  • Methoxy polyoxyethylene dodecanoate류($C_{11}H_{23}COO(CH_2CH_2O)_nCH_3$)는 고체촉매를 이용하여 지방산 메틸에스테르에 에틸렌옥사이드를 부가시켜 얻어지는 비이온성 계면활성제의 일종이다. 이들은 지방알코올을 이용한 비이온성 계면활성제 polyoxyethylene dodecyl ether류($C_{12}H_{25}O(CH_2CH_2O)nH$)보다 경제성이 높은 이점을 가지고 있다. 이 연구는 이들 두 종류의 비이온성 계면활성제에 대하여 비이온성 계면활성제/물/오일의 3성분계에서 일어나는 상거동에 관련된 오일의 가용화량과 phase inversion temperature(PIT)에서의 계면장력 및 세정성을 비교하여 methoxy polyoxyethylene dodecanoate의 세제용 비이온성 계면활성제로서의 적용 가능성을 확인하기 위해 수행하였다. Methoxy polyoxyethylene dodecanoate는 3성분계의 상거동에서 hexadecane에 대해 10~18%의 오일가용화량을 나타내므로서 polyoxyethylene dodecyl ether보다 약 6%의 높은 가용화력을 보여주었다. 또한, 각각의 PIT 조건에서 methoxy polyoxyethylene dodecanoate는 0.0124~0.0176 dyne/cm, polyoxyethylene dodecyl ether는 0.0130~0.0163 dyne/cm의 계면장력을 나타내었고 세정력에 있어서는 methoxy polyoxyethylene dodecanoate는 82.1~83.2%, 그리고 polyoxyethylene dodecyl ether는 78.5~80.4%로 methoxy polyoxyethylene dodecanoate가 polyoxyethylene dodecyl ether에 비해 높은 세정성을 나타내었다. methoxy polyoxyethylene dode-canoate의 우수한 세정 성능은 polyoxyethylene dodecyl ether에 비해 다소 높은 오일가용화력과 이에 관련된 PIT에서의 계면장력 저하효과에 기인된 것으로 판단된다.

  • The purpose of this study was to investigate the status of children's breakfast skipping and their mothers' needs for breakfast service at child care centers. A survey was conducted with mothers of children aged 3 to 5 years and attending child care centers in Gwanak-gu, Seoul. Out of 960 questionnaires distributed to the caregivers at 32 child care centers, 633 were returned (66% response rate), and 449 were analyzed (47% analysis rate) after excluding data from the respondents not meeting the selection criteria for this study: mothers of children aged 3 to 5 years. Over 2/3 (69%) of children ate breakfast every weekday (Breakfast Eaters) and almost 1/3 (31%) of children skipped breakfast one time or more often on weekdays (Breakfast Skippers). The collected data were compared between Breakfast Eaters and Breakfast Skippers. The average Good Dietary Practice Score of Breakfast Skippers was significantly lower than that of Breakfast Eaters, implying poorer dietary habits. A higher percentage of mothers of Breakfast Skippers (62%) responded that breakfast service was 'necessary' or 'very necessary' at child care centers than those of Breakfast Eaters (27%). A multiple logistic regression analysis was conducted to determine factors affecting mothers' needs for breakfast service at child care centers. The result showed that the children's ages, mothers' occupational status, household monthly income, frequencies of eating breakfast on weekdays and satisfaction level with morning snack provided at child care centers affected mothers' needs for breakfast service at child care centers. In particular, mothers who had a full-time job (OR = 2.06) than housewives, mothers whose children did not eat breakfast at al (OR = 3.54), ate $1{\sim}2$ times (OR = 5.50) or ate $3{\sim}4$ times (OR = 3.80) on weekdays than those whose children ate breakfast every weekday were more likely to have needs for breakfast service at child care centers than housewives. In conclusion, Breakfast Skippers tended to have poorer dietary habits than Breakfast Eaters and Full-time working mothers had higher needs for breakfast service at child care centers. This study results suggest that child care centers consider serving breakfast to children as the number of working mothers increases.

