As the portable information appliance is developed, the demand of flat panel display equipments and parts are steeply increased. Most of all, the applications of LCD such as LCD TV, monitor, digital camera, CNS(car navigation system) and game machine become diversified. With the result that the number of BLU production enterprise is increased and the research on the design of backlight with the superior optical properties is persistently in progress. In this study we developed the pattern design tools for CCFL(cold cathode flourescent lamp) backlight to improve the conventional pattern design environment in which the pattern is designed manually from the experience and the trial and error. For the verification of our research, we designed the light reflection surface patterns for a real model of backlight and we measured the brightness uniformity using the BM-7. From the brightness uniformity measurement, the BLU designed using the presented tool showed the tolerable performance only in the first try of pattern design rather than the fifth try of pattern design in case of the conventional pattern design.

The childbearing process is not only a biological phenomenon of a woman who gives birth to a child but also a sociocultural phenomenon which is reflected on her value, belief in the sociocultural context according to social change and acculturation. The familial relation and sociocultural context in the multigravidas are more complex and intermingled than in the primigravidas. The purpose of this ethnographic research study was to explore the experience of identity from the first trimester of pregnancy to the third trimester of pregnancy in the Korean multigravidas and to understand deeply the perspectives of pregnant women reflected on Korean sociocultural values, beliefs, norms and familial culture. The participants of 10 pregnant women in Seoul, Korea were observed for 10 months from January to October 2000 and interviewed in their homes and comfortable place. Data analysis was accomplished 'line by line method' and significant concepts were classified according to themes, categories, and domains. The results of this study were as follows : The participants experienced 4 categorized subjects : understanding the oneself - mother to be, performing the dual role, drifting the emotion, and living disheartened during pregnancy. The participants were showed universality and diversity pattern in the self understanding process. The universal pattern were 'mother to be' showing maturation, life along family and priority on motherhood between being a mother and a woman. The diverse pattern were taking the dual role in working mothers having the higher self actualized value and personal identity rather than maternal identity, drifting emotion in resigned mothers, and living disheartened in mothers who have two daughters and no son. In conclusion, the Korean multigravidas experienced womanhood as well as motherhood through the self understanding process with familial connections during pregnancy. Therefore it is suggested that if the harmony and the balance between a mother and a woman is accomplished, the woman will lead a healthy and high quality of life. Also, this study sought to confirm the sociocultural factors affecting during pregnancy in the perspectives of the women with children. Therefore, the health care providers have to divert their attention from biomedical perspectives to biocultural perspectives integrating bio-psycho-sociocultural aspects of pregnant women in a clinical setting.

NPC in game is an important factor to increase the fun of the game by cooperating with player or confrontation with player. NPC's behavior patterns in the previous games are limited. Also, there is not much difference in NPC's ability among the existing games because it's designed to FSM. Therefore, players who have matched with NPCs which have the characteristics may have difficulty to play. This paper is for improving the problem and production and evaluation of the game NPC behavior model based on wolves hunting model in real life. To achieve it, first, the research surveys and studies behavior states for wolves to capture prey in the real world. Secondly, it is implemented using the Unity3D engine. Third, this paper compares the implemented state transition probability to state transition probability in real world, state transition probability in general game. The comparison shows that the number of state transitions of NPCs increases, proportions of implemented NPC behavior patterns converges to probabilities of state transition in real-world. This means that the aggressive behavior pattern of NPC implemented is similar to the wolf hunting behavior pattern of the real world, and it can thereby provide more player experience.

Clinical data about vocal nodules have seldom been reported, even though vocal nodules are commonly diagnosed in outpatient speech and voice clinic. This study aims to investigate clinical characteristics of the patients who are diagnosed with vocal nodules. This study analyzed the data for 10 years from the 319 patients diagnosed with vocal nodules (45 males and 274 females with the mean age of 39.4 ranging from 2 to 83) in terms of gender, age, occupation, voice change initiation pattern, change with time, throat clearing, smoking history, type of voice abuse, acoustic analysis, maximum phonation time, GRBAS, and VHI. Thirteen patients (4.08%) had unilateral vocal nodule and 306 patients (95.9%) had bilateral vocal nodule, the majority of which had a pattern of asymmetry (73.9%). The glottal closure pattern was hourglass in 72.1% of patients, posterior chink in 17.9% of patients, and irregular in 7.9% of patients. The most common occupational category was professional voice users (43.4%). The voice abuse pattern included excessive talking in 96 patients (76.8%), loud voice in 78 (62.4%) patients, and excessive singing in 17 patients (21.6%). The patients showed worse scores in G, B, and S than in R and A for the GRBAS evaluation. The most recommended treatment for vocal nodules was voice therapy. The current clinical data will be helpful for treatment planning for the patients of vocal nodule.

