This study investigated the relationship among the flight stress, disease and eating behavior of the Airline cabin crews. Self administered questionnaires were collected from three hundred and twenty cabin crews. Statistical data analysis was completed using a SPSS v.10.0 program. The results were summarized as follows: Before the flight, the maladaptation to the oversea foods was the most common stress for the crews less than one year flight experience. During the flight, fastidious arrangement and loss of appetite due to overwork were the most common stresses. After the flight, anorexia due to jet lag was the most common stress. Backache and stomachache were the most common job-related ailments of the airline cabin crews. During the flight, the intakes of carbonated drinks and coffee were most common. After the flight, water was the most common drink they consumed.

This study was conducted to evaluate nutrient intake, indices of anemia, serum lipids, and their correlations in 40 Korean female college students aged 21 to 25 years, Fasting blood samples were collected in October, 1997. Nutrient intake was investigated by 24-hour recall method for three days, Anthropometric measurements, blood pressure, iron status and serum lipids of the subjects were determined. The mean values for age, height, weight, BMI and blood pressure of the subjects were 22.1 years, 160,6cm, 54.4kg and 109.1/66.9mmHg, respectively. According to the body composition analysis, total body water, % body fat, lean body mass and WHR were 26.7L, 29.5%. 36.5㎏ and 0.8, respectively. Average daily intake of energy was 1,858.4kcal. Protein, phosphorus, vitamin B₁, vitamin B₂, niacin and vitamin C intakes were higher than the Korean recommended dietary allowence(RDA), whereas calcium, iron, vitamin A intakes were lower than that, Hemoglobin(Hb), hematocrit(Hct), serum iron(SI) and total iron binding capacity(TIBC) were measured and transferrin saturation(TS%) was calculated from serum. The mean values for Hb, Hct, SI, TIBC and TS were 13.6㎍/dl, 41.6%, 97.8㎍/dl, 319.6㎍/dl and 31.9%, respectively. The prevalence rates of iron deficiency assessed by Hb and Hct were found to be 10% and 2.5%, respectively. However, when assessed with TIBC, the prevalence rate of iron deficiency was increased to 32.5%. The mean values for serum triglyceride(TG), total cholesterol(TC), HDL-Chol, LDL-Chol concentrations and atherogenic index(AI) were 154.7mg/dl, 80.0mg/dl, 47.1mg/dl, 91,3mg/dl and 2.6, respectively. Correlations among indices of anemia, there were positive correlations between Hb and Hct, between SI and TS: negative correlations between TIBC and TS or SI. Correlations among serum lipids, there were positive correlations between TC and TG or LDL-cholesterol. Energy intakes were correlated positively with TIBC(p<0.05), and vitamin C intakes negatively correlated with Hb(p<0,05). And vitamin A intakes were negatively correlated with TG(p<0.01), TC(p<0.05) and LDL-Choi(p<0.01). Hb negatively correlated with TG(p<0.05). Body weights(p< 0.05), lean body mass(p<0.05) and total body water(p<0.01) werenegatively correlated with Hb. BMI and WHR correlated with TG and TC(p<0.01). These results indicated that subjects with higher energy intake and overweight had a tendency to have iron deficiency. Increases in BMI and WHR were related to increases in serum lipids levels and decreases in TIBC. The results also showed that serum lipids were decreased when vitamin A and iron intakes were sufficient.

The survey study was conducted to investigate the rice cake consumption pattern including the frequency of intake and the degree of preference and the area of improvement for Korean rice cake among college students. About the motive for purchases of rice cake, 'taste is good(43.3%)' was the highest, and 'eat as a snack' the next (42.9%). The reason which does not eat the rice cake frequently was uncomfortable to eat (24.1%), insipid(21.4%), not variously assorted(17.9%) in the order named. The college students surveyed were eating rice cake as a snack mainly. They wanted the rice cake to be charmed and be in pretty shape, and fusion style for gift. And they wanted to be rice cake more sweetened and cool taste like ice cream. Therefore, traditional rice cake is required for further research for the development of product which is more acceptable for the young adults.

