, reduced cocaine intake significantly. Acupuncture at HT7 decreased selectively active lever response from $63.15{\pm}3.35$ to $51.46{\pm}3.99$ corresponding $82.12{\pm}5.31%$ compared to basal level. Also, it was demonstrated that the effect of acupuncture was mainly occurred at the half period. Nevertheless, acupuncture at HT7 did not influence the food taking behavior. Conclusions: From the results of this study, it may be suggested that acupuncture at HT7, at least in part, could contribute to the treatment of cocaine abuse.

Technical change and technological innovation have become major drivers of economic progress in the knowledge oriented economies where growth, productivity, and competitiveness are increasingly based on improved technologies, novel products, upgraded processes or customized services. The creation of new knowledge, modifying or improving existent knowledge, or imitation of others, has become central to economic development. New discoveries, state-of-the-art information gathering procedures, or successful problem solving routines are often at he core of these innovations. Despite the generally acknowledged importance of science in many high-tech areas of major economic relevance, there is few science-related statistics to be found in high-profile international benchmarking reports. This paper aims to provide an answer by advancing our understanding of the possibilities of indicators quantifying linkages between science and technology. Central are the concepts of innovation capability and science/technology interface, which are used to assemble a wide range of empirical studies and quantitative indicators to summarize their possibilities and limitations for producing comparative statistics. For the purpose of the study, we extracted the US patents by Korean assignees or inventors, scientific papers cited in the patents in order to analyze the characteristics of linkage of scientific knowledge flows. The review focuses on indicators dealing with flows of written or codified information, and indicators of inventiveness that capture the non-codifiable tacit knowledge dimension. General conclusions will be drawn with a view towards further developments in the foreseeable future, suggesting new avenues for the design and implementation of patent-based and inventor-based relationships between scientific research and technical development within the context of regional or national systems of innovation.

Purpose - Lettuce (Lactuca sativ L.) is one of the economically important vegetable crops, which worldwide market value is over 100 billion U.S. dollar. In Korea, about 89.7 kilo ton of lettuce was produced in 3400ha in 2016, recoded as No. 1 vegetable crop in domestic green house production. However, recently, domestic lettuce production and cultivation areas are all getting decreased. Thus, novel approaches are needed to be implemented to revive the production. Research design, data and methodology - In this review paper, we first prioritized the end-user traits which are imperative to positively stimulate the domestic lettuce market and discussed relevant genomics strategies. Especially, we assessed a possibility whether school meal program would be a potential niche market. Results - The genomics technologies, which become widely applied in the crop biotechnology since 2008 when next generation sequencing method was developed, may be a good solution in the crop improvement, efficiently gathering valuable information of agriculturally useful traits. Significantly, in lettuce, the high quality whole genome sequence, based on Lactuca sativa cv. Salinas, is publically available and this genomics platform, thus, would be implemented in lettuce breeding program to innovate relevant end-user traits both for the farmers and customers, including the disease resistance to the Fusarium wilt, productivity under hot weather conditions, various nutritional qualities and so forth. These improvements will boost domestic lettuce industries in the near future. Conclusions - Due to the nutritional distinctions comparing to the western style lettuces, domestic leaf lettuces could be one of the important vegetables in the school meal programs. To make it happen, we would better devise diverse recipes to make a salad with it, instead of only using as a wrap vegetable. Meanwhile, novel lettuce varieties need to be developed, which are favorable to the students and also easy to be handled with while processing. Overall, to achieve international competence in the lettuce industries, we need to create elite lettuce varieties that satisfies domestic farmers as well as customers, suitable to various niche markets, such as school meal program. Thus, efficient breeding programs using genomics approaches should be established in advance and careful monitoring on the preference of the related customers for a niche market be continued persistently.

