Aim of this study was to investigate whether middle school students with different body mass index (BMI) and sex were different in their lifestyles and nutrient intake. Middle school students (n=408) in Gyenggi-do were participated in this stsudy. Height, weight and BMI of female students were 159.6㎝, 50.4㎏, and 19.7 ㎏/㎡, and those of male students were 165.5㎝, 57.7㎏ and 20.9㎏/㎡, respectively. Classified by BMI, there were 30% underweight, 51% normal, and 18.9% overweight. Reading time of underweight group was significantly shorter than those of overweight. More underweight students thought themselves healthier and had more appetite than overweight subjects. Male students used computer significantly longer and ate more on time, but had more unbalanced diet than females. Male students consumed more calorie, protein, vegetable protein, vegetable fat, carbohydrate, sodium, vitamin B1. Intakes of fiber and calcium were lower than the Dietary Reference Intakes for Koreans for that age group. Our results suggested that students had meal not on time, unbalanced diet, and meal too fast. Intakes of protein, fat, and sodium were higher, but intakes of calcium and fiber were too low. Those may cause serious health problem. Thus, students and health care providers should recognize the problems and develop education programs to help students to keep proper life style and eating habits.

자아초월 정신의학이 체계화되면서 영성(spirituality)은 인성의 한 부분이라는 이론이 대두되었는데 이 영성은 정신건강에 큰 영향을 미친다고 했다. 인간의 성향 중 영적 안녕 정도를 파악하여 그 정도가 정신건강 중 허위성 경향, 정신병적 경향 및 불안과 우울 경향 등에 어떠한 영향을 미치는지를 조사하고저 본 연구를 실시하였다. 대상은 중국의 연변 조선족 자치구에 거주하는 여성 400명을 대상으로 하여 한국판 영적 안녕척도를 사용하여 영적 안녕정도를 파악하였다. 영적 안녕척도의 총점과 이 척도의 2개 하위 척도인 종교적 안녕과 실존적 안녕 척도 양자로 평가한 성적이 불안-우울통합척도와 정신분열증 척도 및 허위성 척도로 평가한 성적에 미치는 영향을 검증하기 위하여 상관관계분석 및 회기분석을 실시하였다. 그 결과는 다음과 같다. 1) 영적 안녕척도로 평가한 조선족 여성의 총점은 68.29로 한국의 기독교 여성이 평가한 100.65보다 훨씬 낮은 점수였다. 2) 불안·우울통합척도로 평가한 총점은 44.88로 연변노인이 평가한 점수와 일개지역의 한국농촌주민이 평가한 점수와 비슷한 결과였다. 3) 허위성 척도로 평가한 성적은 평균 74.57로 70점 이상이 86%(344명)이었으나 영적 안녕 성적과 허위성 성적 간에는 유의한 상관이 없었다. 4) 영적 안녕총점은 정신분열증 척도로 평가한 정신병적 경향에 유의한 영향을 미치지 않았으나 종교적 안녕하위척도의 성적은 정신병적 경향을 높여준데 비하여 실존적 안녕하위척도의 성적은 정신병적 경향을 낮게 해주었다. 5) 영적 안녕척도의 총점 및 두 하위척도인종교적 안녕과 실존적 안녕은 불안과 우울에유의한 상관을 보였는데 영적 안녕총점이 높을수록 불안·우울 총점이 다소 낮아지는 경향을 보였다. 6) 종교적 안녕 하위척도와 불안과 우울과의 관계는 종교적 안녕점수가 높을수록 불안과 우울을 각각 다소 유의하게 높여주었으며 이에 비하여 실존적 안녕하위척도와 불안과 우울과의 관계는 실존적 안녕정도가 높을수록 불안 및 우울점수는 유의하게 낮아졌다. 이와 같은 성적을 미루어볼 때 연변에 거주하는 조선족 여성이 평가한 영적 안녕정도는 정신병적 경향과 불안 및 우울에 유의한 상관을 보였으면 이 척도의 하위 척도인 종교적 안녕정도는 정신건강에 부정적인 영향을 미치는 반면 실존적 안녕정도는 정신건강에 긍정적 영향을 미친 결과로 평가되었다. 이러한 결과는 공산주의 사회에서 실존적 안녕은 긍정적인 가치관으로 평가되는 반면 종교적 안녕은 정신건강에 부정적으로 작용한 것을 입증해 주었다고 하겠다. Background: Spirituality has been an important part of Transpersonal Psychology and is believed to have a large effect on the mental health because it has been systematized. The aim of this study was to determine the level of spiritual disposition on human beings along with its effects on one's mental health. Materials and Methods: The study targeted 400 women residing in Youn-Gil city of JiLin Prov., which is a district of the Cho-Sun tribe in China. Their spiritual well-being was studied using the Spiritual Well-being Scale-Korean Version. The spiritual well-being scale consists of 2 sub-scales of religious well-being and existential well-being. The study was evaluated using a lie scale, psychotic trend, and a combined anxiety-depression scale. The results were considered to be factors of one's mental health. The correlation between the spiritual well-being and each tendency was analyzed by regression analysis. Results: The total score of the Cho-Sun tribal women according to the spiritual well-being scale was 68.29 which was much less than the 100.65 of Korean Christian women. There was no significant correlation between the spiritual well-being and the Lie trend. However, it was found that 86%(344) of Cho-Sun tribal women scored above 70 in the Lie trend with a mean score of 74.57 which is higher than normal populations. Regarding the correlation between the spiritual well-being and psychotic trend, the psychotic trend became significantly higher when the religious well-being was at a high level. On the other hand, the psychotic trend became significantly lower when the existential well-being was at a high level. Regarding the correlation between the spiritual well-being and anxiety, the anxiety was significantly higher when the religious well-being was at a high level. However, the anxiety level was significantly low when the existential well-being was at a high level. Regarding the correlation between the spiritual well-being and depression, the depression level was somewhat significantly high when the religious well-being was at a high level. However, the depression level was significantly low when the existential well-being was at a high level. Conclusion: This study evaluated the effects of spiritual well-being on a person's mental health among Cho-Sun tribal women in Youn-Gil city of JiLIn Prov., P.R. of China. The results found that the religious well-being, which is a sub-scale of spiritual well-being, had negative effects while the existential well-being had positive effects on the mental health. These results proved that a person's religious disposition had negative effects on their mental health in a communitarian society.

