Purpose: This paper proposes a performance evaluation method for state-of-the-art facility inspection/diagnostic equipment through a trend survey of equipment and standardization systems of US, Japan, and Korea. This paper also suggests the priority of developing a performance evaluation method through expert interviews and surveys. Method: In this study, report for the last 5 years of FMS, state-of-the-art equipment of facility maintenance companies/safety diagnosis specialist agencies and papers/research reports/patents of NTIS were analyzed to identify recent trends of facility inspection/diagnostic equipment usages. standardization system of US, Japan, and Korea were analyzed to figure out a suitable form of a performance evaluation method for the domestic situation. And expert interview and survey were conducted to identify the priority of developing a performance evaluation method. Result: The performance evaluation method must be developed by the shape that only evaluates performance, regardless of types of equipment, on inspection item level for creative technology development. The priority of developing the performance evaluation method was identified as crack detection of concrete for durability evaluation and displacement/deformation/fatigue detection of concrete and steel for stability evaluation. Conclusion: The performance evaluation method will be developed firstly for the crack detection of concrete for durability evaluation and displacement/deformation/fatigue detection of concrete/steel for stability evaluation. In order to promote creative technology development, the performance evaluation method should be developed in a form that provides standardized specimens or testbeds and can be applied regardless of types of technologies.

Reviewing the trend of land use in urban cultivated land, the large part of land has been changed into the high-profit cultivated land of green houses or the developing areas. So, its percent of cultivated land in land use comparing to the other types of cultivated land would get far higher. Therefore, this study aims to identify the characteristics of landscape ecological pattern in the cultivated land of green houses and to find its alternatives for management, which would be a basis of regional planning and management in terms of space and time. The cultivated land of green houses, whose its area reaches 19.3ha, in Seoul are mainly dispersed on the south eastern part of Seoul and its area is larger than the other types of cultivated lands. According to the result of shape index analysis, its perimeters were very simple. Also, Analyzing the first three major neighboring land use to the cultivated land of green houses, the most frequent biotope types of neighboring land use to the cultivated land of green houses were that transportation facility represented 60%, forest, 43%, the other types of cultivated land, 36%, and residential area, 33%. The cause why the percent of transportation facility was higher in the neigh-boring land use types was assumed for the production and distribution of crops. On the basis of the result of landscape ecological pattern analysis, the cultivated land would be managed and contributed to enhance biodiversity and urban environment preservation.

To analyze the current status of contact-lens in domestic, we analyzed the data of "The Spectacles-wearing Rate Analysis in 1999 (Korea Gallup Research)", "Industry current status(Korea Medical Instruments Industrial cooperative}", "Export & Import current status (Korea Customs Service)", and finally reached the following conclusions. 1. The number of contact-lens wearers in domestic could be assumed 2.13 millions. 2. The size of contact lens market in domestic(on year 2000 basis) was about 25.3 billion Korean wons(\) in total ; 10.8 billion Korean wons on the basis of production unit price (Domestic Gross Production Amount-Export Amount : used the subtraction in math), 14.5 billion Korean wons on Import unit price basis. 3. According to the year 2001 data, the import amount of contact lens is 1.7 times greater than export amount of that. 4. The contact lens export status in year 2001 was Japan, Singapore, Taiwan, U.S.A, China, Hong Kong, Malaysia, Thai, - in order. Especially, the contact lens export of China has increased gradually every year since 1998, the first export year of contact lens. 5. The import status of contact lens was U.S.A, Japan, England, Indonesia, Argentina, Taiwan, Hong Kong, - in order. In addition, the consumption trend of contact lens consumers in domestic reflects that famous foreign contact lens brands were much preferred than lower price contact lens imported from several developing countries.

In an effort to discover new technologies and to forecast social changes of technologies, a number of technology life-cycle models have been developed and employed. The hype cycle, a graphical tool developed by a consulting firm, Gartner, is one of the most widely used models for the purpose and it is recognised as a practical one. However, more research is needed on theoretical frames, relations and empirical practices of the model. In this study, hype cycle comparisons in Korean and global search websites were performed by means of web-search traffic which is proposed as an empirical measurement of public expectation, analysed in a specific product or country in previous researches. First, search traffic and market share for new cars were compared in Korea and the U.S. with a view to identifying differences between the hype cycles in the two countries about the same product. The results show the similarity between the two countries with the statistical significance. Next, comparative analysis between search traffic and supply rate for several products in Korea was conducted to check out their patterns. According to the analysis, all the products seem to be at the "Peak of inflated expectations" in the hype cycles and they are similar to one another in the hype cycle. This study is of significance in aspects of expanding the scope of hype cycle analysis with web-search traffic because it introduced domestic web-search traffic analysis from Naver to analyse consumers' expectations in Korea by comparison with that from Google in other countries. In addition, this research can help to explain social phenomina more persuasively with search traffic and to give scientific objectivity to the hype cycle model. Furthermore, it can contribute to developing strategies of companies, such as marketing strategy.

