We performed a study to examine the association between diet quality and nonalcoholic fatty liver disease (NAFLD). Our study included 3,586 women aged 40-64 years who participated in the sixth Korea National Health and Nutrition Examination Survey. The study subjects were classified into the NAFLD group (n=816) and the normal group (n=2,770) using the hepatic steatosis index. The anthropometric indices, blood profiles, and dietary intake data of the subjects were obtained. The waist circumference, body mass index, and the serum levels of triglycerides, fasting blood sugar, HbA1c, and systolic and diastolic blood pressures were higher in the NAFLD compared to the normal groups (p<0.001, respectively). The intakes of protein (g/kg body weight, p<0.001), potassium (p<0.001), and vitamin A (p=0.006) were significantly lower in the NAFLD group. It was observed that the higher the total Korean Healthy Eating Index score, the lower the risk of NAFLD. A reverse relationship was shown between the NAFLD risk and the intakes of total fruits, total vegetables, vegetables excluding Kimchi and pickled vegetables, meat, fish, eggs and beans. Therefore, it is recommended that middleaged women in Korea increase their intakes of fruits, vegetables, and foods high in protein for the proper management of NAFLD.

In this research, we examined the shifts in determinants influencing the frequency of eco-friendly food purchases pre- and post-COVID-19. Our analysis utilized filtered 2019-2021 Consumption Behavior Survey data from the Korea Rural Economic Institute Food, excluding any irrational responses. Given the nature of the dependent variable, a multinomial logistic regression model was employed with demographic factors, variables pertaining to food consumption behavior, and variables concerning food consumption awareness as predictors. Following the onset of the COVID-19 pandemic, an individual's level of education was observed to positively influence the frequency of eco-friendly food purchases. In contrast, income level and fluctuations in food consumption expenditure did not appear to have a discernible impact on the purchasing frequency of such eco-friendly products. Irrespective of the advent of COVID-19, variables such as the frequency of online food purchases, the utilization of early morning delivery services, dining out frequency, and the intake of health-functional foods consistently demonstrated a positive correlation with the propensity to purchase eco-friendly foods. Overall, consumers prioritizing safety, quality, and nutrition over price, taste, and convenience in their procurement decisions for rice, vegetables, meat, and processed foods exhibit an increased inclination toward the acquisition of eco-friendly food products.

본 연구는 감정노동자 심리분석을 통한 심리치유 방향에 대한 연구이다. 본 연구의 목적 은 감정노동 심리치유 프로그램 개발에 기여 하고자 한다. 본 연구의 대상은 G도 북부지역 감정노동자 157명을 대상으로 설문조사를 하였다. 연구 기간은 2021년 4월부터 2023년 2 월까지 진행되었다. 자료 분석은 SPSS 28.0 통계프로그램을 이용하여 일원분산분석 (One-way ANOVA) 및 피어슨의 상관관계 분석(pearson correlation analysis)을 하였다. 연 구결과는 직군별 감정노동 수준은 M 3.03∼3.96, 감정노동 인식은 M 2.40∼3.48 유의미한 차이가 없는 상태로 나타났다, 감정노동 실태 면에서 1직군(M 2.81), 2직군(M 2.88)은 다른 직군과 M 0.68∼0.4의 차이를 보이는 등 언어적 폭력에서 더 취약한 결과가 나타났다. 감정 노동의 수준 정도에 따라 감정 부조화 및 손상-고객 응대 부조화 및 갈등 순으로 직업 불 만족에 영향을 주고 있다는 유의미한 차이를 볼 수 있다. 정신적 평가결과에서도 감정노동 으로 인해 감정소진, 의욕 저하 등 심리적 문제가 발생하고 있음을 알 수 있다. 이를 통해 향후 감정노동자 심리치유 발전에 기여하고자 한다.

Genderless fashion is a trend that involves clothing and accessories designed for anyone, regardless of gender identity, and may blur traditional gender boundaries by incorporating elements associated with men's or women's clothing. The trend is driven by changing attitudes towards gender, increasing awareness and acceptance of gender fluidity and non-binary identities, and a desire for more inclusive ways of expressing gender through fashion. Empirical evidence on how genderless or gender-neutral marketing efforts affect consumer response is limited. Our experimental study contributes to this literature by analyzing the role of clothing gender labels and consumer gender on purchase intention of clothing.