Hyoung Jin Kim,Sun Young Koo,Bong-Hyun Ahn,Oeuk Park,Doo Hoe Park,Dong Ook Seo,Jong Heon Won,Hyeon Joo Yim,Hyo-Shin Kwak,Heui Sul Park,정철웅,Young Leem Oh,Soon Ha Kim 대한약학회 2010 Archives of Pharmacal Research Vol.33 No.11

Mitochondrial reactive oxygen species and reactive nitrogen species are proven to be major sources of oxidative stress in the cell; they play a prominent role in a wide range of human disorders resulting from nonapoptotic cell death. The aim of this study is to examine the cytoprotective effect of the NecroX series against harmful stresses, including pro-oxidant (tertiarybutylhydroperoxide), doxorubicin, CCl4, and hypoxic injury. In this study, these novel chemical molecules inhibited caspase-independent cell death with necrotic morphology, which is distinctly different from apoptosis, autophagy, and necroptosis. In addition, they displayed strong mitochondrial reactive oxygen species and ONOO− scavenging activity. Further, oral administration of these molecules in C57BL/6 mice attenuated streptozotocin-induced pancreatic islet β-cell destruction as well as CCl4-induced hepatotoxicity in vivo. Taken together, these results demonstrate that the NecroX series are involved in the blockade of nonapoptotic cell death against mitochondrial oxidative stresses. Thus, these chemical molecules are potential therapeutic agents in mitochondria-related human diseases involving necrotic tissue injury.