This study investigates the different pattern of trade negotiation between Korea and Japan. For the Korea, it is inevitable to enhance nation's competitiveness position amid the rapidly changed international environment. Especially, Korea's recent experience of IMF credit under economic crisis during 1997-1999 tells us the importance of international trade and trade negotiation. Our main interest is focused on the comparative pattern of both countries with the recognition that the role of the negotiation can not be overemphasized for the Korea. This is because Korea has continuously recorded the huge trade deficits with Japan for the long time. Although we consider the different degrees of products quality, industrial structure, productivity, and national competitiveness of both countries, it is necessarily required to pay special attention on different pattern of negotiation skills and tactics between two countries. In the paper, we suggest some important guidelines for Korea to improve its negotiation technique with Japan. First, valuing human relation between negotiators, rather than negotiating process. Second, preparing for negotiations: the negotiators should try to carve out enough time to prepare for the bargaining. Third, appreciating the power of patience: very essential to effective outputs. Fourth, being a specialist on both countries' culture and avoiding lawyers' intervention for conflict resolution.

This paper presents an effcient mobile multicast method using the user pattern. We exploit the repetitive movement pattern of mobile node to reduce the total number of experience of graft and join procedure. We defined the locality scope by a movement pattern. While the network is included in the locality scope, the network should maintain a multicast tree even when the mobile node moves to the other network. In this way, the mobile host can receive a multicast service without a delay when it moves to the network in the locality scope later. We compare our scheme with existing schemes under the total signaling cost and the service delay time by using a discrete analytical model for cost analysis. Analytical results demonstrated that the total signaling cost and service delay time was significantly reduced through our proposed scheme.

In recent years, several computer-aided pattern recognition and data mining techniques have been developed for modeling of soil behavior. The main idea behind a pattern recognition system is that it learns adaptively from experience and is able to provide predictions for new cases. Artificial neural networks are the most widely used pattern recognition methods that have been utilized to model soil behavior. Recently, the authors have pioneered the application of genetic programming (GP) and evolutionary polynomial regression (EPR) techniques for modeling of soils and a number of other geotechnical applications. The paper reviews applications of pattern recognition and data mining systems in geotechnical engineering with particular reference to constitutive modeling of soils. It covers applications of artificial neural network, genetic programming and evolutionary programming approaches for soil modeling. It is suggested that these systems could be developed as efficient tools for modeling of soils and analysis of geotechnical engineering problems, especially for cases where the behavior is too complex and conventional models are unable to effectively describe various aspects of the behavior. It is also recognized that these techniques are complementary to conventional soil models rather than a substitute to them.

Stress and fatigue are general physical aspects of our daily lives. It has been shown that physical therapists have different levels of job stress and fatigue according to the type A/B behavior patterns. This study collected data from 212 physical therapists between October 28 and November 23, 2016 using an anonymous, self-administered questionnaire. The study results showed the proportion of physical therapists with the Type A behavior patterns(TABP) was 18% greater than that of physical therapists with the Type B behavior patterns(TBBP). In this study, physical therapists with TABP were compared with physical therapists with TBBP. The results indicated that physical therapists with TABP were more inclined to experience higher levels of overall job stress and fatigue from the following stress factors: physical environment, job requirement, and job autonomy. Therefore, the stronger the tendency toward TABP, the stronger the feeling of job stress and fatigue from physical environment, job requirement, and job autonomy. Those with a tendency toward TBBP showed positive correlations between job requirement and the total job stress score; thus, the stronger the tendency toward TBBP, the stronger the feeling of overall job stress and fatigue from job requirement. This study suggests that it is necessary to manage the job stress and fatigue of physical therapists with both TABP and TBBP and to manage the job stress and fatigue of physical therapists with the type A behavioral pattern.

In domestic cases, the standard support pattern of 2-lanes road tunnels is presented because construction experience and high degree various data was abundant. But, it is not desirable to apply standard for 2-Arch tunnels that the precedent and measuring data is insufficient existing support pattern blasting plan and interpretation of separate way concerning specific terrain and rock quality. In this study, behavior according to load distribution ratio and Unsymmetrical Pressure about standard support pattern which is applied in design and construction of 2-arch tunnels was analysed and the examination of blasting vibration has influence on the center wall is conducted as a consequence reasonableness of support whether or not with presumed support pressure and ground reaction curve method. In result appropriateness of standard support pattern, support quantity is proper but considers specific terrain and rock quality condition when design and construction of further step 2-arch tunnel standard support pattern must be decided by considering terrains, soil properties and construction condition of the objective tunnel.

Objectives : The aim of this study was to develop a standard tool of pattern identification for chronic cough, which will be applied to clinical research. Methods : The items and structures of the instrument were based on reviews of textbooks and published literature. The advisor committee on this study consisted of 11 Korean respiratory internal medicine professors, one clinical fellow, and five clinicians with 10 years of experience. The questionnaire, which includes the signs and symptoms of chronic cough, was studied by the delphi method. Delphi examination was carried out via email, through evaluating the importance of symptoms included in each pattern. Results : We divided the pattern identification of chronic cough into five patterns: Wind-Cold, Phlegm-Turbidity, Liver-Fire, Lung Deficiency, and Kidney Yang Deficiency. By the Delphi method and a score evaluation, 38 items were chosen for pattern identification of chronic cough. Conclusions : Through this study, we created a Korean instrument for the pattern identification tool for chronic cough. We expect to apply this tool to subsequent research as its validity and reliability are further confirmed.