Being latecomers to the industrialization, Pacific rim countries except the U.S.A. are doing very little in developing the universal certification system. One should note that Asian Pacific region enjoys the highest economic growth rate, and there is a good possibility that it will be the center of economic activities of the world in the next century. It appears that ISO and CEN share similar specifications in numerous areas. ASNT is being changed to cope with the trend with the introduction of ACCP. Although we may have to adopt the new system someday, we should pay attention and make concerted effort to include our own practice in the global standards. We are the countries in the Far East Region with similar culture and tradition, which are quite different from those of western countries. We hope that Japan should play an important role in this matter, who has been chaired the ISO TC135 since 1993. In the beginning of this decade, there has been a trivial but troublesome matter that who is representing the NDT Society or member countries in Asia-Pacific Conference on NDT. The problem appears to be solved since the establishment of FENDT For the next decade, actually next centry, FENDT will have to accomplish another important role for countries in the Far East Region to form a strong coalition for its survival in the western dominant world. Immediate issue is to establish Far East Working Group for Harmonization and Mutual Recognition of Qualification and Certification of NDT Personnel. To realize this Japan must play a leading role with the cooperation of expanded FENDT member countries including China and Russia. As the continued prosperity expected in this region, FENDT should continue its role for the next centry. We, the FENDT countries, must move forward for internationalization(國際化). However' we must realize that it all start from SELF IDENTI-FICATION. We can identify ourselves by actively participating in FENDT. I would like remind you the concluding remark that I have made in the congratulatory speech at JSNDI 40th Anniversary Conference and FENDT'92. JSNDI is too precious to be Japan's sole possession Staling from the Far East, JSNDI shall become one of the loaders of the world. I sincerely hope that JSNDI take initiatives and leaderships in the future activities. of FENDT countries. I would like to close my talk with "We must hang together, or We shall be hang seperately."

Recently, the Japanese government revised the three guidelines of its security policy, the National Security Strategy(NSS), the National Defense Program Outline and Midterm Defense Buildup Plan, exceptionally at one time. This means Japan has been seeking the new strategy and strengthening military power considering changing regional security environment. Moreover, Japan revised the security laws for the right to collective self-defense, which authorized the use of force even when Japan is not under attack. Also, Japan renewed the Guidelines for Japan-U.S. Defense Cooperation in twenty years, and has expanded JSDF's scope of activity to a worldwide level. These changes imply Japan would constantly seek to build military forces focusing on naval forces. Because Japan's naval forces, the JMSDF is the means that allow Japan to use its force at anywhere overseas and expand its roles and missions in international society by the basis of the right to collective self-defense. This research will analyze Japan's new maritime strategy and trend of force development and eventually look for the implication on our maritime security These days, Japan has perceived Chinese rapid increase of naval power and pursuing of maritime hegemony as a grave threat. In response to this, Japan is designing new maritime strategy, which are "remote islands defense and recapture" and proactively develop a new type of naval forces to accomplish this new strategy. The Japan's "remote island defense and recapture strategy" is to harden its defensive posture in Nansei islands which correspond to China's 1st island chain for chinese A2/AD strategy and directly encounter with China and to protect its own dominium and maritime interest while supporting US national strategy in East Asia. Japan continues to build compact, multi-functional ship to accomplish "remote island defense and recapture strategy" and keep strengthening its maritime power projection capability to include build of new amphibious ship, and large, multi-functional ship which can provide effective C2. These changes imply that Japan is shifting its strategy from passive and defensive to proactive and aggressive way and continues to pursue naval buildup.The implication of Japan's new maritime strategy and naval buildup needs to be observed carefully and we need to keep developing naval power required to protect our maritime sovereignty and interest.

