In this study, the Korea National Health and Nutrition Examination Survey in 2016 examined the nutrient and food intake of women in their 20s and 30s according to the number of meals a day, and the results were as follows: The study included 256 women in their 20s and 474 women in their 30s. Women in their 20s and 30s ate two meals a day, indicating that the notion of three meals a day was gradually changing to two to three meals a day. Those in their 20s and 30s who eat one, two or three meals a day were consuming less than the estimated energy requirement of the DRI for Koreans 2015. The vitamin A and C were eating less than the recommended intake in all meals. In the case of minerals, calcium was taken less than the recommended intake in all meals, but sodium was taken above the goal intake in all groups. Women in their 20s and 30s must reduce their intake of saturated fatty acids and sodium, and increase their intake of vitamins A, C, calcium, and potassium. Women in their 20s and 30s drank a lot of coffee, ate baechu-kimchi and rice frequently per week.

Background: Health-related quality of life (HRQOL) is a construct of quality of life relevant to health. HRQOL can be measured multiple ways including self-perceived interpretation of one’s health status. Research has shown value in understanding self-perceived or person-centered HRQOL. Thus, these types of assessments have been integrated into health care systems, used to help patients set personal goals and to determine treatment success. The purpose of this study was to describe the group, examine the relationship between HRQOL and functional independence, and then determine the impact of standard care on the HRQOL (index and visual analog scale [VAS]). Methods: Retrospective clinical observation study. Descriptive statistics used to describe the stroke sample. Comparison was performed to explore the correlation between the EuroQol 5-Dimensions Questionnaire (EQ-5D) and the Functional Independence Measure (FIM) at admission and discharge. Paired-samples t-test was conducted to evaluate the impact of standard therapy on HRQOL on EQ-5D. Results: n=1325; mean age of 72 years (SD=13.28) and 65% females. A weak, positive correlation found at admission (r=.15, n=1325, p<.000) and discharge (r=.04, n=1325, p<.000). A paired-samples t-test revealed a statistically significant increase in HRQOL index and VAS scores (p’s<.000) overtime, with a large effect size (η2=.74 and .70), respectively. Conclusion: A weak relationship was present between HRQOL and functional independence, thus suggesting these assessments should be used independent of each other. Statistically significant change in scores suggest improvement in HRQOL overtime, supported by large effect sizes and mean scores higher than the minimal important difference range.

군집지수와 FD와의 상관분석 결과 FD는 군집지수 중 Shannon 다양도와 가장 높은 상관성을 보였다. 조사지점은 환경 특성에 따라 6개의 그룹으로 나누어졌으며, 고도에 따라서 뚜렷한 차이를 보였다. 이에 따라 고도가 높은 그룹 1은 산림의 비율이 많고 좋은 수질을 보였으나 고도가 낮은 그룹 6은 수질이 양호하지 않았다. 환경 구배에 따른 조사지역 그룹과 군집지수와 FD의 연관성 분석을 위해 NMDS를 시행하였으며 그룹 1~3에서 FEve를 제외한 모든 지수가 높았다. 그룹 간의 종구성은 그룹 1~3에는 하루살이목, 날도래목, 강도래목이 높았으며, 그룹 4, 5에는 잠자리목, 딱정벌레목이 주요하게 나타났다. 생물학적 형질은 그룹 1~3에서 생식기간이 길고, 이동성이 낮은 형질 특성을 보였으며 생물의 저항력 전략을 잘 보여주었다. 반대로 그룹 4~6은 생식기간이 짧고, 이동성이 높은 회복력의 전략을 뚜렷하게 반영해 주었다. 수질의 오염도가 낮은 상류는 교란의 빈도가 적고 공간적으로 높은 이질성을 가졌으며 생물이 주로 저항성 전략을 보였으며 생물이 서식지에 오래 머무를 수 있어 기능적, 구조적 생물다양성이 높게 나타났다. 반대로 수질의 오염도가 높은 하류는 교란의 빈도가 높고 공간적으로 균질성이 높으며 생물은 주로 회복력의 전력을 보여 교란에 의해 이동하거나 회피할 수 있는 휴면기, 고치, 세포, 알 등의 독특한 형태를 갖는 반면 생물다양성은 낮게 나타났다. 본 연구를 통해 저서성 대형 무척추동물의 기능적 다양성은 수서 생태계 환경과의 관계를 잘 설명해 주었다. 따라서 생물의 형질을 이용한 기능적 다양성은 잠재적으로 수생태계 건강성 평가에 효과적으로 이용될 수 있을 것이다.

