This study was conducted to examine the effects of a healthy dietary life and purchase of environmental-friendly food materials according to a mother's lifestyles of health and sustainability (LOHAS) attitudes. The subjects consisted of 295 mothers. The findings are summarized as follows. The mother's LOHAS attitude index averaged 3.39 points out of 5 points. High LOHAS attitude items were "I participate actively in separating the trash collection" (4.16 points), and "I recycle dresses that I do not wear by taking them to the recycling center" (4.08 points). In contrast, LOHAS attitude items for "I do community service activity on the weekend" (2.57 points), and "I try to serve in the local community" (2.63 points) scored very low. A high LOHAS behavior index occurred for mothers who were "resource saving", whereas "social welfare" scored low. Mother's intention to purchase environmental-friendly food materials averaged 3.61 points. Mother's health dietary life attitude score averaged 3.52 points. When age, monthly income, and the environmental-friendly food materials purchase ratio of the mother was high, the health dietary life performance was high. The LOHAS attitude index of mothers had an impact on the purchase intention of environmental-friendly food materials in resource saving and environmental-friendly oriented propensity groups. The LOHAS attitude index of mothers impacted healthy dietary life in environmental-friendly, family and health oriented propensity groups.

This study examined how the households used and combined financing sources to pay for college education. It compared the probability of using each source (current incomes, saving, education loans and grants) by households' socio-economic characteristics and analyzed which factors influence the decision to use each source and the amounts from each source for financing college education. Data for this study were from a questionnaire completed by 4-year college students (n=623) and were analyzed by t-tests, ANOVA and Heckman's two-step estimation models. The findings of this study were as follows: First, the most frequent source for college education was parents' savings and the second one was parents' incomes. Also, the most frequent combination of sources was saving and current incomes and the second was combination of three sources, saving, incomes and education loans. Second, the probability of using incomes was higher for younger students than for older students. The number of siblings showed significant differences among income, savings and education loans. Those who had higher incomes were more likely to use current incomes, saving, but less likely to borrow for financing college education. Middle-class income groups were more likely to borrow for education. Third, household incomes and asset holdings had generally positive impacts on the probability of using incomes and savings for college education, while total debt burden decreased both the probability and amounts of income and saving sources. The college costs had significantly positive effects on both the probability and the amounts of all of financing sources. Total grants received significantly decreased the amounts from incomes, savings and borrowing sources.

Common LED (Light Emitting Diode) lamp has many advantages to compare with fluorescent lamp, long life and no pollution matter like the mercury. The LED lamp is a good light source especially for shipboard lighting because of its compact structure which prevents explosion and shock. Also, low maintenance cost is expected due to its longer life time in comparison with conventional lamps. The LED lamp, however, need some estimates that change of voltage and frequency, vibration, moisture on board to definite accommodation of the LED lamp to shipboard. The purpose of this study is to compare physical properties of a fluorescent lamp with one of the common LED lamp so as to analyze accommodation of common LED lamp on board. This study was carried out in two stages. First, temperature, humidity of illumination, voltage, electric current, frequency and electric power were measured by using experimental equipments. Second, a comparative analysis of consumption electric power, annual oil charge, annual CO2 emission and lamp life time, etc of the fluorescent lamp and common LED one was made. As a result of the study, the consumption electric power of fluorescent lamp was 50% higher than one of the common LED lamp. As a result of measuring life time, it was found that life time of common LED lamp was more about 3.5 fold than one of the fluorescent lamp. Considering these results, it's thought that common LED lamp is verified that energy saving is possible and using is possible as substitute for fluorescent lamp on board.

The purpose of this study is to investigate the sages’ philosophic view of home economic management in Chosun dynasty. The research method is to review literatures such as Jangbosanrimkongje, Songhosasal, Sasojul, Nehun, Geneusa, Mocminsimsa and Dasanmusun. The major points of this study were as, 1) Sages mastered that the primary principle of home economic management is to control the material desires. 2) Sages believed that home life management is required the lowest materials, and those materials enough are able to obtained through diligence, frugality, thift and savings. Therefore Sages advised us that each of us lives a diligent, frugal, thrifty and saving life.

본 연구의 목적은 이용자가 공공도서관을 통해 받는 혜택이 무엇이며 얼마나 누리고 있는가를 설명하기 위함이다. 주로 국외 문헌을 통해 밝혀진 공공도서관의 혜택을 국내 도서관 이용자의 시각에서 재조명하고 해석하며 혜택의 수혜 정도를 도서관 이용자 측면에서 살펴보았다. 이를 위해 S도서관 이용자를 대상으로 도서관 이용으로 인해 얻는 혜택과 그 수준을 측정하였다. 개방형 질문지를 통해 자유롭게 기술된 이용자의 응답을 키워드로 추출하여 혜택의 유형과 내용을 파악하였고 향유지표를 기반으로 한 13개 혜택 항목을 통해 혜택의 수준을 파악하였다. S도서관 이용자들은 도서관 이용으로 독서, 경제적 이익, 개인적인 충족, 위안, 평안, 만족감 순으로 혜택을 인식하였다. 향유결과지표를 통해 본 이용자의 혜택 수준은 더 많은 독서(4.31)와 경제적 이익(4.14)이 가장 높은 것으로 나타났다. 이러한 혜택은 성별과 학력별로는 차이를 보이지 않았고 연령대와 직업별로는 혜택의 수준이 다양하게 나타났다. 가족간의 유대, 아이의 독서, 문화를 즐김, 업무능력의 향상과 같은 혜택이 연령대별로 차이가 나타났고 경제적 이득에 대한 혜택은 주부와 취업준비생과 같은 비경제활동 인구가 가장 많이 받고 있는 것으로 나타났다.

펠렛종자를 점파용 파종기로 이용하여 기계화 정밀파종 함으로써 나종자를 손 작업에 의존하여 파종하는 것보다 파종시간과 솎음시간을 각각 225시간 및 460시간 절감할 수 있었고, 종자량도 72% 절감 할 수 있었다. 인력에 의한 손 파종은 파종과 솎음작업에 1 ha당 720시간이 소요되었으나, 펠렛종자를 이용한 기계화 파종은 35시간에 불과하였다. 따라서 펠렛종자를 기계화 파종함으로써 나종자를 인력에 의존하여 파종하는 관행방법에 비해 파종과 솎음작업의 생력효과를 95% 이상 높일 수 있었다. 펠렛종자의 묘출현율은 무처리 종자보다 출현율이 8% 정도 낮았고 출현속도도 약 1.9일 정도 지연되었으나 35일 경과된 유묘의 초기생육에는 큰 차이가 없었다. 유묘출현 반응은 품종에 따라 약간의 차이는 있으나, 펠렛종자는 나종자나 SMP 처리종자에 비해 출현율이 저하되었고 출현속도도 늦었다. 그러나 SMP 처리하여 종자활력을 증진시킨 후 펠렛하면 출현율도 향상되었고, 묘출현속도도 1일 정도 빨랐다.
