본 연구는 할머니의 양육경험을 자녀 세대와 손자녀 세대 중심으로 살펴보고자 하였다. 이를 위해 자녀 세대와 손자녀 세대의 양육을 경험한 세 할머니를 대상으로 심층면담을 통하여 분석하였다. 연구결과 할머니의 양육경험은 양육 환경의 변화, 양육 문화의 변화, 양육가치관의 변화로 크게 3가지 범주로 나타났다. 구체적으로는 양육 환경의 변화는 '혼자 하는 양육에서 성인 자녀와 함께 하는 양육으로', '체력으로 이겨낸 양육에서 체력이 달리는 양육으로' 으로 나타났다. 양육문화의 변화에서는 '전통을 답습하는 양육에서 시대의 흐름을 따라가는 양육으로', '보편적인 양육에서 차별화된 양육으로', '계획되지 않은 양육에서 계획된 양육으로' 으로 나타났다. 마지막으로 양육가치관의 변화에서는 '무조건적 사랑의 양육에서 사랑과 훈육이 조화된 양육으로', '학습최우선의 양육에서 건강최우선의 양육으로', '조바심 내는 양육에서 기다려주는 양육으로' 으로 나타났다. 이러한 결과는 양육 환경, 양육 문화, 양육 가치관에 따라 과거와 현재를 양육하는 할머니의 양육경험이 변화되고 있음을 시사해준다.

본 논문에서는 u-IT기술을 농업에 적용하여 시설하우스 식물들에게 최적의 생장 환경을 자동으로 조절하는 시스템을 제안한다. 본 시스템은 온도, 습도 등의 환경 센서와 EC, PH 등의 생체 센서 그리고 자동제어장치들로 구성되어 있고, 이는 자동조절 소프트웨어로 제어된다. 농민은 이 시스템을 기반으로 시설하우스의 생장환경을 정밀하게 제어하여 생산비를 절감하고 고품질의 농산물을 생산하게 된다. 본 시스템은 각 시설하우스에 설치되는 클라이언트 시스템과 클라이언트의 데이터를 취합하는 서버시스템으로 구축이 되었고, 인터넷과 3G망을 통해 각 농가의 자료를 취합한다. 수집된 생장환경 데이터는 최적의 작물 생장환경을 찾아내기 위해 다양한 방법으로 분석되고, 시각화되어 농가 컨설팅 자료로 활용된다.

Background and objective: This study was carried out to develop an effective technique for raising seedlings of Veronica pyrethrina Nakai, a native plant species in the Korean Peninsula, in plug trays. Methods: To investigate the optimum plug cell size and sowing media, we sowed seed in to plug trays with 34, 21, and 10 mL cells and filled with a commercial horticultural substrate and mixtures of peatmoss and perlite in 1:1, 3:1, and 4:1 ratios. Fertilization levels were set at 0, 500, 1000 and 2000 mg·L^-1. Results: Plug cell size did not significantly influence the seedling growth of V. pyrethrina. By substrate type, the growth rate was highest in the horticultural substrate, followed by 4:1, 3:1, and 1:1. Growth by fertilization level was higher in all fertilized treatment groups than in the control group, and there was no difference among 500, 1000, and 2000 mg·L^-1. Conclusion: The results of this study proved that it is most suitable for raising seedlings of V. pyrethrina to sow the seeds in a 10 mL cell plug tray filled with horticultural substrates, and apply fertilizers with less than 500 mg·L^-1 concentration.

Purpose: This study was done to identify degrees of factors influencing parenting self-efficacy in grandmother raising infant and toddler. Method: A convenience sample of 121 grandmothers whose grandchild was between 3 to 36 months old was used. The variables were health status, health problems and life event. The data were collected through a questionnaire survey and descriptive statistics, t-test, ANOVA with Scheffe test, Pearson correlation coefficients and stepwise multiple regression were used to analyze using SPSS WIN 12.0. Results: The average score for parenting self-efficacy was 39.39(SD=5.09), somewhat higher than moderate in level. Factor that was significant in influencing parenting self-efficacy was life event. This factors accounted for 14.6% of explained variance. Conclusions: It was found that the life event was influenced to parenting self-efficacy in grandmothers raising infant and toddler. From this study it is proposed that there is a need to develop programs and policies which support them. Ultimately a good care environment for children will be good for the young children's growth and development.