본 연구는 훼손된 하천 수생태계의 훼손원인을 식별하고 그 전이 과정을 규명하기 위해 수생태계 훼손원인 진단체계를 구축하고 정책적 활용 가능성을 보고자 하였다. 수생태계 현황 조사 및 건강성 평가결과는 하천의 훼손에 대한 전반적인 상황을 알 수 있어 하천 복원 및 관리의 판단 근거로 사용된다. 그러나 하천이 훼손된 원인이나 훼손이 발생하게 된 전이 과정을 고려하지 못한다는 한계를 가진다. 따라서 본 연구에서는 과학적이고 체계적인 진단체계를 제안하여 훼손원인과 그 전이 과정을 규명하였다. 미국, 호주, 유럽의 사례를 분석하여 우리나라에 맞는 진단체계를 제안하였다. 총 8단계로 구성되며, 기초자료 조사, 하천 수생태계 훼손 판단, 훼손 구간 설정, 훼손 유형화 및 잠재적 훼손원인 도출, 본 조사, 주 훼손원인 진단 및 최적 훼손 모델 도출, 종합분석 및 하천 복원방안으로 이루어져 있다. 이러한 진단체계는 하천 생태계의 복잡하고 다양한 특성을 고려하여 훼손원인을 파악할 수 있으며 하천 복원 및 관리 방안을 제시하여 효율적인 의사결정을 지원할 수 있다.

There is only limited evidence for the association between fruit and vegetable consumption and mental health in Korea. This study examined the relationship between fruit and vegetable consumption and mental health according to physical activity among Korean adult women. Based on data of the Korean National Health and Nutrition Examination Survey (2014-2016), a total of 5,332 participants were included in this analysis. With increasing fruits and vegetables consumption, the prevalence of depressive mood was significantly decreased (p for trend=0.0248). The prevalence of stress perception (p for trend=0.0422) and the prevalence of depressive mood (p for trend=0.0300) were decreased with increasing fruit consumption. The prevalence of depressive mood was significantly decreased when fruit and vegetable consumption (p for trend=0.0370) and fruit consumption (p for trend=0.0356) were increased for those Korean women with low intensity of physical activity. For the obesity group (Body mass index 25 kg/m2), the prevalence of depressive mood was decreased with increasing fruit and vegetable consumption (p for trend=0.0111) and increasing fruit consumption (p for trend=0.0165). In conclusion, fruit and vegetable consumption were associated with mental health according to physical activity among Korean adult women. Further prospective studies are warranted to explore the association between fruit and vegetable consumption and mental health among Korean adult women.

The purpose of this study was to analyze a cohort, age, and time effects on sodium and sodium-calorie intake using the 2007~2017 Korea National Health and Nutrition Examination Survey (KNHANES). For analysis, we have constructed cohort panel data that combine KNHANES data in a time series. The age effect gradually increased from age 45~49 and then decreased afterwards. The time effect showed an increase in average sodium intake until 2010 followed by a subsequent decrease. The cohort effect showed that the sodium intake was the highest for the War of Liberation 1946~1953, and that the younger the latter, the lower the sodium intake. According to a cohort analysis, the younger the generation, the lower the sodium intake compared to the calorie intake, according to the baby boomers. Based on the results of this study, efforts should be made to educate and promote the dieting and providing low-salt meals to reduce sodium intake by generation. An analysis of the health hazards including sodium by generation and age is thought to enable the establishment relevant policies.

