A study was carried out to investigate the dietary environment food intake and blood picture of rural housewives. Sixty percent of female farmer's was in weak health state. Mean farmer's syndrome score was 4, 7 which meaning that they must give attention to their health. The intake of animal food group was poor Most of nutrients taken by them were almost lower than those of Korean Recommended Dietary Allowances except vitamin C. According to the blood tests the blood levels of lipids calcium magnesium iron hemoglobin and hematocrit were in lower states. All of the farmers were lower serum level of ferritin whereas but glucose protein and albumin levels were normal. Serum magnesium was correlated with cereal intake The intake of cereal fat and oils and vegetables was correlated with physical perfect index. Hemoglobin and hematocrit level were negatively correlated with physical perfect index. Hemoglobin and hematocrit level were negatively correlated with the food group of fruits and fishes.

Based on the stress process model, this study examined the process of how military personnel's occupational characteristics (i.e., long and unspecified work hours, frequent moving) is associated with their wives' marital satisfaction and parenting stress. We focused on whether the wives' perception toward the characteristics of military occupation and the wives' military family pride mediated the association. An online survey was conducted with 323 women married to professional active-duty military husbands, had at least one preschool child, and lived with the husband and child. Using structural equation modeling, we found that the wives' perception of military occupational characteristics and military family pride mediated the relationship between their husband's work hours and the wives' marital satisfaction and parenting stress. This serial multiple mediation indicated that the longer and more unspecified the husband's work hours were, the more negative the wife's perceptions were towards his military occupation, which led to lower marital satisfaction and higher parenting stress. The single mediation effect of negative perceptions was also significant. Frequent moving was indirectly related to the wives' marital satisfaction and parenting stress through only the wives' negative perceptions toward military occupational characteristics. This result indicates that military spouses who experienced frequent moves are likely to have more negative attitudes toward military occupation, which leads to lower marital satisfactions and higher parenting stress. This study contributes to the literature by identifying the underlying mechanisms between military occupational characteristics and military wives' family life through the mediating roles of negative perceptions and military family pride.

식품산업 및 가정의 주방에 이르기까지 다양한 분야에서 식품을 가공 조리하는 곳에는 보건 건강을 위하여 비닐장갑은 반드시 필요하다. 최근에는 다양한 소재를 이용하여 위생 비닐장갑을 개발을 하고 있으나 일회용성으로 저가의 물품으로 인식되어 생활에 중요성에 비해 개발이 미흡한 실정이다. 위생 비닐장갑은 다양한 산업에서 필수품으로 활용되고 있는 만큼 위생적이고 내구성이 높은 제품의 개발이 절실히 요구되는 실정이다. 이에 본 연구에서는 봉합면의 측면이 사용중 터지지 않도록 하기 위하여 봉합선의 폭을 기존의 0.1 mm 대신에 1 mm정도로 넓게 하는 기술과 무균성 위생 비닐장갑의 제조 공정 자동화에 주력함으로써, 고품위 무균성 위생비닐장갑을 열공정 안정화 자동화 공정으로 제작코자 하였다. 본 연구의 수행시 당면한 가장 큰 문제점은 봉합선의 폭이 넓어짐에 따라서 knife 형태를 갖는 가열된 금형의 칼날이 비닐과 접촉되어 실링을 하는 단계에서 금형에 비닐이 녹아서 붙어버리는 sticking 현상이 발생하였다. 이는 현장에서 심각한 문제로 더 이상 상용화가 불가능함을 의미한다. 이에 본 연구에서는 금형(die) 재료로 2가지의 서로 다른 소재를 선택해서 상온 상압플라즈마 처리를 함으로써 금형과 비닐사이에 발생하던 sticking 문제를 해결하고자 하였다. 금형으로 사용한 소재는 스테인리스(STS304)와 공구강(SCM)을 사용하였다. 두 시편에 대하여 상온상압 플라즈마 처리를 수행한 뒤 증류수와 Diiodomethane를 이용하여 접촉각과 표면에너지를 측정하였다. 상온 상압플라즈마 처리 시간은 0 ~ 9초로 하였다. 스테인리스의 경우 접촉각이 증류수를 이용하였을 때 $69.7^{\circ}$, $32.2^{\circ}$, $16.7^{\circ}$였으며 Diiodomethane을 이용하였을 때는 $37.3^{\circ}$, $17.6^{\circ}$, $10.6^{\circ}$였다. 표면에너지(surface energy)의 경우 48.13 mN/m, 72.06 mN/m, 78.66 mN/m로 플라즈마 처리시간이 길어질수록 표면 에너지 값이 증가하였다. 공구강의 경우는 증류수를 이용하였을 때 접촉각이 $70.2^{\circ}$, $36.8^{\circ}$, $28.9^{\circ}$였으며 Diiodomethane를 이용하였을 때는 $38.65^{\circ}$, $22.8^{\circ}$, $20.2^{\circ}$였다. 표면에너지의 경우 47.43 mN/m, 69 mN/m, 73.15 mN/m로 스테인리스와 같이 표면에너지 값이 커지는 것을 확인할 수 있었다. 학술대회에서는 금형의 표면에너지를 증기시키거나 감소시키는 방법에 대한 연구결과를 발표할 예정이다.