  • This study was carried out to investigate the changes of rural residential environmemts accompanied by the rural village improvement projects. The results of this study can be a guidoline for further betterment works of rural village envirnments. This sutdy is composed of the survey of two major parts, one Is the interview of the residents and the survey of existing conditions of residential environments, and the other is a questionnaire survey of the mental image, preference and satisfaction for each village residential environments. Based on preliminary investigation, five rural villages, located In Kyungsamgun., Kyungbuk province, were selected as sutdy sites. The major results are summarized as follows; 1. In socio-cultural enveronments, the ratio of compound and non - agricultural household are increased with the modernization of rural villages. On the ocher hand, the numbers of neighbor's association are considerably decreased. This means the traditional community of korean rural villages are diminishing. 2. In physical environments, the ratio of improved western type gouses are increased In modprnized villages. And the modernization is most remarkable in the palls of fences and gardens. 3. By the result of the analysis of residfnt's environmental image and preference, the image scores of urban, formal, mdoern, etc. are showed to be high. And the preference is also high in modernized villages. But in general, the Preference for the village environment is comparatively low in all villages. This means the improvememt work should be continuous and systematic. 4. By the result of stepwise regression analysis, the variables, affecting the preference of village environment. are regularity, familiarity, amount of greenery, beauty of surrounding scenery, convenience, cleanness, etc. The R2s of the perference models were 0.4486 ∼0.9395, Which are considered to be high. 5. In the satisfaction for each residences, the toilets are mostly dis - satisfying. With the modernization of vilelages, the needs for environmental quality by residents are increased. 6. In the satisfaction for village enveironments, the satisfaction level is most low in service facilities, such as public bath, barbershop. And the satisfaction for the scenic beauty, the amenity of surrondings, and the com munity of the traditional villages, are commparatively high in conventional villges. 7. The imporvement works, based on the characteristics of each rural villages, are recommended. And the tradition of Jung - ja tree spaces and harmony with surrounding landscape of traditional villages, must be conserved with good regards.

  • 취업 중 자영업이 차지하는 비중이 상당함에도 불구하고, 자영업 선택의 결정요인에 대한 연구는 일천하다. 특히 여성에게 있어 결혼과 자녀 보육이 취업에 장애요인으로 작용하는 현실을 고려할 때 상대적으로 근로시간의 선택이 자유로운 자영업은 여성의 가사노동과 경력 유지를 병행하는 하나의 대안이라 할 수 있다. 본 연구는 여성의 취업 미취업의 선택과 피고용 자영업의 선택을 동시에 고려하는 이변량 프로빗 모형(bivariate probit model)을 "한국노동패널" 1차년도(1998) 자료에 적용하는 한편 취업한 여성을 3차년도(2000)까지 추적하여 이 기간 중 발생한 노동공급의 변화-노동시장에서 퇴장, 근로시간 증가, 근로시간 감축-의 결정요인을 다항로짓 모형(multi-nomial logit model)을 이용하여 분석한다. 취업의 선택에서 어린 자녀의 존재는 유의한 부(-)의 효과를 갖은 반면 자녀 보육 보조자의 존재는 유의한정(+)의 효과를 갖는 것으로 나타나며, 자영업의 선택에서 자녀의 존재는 정(+)의 효과를 가지나 통계적으로 유의하지는 않게 나타난다. 결혼과 어린 자녀의 수의 증가는 노동시장에서의 퇴장에 유의한 부정적 효과를 미친 반면 근로시간의 감축에는 유의한 효과를 미치지 않는 것으로 나타난다. 임금근로자와 비교할 때, 피용자가 없는 자영자와 무급가족종사자는 근로시간 증가보다는 노동시장 퇴장에서 퇴장하는 확률이 낮고 피용자가 없는 자영자는 근로시간을 감축하는 확률이 낮은 것으로 나타난다. 근로시간의 유연성으로 가사노동과 시장노동의 병립이 용이한 자영업을 잠재 여성인력의 활용과 경력단절을 막는 방안으로 고려하는 정책적 함의를 갖는다.

