이 연구는 한국불교의 대표적인 포교 성공사례 중 한 곳인 한마음선원을 대상으로 포교 성공요인과 위험요인을 분석한다. 연구자는 일반적인 관점 과는 다른 관점, 즉 성공요인보다는 위험요인에 주목한다. 이를 위해 성 공적인 포교 사례들을 개별적이고 독립적인 사례들로서 주목하여 각각의 사례에서 성공 요인을 분석하는 기존 방법론이 아닌 새로운 방법론을 제 시한다. 대략적으로 정리하면, 성공사례들 속에서 공통적인 ‘성공적인 포 교 조건’을 정리하고, 특정한 사례(이 연구에서는 한마음선원)를 대상으로 성공적인 포교 조건 중에서 가장 취약한 것이 무엇인지 점검하고 그 대 안을 찾는다. 성공적인 포교 조건은 조직 요소와 전법 활동요소로 구성되 며, 불교조직의 요소는 불법승의 체계를 갖춘다. 첫째, ‘불’을 의미하는 사찰지도자의 리더십. 둘째, ‘법’을 구축하기 위한 것으로 사찰지도자의 이념과 그 이념을 전달하는 교육체계, 셋째, ‘승’을 위한 사찰지도자의 이 념을 반영한 운영체계와 신도조직이다. 그리고 전법 활동은 교화를 지향 하는 포교와 ‘법’의 실천과 요익중생의 구체화인 사회적 실천으로 구분할 수 있다. 특히 전법활동은 사회와 사찰이 만나는 접점으로 사회적ㆍ지역 적 요구를 반영해야 성공적인 포교 활동이 가능하다. 선행연구와 한마음 선원의 자료를 통해 현재 한마음선원은 포교 조건을 충족하고 있음을 확 인하였다. 그리고 위험요인으로는 대행스님 리더십의 새로운 정리와 계 승, 사회활동을 검토하였다.

The purpose of study was to examine the factors influencing fast food consumption in Korean adolescents. The analysis was conducted using cross sectional study data from the 16th Korea Youth Risk Behavior Web-based Survey in 2020. A total 54,948 middle and high school students participated in this study. The subjects in the analysis were 28,353 males and 26,595 females, 28,961 middle school and 25,987 high school students. In total, 56.6% Korean adolescents consumed fast food once or twice weekly and 25.4% consumed fast food more than three times weekly. Logistic regression analysis revealed that fast food consumption was significantly associated with dietary behavior such as lower breakfast intake (OR: 0.930, 95%CI: 0.891~0.970, p<0.001), higher soda drinks consumption (OR: 2.563, 95%CI: 2.452~2.678, p<0.001), and higher sweet drinks consumption (OR: 1.898, 95%CI: 1.818~1.982, p<0.001). For psychological and health behavior factors, fast food consumption was also significantly associated with higher perceived stress (OR: 1.239, 95%CI: 1.163-1.321, p<0.001), higher smoking (OR: 1.300, 95%CI: 1.164~1.453, p<0.001), higher drinking (OR: 1.193, 95%CI: 1.112~1.280, p<0.001), higher depression experience, higher loneliness experience, and lower subjective health, In conclusion, fast food consumption in Korean adolescents was associated with undesirable dietary habits and psychological and health behavior, suggesting that appropriate education programs are necessary to reduce such behavior.

The water consumption data of individual consumers must be analyzed and forecast to establish an effective water demand management plan. A k-mean cluster model that can monitor water use characteristics based on hourly water consumption data measured using automated meter reading devices and demographic factors is developed in this study. In addition, the quantification model that can estimate the daily water consumption is developed. K-mean cluster analysis based on the four clusters shows that the average silhouette coefficient is 0.63, also the silhouette coefficients of each cluster exceed 0.60, thereby verifying the high reliability of the cluster analysis. Furthermore, the clusters are clearly classified based on water usage and water usage patterns. The correlation coefficients of four quantification models for estimating water consumption exceed 0.74, confirming that the models can accurately simulate the investigated demographic data. The statistical significance of the models is considered reasonable, hence, they are applicable to the actual field. Because the use of automated smart water meters has become increasingly popular in recent year, water consumption has been metered remotely in many areas. The proposed methodology and the results obtained in this study are expected to facilitate improvements in the usability of smart water meters in the future.