This study investigated the correlation between eating behavior patterns, including eating-habits, food preferences, snack intake levels, and eating-out frequency and stress levels in high school students (males 174 and females 122) in Seoul. Analysis of eating-habits showed that eating-irregularity and eating-speed increased with elevated stress levels in both males and females under stress. The size of meals decreased in males, whereas it increased in females under getting stress (P<0.01). Preferences for sugar, hamburgers, and pizza also increased in both males and females under stress. Eating-out frequency decreased in males with a high stress level (P<0.01), whereas it increased in females. As for eating-out partners, males did not show any changes, whereas females preferred friends to family when under stress. Eating-out expenses also increased in both males and females, particularly in females with a high stress level (P<0.05). Males under increased stress showed effective stress reduction by increasing food intake, whereas females under increased stress showed less effective results. Consequently, high school students under high stress, particularly females, showed negative changes in eating behavior patterns, including irregular eating-habits, increased instant food and snack intakes, and increased frequency of eating-out. Therefore, development of appropriate programs for reducing stress and persistent nutrition education to promote good dietary behaviors are required.

개발도상국의 급격한 인구 증가에 의해 세계 60억 이라는 인구도 2050년을 맞아 약 100억에 도달할 것이라고 일컬어진다. 이로 인한 장래의 식량 위기에 대비하여 벼, 밀, 옥수수 등의 증산, 품종 개발도 물론 필요하지만 선진국을 중심으로 시장성 높은 작물의 소비가 우선되어지는 상황에 맞추어 세계적으로 주식이 될 수 있는 새로운 곡류의 확보와 생산체제도 중요한 문제이다. 한편으로 생활의 향상에 따른 식물의 다양화와 건강지향의 관점으로 본 다 품목 소량형의 식생활을 하는 것이 식물성 allergy의 방지 측면으로서의 곡류 특히 잡곡류의 유효 이용이 부각되어진다. 이들 중 amarans, quinoa는 벼과 식물에 비교해서 광합성능이 좋은 C4식물로서 생장이 빠르고 동시에 비타민, 무기질, 지질이 풍부하고 구성 단백질 중에 필수 아미노산을 많이 함유하여 아미노산 등급도 높고 특히 영양 발란스도 우수하다. 또 cholesterol 저하작용, 식물섬유에 의한 대장암의 억제 작용 등이 잘 알려져 있다. 그리l고 quinoa에 대해서는 아메리카 항공우주국(NASA)에서 CELSS(Controlled Ecological Life Support System; 장기간 우주특무비행의 승선원을 위한 공기중의 이산화탄소를 제거하고 식량·산소·물을 만들어 내기 위해 식물을 이용하는 방법)에 적합한 작물 후보로써 선택되어 신규 식품소재로써 주목받고 있다. 이상과 같은 견지로부터 amarans, quinoa를 일상식화되고 있는 빵에 이용하기 위해 제빵성 및 혼합중의 반죽의 모든 성질에 대해서 검토했다. amarans는 초과의 Amaranthus에 속하고 주요 생산국은 아메리카, 멕시코, 페루등이지만 일본에서는 주로 A.hypochondriacus가 수입되어 이용 되어지고 있다.amarans의 가루는 단독으로는 점탄성 있는 반죽을 형성하지 않기 때문에 밀가루에 일부를 대용한 wheat flour dough를 사용하고 가정용 제빵기로 구워 최종 단계에까지의 제빵성 결과를 산출했다. amarans folur 5%의 대체에는 빵의 비용적이 비교적 증대했지만 그 이상 amarans flour을 대처하면 확연히 비용적은 감소했다. amarans flour 10% 대체에 hemicellulase 1250U 이상을 첨가하면 비용적은 눈에 띄게 증대했다. farinograph에 있어서 반죽의 안정성은 amarans flour 10% 대용에 현저히 감소했다. 반죽의 점탄성(아축응력, 탄성률, 점성계수)는 amarans flour 10%를 대용한 것이 무첨가한 것보다 많이 단단해졌음을 알 수 있었다. 혼합중의 반죽의 조사형 전자현미경 관찰로 amarans flour로 대체한 gluten이 단단해졌음을 알수 있었다. 