This study aims to investigate online commerce repertoire-based clusters and their characteristics with shopping values and commerce attributes. This study analyzes Nielsen panel log data that recorded nearly 6,000 panelists’ use of 48 major commerce websites and mobile applications. In addition, a survey was conducted with a sample of the panelists, which supplemented the behavioral data and provided cognitive and attitudinal data. Six commerce clusters were identified: “Social commerce centric,” “Secondhand centric,” “PC centric,” “scattered,” “Home-shopping centric,” and “Fashion centric". Also, “Hedonic” was statistically significant and “Quick delivery,” “Membership” are perceived to be effective. Also, there were discrepancies between the log and survey on usage. As online marketing and advertising driving conversion becomes critical, the understanding of online commerce repertoires and related consumer perceptions and characteristics should offer significant implications.

The main goal of the Korean VLBI Network Calibrator Survey (KVNCS) is to expand the VLBI calibrators catalog for KVN, KaVA(KVN and VERA Array), EAVN(East-Asian VLBINetwork), and other extended regions. The secondKVNCS (KVNCS2) aimed to detect VLBI fringes of new candidates for calibrators in the K band. Out of the 1533 sources whose single-dish flux density in the K band was measured with KVN telescopes (Lee et al. 2017), 556 sources were observed with KVN in the K band. KVNCS2 confirmed the detection of VLBI fringes of 424 calibrator candidates over a single baseline. All detected sources had a high Signal-to-Noise Ratio (SNR) of >25. Finally, KVNCS2 confirmed 347 new candidates as VLBI calibrators in the K band, resulting in a 5% increase in the sky coverage compared to previous studies. The spatial distribution was quasi-uniform across the observable region (Dec. > −32.5◦). In addition, the possibility as calibrator candidates for the detected sources was checked, using an analysis of the flux-flux relationship. Ultimately, the KVNCS catalog will not only become the VLBI calibrator list but is also useful as a database of compact radio sources for astronomical studies.

In this study, a survey focusing on the status of clothing interest, inconveniences resulting from clothing, preferred design items, etc. was conducted on 364 elderly women to suggest aesthetically and functionally appropriate indoor wear design for at home elderly women aged 60 years or older. The survey results showed that in general, the respondents’ interest in clothing was high, and more respondents in their 70s or older had difficulty in the action of opening and closing. With respect to considerations when purchasing clothes, color was considered more important than design as respondent’s age increased, and size was regarded as the most important factor especially among those in their 80s. The preferred top styles were T-shirts and blouses among those in their 60s and 70s, and T-shirts and shirts among those in their 80s. The preferred sleeve lengths were “below the elbow” and “above the wrist” in all age groups. The preferred sleeve hem type was “tightening” in all age groups. The most preferred bottom styles were “straight-leg pants” and “elastic waistband.” This study suggests the design items of indoor wear, including top, bottom, and overgarment for warmth, appropriate for elderly women at home based on the survey results. The study results are expected to serve as basic data necessary for the revitalization of the clothing industry for elderly women.

This study aims to understand the current status of exemptions for traffic accidents during the return of emergency vehicles and to provide suggestions for improvement. A survey was conducted on 3,500 firefighters to investigate the perception of traffic accidents during the return of emergency vehicles, and responses from 505 participants were analyzed. Based On the demographic characteristics and perception of the participants, frequency analysis and variance analysis were used as research methods to analyze basic statistics and the current situation. The results showed that firefighters have concerns and anxieties about traffic accidents during the return of emergency vehicles, and the need for applying exemptions and enacting explicit legal provisions was statistically confirmed. Based on these results, we suggest a policy for exemptions to improve the preparation for re-deployment and to alleviate the concerns and anxieties of firefighters.

Occupational safety and health management expenses in the construction industry are statutory and separately included in the cost statement to prevent occupational accidents and health problems. The expenses are determined by multiplying the standard amount by the rate decided according to construction types and scales. However, the current expense appropriation method does not properly reflect the recent changes in the construction industry such as industry size, industry diversification, and social atmosphere about safety reinforcement. This study surveyed 1579 questionnaires in total and analyzed expense execution rate and proportion of each expense category. The expense execution rate was relative higher in complex construction (e.g., heavy construction = 126%, civil engineering = 125%) and long-period project (equal to or over 48 months construction = 133%) compared to general construction (98~116%) and short-period project (less than 48 months construction = 115%). The proportion of spending expenses was higher in the category of safety manager labor costs (25~52%), safety facility costs (22~40%), and personal protective equipment costs (10~25%). The analysis results of the study can be utilized in revising the standard expense appropriation method by reflecting the current usages of the occupational safety and health management expenses in the construction industry.