The purpose of this study is to analyze which factors affect safety awareness of foreign workers and international students. In the correlation analysis, individual characteristics related to the safety awareness of foreign workers were nationality, status of stay(visa types), place of work, educational background, and Korean proficiency while international students were relevant with only the types of residence. There were significant differences in the safety awareness of foreign workers in nationality, status of stay(visa types), region of residence, educational background, place of work, and Korean proficiency. However, there was a significant difference only in the types of residence for the international students. In the regression analysis of factors affecting safety awareness, there were significant differences in nationality, status of stay(visa types), place of work, and Korean proficiency in the case of foreign workers. It was analyzed that nationality and status of stay had a negative (-) effect, and the place of work and Korean proficiency had a positive (+) effect. In the case of international students, it was analyzed that only the types of residence had a negative (-) effect on safety awareness.

As modern society has emerged and developed, the subway has established itself as a representative means of transportation in the city due to its speed, accuracy, and accessibility. According to the Indoor Air Quality Management Act, underground stations have established and managed the maintenance and recommendation standards for PM10, PM2.5, CO2, CO, HCHO, NO2, Rn, VOCs However, th the standards for airborne mold has not been applied for subway stations even though management for the health effect of exposure to mold is necessay. In this study, the correlation with major contributing factors was analyzed by measuring the concentration of airborne molds in the indoor air of underground stations and through literature research. It was confirmed that there was a correlation between the concentration of airborne molds in subway stations and the major contributing factors. As a result of the analysis, it was found that the concentration of airborne molds became higher as the location of the platform became deeper underground, during periods of congestion, and especially in summer. There was no significant correlation with the year of construction. Our findings indicate that appropriate management measures should be devised in response to such contributing factors.

Purpose: Given the rapid aging of the population in Korea, many studies have emphasized the community efforts to slow down or prevent frailty of older adults who are living alone. However factors that affect frailty among older adults living alone remain unclear. This study aimed to identify the factors affecting frailty among community-dwelling older adults living alone. Methods: This secondary data analysis used data of 126 older adults who are living alone. Levels of frailty, depression, social activity and social support were self-reported and physical function (Timed up and go test results and handgrip strength) were measured. Data were analyzed with descriptive statistics and multiple linear regressions. Results: The overall mean score for frailty was 5.13 out of 20. Age, timed up and go test results, and social support were found to be statistically significantly associated with the frailty of older adults living alone. Conclusions: Identification of significant physical and social factors affecting frailty among older adults living alone is beneficial for developing community-based healthcare. The development of community-based multi-component intervention or facilitating home-visit nursing care should be considered to slow down frailty and promote good health.

PURPOSES : In this study, we quantitatively prove the rubber necking phenomenon for highway traffic accidents and develop a calculation model based on the influencing factors. METHODS : Vehicle detector speed data in the opposite direction to the accident point were used based on the accident data on highways over the past three years, and a comparative verification was performed between nearby vehicle detector data to verify the reliability of the data. Accordingly, a binomial logistic model, ordinal probit regression model, and multilinear regression model were developed to compare the orientation. RESULTS : There was a difference in the influencing factors based on the dependent variable, and the day of the week, vehicle type, weather, longitudinal slope, and median height had an effect. Through a regression analysis, an influence coefficient was derived to calculate the driving speed deceleration value by rubbernecking. The results of the model analysis proved that the speed reduction caused by rubbernecking was more evident during the daytime than at night, during weekends compared to weekdays, and the speed reduction was more obvious for heavy vehicles compared to other types of vehicles. It can also be concluded that longer clearance time, higher accident severity, and higher traffic volume affect traffic delay. To verify the data and model equation, the mean prediction bias (MPB) and mean absolute deviation (MAD) were calculated for hundred cases randomly extracted from the collected accident data. These results were excellent. CONCLUSIONS : It can be developed into a human-engineered model that reflects various road/facility conditions, such as highways, other lanes, general roads, and roads without a median strip. This study is meaningful as a basic study on the quantitative effect of rubber necking.

