Purpose: This study aimed to segment the home meal replacement (HMR) market among late middle-aged adults based on their food-related lifestyles and investigate the demographic characteristics cooking and food purchasing behaviors and HMR product purchasing patterns within these segments. Methods: An online survey was conducted among 395 individuals aged 50 to 64 years residing in Seoul. Factor analysis categorized their food-related lifestyles into health-seeking, novelty-seeking, economy-seeking, taste-seeking, and convenience-seeking. Cluster analysis identified three distinct segments: the dietary indifferent group, the dietary interested group, and the price-sensitive group. Results: Significant differences were found across these segments with respect to gender (p<0.001), monthly income (p<0.05), food preparation habits (p<0.001), food purchasing locations (p<0.01), and food purchasing costs (p<0.05). The three clusters also exhibited significant differences in HMR purchase frequency (p<0.001), reasons for HMR purchase (p<0.05), factors influencing HMR purchase decisions (p<0.001), HMR purchase locations (p<0.01), HMR expenditure (p<0.001), and factors contributing to HMR expenditure increases (p<0.001). Conclusion: Segmentaion strategies based on the food-related lifestyles of late middle-aged adults are crucial for successful marketing within the HMR market. Addressing these diverse needs through market segmentation research can lead to the development of better HMR products and services. Ultimately, this targeted approach will not only foster growth in the HMR market but also contribute to enhancing the quality of life for seniors in the future.

A finite element analysis has been utilized to analyze stress and strain fields and design a new configuration in orthopedics and implant dentistry. Load transfer and stress analysis at implant bone interface are important factors from treatment planning to long term success. Bone configuration and quality are different according te anatomy of expecting implantation site. The purpose of this study was to compare the stress distribution in maxilla and mandible accord-ing to implant length and bone engagement types. A three dimensional axi-symmetric implant model(Nobel Biocare, Gothenburg, Sweden) with surrounding cortical and cancellous bone were designed to analyze the effects of bone engagement and implant length on stress distribution. ANSYS 5.5 finite element program was utilized as an interpreting toot. Three cases of unicortical anchorage model with 7, 10, 13 mm length and four cases of bicortical anchorage model with 5, 7, 10 and 13 mm length were compared both maxillary and mandibular single implant situation. Within the limits of study, following conclusions were drawn. 1. There is a difference in stress distribution according to cortical and cancellous bone thickness and shape. 2. Maximum stress was shown at the top of cortical bone area regardless of bone engagement types. 3. Bicortical engagement showed less stress accumulation when compared to unicortical case overall. 4. Longer the implant future length, less the stress on cortical bone area, however there is no difference in mandibular bicortical engagement case.

The purpose of this research was to investigate effect of water extract of DangKwi-Eum-Ja ka Sumsoo(DESE) on the cytotoxicity of human epidemloid cell, A431 cells. The effects of DESE on the proliferation of A431 cells, Balb/c 3T3 cells, mouse thymocytes and splenocnes were estimated by MTT colorimetric assay, and nitric oxide production from mouse peritoneal macrophage was estimated by Griess method. DESE inhibited the proliferation of A431 cells at $10{\mu}g/ml$, and did not affect the proliferation of Balb/c 3T3 cells. DESE decreased the cytotoxicity of mitomycin C or cisplatin on A431 cells, increased the cytotoxicity of mitomycin C or cisplatin on Balb/c 3T3 cells. DESE inhibited the proliferation of mouse thymocytes and splenocytes at $100{\mu}g/ml$. DESE did not affect the nitric oxide production from mouse peritoneal macrophage in vitro, but decreased the nitric oxide production from DESE-treated mouse peritoneal macrophage.

This study was done to know the effects of Natural Ganoderma or Cultured Ganoderma on the innate immunities, tumor immunities and rosette forming capacities of spleen cells. The innate immunities were evaluated by measuring the effects of Natural or Cultured Ganoderma on the phagocytic activity and reactive oxygen intermediate(ROI) formation of macrophages. The effects of Natural or Cultured Ganoderma on the tumor immunities were evaluated by checking the antibody-dependent cellular cytotoxicity(ADCC) and natural killer(NK) cell activities. The administrations of both Natural and Cultured Ganoderma increased the phagocytic activities and the production of ROI of macrophages from the peritoneal cavities. But the effects caused by Natural Ganoderma were bigger than those by Cultured Ganoderma. Both the Natural and Cultured Ganoderma enhanced the ADCC but did not affect on the NK activity. The capacities of spleen cells to forming rosette were increased greatly bo the administration of Natural Ganoderma and slightly by the administration of Cultured Ganoderma. The results of this study showed that even though both Natural and Cultured Ganoderma enhanced the innate immunities, tumor immunity, and rosette forming capacity of spleen cells, Natural Ganoderma were better than Cultured Ganoderma in increasing the host's immune capabilities.