This study was conducted to select target fish species as baseline research for accumulation analysis of major hazardous chemicals entering the aquatic ecosystem in Korea and to analyze the impact on fish community. The test bed was selected from a sewage treatment plant, which could directly confirm the impact of the inflow of harmful chemicals, and the Geum River estuary where harmful chemicals introduced into the water system were concentrated. A multivariable metric model was developed to select target candidate fish species for hazardous chemical analysis. Details consisted of seven metrics: (1) commercially useful metric, (2) top-carnivorous species metric, (3) pollution fish indicator metric, (4) tolerance fish metric, (5) common abundant metric, (6) sampling availability (collectability) metric, and (7) widely distributed fish metric. Based on seven metric models for candidate fish species, eight species were selected as target candidates. The co-occurring dominant fish with target candidates was tolerant (50%), indicating that the highest abundance of tolerant species could be used as a water pollution indicator. A multi-metric fish-based model analysis for aquatic ecosystem health evaluation showed that the ecosystem health was diagnosed as “bad conditions”. Physicochemical water quality variables also influenced fish feeding and tolerance guild in the testbed. Eight water quality parameters appeared high at the T1 site, indicating a large impact of discharging water from the sewage treatment plant. T2 site showed massive algal bloom, with chlorophyll concentration about 15 times higher compared to the reference site.

농촌진흥청에서 진행한 ‘왕귀뚜라미 돌보기 프로그램’으로 노인들의 우울증과 인지 기 능 개선을 통한 정서적 안정에 도움이 된다는 사실을 과학적인 방법을 통해 확인하고 이 를 관련 저명 학술지 제기하였다. 이를 바탕으로 본 연구는 전라북도 익산시에 거주하는 5세부터 10세까지 아동 50명을 대상으로 직접 만나 전문가의 자문을 받아 작성한 총 11 문항의 설문지를 활용하여 조사를 진행하였다. 설문조사는 소리 곤충에 대한 인식도는 높 았지만, 선호도와 사육 의향에서 부정적인 결과가 나왔다. 또한 소리곤충 중 귀뚜라미의 소리에 대한 문항에서는 긍정적인 결과가 나온 반면 여치의 소리에 대한 문항에서는 부정 적인 결과가 나왔다. 본 논문에서는 소리 곤충에 대한 아동의 인식도 및 선호도를 파악하 기 위한 설문조사 연구를 통해 관련 연구와 활동에 자료를 제공하고자 한다.

곤충은 지구상의 생물 중에서 가장 많은 종을 차지하고 있다. 또 인류보다도 훨씬 오래 된 지구의 선점자이며, 환경에 대한 적응력이 뛰어나 전 세계적으로 서식하고 있다. 현대 에 접어들면서 곤충은 사람들에게 식품(식용 곤충), 치유(소리, 정서곤충) 등의 다양한 효 과를 제공하고 있지만, 사람들은 그 효과에 대해서 잘 알지 못하고 징그럽다고 생각하는 것이 대부분이다. 그래서 우리는 곤충 중에서도 울음소리로 사람들의 마음을 치유하는 소 리곤충(귀뚜라미, 여치)를 주제로 본 연구를 하였다. 본 연구는 무작위의 성인 30명을 대 상으로 소리곤충(귀뚜라미, 여치)에 대한 인지 정도를 알아보고 실제 성인들이 소리곤충 (귀뚜라미, 여치) 울음소리의 효능에 대해서 알고 있는지, 알지 못한다면 그 효능에 대해 서 알리기 위한 것이 목적이다. 이에, 본 연구를 위하여 설문지 법을 사용하였으며, 대상 자는 무작위 대상의 남녀 30명(여:18, 남:12) 이었다. 설문조사 결과로는 응답자의 과반 수가 소리곤충 울음소리에 대해서 긍정적인 답변을 보였다. 하지만 소리의 호감도에 비해 직접 소리곤충을 키울 의향이 있다는 사람은 5명(20%)밖에 되지 않았다. 이에 성인들을 대상으로 귀뚜라미나 여치 등을 키우는 체험이 활성화된다면 더욱 긍정적인 결과가 나올 것으로 판단한다.

