  • Today, the role of kindergarten is more important as nutrition provider through snack and meal services. Desirable kinds and amounts of food items at school lunch menu were important factors of nutrients intakes in children. This study was performed to assess the kindergarten's meal service program (snack and lunch) and the consumption amount of lunch according to each dishes. Twenty four institutions that cared over one hundred children were observed at Seoul and Kyunggido area. Well-trained observers checked meal and snack serving activity and foodservice facilities by formal checklist. And using the weighing method assessed the consumption levels of food items at lunch. During 3 days, 30 children in each kindergarten were selected randomly according to age, observers measured serving and residual weight of each food. The data was compiles by performing ANOVA-test using SPSS WIN 10.0. The result were as follows: 1) Foodservice facilities in kindergarten was limited to provide qualified foodservice. $91.7\%$ of institution had kitchen, $41.7\%$ had dinning. The kitchen equipment possession rate was $12.5\%$ (oven), $30.8\%$ (heating cabinet), $58.3\%$ (refrigerator). The rate of using document about foodservice was used $83.3\%$ (menu list), $41.7\%$ (daily foodservice record), $25\%$ (standard recipe). $41.7\%$ of institution employed licensed dietitian. Only $41.7\%$ of subjects preserved meal after daily meal service. 2) Meal serving size was decided by teacher, $54.5\%$ at snack and $43\%$ at lunch and pre-divided individual portion type was $36.4\%$ at snack and $28.6\%$ at lunch. The rate of cleaning activity before meal was $72.2\%$ at snack, $90.5\%$ at lunch. And nutrition or sanitation education activity was more performed at lunch time, for examples brushing teeth activity was $12.5\%$ at snack $85.7\%$ at lunch. 3) The consumption amounts of plain cooked rice was $112.7{\pm}26.1{\cal}g$, cooked rice and cereal was $93.06{\pm}27.97{\cal}g$, curry rice was $208.35{\pm}64.84{\cal}g$ and the consumption amounts of these main dishes was significantly different by age (p < 0.001). The consumption amounts of soup was very different according to children's preference. The consumption amounts of seaweed soup was $120.18{\pm}82.13{\cal}g$, wild sesame and bean-paste soup was $40.64{\pm}23.16{\cal}g$. The consumption range of kimchis was from $6{\cal}g\;to\;13{\cal}g$, jorim (braised food) was from $3{\cal}g\;to\;25{\cal}g$, fried food (include stir fried, deep fat fried, pan fried) was from $14.5{\cal}g\;to\;22{\cal}g$, vegetable dish was from $3{\cal}g\;to\;16{\cal}g$. These consumption amount of each dishes was not reached recommended portion size of nutritionally planning menu by nutritionist.

  • 3D CAD 시스템으로 설계된 해양플랜트 배관재 모델들은 2D 배관 제작도와 설치도의 형태로 생산 공정에 제공되고, 기본 엔지니어링 정보와 함께 통합 공정관리시스템에서 원자재의 구매, 조달, 제작, 설치 및 검사가 체계적으로 관리되어 진행된다. 기존의 통합 공정관리시스템은 자원의 흐름 및 진행 상황을 체계적으로 관리하여 공정 시수 절감에 많은 기여를 하고 있지만, 3D 설계 형상 모델 정보를 포함하고 있지 않기 때문에 배관 설치 작업 전에 복잡한 배관 구조를 파악하거나, 잦은 설계 변경으로 인해 연관된 도면을 찾을 때 상호간 신속한 정보 교류가 어려운 단점을 가지고 있었다. 이러한 문제점을 해결하기 위해 3D 모델을 기반으로 하는 해양플랜트 배관 공정 모니터링 시스템을 개발하였다. 본 시스템은 3D 모델 기반 배관 모니터링 시스템은 Visual Studio 2017 C#과 UNITY3D를 기반으로 배관 공정 작업 정보가 3D CAD 모델과 실시간 연동될 수 있도록 구성하였다. 그리고 블록, 크기, 재료에 따른 배관 설치 공정 진행 흐름 뿐만 아니라, 청소, 수압검사, 공압검사 등 기능 검사 항목별 진행 흐름을 3D 모델상에서 실시간으로 확인할 수 있도록 하였다. 작업자는 개발된 시스템을 통해 생산 현장에서 실시간으로 배관 공정 진행 흐름을 포함한 3D CAD 모델을 쉽게 파악함으로써 작업 효율성 향상에 많은 기여를 할 것으로 기대된다.