To improve trunk stability, various exercise protocols were introduced into the clinical field. Trunk and lumbar stability exercises on unstable surfaces are especially recommended to improve lumbar stability. The purpose of this study was to compare abdominal oblique muscle activity during leg raising in hook-lying position among 3 different type of surface conditions (on floor (F), vestibular board (VB), and foam roll (FR)). Sixteen able-bodied volunteers, who had no medical history of lower extremity or lumbar spine disease, were recruited for this study. Surface electromyography (EMG) activity was recorded from the internal and external oblique muscles of both sides. The normalized EMG activity was compared using a one-way repeated ANOVA. The results showed that the EMG activities of the internal oblique and external oblique of the lifted leg side during straight leg raising significantly increased under the FR condition when compared to the F condition. There was no significant difference of the EMG activity in abdominal oblique muscles between the VB and the FR conditions. The EMG activity of the internal oblique of supported leg side during the straight leg raising was significantly greater under the FR condition than the VB and F conditions (p<.05). The composition ratio of EMG activity of internal oblique muscles during straight leg raising was significantly increased under the FR condition. Therefore, straight leg raising exercise on foam roll in hook lying position could be beneficial to improve trunk and lumbar stability.

This study examined the working site environment of Korean native cattle raising farmers and their actual condition of wearing personal protective equipment as part of preventing disasters during agricultural work. To this end, 160 Korean cattle raising farmers were surveyed and a site visit was performed on 10 farms. According to an examination of the cattle breeding environment, the major harmful factors were in the following order: fine dust (12.8%), organic feed dust (10.3%), contact with cattle (9.7%), manure (8.2%), germs and viruses (8.1%), harmful gases (7.4), contact with obstacles (6.7), and temperature (6.6%). The current status of the rate of wearing protection was in the order of gloves (20.9%), working hats (19.7%), boots (19.6%), masks (10.9%), protective clothing (8.9%), and specialized working clothing (6.6%). Nevertheless, most Korean cattle raising farmers recognized the risks when they did not wear protective equipment and the need for wearing protectors, but they mostly did not wear personal protective equipment due to a lack of knowledge on the selection of appropriate personal protective equipment and the discomfort they experience when they put on protectors. Even when they put on protective equipment, 38% was inappropriate for the farming work environment. Given the research results, improvements on and the development of specialized working clothing and personal protective equipment to protect farmers from harmful and dangerous materials from the cattle nurturing environment is necessary. Overall, based on the study data, objectified data collection, a determination of the necessary performance elements of personal protective equipment, and R&D will be needed through an on-site current status investigation.

범죄 예방을 위한 환경 재설계 연구자들은 생활환경 가운데 야간에 어두운 공간에 대하여 조명을 설치함으로써 공간의 조도를 높이는 것이 범죄 예방 효과를 높일 것으로 보편적인 인식을 하고 있다. 단순하게 공간의 조도만 높이는 것이 모든 범죄 발생을 억제할 것이라고 보는 것은 실제 상황과는 맞지 않다. 본 연구에서 실제 범죄사건 사례를 분석한 결과, 생활공간에 조명을 설치하여 조도를 높이는 조치가 오히려 범죄를 실행하는데 활용되는 것이 분석되었다. 단순히 조명을 설치하고 조도를 높이는 것만으로 범죄를 억제할 것으로 보는 관점을 수정할 필요가 있다. 성범죄는 조도가 높아진 공간을 범행 대상을 관찰하는데 이용하는 경우가 많다. 따라서 단순하게 조도만 높이는 것 외에 보다 지능화된 상황인식 기능을 갖출 필요가 있는 것이다.

High mortality and slow growth of seedling generally occurred in tray due to cold, foggy weather and severe seedling blight. Mechanical transplanting is hampered, farmers having economic loss. A sustainable method for raising mat type seedling is necessary. Experiments were conducted on disease control and seedling growth in dry seasons. Fungicides treated/untreated seeds were sown 120-130g in each tray containing pulverized fine grain loam/sandy loam soils. Seed covered with a thin layer of soil and irrigated. It was polythene covered (PC) for 72h and then every night along with 2/3 sprinkler irrigation (SI) per day. Untreated seedlings infected 53-93%. Pyraclostrobin, Azoxystrobin and Azoxystrobin+Difeconazole treated seeds/sprayed (72h) seedlings had no disease. Seedling height was 11.7-13.2 cm with compact and thick root mat at 25 days. Seeds treated at 0.2-0.3% (18-20h) showed no disease but severely in untreated seeds in all locations. Seedling height (13.8 cm), leaf age (3.7) and root number (8.5) were better when NPK were applied at 3-4-3 g/tray. Spraying of urea (1%) in addition with MOP, theovit and $ZnSo_4$ at 0.6-0.6-0.2% on 7 and $15^{th}$ days was also effective. PC showed significant growth (29.1-34.5%). Root mat was not good in flooded irrigation (FI). Disease was higher in SI (66.7-97.3%) than FI (0.7-3.7%) in untreated seeds regardless of polythene use. The protocol would be effective for raising mat type seedling in cold environment.