IAEA safety standards document and international programs (such as BIOMASS) related to the assessment of the biosphere around High Level Radioactive Waste (including Spent Nuclear Fuel) repositories require the assessment of the biosphere to use the assumption that the current natural environment and human society will be maintained, and at the same time, the evolution of the distant future changes also need to be taken into account. In Korea, which has not designated candidate disposal sites, it is necessary to investigate and predict the current state and future changes of the natural environment throughout Korea and apply it practically to Biosphere assessment (for BDCF derivation) for candidate disposal sites suitability assessment and Safety Case (for performance assessment) preparation for design, construction, operation, and post-closure management. To this end, the natural environment in the fields of Topography, Geology, Soil, Ecology, Weather and Climate, Animals and Plants, Hydrology, Ocean, Land-use, etc. and human society in the fields of Population Distribution, Spatial-Planning, Urban Form, Industrial-Structure, Lifestyle etc. are being investigated in the context of current status, past change records, and future change potential in the Korean Peninsula. This paper summarizes those investigations to date. This study referred Biomass-6 [IAEA] and National Atlas I (2019)/II (2020)/III (2021) [National Geographic Information Institute of the Korea Ministry of Land, Infrastructure and Transport].

To analyze the status and needs of the small- and medium-sized garment manufacturing industry in Busan, this study comprised an online survey of companies and interviews with 14 representatives of the 98 companies. The results are as follows: Approximately 34.7% of the garment manufacturers were located in Geumjeong-gu, Busan. The most common type of work was the contracting factory type. Daily production output was between 100pcs and 300pcs. Production materials comprised 42.9% woven and 24.8% knitted fabrics. Main products were menswear, uniforms, womenswear, casual wear, sports and leisure wear, protective clothes, and children’s clothing. The main clients were uniform companies, main factories, wholesale markets, online shopping malls and promotion companies, exporters, and department stores. As a result of a survey on industrial needs with company representatives, their satisfaction with company employees was 57.2%, and the most important factor when hiring employees was job-related competencies, among which the ability to understand the sewing process was the most necessary. In terms of computer software literacy, illustrations and pattern CAD/CAM are required. They thought industry-university cooperation is crucial for advantage for advantage research and product development, as it allows for the sharing knowledge, resources, and especially human resources. The greatest administrative issue were human resources and funding.

The labor environment in Korea has changed and problems related to employment types are treated as important issues. Especially, the ratio of irregular workers has not only increased relatively, but the labor conditions in Korea also have worsened in the current years. Studies have reported an association between temporary workers and the prevalence of diseases. However, there is insufficient research on chronic disease and employment types. Methods: The current study examines the prevalence rate of diseases and health behavior by categorizing employment types among Korean adults. Data were obtained from the 2016-2018 Korea National Health and Nutrition Examination Survey. Totally, the data of 2,366 workers (1,239 regular and 1,127 irregular) were analyzed in the study. The types of employment were classified by a questionnaire querying about working conditions. The results showed that irregular workers earned less than regular workers and had a significantly higher prevalence of diabetes mellitus and hypertension. We propose that if discrimination related to working conditions were relieved, irregular workers would be able to invest more time to exercise and doing check-ups regularly. In addition, individual nutrition consultations considering the knowledge and personal environmental factors of each individual are necessary for the improved health of all workers.

In this study, we examined the residual amounts of formaldehyde in hygiene products to determine the safety of these products in Gyeonggi-do. Formaldehyde is among the harmful substances that may remain within certain hygiene products. On the basis of an analysis of formaldehyde in a total of 222 items (6 disposable paper straws, 9 disposable paper napkins, 21 toilet papers, 13 disposable dishcloths, 16 disposable paper towels, 32 wet wipes for food service restaurants, 25 disposable cotton swabs, and 100 disposable diapers), we detected traces in three wet wipes for food service restaurants (1.87 to 4.45 mg/kg), which is approximately 9% to 22% of the standard level (20 mg/kg). We established that all the hygiene products assessed in the study met the individual standards for formaldehyde, thereby confirming that safe products are being distributed. In the standards and specifications for hygiene products, the formaldehyde test method is regulated for application with respect to three categories based on the type of product. The samples used in this study were of types for which method 1 or method 2 is applied, and the limits of detection, limits of quantification, linearity, and recovery rates were reviewed to verify the validity of each test method. When method 2 was applied, we experienced interference when performing analysis at a wavelength of 412 nm, which was associated with the influence of impurities in some samples of disposable cotton swabs and disposable diapers. Consequently, in these cases, the results were compared after analysis using method 1. By comparing the results obtained using method 2 with those obtained using method 1, the latter of which were unaffected by the interference of impurities, we were able to detect formaldehyde at low concentrations. These findings accordingly highlight the necessity to standardize the formaldehyde test method for future analyses.