Smart healthcare clothing combines IoT, new technology, and clothing construction to perform specific care functions, and its utility has been expanding rapidly within aging and diversified societies. However, the related market remains at an early stage of development due to limited regulation, lack of consumer awareness, and the need for not only technical development but promotion plans for potential users. This paper aims to analyze factors influencing purchase intention for smart healthcare clothing with biosignal monitoring, including variables in the Technology Acceptance Model (TAM), clothing attributes, health-related lifestyle factors, and fashion innovativeness. A survey was conducted on a sample of 300 males and 300 females ranging in age from 20 to 50 years, and data were analyzed using SPSS 21.0. The results show that perceived usefulness, perceived aesthetic attributes, health responsibility, and fashion innovativeness were overall significant predictors of using smart healthcare clothing. Additionally, perceived ease of use and physical activity in the male subsample, and perceived compatibility within the female group, also had significant effects. Furthermore, age was a determining factor; for subjects in the 30s age group, perceived usefulness, compatibility, and health responsibility had significant positive associations. The results of this study can provide basic guidelines for designing merchandising plans to expand user acceptance of smart healthcare clothing.

This study examined the difference of dietary intake behavior between groups of adults aged >20 years with or without dyslipidemia, and comparing the various types of dyslipidemia, based on the Seventh (2016) KNHANES. Men showed higher rate for triglyceridemia and LDL-cholesterolemia than women and subjects in the age group 50-59 years exhibited the highest incidence of triglyceridemia, total cholesterolemia and HDL-cholesterolemia. The ratio of obese people was higher in most types of dyslipidemias. The top five foods in each group of cereal & grain, meat, vegetable, and fruit were selected for analysis, based on the food frequency. The dyslipidemia group showed higher intake frequencies for mixed grains, cabbage kimchi and leafy vegetable than the no-dyslipidemia group, and the group with high blood total cholesterol for mixed grains, apple, and cutlassfish-croaker. Group with high blood triglyceride showed higher intake frequencies of rice and mackerel-mackerel pike than the other groups of high blood triglyceride. No food showed significant difference in the frequencies between groups of LDL-cholesterol. Group with high blood HDL-cholesterol showed higher intake frequency of bibim-fried rice, deep fried chicken, stir fried chicken, apple, tangerine, banana and butter-margarine. These results indicate that people with high levels of blood total cholesterol are more concerned with food having health benefits than those with abnormal levels of other blood lipid. More information on dietary benefits need to be provided to patients having high levels of triglyceride, LDL-cholesterol and HDL-cholesterol.

In this study, 38 residents of the Jeonnam areas in Korea were assessed for their level of exposure to VOCs. The aim was to understand the difference in levels of indoor, outdoor, and personal exposure to VOCs (benzene, toluene, ethylbenzene) and a health effect assessment was conducted to determine whether there was any fatal cause from carcinogenic or non-carcinogenic elements from case and control group. Personal exposure to benzene showed a higher distribution than indoor and outdoor concentrations, and it was found that the average concentration of the case group was higher than that of the control group in all indoor, outdoor, and personal exposures. With regard to benzene, in the CTE, RME, and Monte-Carlo analysis, all subjects in the case group were seen to exceed the lifetime cancer risk of 10−6 defined by the US EPA and in the RME analysis the control group subjects were also seen to exceed the lifetime cancer risk of 10−6 defined by the US EPA. In the case of toluene, ethylbenzene on the CTE, RME, and Monte-Carlo analysis, the non-carcinogenic standard of 1 was not exceeded.

Fatigue is not a trivial issue and needs much attention. On the other hand, fatigue among seafarers could lead to accidents at sea due to their inability and ineffectiveness in carrying out their work. Some were caused by sleepiness and lack of vigour, which, could not only affect their safety but compromising on other seafarers as well. In this study, factors that cause fatigue among seafarers were examined analytically and their quantitative priorities were determined using Analytic Hierarchy Process (AHP) method. Additionally, the Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS) is used to identify the best alternatives in minimizing fatigue among seafarers. For this, data is collected through interview involving those working in academic and maritime industry with more than 5 years of experiences in dealing with seafarers. The AHP result shows that fitness is the main cause that could affect fatigue on seafarers’ reliability. Besides, TOPSIS result shows that a well-maintained shipboard is the best way in sustaining seafarers’ energy. In sum, fatigue among seafarers could influence on safety and may lead towards precarious health issue over a long-term.