This study has verified Family Functioning, Communication and Spiritual Wellbeing, to increase the family functioning in Adult Women. 236 adult women were chosen as the samples for the study, they are now currently registered in the church adult women in Seoul. The instruments used for this study were the Family functioning scale by Olson, the communication scale by David H. Olson and Howard L. Barnes and spiritual wellbing Scale by Palautzian and Ellison Folkman. Data collection were form March to April, 2003. To get the descriptive statistics, SPSS Program, Pearson Correlation Coefficients and stepwise multiple regression were used for analyzing data. The results were as following: 1. Represents the degree of family functioning, communication and spiritual wellbeing, on subjects. Means scores of this study are following: spiritual wellbeing 67.92, lower level of cohesive(5.19) and adaptive(3.93), communication 58.14, lower level of open(5.15) and closed(4.71) and family functioning 95.58, lower level of religious(7.70) and existential(7.63). All each lower level of family functioning, communication and spiritual wellbeing, on subjects were derived significantly different(p.05). There were significant correlation among the variables of subjects. The cohesive family functioning score was significant related to the adapted(r=.588). Especially, the closed communication score showed inverse correlations open family functioning(r=-.424) and open communication score(r=-.680). The existential spiritual wellbeing score also was significant related to the cohesive(p<.001) and adaptive(p<.05) family functioning, open communication(p<.05). Especially, the closed communication score showed inverse correlations existential spiritual wellbeing (r=-.202). The existential spiritual wellbeing score also was significant related to the religious(r=.815, p<.001). These results will not only emphasis the need of family functioning to elevate and decrease the Closed family communication but suggest the important points of gathering various data and analysis about economic, education and marital status. Finally, related to mental health nursing, a community can get the utmost out of these results to keep offering education and practice of family mental health for adult women.

Recently, with increase and development of the wireless access network area, u-GIS Service is supported in various fields. Especially, spatio-temporal data is used in the mobile environment for the u-GIS service. However, there is no standard for the spatio-temporal data used in different spaces, spatio-temporal data processing technology is necessary to makes interoperability among mobile u-GIS services. Furthermore, it is also necessary to develop the system of gathering, storing, and managing the spatio-temporal data in consideration of small capacity and low performance of mobile devices. Therefore, in this paper, we designed and implemented a spatio-temporal query processing system based on GML to manage spatio-temporal data efficiently in the mobile environment. The spatio-temporal query processing system based on GML can offer a structured storage method which maps a GML schema to a storage table and a binary XML storage method which uses the Fast Infoset technique, so as to support interoperability that is an important feature of GML and increase storage efficiency. we can also provide spatio-temporal operators for rapid query processing of spatio-temporal data of GML documents. In addition, we proved that this system can be utilized for the u-GIS service to implement a virtual scenario.

The purpose of this study is put on the evaluation of public support for media with the case of Special Act on Supporting Local Press whose main purpose can be said to help local press in crisis intending the improvement of news quality. However, it was controversial whether public support on specific media under the governmental leadership, which is related to the disputes on its abrogation with the change of the regime. Therefore, this study tries to evaluate its achievement focused on its effect on the diversity of public opinion especially with the eyes of audience. In-depth interviews were executed to find out whether it had helped local press to improve public interest for the last three years of public support. The interviewees, the readers as well as monitors of local press, answered that there had been some improvement in news quality and diversity of local press in general. However, they thought that fund support for news gathering cost was problematic and would be negative in the long-term perspective. In conclusion, the interviewees regarded Special Act on Supporting Local Press as necessary one to help local press in crisis but pointed out also that the act might not enough to change local press because the situation they were facing is so complex. Hence, this study argues that the evaluation of Special Act on supporting Local Press should be approached Abstracts 683 not on the basis of political logics but of the public interest and democracy.