유화제 stearly 칼슘, 혹은 hemicellulase를 amarans 10% 대체한 밀가루에 첨가하면 확연히 비용적을 증대시킬 수 있다는 사실을 알 수 있었다. quinoa는 명아주과 Chenopodium에 속하고 페루, 볼리비아 등의 고산지에서 재배 되어지는 것을 시료로 사용하였다. quinoa 분말은 중량의 5-20%을 quinoa를 대체하고 더욱이 분말중량에 대하여 0-200ppm의 lipase를 lipid(밀가루의 2-3배)에 대하여 품질개량제로서 이용했다. 그 결과 quinoa 대량 7.5%에서 비용적, gas cell이 가장 긍정적 결과를 산출했고 반죽의 조직구조가 강화되었다. 또 quinoa 대체에 의해 전분-지질 복합제의 흡열량이 증대된 것으로부터 전분-지질복합제의 형성 촉진이 시사되었다.이것으로 인하여 호화억제에 의한 노화 방지효과가 기대되었지만 실제로 빵의 노화는 현저히 진행되었다. 이것은 quinua 대체량 증가에 따른 반죽의 안정성이 저하되어 버린 것으로 생각되어진다. 더욱이 lipase를 첨가하면 반죽이 분화하는 경향이 보여졌지만 첨가량 75ppm에 있어서 상당히 비용적의 증대가 보였다. 이것은 lipase의 가수분해에 의해 생긴 monogliceride에 의한 유화각 일어나서 보존성이 개선되어진 것으로 quinoa를 보다 많이 빨에 이용하기 위해서는 lipaserk 품질개량제로서 유효하다는 것을 알 수 있었다. 또 lipase는 quinoa의 대체량이 비교적 많은 10-20%의 섭취가 곧 allergy 질환 문제의 개선책이 되는 것은 물론 amarans, quinoa에는 lysine, 함황아미노산이 많고 지질중의 지방산조성도 좋고 무기질도 많이 함유되어 있다. 이와같이 우리들 개인의 건강에 대한 배려도 있고 amarans, quinoa등의 식품재료를 적극적으로 사용할 수 있도록 유념해 두었으면 하는 바램이다.

The purpose of this study was to analyze the curriculum competencies of relationship-forming ability and practical problem-solving ability reflected in the activity tasks corresponding to the content elements of 'Love and marriage', 'Preparation for parenthood', 'Pregnancy and childbirth', 'Child care', and 'Family culture and intergenerational relationship' in the 2015 revised high school technology & home economics textbooks. The data are 330 activity tasks from 12 kinds of high school technology & home economics textbooks. The sub-factors of the relationship-forming ability were selected as Respect for Diversity, Consideration and Care, Family Relationship and Community Spirit, Empathy Ability, Conflict Management, and Communication, and the sub-factors of practical problem-solving ability were selected as Practical Reasoning, Decision Making, Value Judgment, Critical Thinking, and Executive Power. Based on the analysis criteria, the results of the two analyses and the expert review are as follows. First, regarding both the core concepts 'Development' and 'Relationship', the share of relationship-forming ability was relatively higher than practical problem-solving ability, and conflict management and executive power were the least reflected. For the core concept 'Development', Family Relationship and Community Spirit and Critical Thinking were the most reflected sub-factors, and for the core concept 'Relationship', Consideration and Care and critical thinking were the most reflected sub-factors. Second, in the case of the relationship-forming ability, the examples of activity tasks across sub-factors of each subject competency were devised to understand diverse opinions and sentiments and to develop competencies to care for each other and maintain healthy family relationships. In the case of practical problem-solving ability, the tasks allowed students to objectively analyze the socio-cultural background underlying the real-life problem, explore alternatives, and apply in their own lives.