  • Ostomates have suffered from many difficulties due to their physical, psychosocial handicaps and changes of life style to include ostoma management that influences their daily and quality of life. An appropriate nursing education for ostoma management is very important. Practical educational materials needs revision because those were developed by pharmaceutical companies and hospital institutions. The purpose of this study is to provide more practical and reasonable education materials for ostomates by doing analysis and survey of educational materials now being used. We surveyed 8 types of educational materials used in 23 university hospitals and medical centers in Seoul ; four of them were developed by department of nursing and the remainder by an Ostomy Company Data, collected from July 14, 1997 through July 31, 1997 were analyzed. The results are as follows ; 1. The analysis of education guide, on ostomate included 14 subcategories : introduction, structure and function of gastrointestinal tracts, definition of stoma, types of ostomy, definition of peristalsis, methods of defecation management, selection of instrument, resolution of problems and general situations following surgery, daily life, where to ask for help, explanations for terms, information about where to buy instrument, explanations for enterostomal therapist, a matter of consultation with doctor, etc. 2. Introduction contained specific contents on practical ostomate management that ostomates would experience through their lives. Ostomate education guides were developed 3 hospitals except one which missed this point. 3. Most ostomate education guides, except one hospital, helped ostomates to understand their physical structure changes with specific explanations on gastrointestinal tracts with figures. 4. Six institutions did not talk about the definition of peristalsis. 5. All institutions, except two, helped ostomates to understand types of ostomy with figures. 6. More detailed explanations on natural defecation are needed. The benefits and pitfalls of natural defecation should be more specified. 7 No psychosocial difficulties of ostomy management were addressed. 8. The efficiency of enema can be better understood through all explanations with figures. Some institutions did not mention items about definition, benefits, pitfalls of enema, sequency of enema, how to wash, cautions performing and enema, skin management, cleaning instrument after enema proper time to spend. 9. There were no detailed contents and what to do in case of not being able to do enema. 10. Only one educational material mentioned emotional aspects after the surgrey. 11. Most institutions explained subcategory of daily life but did not provide specific contents on the difficulties of physical, psychological, and sociocultural controls. 12. The subcategory of ureterostomy education guides included explanations on normal structure and function of urinary tracts, types of ureterostomy, how to manage skin, usage and types of instrument, commercial urostomy, how to manage instrument, daily life, introduced the general contents. However, more specific explanations were needed.

  • These days social and economical changes have influence on the structure of family and the role of family members. Working mothers and widowers with children are increasing because of economical difficulties. Support from relatives are decreasing because of the conspicuous trend toward nuclear families. According to these reasons androgynous fathers are required. Today's fathers in Korea socially and culturally have learned about traditional parenting, but they are changing their fathering styles to meet the demands of the times. However they don't have their own fathering models. Therefore nurses who hold an advantageous position to teach and support from clinic have to encourage them to care their infants. The purposes of this study were to define father's care giving in infancy, understand influencing factors on fathering, and the differences between fathering and mothering, then contribute to nursing implementation for supporting fathers. This study was designed to review references about father's care giving. The results were follows: Six aspects of parent participation were direct care. indirect care, play, decision-making concerning the child, amount of time of sole responsibility for the child and overall availability to the child. Direct care involved feeding, bathing, going to child if child awakens. dressing, putting child to bed, taking child to doctor, nurse, or dentist, transporting child to and from sitter, day care, or school, washing child's hair. Indirect care involved cleaning up after child, preparing child's food, fixing child's broken playthings, washing child's clothes, arranging baby-sitting, shopping for child's toys and clothes, transporting baby-sitter to and from your home. Young fathers were gradually participating in direct care like feeding, taking child to doctor. Father's care giving stimulated mothering and promoted parent-infant relationship. Influencing factors of fathering would be divided into father characteristics, surrounding factors, infant attributes. Father characteristics were age, role perception, relationship with parent. Surrounding factors were the opportunity of early contact, support system, spouse's expectation, marital adjustment, feeding type, past experience of care giving. Infant attributes were temperament, behavior, age, sex. The differences between fathering and mothering were reviewed. Fathers were poor at care giving. but their caring was similar to mother's. This subtle difference positively worked upon infant's growth and development. On the basis of these theoretical data, nurses can empower fathers to cooperate with mothers in caring infants.

