  • In information retrieval or digital library, one of the most important factors is to find out the exact information which users need. In this paper, we present an efficient index term extraction method which makes it possible to guess the content of documents and get the information more exactly. To find out index terms in a document, we use lexical chains. Before generating lexical chains, we roughly disambiguate the senses of nouns in a document using specific concept, called semantic window. Semantic window is that we look ahead semantic relations of peripheral nouns and disambiguate the senses of nouns. After generating lexical chains with sense-disambiguated nouns, we find out strong chains by some metrics and extract index terms from a few strong chains. We evaluated our system, using results of a key phrase extraction system, KEA. This system works in general domains of documents Including Information Retrieval and Digital Library.

  • This paper has surveyed above all what the patients call for physically, psychologically, and socially and researched how the ministers have acknowledge on cancers, their patients and hospice by means of enquete. To the difficulty the pastors should give their hands. This study researched what thoughts and behaviors the ministers actually had by the method of questionnaire. It was done from October 20, 1997 through December 10, 1997 on seven thousand of questionnaire paper of which 149 given back on the line of post or firsthandly were analyzed. The questioness consisted of 141 men(94.6%), 8 women(5.4) and 104 pastor on appentice(69.8%). There were 58 questionees(38.9%) who were hospitalized of their own diseases, and 121 questionees(81.3%) who had cancer patients hospitalized among their church people, relatives, or friends. Most of all the questionees(79.9%) had not any experience, such as they took some instruction about cancer patients. 72.5% of all the questionees had not ever served patients around them. The followings are the contents of the enquete: the questionees' view to chronic patients and death, where they put the priority in the case of that they look after patients who are under terrible pain ahead of death, what they think of such a situation as a patient has no technical possibility to be recuperated, why they think pastors do not like to visit chronics, which therapy they choose, whether they mainly control their pain or they do their best in order to heal their diseases, how much the questioned ministers know hospice, where and how they get the information on it, how much important role they play in the hospice team, whether the volunteers for hospice have not worked on account of pastors' misunderstanding to hospice service, whether the ministers want to take part in hospice service with their church people or not, and so forth. Suggestion: First, the education and P.R. about hospice are requested for the ministers. Second, the ministers must participate in hospice activities actively. Therefore the ministers and the churches must firsthandly take part in hospice activities beyond the education only and the raising of the recognition to them.

  • Purpose: This study attempted to determine intra-rater reliability and inter-rater reliability for measurement of foot form using the FPI-6 (Foot Posture Index) in patients with hemiplegia caused by stroke. Methods: Twenty two stroke patients were recruited into the research and their foot posture was evaluated using the FPI. Two raters assessed 6 items sequentially in accordance with the FPI-6 manual. This procedure involved asking the subject to take several steps in-place, prior to settling into a comfortable stance position with double limb support. Subjects were instructed to stand still with their arms by their sides and look straight ahead. FPI-6 values ranged from -2 to +2 for each of the six criteria and from -12 to +12 for the total score, indicating a position for each foot either along the supinated (negative score) to pronated (more than +6) continuum of foot posture. Results: The results showed that intra-rater reliability and inter-rater reliability for a total FPI-6 score was high: 0.807-0.888. An almost perfect agreement between the two raters was identified in the foot's morphological classification (Somer's D=0.712; p<0.05). Intra-percentage agreement was high (88.6%). Conclusion: The FPI-6 is a quick, simple, and reliable clinical tool with demonstrated good to excellent intra-rater reliability and good inter-rater reliability when used in assessment of the stroke patient's foot.

  • Homology searching on the primary structure (i.e., amino acid arrangement) of protein sequences is an essential part in predicting the functions and evolutionary histories of proteins. However, proteins distant in an evolutionary history do not conserve amino acid residue arrangements, while preserving their structures. Therefore, homology searching on proteins' secondary structure is quite important in finding out distant homology. In this manuscript, we propose an indexing scheme for efficient approximate searching on the secondary structure of protein sequences which can be easily implemented in RDBMS. Exploiting the concept of clustering and lookahead, the proposed indexing scheme processes three types of secondary structure queries (i.e., exact match, range match, and wildcard match) very quickly. To evaluate the performance of the proposed method, we conducted extensive experiments using a set of actual protein sequences. CSI was proved to be faster than the existing indexing methods up to 6.3 times in exact match, 3.3 times in range match, and 1.5 times in wildcard match, respectively.

  • In this paper, we present a register renaming method for conditional execution out-of-order instruction issue microprocessors. Register renaming method reduces false data dependencies (write after read(WAR) and write after write(WAW)). To implement a conditional execution out-of-order instruction issue microprocessor using register renaming, we use a register file which includes both in-order state physical registers and look-ahead state physical registers to share all logical registers. And we design an in-order state indicator, a renaming state indicator, a physical register assigning indicator, a condition prediction buffer and a reorder buffer. As we utilize the above hardwares, we can do register renaming and trace the in-order state. In this paper, we present an improved register renaming method using smaller hardware resources than conventional register renaming method. And this method eliminates an associative lookup and provides a short recovery time.