The aim of this study is to predict use behavior for social welfare service of the elderly mentally ill through means-end chain theory. Means-end chain theory explains cognitive structure related to the consumer's preference to various products and services. Although the elderly mentally ill begin to emerge as new client population, social welfare services for them do not seem to be enough in the community. Based on this awareness, this study tried to analyse service use behavior of the elderly mentally ill through means-end chain theory to develop new social welfare services. The data were collected from 15 elderly mentally ill and found 5 attributes, 10 consequences, and 11 values. Hierarchical Value Map was composed of 'disease management, rehabilitation preparation, hobby leisure ${\rightarrow}$ health maintenance, energy of life ${\rightarrow}$ social reintegration, life satisfaction, harmonious family life'. To activate the social service for the elderly mentally ill, it should be developed various programs such as disease management, rehabilitation preparation, hobby leisure for the elderly mentally ill. The ultimate value of these programs will be improve life satisfaction and integrated into society.

This study was conducted in order to attain an in-depth understanding of and describe the Ego-Integrity Phenomenon of the elderly of age 65 and older. The data was collected from June 2020 to July 2020 as an in-depth interview consisting of semi-structured questions. The data was analyzed using the Colaizzi's method, one of the phenomenology methods. All interviews were recorded and transcribed for analysis. Through analysis, 309 significant statements were extracted, and 88 formulations of meaning, 53 themes, 16 theme clusters, and 5 categories were derived. The categories and the theme clusters are as such : 'reflecting on the past life with delight' ('fruitfulness over the lifetime', 'achieving through fulfilling responsibilities', 'achieved specially and gratefully'), 'Currently lonely and distressed due to the bitter old days' ('Physical health needs and psychosocial needs are not met', 'Wasn't able to make good choices for parents and children', 'Elderly life is not easy'), 'Satisfaction from enduring tough and difficult journeys in life' ('Compensated for hard work at workplace and home', 'Problem solved through endurance and overcoming', 'Living a healthy elderly life by escaping from the habits of the past'), 'Realizing the way of life as an elderly' ('Now is the best and most satisfying moment', 'Managing self in old age', 'Living passionately, though it may be late', 'Retiring from the forefront of life with an abundant heart'), 'Passing on beautifully' ('Desires toward the later years', 'Hope during the last moments', 'Appearance and emotions when death approaches'). It was observed that during the Ego-Integrity Phenomenon of the elderly, they have come to discern the meaning of life by reminiscing the regrets and difficulties of the past, and through this reminiscence, they have come to attain a positive and transcendental hope for the rest of their lives. The Ego-Integrity of the elderly appeared to be subjective, dynamic, and occurring simultaneously rather than continuously. It is recommended to develop a variety of nursing interventions while taking into consideration the age and the type of experience of the elderly.

The purpose of this study is to analyze factors relationship between dental caries experience and obesity among elementary school of student's in oral health clinic to provide empirical data for school of oral health program. The subjects of this study consists of 235 elementary school student's in Gyeongsan area. The data were collected from July 1 to 30, 2011 by self-administrative questionnaires. Increased with age in the lower level dental caries experience. Dental caries experience and obesity realted to were not with Mother's employment status, education level, economic level each other. Number of weekly exercise normal weight (9.4%) than obesity weight (21.5%) was higher in the 0 times. The obesity and dental caries experience was not associated with each other. The results suggest that social and demographic variation and regardless of don't home care made in support do student's oral and health care school health in terms of how much management so school oral health clinics later gradually enlarge and systematic a national policy will be implemented.