日本어린이의 運動生活습관에 미치는 옷을 얇게 입는 生活의 영향과 그밖의 環境要因에 의한 영향과의비교

荒木勉,崔正和 서울大學校 農科大學 1982 서울대농학연구지 Vol.7 No.1

"옷을 얇게 입는 生活→屋外에서 노는 시간의 연장→운동능력의 향상" 이들 관련성을 再확인 하면서 특히 "옷을 얇게 입는 生活→屋外에서 노는 시간의연장 "의 관련성에 관해 상세히 검토했다. 즉, 습관적으로 옷을 얇게입는 生活을 하고 있는 유차원 아동과 일반 유치원을 대상으로 屋外에서 노는 시간에 영향을 미친다고 생각되고 있는 지리적 한경, 양친의 운동생활 상황에 관해 앙케이트 조사를 함과 동시에 운동능력을 측정했다. 또 "옷을 얇게 입는 生活→屋外에서 노는 시간의 연장" 과의 관련성을 확인하기 위해 실제로 옷을 얇게 입혀 半年間이 縱斷的 추적을 했다. 더욱이 "옷을 얇게 입는 生活 →屋外에서 노는 시간의 연장 →운동능력의 향상" 과의 관련성이 국민학교 아동에 있어서도 확인할 수 있는지 여부를 검토했다. 얻어진 결과는 다음과 같다. (1) 薄着 유치원 아동은 일반 유치원 아동에 비해 가정에서 着依量이 적고 실외에서 노는 시간이 길며, 운동능력도 우월하다는 것을 인정할 수 있었다. 즉, "옷을 얇게 입는 生活→屋外에서 노는 시간의 연장→운동능력의 향상"의 관련성을 인정할수 있었다. (2) 薄着 유치원에 있어서는 일반 유치원에 비해서 일잔적으로 모친의 日常生活에서의 운동실시率, 父親의 과거의 운동 Club 경험을 및 가족이 함께 운동하는 率이 많은 경향이 인정되었다. 또 薄着 유치원 兒童은 노는 장소로서 빈터나 논밭, 일반 유치원 아동은 공원의 이용율이 높다는 것도 인정되었다. 그러나 幼兒가 屋外에서 노는 시간에 영향을 미치는 이들 각 조건의 영향은, 薄着에 의한 영향 만큼 크지는 않다는 사실도 인정되었다. (3) 실제로 薄着을 시작한 幼兒와 일반 幼兒에 관해 縱斷的으로 調査하면 屋外에서 노는 시간에 나타나는 兩 幼兒의 差異는 薄着을 시작한후 1개월 후부터 6개월 後에 현저하게 된다는 것도 인정되었다. 또 특히 男兒의 경우, 옷을 얇게 입는 生活을 계속함에 따라 운동능력의 증가율이 커진다는 것이 인정되었다. (4) 국민학교 아동에 있어서 "옷을 얇게 입는 生活 →屋外에서 노는 시간의 연장"의 관련성은 인정할 수 없었으나, "屋外에서 누는 시간의 연장 →운동능력의 향상"의관련성은 幼兒와 같은 경향을 인정할 수 있었다. (5) 이상의 결과로부터 노는 장소, 양친의 과거 및 현재의 운동생활 상황 등의 要因이 幼兒가 屋外에서노는 시간에 미치는 영향은 옷을 얇게 입는 生活의 경우만큼 현저하지는 않다고 推定된다. 즉, "옷을 얇게 입는 生活→屋外에서 노는 시간의 연장"의 관련성에는 옷을 얇게 입는 生活의 직접적 효과가 反暎되고 있다고 추측되어, 실천에 있어서도 薄着을 위한 考案 그 자체가 中心的 고제라고 생각된다. 국민학교 아동에 있어서는 薄着에 의한 영향과 그밖의 여러가지 환경조건에 의한 영향이 서로 相殺되고 있다고 생각된다. The childrens's out-door activities mean their extension of playing time outside the house and improvement of ability in sports. In this study the correlation between the extension of playing time and light wearing habits was intensively investigated. The comparison study of out-door activities was made between habitually light wearing kindergarden children and not light weareng children. Besides their outside house, a questionaire was made to find any relationship between playing time outside house, their parents out-door physical excercise and etc. Furthermore, to confirm the relation between light wcaring habit and longer playing time out-side house,a group of kindergarden children was selected for children to wear light clothing, and their activities were thoroughly checked for 6 menths. An attempt was made whether the relation mentioned above could be applied to elementary school children. The results are following as: 1) Children wearing light clothings had longer playing time outside house and better ability in sports than children who did not wearlight clothings. 2) For light wearing children their parents had experience in sports club activities. The playing area for the light wear children was any empty spaces including the farm field while other children played usually parks and regular recreational areas. However, these environmental conditions less affected their out-door playing time. 3) Form wearing light clothings, longer playing time outside house remarkably appeared in one to six months. For boys the light habits considerably improved ability in sports. 4) For elementary school children, the wearing habit did not have linearrelation of the extension of outside playing time, but longer playing time directly improve ability in sports.

한국 통역사들의 B언어 동시통역 현황

최정화 한국외국어대학교 통역번역연구소 2003 논문집 Vol.7 No.-

Unlike Western languages, there are no Western interpreters who can interpret from and into Korean. Consequently, Korean interpreters have no choice but to work in both directions. Several articles have already been written (Minns, 2002; Dejean, 2002; Lim, 2003) about the need to interpret into B. The author was interested in reviewing the current Korean market, to grasp the extent of interpretation into B as well as to see whether a correlation existed between being a competent professional interpreter and when the B language was acquired. A survey was distributed in December 2002 via e-mail to 80 members of the Korean Society of Conference Interpretation who have worked for at least two years as conference interpreters. The language combination covered are Korean-English, Korean-French, Korean-German, Korean-Spanish, Korean-Russian, Korean-Japanese, Korean-Chinese and Korean Among the various language combinations, it was found that the overwhelming majority of Korean-English interpreters (82.4%) had learnt English before puberty. Furthermore, it was found that they had studied an average of 4.7 years in an English-speaking country. When one considers that the respondents said that they worked an almost equal amount in both direction, the background of the interpreters strongly indicates that there is a correlation between the success of the interpreter and when the B language was acquired.
