This study was performed to offer the basic data for the design of farm shoes. 265 Korean female farmers aging between the 40s to the 80s volunteered for this study and we measured 40 items on each foot with the 3D foot scanner. First, the differences between farmers' feet and non-farmers' feet were analyzed. Farmers' feet were thicker in the instep areas, but had lower arch height than non-farmers' feet. In addition, farmer's feet were tilted to the inside. Next, eight factors were extracted among the 40 measuring items, and the classification criteria of the foot shape was analyzed. The important factors were: size of foot length and volume of ankle, malleolus height and size, volume of the front part of ankle, medial & lateral ball width, and vertical size of foot. Third, three clusters according to the foot shapes were categorized by cluster analysis of eight factor scores. Foot type 1 was medium in foot length, big in thickness, large in lateral ball width, small in toe 1 angle, and tilted to the inside. Foot type 2 was long and slim, and big in toe 5 angle. Foot type 3 was short in foot length, medium in volume of the front part of ankle, large in medial ball width, and big in toe 1 angle. Despite its shortness, foot type 3 was thick and showed severe deformation in toe 1. Lastly, the frequency distributions of the foot types in each age group were analyzed. Female farmers of the forties showed high frequency in type 1 and other age groups showed high frequency in type 2. The older female farmers showed higher frequency of type 3.

The relationship between household attributes and trip generation can only be found in Seoul Metropolitan Household Travel Survey, which has been implemented every 5 years. However, various household attributes' impact on trip generation has not been analyzed closely. This paper compared and analyzed those impact. The results could be useful when trip generation models are studied in the future. They are as follows. The household size should be an important classification criteria when household trip generation is estimated. The traditional assumption that the relationship between household auto ownership and trip generation is positive and linear correlation should be reconsidered. Weekday travel data only did not showed that housing type has an influence on trip generation. Household income is unrelated with trip generation among single-person household, while multi-person household is related strongly. However, when trips are classified by purpose, impact of household income on trip generation are varied by trip purpose. Especially, the increase in single-person household can not be overlooked when trip generation is forecasted.

Background and Aim: The incidence of extra nodal non Hodgkin lymphoma (ENL) is rising throughout the world. However, data regarding ENL as a group is limited. The aim was to study the epidemiological and histomorphological trends of primary ENL (pENL) in India. Material and Methods: The biopsy materials from sixty eight patients with pENL (45 male, 23 female, M:F= 1.9:1), diagnosed over a five year period (2005-2009), were analysed and pathologically reclassified according to the World Health Organization (WHO) classification, 2008 criteria. Results: Primary extra nodal non Hodgkin lymphomas constituted 22.0% (68/308) of all non Hodgkin lymphomas (NHL). The mean age at presentation for pENL and primary nodal NHL was 43 years and 58 years, respectively with a male predilection (M: F=2:1). Central nervous system (CNS) constituted the most common extranodal site (20/68, 29.5%) followed by gastrointestinal tract (17/68, 25%), and nose/nasopharynx (8/68, 11.8%). Diffuse large B-cell lymphoma (DLBCL, not otherwise specified), extranodal marginal lymphoma of mucosa associated lymphoid tissue (MALT) type, and B cell NHL unclassified (U) were the three most common histological types observed. T-cell phenotype was rarely noted (4%). Follicular lymphomas and anaplastic large cell lymphoma, seen among nodal NHL, were absent at extra nodal sites. Majority (41/68, 60%) of the patients with pENL were immunocompetent and 55% were in stage I-II with favorable prognosis. Conclusion: Central nervous system was the most common site of ENL, followed by gastrointestinal tract. Majority of pENL occurred in immunocompetent hosts with a favorable prognosis.

Gene expression profiling (GEP) has identified several molecular subtypes of breast cancer, with different clinico-pathologic features and exhibiting different responses to chemotherapy. However, GEP is expensive and not available in the developing countries where the majority of patients present at advanced stage. The St Gallen Consensus in 2011 proposed use of a simplified, four immunohistochemical (IHC) biomarker panel (ER, PR, HER2, Ki67/Tumor Grade) for molecular classification. The present study was conducted in 75 newly diagnosed patients of breast cancer with large (>5cm) tumors to evaluate the association of IHC surrogate molecular subtype with the clinical response to presurgical chemotherapy, evaluated by the WHO criteria, 3 weeks after the third cycle of 5 flourouracil, adriamycin, cyclophosphamide (FAC regimen). The subtypes of luminal, basal-like and HER2 enriched were found to account for 36.0 % (27/75), 34.7 % (26/75) and 29.3% (22/75) of patients respectively. Ten were luminal A and 14 luminal B (8 HER2 negative and 6HER2 positive). The triple negative breast cancer (TNBC) was most sensitive to chemotherapy with 19% achieving clinical-complete-response (cCR) followed by HER2 enriched (2/22 (9%) cCR), luminal B (1/6 (7%) cCR) and luminal A (0/10 (0%) cCR). Heterogeneity was observed within each subgroup, being most marked in the TNBC although the most responding tumors, 8% developing clinical-progressive-disease. The study supports association of molecular subtypes with response to chemotherapy in patients with advanced breast cancer and the existence of further heterogeneity within subtypes.