  • To prepare for the changes in the future, this study considered people in their seventies and eighties in rural areas in the last decade. Based on a survey of rural life by the Rural Development Administration, all factors were analyzed using SAS ver. 9.3. The rate of rice farming decreased, and vegetable-cultivation increased from 8.4% in 2001 to and 26.6% in 2008 for people in their seventies and eighties. The number of family members decreased to 1.96 in 2010 from 2.04 in 2001, and annual income increased by KRW 20-29 million for those in their seventies and eighties, whereas it was more than KRW 30 million for those in their forties. Bathing with warm water increased to 88.9% from 69.8%, and household waste treated by self-incineration decreased from 86.4% to 40.0% in the last decade. Separate collection spread since 2008. Food waste disposal and the burial (46.0%) showed had for people in their seventies and eighties, and animal feed increased (50.7%) for those in their forties at 2001. The separate collection increased by 39.6% in 2010 for those in their seventies and eighties and by 53.5% for those in their forties(p<0.05). The manufacture of jang and kimchi showed were little annual changes for people in their seventies and eighties. Food storage processing was higher for those in their forties. For those in their seventies and eighties, food group intake over the 2004-2010 period increased from 3.3 times a week to 4.2 times a week for protein foods and from 4.9 times a week to 5.5 times a week for vegetables. There was no change in fruits, milk, and seaweeds for those in their seventies and eighties, but there was an increase for those in their forties. The results suggest the continued increase in the manufacture of jang and kimchi and protein and vegetable intake for those in their seventies and eighties. Some direction to welfare, mechanized rice planting and living with neighbors together would be continued with good nutrition for elderly residents.

  • 김치는 우리의 전통식품으로서 가정마다 독특한 김치맛을 이어왔으나 최근 산업화와 주거환경의 변화 등으로 사먹는 김치의 수요가 늘고 있고 점차 레시피의 다양성을 요구하는 시대가 되었다. 그 지역의 기호에 맞는 김치를 표준화시키기 위해서는 지역민의 기호를 파악하고 이에 맞는 제품을 개발하는 것이 요긴하다고 생각된다. 따라서 지역의 특성에 맞는 고급김치를 개발하기 위하여 부산 및 부산인근의 예로부터 김치맛으로 유명한 명가김치들을 발굴하고 이를 현대화할 필요성이 높다. 따라서 이의 발굴을 위해 부산대학교 김치연구소내에 명가김치 선정위원회를 구성하고 여러 채널을 통해 9종의 통배추김치의 레시피를 발굴하였고 이를 공장김치나 문헌상의 김치의 레시피와 비교해 보았다. 이들의 통배추김치의 레시피상의 특징은 고춧가루, 마늘, 젓갈의 사용량이 많았고 젓갈은 대부분 자가의 멸치젓을 사용하고 있어서 맛이 진하고 매운 남부지방 김치의 특성을 나타내 주었다. 생선류와 청각 같은 해산물의 사용이 많았던 것도 중요한 특징으로 여겨진다. 다량의 고추가루를 개기 위하여 멸치 우린물이나 새우 우린물, 배ㆍ무ㆍ양파 즙을 사용하였고 찹쌀풀을 넣어 맛을 부드럽게 하였다. 재료의 선정에 매우 신경을 써서 좋은 배추를 구매하고 있었으며 고추가루는 색깔을 중시하여 태양초를 선호하였고 풍부한 고명의 사용도 명가김치로서의 품위를 높이는데 소중한 역할을 하고 있음을 알았다. 절인배추 1000 g에 대한 부재료의 비에서 명가김치와 타김치와의 차이가 확실하여 김치에 첨가하는 부재료들의 다양성과 함량이 김치의 맛과 품위를 높이는데 결정적으로 기여함을 알 수 있었다. 염농도는 일반적으로 알려져 있는 남부지방 김치의 특징인 짭짤한 김치는 많지 않아서 2% 부근의 슴슴한 김치가 많았고 이는 소량의 김치담그기, 냉장고의 일반화 및 저염화의 경향 등으로 설명할 수 있겠고 특히 대부분의 조사대상들은 김치의 소금절임 과정을 대단히 중시하여 슴슴하게 소금절임하는 것이 배추의 아삭아삭한 조직감을 유지하는데 중요함을 알고 있어 김치의 염농도와 조직감에 관한 연구가 계속되어져야 할 것으로 보였다.