Purpose: The purpose of this study is to survey health requirements of middle-aged women and their families and to provide guidelines for developing nursing interventions by describing the process of family health maintenance experienced by middle-aged women and its conceptual system. Methods: To get saturated data, each of four researchers conducted two or three times of in-depth interview with eight middle-aged women aged between 40-64 years old and living in Seoul and Chuncheon from the 10th to the 30th of October 2004 and each interview was continued one or two hours. The Grounded theory adopted by Strauss & Corbin (1998) is a substantive theory that can explain the experiencing process of middle-aged women. Results: We found that the casual condition of family health maintaining by middle-aged women was 'confidence of health belief', and 'pouring by body moving' was found to be its phenomenon. A textual condition that might respond to the phenomenon was 'fatal roles acceptance', and intervening conditions that promote their family health were 'retracing' and 'gathering health information'. These intervening conditions impacted middle-aged women's confidence in family health and led them to take actions/interactions such as 'being a model of health', 'adapting to circumstances', 'do-it-myself', 'taking-care' 'harmonious mind' and 'the pursuit of cleanness'. These actions/interactions produced results such as 'being stronger', 'being unmanageable' and 'being fruitful'. Conclusions: Health confidence and practical health behaviors were observed in the process that the middle-aged female participants experienced unmanageable circumstances but they accepted their roles and responsibilities and recognized that they must be get stronger. The behaviors of health-together-with were divided into enthusiastic type, adaptation type and self-sacrificing type. Therefore middle-aged woman with the understanding of family health maintaining process as well as the theoretical system and practical principals needs to implement the intervention in acceptable level of family health process of preventing psychological and physical problems.

Portland cement production is under critical review due to high amount of $CO_2$ gas released to the atmosphere. Attempts to increase the utilization of a by-products such as fly ash and ground granulated blast-furnace slag to partially replace the cement in concrete are gathering momentum. But most of by-products is currently dumped in landfills, thus creating a threat to the environment. Many researches on alkali-activated concrete that does not need the presence of cement as a binder have been carried out recently. In this study, we investigated the influence of alkali activator and superplasticizer on the flowability and compressive strength of the alkali-activated mortar in oder to develop cementless alkali-activated concrete using blast furnace slag. In view of the results, we found out that the type and mixture ratio of alkali activator, the type and adding order of superplasticizer results to be significant factors. When cementless alkali-activated mortar using blast furnace slag manufactured with 1:1 the mass ratio of 9M NaOH and sodium silicate, and added superplasticizer before alkali activator in the mixer, we can be secured workability with 180 mm of flow during 1 hours and compressive strength of about 50 MPa under $20^{\circ}C$ curing condition at age of 28days.

This study was performed to investigate the general tendency of lower back Pain on nurses: influence of nursing activities, working condition and the physical characteristics of nurses on the pain in order to provide data for prevention and treatment. 386 nurses working at 16 general hospitals throughout the country were sampled. Questionaries developed by the researcher was used for data gathering. Results are as follows : 1. Lower back pain was experienced by most(72.3%) of the nurses: the highest rate of -Pain experience was revealed to be the a9e group of 35-39 (80.8%) followed by 25-29 group (74.2%). 2. In almost all instances (91.4%), the first pain attack occurred before the age of 29, and in 73.1%. the attack occurred between the age of 15-24. 3. In 10.1%, the pain was almost persistent or occurred every other day frequency. In 9%, the pain was relieved by the administration of analgesics or "unable to move". 4. More than 6 days′sick leave due to the pain revealed to be in 2.2%. No significant difference was revealed between specialities of service. 5. Pain experience and the over or under weight revealed not to have significant relations. (X$^2$=0.55224, p〉0.7587) 6. The length of working hour of I. C. U. and O. R, revealed to be longer than that of nurses general ward, however. no significant difference on the rate of pain occurrence apparent. (X$^2$=0.4952, p〉0.8239) No significant difference on the rate of pain occurrence between nurses working over 46 hours/week and under 45 hours/week. (X$^2$=3.86241, p〉0.078318) 7. The most frequent Pain related movement revealed to be "lifting patient or heavy object" (24. 7%, N=68) followed by "the sameness of position, either standing or sitting"(16.8%) 8. Regular physical exercise revealed to have no significant influence on the rate of Pain occurrence. 9. Higher raft of pain experience was revealed in the group of nurses wearing eye glasses. Uncomfortable shoes revealed to have influenced the pain. 10. The most frequent pain relieving treatment revealed to be "rest" (54.2%, N= 151) followed by "analgesics" (12.6%, N=35) and "hot compress/fomentation"(10.5%, N=29). In 13.7% (N=38) no special care was given.