  • Modern Hanbok uses newly different color coordination based on traditional color coordination and symbolic meaning. Thus, this study would investigate the aspects of color coordination and symbolic meaning and present the characteristics of Hanbok as the data of corresponding period in the modern times. In order to investigate recent trend of preferred colors and color coordination of Hanbok, this study focused on the period of 2005~2010. When analyzing colors of Jegori(jacket), Wh, Y, B, YG, P and Gy series are shown in order. For trends for color of Chima(skirt), Pk, R, P, Gy and Bk series are shown in order. When you look into the color coordination of skirt and jacket on whole, color coordination of Pk-Wh represents the highest frequency. Color coordinations of Pk-Y, Pk-B, R-Y, R-G and Pk-G are followed in order. Color coordinations of R-YG, Bk-Wh, O-Y, P-Wh, Pk-YG, Gy-Y, R-Wh series and Gy-Wh are followed in order. When looking into characteristics of overall color coordination of Hanbok, it was shown that there were many opportunities to meet a variety of culture and various colors had emerged depending on individual taste and skin color in the modern times within the framework of basic colors of woman's 'Nokeuihongsang'(Green upper garment and red skirt) R-G, Y series, which are traditionally inherited. In addition, unlike existing traditional color coordination of five elements in the past, P, Gy and Bk series of color appeared in the skirt and Jacket. It could be affected by fashionable drama and films at that time and newly attempted colors ahead of fashion were reflected on the magazine. Therefore, it implied that it naturally gave new awareness of colors to the general public and the width of selection of colors became diverse.

  • Because of the size and environment in the shipbuilding process, the portable type robot is required for the automatic seam tracking. For this reason, the structure of laser sensor should be considered in the initial design step and the coordinate transformation between welding robot and laser sensor, which is joint finder, must be identified exactly and the real time tracking algorithm based on these consideration could be developed. In this research, laser displacement sensor in which its structure is laser beam's vertical projection, is developed to recognize the location of weld joint. In practical applications, however, images of weld joints are often degraded because of the surface specularity or spatter. To overcome the problem, the constrained joint finding algorithm is proposed. In the approach of coordinate conversion rule for the visual feedback control among welding torch, robot body and laser sensor is applied by the same reference point method. In the real time seam tracking algorithms we propose constrained sampling method which uses look ahead distance. The RLS(Recursive Least Square) filter is applied to obtain the smooth tracking path from the sensitive edge data. From the experimental results, we could see the possibility that the developed laser sensor with proposed processing algorithm and real time seam tracking method can be used as a welding under the shipbuilding condition.

  • Profit-keeping behaviors naturally occur in the market to satisfy consumers, and the logic behind it lies in the economies of scale. On the flip side, some commodities transacted in the market are not available or can not be easily acquired unless the demand is high enough. Under this proposition, some consumers rise and find their own solution to meet the services at a reasonable cost or at an adequate level. The commonly adopted way is to establish a cooperative, and it stirs purchasing power by pooling resources and further bargains price and service quality. As a consumer cooperative, housing cooperatives notably found in rural towns enable the elderly to continue independent living. This study is to take a closer look at residential life of the rural elderly in housing cooperatives. Utilizing in-depth focus group interviews with 40 residents in four housing cooperatives, this qualitative research draws main factors affecting the decision to move in, residential assessment, and strengths and weakness of living in a housing cooperative. The primary factor influencing the moving decision is to continue to independent living in a familiar community, and the bottom line is planning ahead. Frailty and bereavement are found to be the leading occasions for them to move. The participants are satisfied with the independent living arrangement, and particularly, cited such features as safety and security, elderly-friendly design, common spaces, freedom, social activities and efficient living. Also, it is stated that some cooperative natures such as control over the property and giving a voice on management render positive impacts on the satisfaction with communal living. In spite of all the benefits and strengths, participants face with a public notion that an independent living arrangement like a housing cooperative has never done before in rural towns, so that most people recognize it as part of dependent living arrangements like nursing home.

  • According to the Global Retail Development Index (GRDI) published by A.T. Kearney (2012), India is the $5^{th}$ most attractive retail destination in the world. The retail industry in India has been largely fragmented with small businesses dominating the retail landscape, with very few large players having multiple retail outlets. However, in the last few years, the industry has witnessed a significant growth in the number of large retailers having a chain of outlets across the country. This growth in the organised retail sector has driven primarily by large Indian retail organisations and conglomerates. With the government reducing the restrictions on foreign participation in Indian retail business by increasing the FDI cap on both single and multi-brand retail outlets, the industry is likely to see an explosive growth in the organised retail sector which accounts for only 8 percent of the total industry. With more foreign retailers poised to enter into the country, one of the key issues that the industry may face is finding the right quality of manpower. Literature suggests that in an industry which is characterised by players offering similar kinds of product assortments at similar price levels, success would be governed by the quality of service, which entails employees having the right skills and attitudes for offering quality service. Therefore, the two key issues that may be of importance for retailers are levels of skills and the motivation of the employees. However, according to the National Skill Development Corporation (NSDC, 2009), a significant skill gap exists in the industry, which may widen further in the years ahead, leading to greater challenges for organisations. This paper highlights some of the challenges and issues which characterise the industry in India, and suggests how companies could look at these challenges and seek ways to overcome these challenges.