  • 일반적으로 고밀도 도시는 더 많은 접근성도 높고, 다양한 교통시스템을 운영한다. 그러나 반대로 차량 속도도 늦고 통행 비용이 많이 들기 때문에 가구 당 년간 평균 차량주행거리는 상대적으로 적다. 결국 도시압축도가 높은 도시일수록 교통수요가 작아지는 현상이 나타난다. 오늘날 각국의 토지이용계획에서는 압축도시를 지지한다. 상당한 논쟁에도 불구하고 압축도시는 지속가능한 도시화의 중요한 대안으로 간주된다. 본 연구의 목적은 도시압축도가 높을수록 교통수요를 줄일 수 있는지에 대하여 실증적으로 규명하는 것이다. 이를 위해 본 연구에서는 서울시의 각 동(dong)간의 도시압축도와 통행발생에 미치는 영향을 분석하고자 한다. 특히, 대도시 통행발생의 근원이 되는 출근통행을 대상으로 한다. 혼합용도, 이용 패턴을 고려한 서울시 424개의 동을 육각 다이어그램으로 나타내었다. 가구 수와 제조업, 상업/서비스업 종사자 수 간의 상대적인 편차를 근거로 존의 통행발생율에 대한 도시압축도의 효과를 분석하기 위해 다중선형회귀 모형을 개발하였다. 결과적으로 주거밀도와 혼합용도지역의 통행발생율이 비교적 낮은 것으로 나타났다. 더욱이 압축지역의 사람들은 타 지역에 비해 대중교통 이율이 높은 경향을 보였다.

  • This study conducted surveys on perception and utilization of Korean soybean paste targeting 493 women from their 20s to 60s residing in Daegu. Most subjects married (75.3%), were part of a nuclear family (84.8%), had more than a high school diploma (95.8%), had a career (47.9%), lived in an apartment (68.4%), had a total household income of 5 million won or more (38.1%), and had monthly food expenses more than 0.5 million won and less than 1 million won (42.2%). Regarding perception, 'rich nutrition' was the most commonly held perception in subjects in their 60s (4.4), followed by 'good taste' in subjects in their 40s (4.3). Regarding reasons for consumption 'healthy' was highest in subjects in their 60s (47.3%) and 40s (45.6%) and 'delicious' in subjects in their 20s (56.1%). Regarding how to make it, subjects in their 60s responded 'know for sure' (57.1%), while only 2% of 20s responded the same. Subjects in their 50s and 60s had a higher ratio of answering 'know' while 20s and 30s 'don't know', For preparation methods, subjects in their 20s (53.1%) and 30s (41.4%) answered 'buy at the market', subjects in their 40s (68.9%) 'get from family or relatives' and subjects in their 60s (47.3%) 'make by one's own'. For preservation method, subjects in their 20s and 30s answered 'preserve in refrigerator', the 60s tend to answer 'preserve in jangdokdae'. Buying at the market was most common in subjects in their 20s (36.1%) and 30s (28.5%) and the reason was 'convenient' (39.6%). The place of purchase was 'in large supermarket or department store' (78.5%). For the future consumption pattern, 'increase in consumption of commercialized product (44.0%)', subjects in their 60s answered 'keep making at home' while subjects in their 30s and 40s answered 'keep making at home or buying product half and half'. According to the above study results, women living in Daegu region were aware of excellence of traditional soybean paste. However, due to changes in residential circumstance and lack of knowledge about the recipe, they did not make. They receive soybean paste t from family, relatives or bought in the market, which indicates the continuous decrease in home-made soybean paste. Therefore, due to the expanding social participation of women, the product market is expected to increase. I think it is important to develop traditional commercial soybean paste in the traditional way to improve the traditional flavors.