Objectives : This study is to propose discriminative keys with stereoscope for minute seed herbs easily mixed up, but hard to discriminate by naked eyes: Alli Tuberosi Semen(ATS)✳Alli Fistulosi Semen(AFS), Malvae Semen(MS)✳ Abutili Semen(AS), Plantaginis Semen(PS)✳Schizonepetae Semen(SS).Objectives : We reviewed the description of original plants and medicinal herbs from literature. The specimen of original plant were collected, determinated and compared to samples in the market. Primary classification was performed with naked eyes. and we found out other discrimination keys for non-distinctive herbs with stereoscope. Discrimination keys were set as the morphological criteria of authentic herbs, percentage of adulteration, and standards for discriminating genuine herbs from adulteration.Results : 1) ATS is bigger, has reticulate pattern on protuberant side and unique garlic chives taste. AFS which is usually mixed up, is smaller, has 1~2 ridges and unique welsh onion taste. 2) MS is smaller, has no villus, but its length of bumps are similar. AS easily mixed up, is bigger and has white villus. Its upper side bump is longer and more sharp. 3) PS has dent at middle of the back side. It becomes very sticky when it is put or boiled in water. SS which can be mixed up has no dent and low viscosity compared to PS.Conclusions : With this result, we propose discriminative keys which can identify the original plants and processed herbal state of six herbs. Because minute medicinal herbs are hardly distinguishable by sensory test, It is essential to differentiate by using stereoscope.

Due to recent change in fire stations, this study aims to propose improved directions for planning of 119 rescue centers through its analysis of spatial organization and characteristics by functional area based in case studies of new-design centers. The Korean 119 rescue centers have changed in terms of function and roles in line with the flow of changing social environments, so it has been required to give new spatial change to these centers. It's meant in this study to classify compulsory special service spaces for the 119 rescue centers by domain and to suggest design guidelines for each type of spaces. Eight case of recue centers that were newly built in and after 2008 were selected and analyzed to serve the purpose. Finally, the results of this study were as followed: First, each of the rescue centers is divided into several domain depending on the type of work, and there are meaningful characteristics in the vertical and horizontal spatial layout of the individual spaces. Second, there are specific differences among the spaces in the spatial occupation percentage. The percentage of the space for community service is obviously lower in the 119 rescue centers in Seoul than in Incheon. Third, the domain classification criteria of this study are selected based on earlier studies, and another space for community service is newly added as a result of making a case study.

One of the most pronounced phenomenon among the changes in the 1990s' Korean labor market is the growth of the share of temporary and daily workers. Yet, it is still not clear exactly how the phenomenon should be interpreted. In order to look into the phenomenon, the paper introduces various definitions of employment status based upon multi-dimensional classification criteria and estimates their sizes using the EAPS Supplemental Survey of August 2000 by the National Statistical Office of Korea. According to the data set, the share of temporary employment by the OECD standards is 17.6% which is higher than most European countries but not far away from them unlike some popular claims. Further, it is shown that the high proportion of temporary and daily workers among the employees, currently above 50%, is possibly due not only to the increased employment instability but also to the widened differentiation among workers in terms of fringe benefits such as the retirement pay and social insurances.

Recently, virtual reality contents are being experimented and introduced in various fields such as game, education, medical, exhibition, movie, SNS. However, research on virtual reality is mainly focused on industrial and technological perspectives, so contents-centric or contents-oriented research is on virtual reality is very rare. In order to prepare for the future of virtual reality properly, content-oriented research is very much needed. The purpose of this study is to investigate the types, characteristics, and possibilities of virtual reality contents applied to theme parks. For this purpose, we tried to classify the contents type of virtual reality based theme park. The criteria of type classification are divided into 'fixed type', 'continuous moving type', and 'segmented moving type' according to the player's position movement possibility and movement type, here we combine the senses such as tactile, taste, smell, balance etc.

The purpose of research is to examine mothers with elementary school children in Chungcheong and the convergence effect of recognition of food labeling standards on purchasing behavior. A two-step cluster analysis was performed for group classification according to the purchase behavior of processed foods and the collection was determined by Schwarz's BIC criteria. Three types were determined: "convenience pursuit," "large mart preference," and "high cost reverse purchase". The proportion of college graduates in 'large mart preference' was higher, the proportion of employment mothers in 'high cost reverse purchase' was higher, and the need for food labeling standards was higher in 'large mart preference'. 'Shelf life' was recognized as the most important item. 'Large market preference' scored higher in 'used materials' and 'food additives', 'nutrition labelling'. In order to improve the purchasing behavior of processed foods, above all else, it is necessary to develop customized educational media that can be easily applied to real life.