PURPOSES : The objective of this study is to investigate the spatiotemporal factors influencing the waiting time of special transportation systems for disabled people in Seoul, Korea. METHODS : A parametric survival analysis was employed to identify the primary factors influencing longer waiting times, primarily because censoring data were included in the analysis. For the analysis, one-year historical data collected from the Seoul Call-taxi for the disabled in 2019 were used. Using normal probability plots and Anderson-Darling statistics, a log-normal model was estimated to fit the data. RESULTS : In terms of time, there was a time zone in which the service level in terms of waiting time, such as late-night and dawn, decreased depending on the time of day called by call taxi users with disabilities in Seoul. Moreover, the waiting time on weekends was shorter than on weekdays. Spatially, when a user requests a service, there are many nearby vehicles when the traffic conditions nearby are good, and the waiting time tends to decrease near the depot. CONCLUSIONS : The existing system needs to reflect the increase in vulnerable times and the improvement of the dispatch method, considering the difference in the primary purpose of travel on weekdays and weekends. Additionally, to resolve the phenomenon in which vehicles are concentrated in a specific area, waiting time can be improved using operational strategies that can uniformly distribute vehicles in space, such as spatial subdivision of depots, real-time monitoring, and relocation.

PURPOSES : The objective of this study is to develop regression models for surface distress (SD), rut depth (RD), and international roughness index (IRI) of Jeju Island local road by analyzing the correlations between the pavement performance and its influencing factors. METHODS : First, the differences between pavements in inland Korea and Jeju Island in terms of performance and influencing factors were investigated. Influencing factors were assigned to pavement sections on Jeju Island using the inverse distance weighting method, and the correlations between the pavement performance and influencing factors were analyzed. As a result, maximum temperature, heat wave days, annual temperature range, precipitation days, precipitation intensity, ESAL, etc. were determined as independent variables for the pavement performance prediction models. Multiple regression analysis was performed to develop the pavement performance models using the selected independent variables. RESULTS : The RD, maximum temperature, and precipitation days were determined to be the independent variables for the SD predictive model. The SD, maximum temperature, annual temperature range, heat wave days, and precipitation days were selected as independent variables of the RD prediction model. In addition, the RD, annual temperature range, heat wave days, precipitation days, and ESAL were selected as independent variables for the IRI prediction model. CONCLUSIONS : As a result of the study, an actual forecast model for SD, RD, and IRI was developed. Based on this model, it is possible to estimate the predictive value of the missing performance data in the studied interval. If the factors affecting performance are managed in terms of maintenance beyond a certain level, it can help those responsible for road maintenance to rationally select the maintenance method and timing.

이 글은 한국정치 초유의, 국민이 불러낸 윤석열 야당 후보가 정치 입 문 8개월 만에 대통령에 당선되었다는 점을 정치외부자적 관점에서 논의 하고자 한다. 이런 관점에서 보면 정권교체는 문재인 정부에 대한 국민 적 심판을 의미하는 것이며, 단지 이재명 후보의 대선 도전에 대한 심판 이 아니다. 이에 대한 연구방법으로는 SWOT 분석 모델을 중심으로 하 되, 제20대 대선 관련 연구가 일천한 관계로 신문 자료나 인터넷 자료를 여야간 정권교체 과정으로 고찰하고자 한다. 윤석열 당선인은 유효 투표 의 48.56%인 1,639만여 표를 얻어 47.83%를 득표한 이재명 더불어민주 당 후보(1,614만여 표)를 약 0.73%차로 따돌렸다. 이로써 문재인 정부는 촛불시위로 정권교체 후 오만한 정권색깔을 드러내다 5년 만에 권력승계 실패로 퇴장하게 됐다.