박성균,이강숙,노영만,구정완,민선영,한진구,고원경,김미란,정재근,이종승,김진홍 大韓産業醫學會 2000 대한직업환경의학회지 Vol.12 No.1

목적 : 본 연구는 지방조직과 혈청의 PCBs와 DDE 농도를 측정하고, 이에 영향을 미치는 것으로 알려진 요인들과의 관련성을 평가하고자 하였다. 방법 : 유방암, 자궁내막증 등 유기염소계 화합물의 영향이 있는 것으로 알려진 호르몬 관련 질병을 제외한 부인과 환자 52명을 대상으로 지방조직과 혈청을 분석하였으며, 설문조사를 통하여 연령, 교육수준, 직업, 비만도, 흡연과 음주, 출산력, 수유력등을 조사하였다. 지방조직과 혈청의 PCBs와 DDE 농도는 가스크로마토그래피를 사용하여 측정하였다. 결과 : 지방조직의 경우, 13개 PCBs congeners 농도의 합은 중앙값이 48.29 ng/g, 기하평균값이 56.78 ng/g이었고, DDE 농도는 중앙값이 142.89ng/g, 기하평균값이 117.06 ng/g이었으며, 혈청의 경우는 PCBs congeners 농도의 합은 중앙값이 4.67 ㎍/L, 기하평균값이 4.85 ㎍/L이었고, DDE 농도는 중앙값이 1.75 ㎍/L, 기하평균값이 2.09 ㎍/L로 나타났다. 지방조직과 혈청의 DDE 농도 사이는 높은 상관성을 보였으나(r²=0.310, p=0,0002), PCBs는 상관성이 약한 것으로 나타났다(r²=0.029, p=0.2582). 영향요인을 범주화한 후 로그변환 시킨 지방조직과 혈청의 PCBs, DDE 평균의 차이를 분석한 결과, 지방조직의 DDE만이 출산자녀수(p=0.015), 초산연령 (p=0.014), 비만지수(p=0.035)와 연관성이 발견되었다 다중회귀분석의 결과 지방조직의 DDE는 출산자녀수가 적을수록, 초산연령이 늦을수록 증가하는 경향을 보였다. 결론 : 출산자녀수와 초산연령, 비만도가 지방조직의 DDE와 관련성을 보였으며, 또한 유기염소계 화합물의 장기간의 노출에 의한 영향을 평가하는데 있어서 혈청보다 지방조직이 더 유용한 생물지표임을 알 수 있었다. Objectives : This study was purposed to determine the levels of PCBs and DDE in adipose tissue and serum and to evaluate the relations with factors affecting these levels. Methods : We analyzed adipose tissues and sera from 52 gynecologic benign disease patients aged 27-78 years, except hormonal diseases such as breast cancer and endometriosis. We also surveyed age, education, occupation, body mass index (BMI), smoking, drinking, number of children, and duration of breastfeeding by questionnaires. Tissue and serum levels of PCBs and DDE were measured using gas chromatography. Results : The median and geometric mean levels of PCBs were 48.29 ng/g, 56.78 ng/g for adipose tissue and 4.67 ㎍/L, 4.85 ㎍/L for serum, and those of DDE were 142.89 ng/g, 117.06 ng/g for adipose tissue and 1.75 ㎍/L, 2.09 ㎍/L for serum, respectively. Adipose tissue and serum levels for DDE showed high correlation (r²=0.310, p=0.0002), but those of PCBs didn't (r²=0.029, p=0.2582). In analyses of the differences of the means of log transformed adipose tissue and serum PCBs and DDE levels for groups of potential covariates, only adipose tissue DDE levels were significantly associated with number of children (p=0.015), age at first birth (p=0.074) and BMI (p=0.035). In multiple regression analysis, adipose tissue DDE levels were significantly increased with decreasing number of children and increasing age at first birth. Conclusions : This study suggested that parity and adiposity were associated with levels of DDE in adipose tissue, and adipose tissue is a better biomarker than serum for evaluating the long-term exposure of organochlorines.