This study examined all the research published in Journal of Korean Academy of Nursing (JKAN) for last 30 years, from its beginning year to year 1999, based on an objective frame of evaluation. The purpose of this study is to reflect the trend of nursing research in Korea to date, and to provide an optimal direction for future research. The total number of 959 studies were analyzed with the following results. 1. Since 1990s, the number of non-degree based research has been larger than that of degree-based research compared to 1970s and 1980s. Both collaborative and funded research has been particularly increased in a gradual rate. 2. Research on nurses or nursing students has decreased while research on more diverse populations such as patients, patient families, or community-dwelling healthy clients has increased. 3. While essential nursing concepts such as human, nursing, and health have been consistently dealt as main research topics, research related to the concept of environ- ment has been insufficiently conducted. 4. It was remarkable that the quality of nursing research has been improved due to the acknowledgement of the importance of the empirical research method within the nursing community. 5. Qualitative research has appeared in the journal since the late 1990s, but it is still regarded to be in its novice stage. 6. Although the utilization of research findings for expanding the nursing body of knowledge has been wide in diverse specialties, most studies are limited to focus on concept development or evolution yet. also, in some of these research finding are utilization already considerably as to develop nursing interventions. Based on these findings, conclusions are extended to the following discussions: For the last 30 years, nursing research in Korea has shown an acute methodological development in both quantity and quality. However, there has been a lack of research on theory development although it is one of the ultimate goals in nursing. Further research should be empirical enough to be utilized in an actual nursing care context, and thus to be basis of developing culturally competent nursing theories in Korea.

An experiment was conducted to study the effect of different dietary protein levels on the performance, nutrient balances, blood biochemical parameters and thyroid hormones of crossbred calves. Thirty crossbred (Bos taurus${\times}$Bos indicus) calves aged 3-5 months were divided into 3 equal groups of 10 each and fed graded levels of crude protein, namely 100 (NP), 75 (LP) and 125 (HP) percent of the Kearl recommendations for 105 d. The calves had access to ad libitum oat hay as the basal roughage. A metabolism trial of 6 d duration was conducted at 90 d of the study. Blood collection and its analysis for various hematological and biochemical parameters as well as thyroid hormones was done both during the pre- and post-experimental periods. The fortnightly body weight changes and the net gain did not differ significantly due to dietary variation. The average daily gain was $367{\pm}21.6$, $347{\pm}22.9$ and $337{\pm}26.4g$ in calves fed NP, LP and HP diets, respectively. Averaged across the feeding trial, oat hay intake was higher (p<0.05) in NP animals than HP or LP fed groups. The dry matter (DM) intake showed no significant difference between the 3 groups but the DM digestibility was higher (p<0.05) in the HP fed animals. The digestibility of crude protein, organic matter, crude fiber and nitrogen-free extract was significantly higher (p<0.05) on HP diets compared to LP or NP diets. The calves on all 3 diets were in positive nitrogen (N) balance, however the N retention was higher (p<0.05) in HP than in LP fed calves. The intake and retention of calcium and phosphorus were similar between the treatments. The blood biochemical profile revealed no significant influence of the dietary treatments on hemoglobin, packed cell volume as well as serum levels of glucose, total protein, albumin, globulin, Ca, P, and alkaline phosphatase. Serum levels of the circulating thyroid hormones ($T_3$ and $T_4$) tended to be lower (p>0.05) on feeding of the LP diet besides showing an increasing trend with the advancement of age. Considering the similar performance and metabolic profile, it could be concluded that crossbred calves can be satisfactorily reared on 25% lower protein level as recommended by Kearl for developing countries, which would not only economize the cost of production but also help to reduce environmental pollution attributable to livestock production.

Due to the weight reduction and miniaturization of satellites, there is a growing interest in low-cost launch vehicles, which are cheaper to launch than larger launch vehicles. One of the most cost-effective ways to reduce the cost of launch vehicles is the reuse of vehicles. Most companies that are developing low cost launch vehicles are also adopting a vehicles reuse approach. Along with this reuse purpose, the demand for environmentally friendly space launch vehicles has increased, so the choice of fuel used for low cost launch vehicles has also become very important. Methane and hydrogen-enriched compressed natural gas (HCNG), which makes more energy-efficient by adding hydrogen to methane, are considered to be the most suitable when considering other factors such as energy density among the fuels that are eco-friendly and capable of reusing the launch vehicles. This study investigated the trends of low-cost launch vehicle and rocket fuel in the world as a reference for setting up domestic space development after the development of Korea Space Launch Vehicle-II.