제20대 대통령선거는 더불어민주당의 이재명 후보와 국민의힘의 윤석열 후보가 후보자의 자질 논란 등으로 역대급 비호감 선거로 인 식되었고, 정권재창출과 정권교체의 충돌, MZ세대에서 비롯된 세대 와 성별을 둘러싼 대립양상 등으로 초박빙의 선거였다. 제20대 대통 령선거에서 국민의힘의 윤석열 후보가 48.56%를, 더불어민주당의 이 재명 후보가 47.83%를 얻어 0.73% 차이로 윤석열 후보가 대통령에 당선되었다. 이에 제20대 대통령선거에서 더불어민주당의 이재명 후 보가 실패한 원인을 검토하면 다음과 같다. 첫째, 대장동개발비리의 혹에 대한 거듭된 말바꾸기와 책임전가식의 방어적 변명이 후보자에 대한 신뢰성을 약화시켰다. 둘째, 코로나19로 국가재정이 악화되는 상황에서 기본소득제에 대한 논란은 국민정서와의 부합성에서 한계를 보였다. 셋째, 정권교체에 대한 국민적 관심사를 정치교체와 국민통 합정부로 희석시키려는 수사적 표현은 국민을 설득하지 못하였다. 결 국 제20대 대통령선거에서 더불어민주당의 이재명 후보는 후보자의 자질논란, 국민정서와 부합되지 않는 기본소득제, 정권재창출에 대한 부정적 인식을 극복하지 못해 낙선한 것으로 보인다.

Recently, concern regarding disposal of cellulosic material is growing as cellulose is known to produce complexing agent, isosaccharinic acid (ISA), upon degradation. ISA could enhance mobility of some radionuclides, thus increasing the amount of radionuclide released into the environment. Thus, evaluation on the possible impact of the cellulose degradation would be an important aspect in safety evaluation. In this paper, safety assessments conducted in Sweden and UK are studied, and the factors required to be considered for appropriate safety assessment of cellulose is analyzed. SKB (Sweden) conducted safety assessment of cellulose degradation as a part of long-term safety assessment of SFR. SKB determined that ISA would impact sorption of trivalent and tetravalent radionuclides (Eu, Am, Th, Np, Pa, Pu, U, Tc, Zr and Nb) at concentration higher than 10−4–10−3 M, and impact sorption of divalent radionuclides (Ni, Co, Fe, Be and Pb) at concentration higher than 10−2 M. Then, SKB conservatively set the upper limit of ISA concentration to be 10−4 M and conducted cellulose degradation evaluation on each waste package type, considering the expected disposal environment of SFR. Based on the calculated results, some of the waste packages showed concentration of ISA to be higher than 10−4 M, so SKB conservatively developed waste acceptance criteria to prevent ISA being produced to an extent of affecting the safety of the repository. SKB conducted safety assessment only for the repositories with pH above 12.5 and excluded 1BLA from the safety assessment as the expected pH of 1BLA is around 12, which is insufficient for cellulose to degrade. However, SKB set disposal limit for 1BLA as well, to minimize potential impact in future. Serco (UK) conducted safety assessment of cellulose degradation for the conceptual repository, which is a concrete vault with cementitious backfill. Serco estimated that the pH of repository would maintain around 12.4. Serco conservatively assumed that the pH would be sufficient for cellulose degradation to occur partially, and suggested application of appropriate degradation ratio for safety assessment of cellulose degradation. To conduct appropriate safety assessment of cellulose degradation, an appropriate ISA concentration limit based on radionuclide inventory list, and an appropriate cellulose degradation ratio based on the pH of disposal environment should be determined. As for guidance, below pH 12.5, cellulose degradation is not expected, and between pH 12.5–13, partial cellulose degradation is expected. In future, this study could be used as fundamental data to evaluate safety of the repository.