The study was to investigate the functional properties of soy protein isolate hydrolyzed by immobilized α-chymotrypsin and the quality characteristics of soy ice cream made by the soy protein isolate treated with immobilized α-chymotrypsin. Up to the hydrolysis rate of 22.9%, treatement by immobilized α-chymotrypsin costed more time than that of α-chymotrypsin. Foam and emulsion capacity were decreased by the number of repetitive usage. Apparent viscosity and overrun of soy ice cream treated with immobilized α-chymotrypsin and α-chymotrypsin were shown similar tendency. In the sensory characteristics, soy ice cream by enzyme treatment was evaluated as much acceptable than untreacted soy ice cream in the item of beany flavor, icy feel and overall quality. For efficient use of immobilized α-chymotrypsin industrially, α-chymotrypsin immobilized on glass beads can be reused for about 11 times more than α-chymotrypsin.

Rho, Jung Hee,Kim, Jae Sook,Kim, Sang Yong,Kim, Soon Ki,Choi, Yoon Mi,Kim, Sung Min,Tchah, Hann,Jeon, In Sang,Son, Dong Woo,Ryoo, Eell,Cho, Kang Ho,Choi, Deok Young,Kim, Yoon Mi The Korean Society of Pediatric Gastroenterology 2013 Pediatric gastroenterology, hepatology & nutrition Vol.16 No.1

Purpose: Meckel's diverticulum (MD) has various clinical manifestations, and diagnosis or selectection of proper diagnostic tools is not easy. This study was conducted in order to assess the clinical differences of MD diagnosed by scintigraphic and non-scintigraphic methods and to find the proper diagnostic tools. Methods: We conducted a retrospective review ofthe clinical, surgical, radiologic, and pathologic findings of 34 children with symptomatic MD, who were admitted to Gachon University Gil Medical Center, Inha University Hospital, and The Catholic University of Korea, Incheon St. Mary's Hospital between January 2000 and December 2012. The patients were evaluated according to scintigraphic (12 cases; group 1) and non-scintigraphic (22 cases; group 2) diagnosis. Results: The male to female ratio was 7.5: 1. The most frequent chief complaint was lower gastrointestinal (GI) bleeding in group 1 and nonspecific abdominal pain in group 2, respectively. The most frequent pre-operative diagnosis was MD in both groups. Red blood cell (RBC) index was significantly lower in group 1. MD was located at 7 cm to 85 cm from the ileocecal valve. Four patients in group 1 had ectopic gastric tissues causing lower GI bleeding. The most frequent treatment modality was diverticulectomy in group 1 and ileal resection in group 2, respectively. Conclusion: To diagnose MD might be delayed unless proper diagnostic tools are considered. It is important to understand indications of scintigraphic and non-scintigraphic methods according to clinical and hematologic features of MD. Scintigraphy would be weighed in patients with anemia as well as GI symptoms.

<P><B>ABSTRACT</B></P> <P>To provide appropriate solutions for problematic smartphone use, we need to first understand its types. This study aimed to identify types of problematic smartphone use based on psychiatric symptoms, using the decision tree method. We recruited 5,372 smartphone users from online surveys conducted between February 3 and February 22, 2016. Based on scores on the Korean Smartphone Addiction Proneness Scale for Adults (S-Scale), 974 smartphone users were assigned to the smartphone-dependent group and 4398 users were assigned to the normal group. The data-mining technique of C5.0 decision tree was applied. We used 15 input variables, including demographic and psychological factors. Four psychiatric variables emerged as the most important predictors: self-control (Sc; 66%), anxiety (Anx; 25%), depression (Dep; 7%), and dysfunctional impulsivities (Imp; 3%). We identified the following five types of problematic smartphone use: (1) non-comorbid, (2) self-control, (3) Sc + Anx, (4) Sc + Anx + Dep, and (5) Sc + Anx + Dep + Imp. We found that 74% of smartphone-dependent users had psychiatric symptoms. The ratio of participants belonging to the non-comorbid and self-control types was 64%. We proposed that these types of problematic smartphone use may be used for the development of an appropriate service for controlling and preventing such behaviors in adults.</P> <P><B>Highlights</B></P> <P> <UL> <LI> Four psychiatric variables were the most important predictors of problematic smartphone user: self-control, anxiety, depression, and dysfunctional impulsivities. </LI> <LI> There are five problematic smartphone use types: (1) non-comorbid, (2) self-control, (3) Sc + Anx, (4) Sc + Anx + Dep, and (5) Sc + Anx + Dep + Imp. </LI> <LI> 74% of smartphone-dependent users have psychiatric symptoms.