  • 본 연구는 만화영화 <월-이(Wall-E)>의 의미를 분석하여 유아교육에 대한 시사점을 도출하고자 하였다. 분석방법은 Wolcott(1994)의 개념에 근거한 질적 자료 분석 방법 중 해석적 분석 모형을 사용하여 다음과 같은 연구결과를 도출하였다. 첫째, 지구는 오염되고 파괴되어 버려진 땅으로 나온다. 액시엄은 지구를 파괴한 주체인 나태한 사람들의 안식처로, 선장실은 각성과 변화의 실마리를 얻는 공간이 된다. 둘째, 시간이 지남에 따라 액시엄은 귀환도구로 역할을 하며, 지구는 고향, 터전으로 인식되어 인간이 돌아왔을 때는 희망의 땅이 된다. 셋째, 캐릭터 중 <월-이>는 변화의 주체가 되어 자신뿐 아니라 인간들까지도 변화시킨다. 인간의 욕심은 지구에서의 생태적인 삶을 파괴하였다. 그러나 사람들과 서로 관계 맺고, 지구를 살리는 노력을 한다면 인류를 지속가능한 발전으로 이끌 수 있다. 본 영화를 분석한 결과 생태적 미디어가 가지는 특성인 자연친화 및 예찬, 자연파괴 및 현대문명 비판, 생명의 존엄성, 생태의식 함양, 공존, 공생, 상생의 원리 등의 요소들을 발견할 수 있었고, 유아들의 생명에 대한 감수성을 기르는 데 도움이 될 것으로 기대한다.

  • Purpose: This study was done to investigate the status of disinfection and sterilization in healthcare facilities. Method: A survey of 193 Korean healthcare facilities was conducted from February 8 to March 7, 2013. Data were analyzed using descriptive statistics, ${\chi}^2$ test, Fisher's exact test, one-way ANOVA, Scheffe with SPSS WIN 18.0. Results: Of the healthcare facilities 93.2% had specific guidelines for disinfection/sterilization, but only 47.9% had a committee on disinfection/sterilization for decision-making, less than half (42.7%) conducted regular monitoring of actual practices, while 83.9% had established procedures for recovery in case of problems with the disinfection process and 89.0% kept records and archives of disinfection practices. Cleaning process, selection of chemical disinfectants and process of disinfection and sterilization were found to be inadequate in some healthcare facilities. Perception score for adequacy of medical instruments was 8.10, environmental disinfection was 7.20, and sterilizer management was 8.45 out of a possible 10. Conclusion: Compared to larger institutions, smaller healthcare facilities had less effective disinfection and sterilization management systems, while some facilities showed inadequate practices for medical equipment and general sterilization. Better academic and state-level support is recommended for smaller facilities in order to establish a better system-wide management system.

  • Background: Among women with haematuria, defining individuals under high risk for bladder cancer based on reproductive factors prior to cystoscopy would be of great benefit in the management of this condition. The aim of this study was to compare age and reproductive factors such as menopausal status, parity, age at first delivery and age at the last delivery between women who have haematuria with or without bladder cancer. Materials and Methods: A total of 463 patients underwent diagnostic cystoscopy in D$\ddot{u}$zce University Faculty of Medicine between 1 June 2008 and 1 June 2013. Female patients who presented with persistent microscopic or macroscopic haematuria and underwent standard evaluation for haematuria including urinalysis, urine culture, urine cytology, urinary tract imaging with excretory urography or computerized tomography with contrast enhancement and endoscopic evaluation of the urethra and bladder were included in this study. Exclusion criteria were tobacco use and high risk occupations for bladder cancer such as textile, dry cleaning, painting and etc. Forteen women had hematuria due to benign conditions, and 18 due to bladder cancer. Data were retrospectively retrieved from the medical records of Duzce University Hospital. Results: Patients with haematuria due to benign reasons did not significantly differ from patients who were found to have bladder cancer in terms of age (p=0.28), menopausal status (p=0.29), mean parity (p=0.38), being nulliparous (p=0.57), parity ${\geq}3$ (p=0.22), age ${\leq}18$ years at first delivery (p=1.00), age ${\geq}30$ years at last delivery (p=0.26), age ${\geq}35$ years at last delivery (p=0.23) and percentage of the patients with advanced age (${\geq}65$ years) (p=0.18). Conclusions: It is difficult to predict a high risk for developing bladder cancer in women with haematuria based solely on reproductive factors.