본 연구는 한국의 다문화 청소년 및 일반 청소년의 건강위험행위와 폭력피해경험을 비교하고 폭력피해 경험과 관련된 요인을 건강위험행위를 중심으로 규명하고자 하였다. 제15차 청소년 건강행태 온 라인 설문조사(2019)의 자료를 사용하여 35,574명의 청소년을 대상으로 하였다. 자료 분석은 SPSS/Win 22.0을 사용하여 복합 표본 분석을 하였다. 연구 결과, 다문화청소년은 일반청소년보다 흡연, 습관적 약물 사용, 폭력피해 경험이 유의하게 더 높았다. 다문화청소년과 일반청소년 모두 가족과 함께 거주하지 않을 수록, 흡연경험과 습관적 약물사용 경험이 많을수록 폭력피해경험이 더 많았다. 일반청소년의 폭력피해경 험은 성별, 학력, 경제적 상태, 음주경험과 유의한 관련이 있었다. 따라서 다문화 청소년과 일반 청소년의 폭력피해 경험을 예방하기 위해서는 가족과 함께 살지 않는 청소년에 대한 사회적 지원이 필요하며, 흡연 및 습관적 약물 사용 경험이 있는 청소년에 대한 세심한 주의가 필요하다. 또한 다문화 청소년은 일반 청소 년에 비해 건강위험 행위와 폭력피해에 더 취약하므로 다문화청소년의 올바른 건강행위 실천과 폭력피해 경험을 예방하기 위한 교육 프로그램이 필요하다.

Ppuri or Root technology primarily includes technologies such as casting, mold, plastic working, welding, heat treatment and surface treatment. It is regarded as an essential element for improving the competitiveness of the quality of final products. This study investigates the current status of smart factory implementation for Ppuri companies and analyzes the influencing relationships among various company factors. The factors affecting smart factory implementation for Ppuri companies are sales, exports, number of technical employees, and holding corporate research institutes. In addition, this research shows that even if smart factory implementation is pursued for data collection, data utilization is not implemented properly. Thus, it is suggested that the implementation of smart factories requires not only the availability of facilities and systems but also proper data utilization.

The purpose of this study was to identify nutrition quotient for elderly (NQ-E) and to investigate factors affecting NQ-E of the elderly using welfare center and senior citizen’s center in Changwon city. A self-administered questionnaire was conducted between June 2021 and early August 2021 for 320 elderly (≥65 years, male, n=52, female, n=268). As a result of the survey, the mean NQ-E score was 61.12, which was within the medium-high grade. The scores of balance, moderation, and dietary behavior factors were within the medium-high grade, while diversity factor was within the medium-low grade. According to the results of the Pearson’s correlation coefficient analysis, NQ-E showed positive correlations with the ‘with family’ (p<0.01), ‘education level’ (p<0.01), ‘health functional foods consumption’ (p<0.01), ‘monthly household income’ (p<0.05), ‘nutrition education experience’ (p<0.05), ‘reading nutrition labeling of health functional foods’ (p<0.01), ‘perception of the efficacy of health functional foods’ (p<0.01), and ‘the number of times of leisure activities per week’ (p<0.01) and negative correlations with the ‘gender’ (p<0.05), ‘age’ (p<0.01), ‘smoking’ (p<0.05), and ‘social frailty’ (p<0.01). As a result of multiple regression analysis, ‘gender’ (p<0.05), ‘perception of the efficacy of health functional foods’ (p<0.05), ‘the number of times of leisure activities per week’ (p<0.05), and ‘social frailty’ (p<0.05) were found to be factors affecting NQ-E. Based on the results of this study, customized services by characteristic, nutrition education, and counseling for the elderly should be implemented and the development of various programs and continuous support of the community are necessary so that the elderly can carry out social exchange.
