This study was to identify the effects of education on Korean foods preferred by elementary students and their sustainability. A survey was conducted on 5th-grade elementary school students. Korean food preferences were classified by exploratory factor analysis as creative, healthy, or considerate, and the effects of education on Korean dietary life were classified as cognitive or emotional. Dietary life sustainability was evaluated separately. Results showed that creative and considerate preferences had significant impacts on cognitive and emotional education effects and that a healthy preference type significantly impacted the emotional effect of education. Analysis showed that creative and considerate food preference types significantly influenced dietary life sustainability and that cognitive and emotional education effects mediated these relationships. Sex was not found to have a significant moderating effect. The study shows that Korean dietary life sustainability is influenced by education on topics that promote the value and excellence of Korean food and suggests that experiential education combining practice and theory should be used to increase interest in Korean food among elementary students. Additional studies are required to determine Korean food preferences to facilitate the development of a dietary life education program that enables students to understand and maintain healthy dietary practices.

This study aimed to determine the association between household types and healthy dietary practices among Korean adults. A cross-sectional analysis was performed using nationwide data on 23,488 participants from the 2017-2021 Korea National Health and Nutrition Examination Survey (KNHANES). Based on self-reported data, the participant household types were classified into single- and multi-person households. The adjusted odds ratios (AORs) and 95% confidence intervals (CIs) for healthy dietary practices according to household types were calculated by applying multivariable logistic regression analysis after adjusting for confounders. Of total, 11.21% and 88.79% were single- and multi-person households, respectively. Compared with individuals living in multi-person households, those in single-person households had lower odds of adhering to healthy dietary practices (AOR: 0.88, 95% CI: 0.79-0.98) and consuming adequate saturated fatty acids (<7% of energy) (AOR: 0.78, 95% CI: 0.69-0.88). In addition, men and individuals aged 65 years living in single-person households exhibited lower odds of consuming adequate saturated fatty acids and 500 g of fruit and vegetables per day than those in multi-person households. Single-person households often find it a challenge to practice a healthy diet. Hence, nutritional policies and educational support that help individuals living alone consume healthier diets are warranted.

The importance of urban green space creation is increasingly recognized as the most realistic and efficient approach for fine dust mitigation in urban areas. Particularly considering the characteristics of domestic cities, the application of buffer green spaces along roads can maximize the efficiency of fine dust reduction without the need for separate green space creation. Accordingly, this study analyzed the fine dust mitigation effects based on the types of plantings in the central dividers and roadside trees in Jeonju City, Jeollabuk-do. To do this, we controlled various external variables of urban space and considered the planting arrangement types in the central dividers, carrying out the analysis using a CFD simulation. The simulation results confirmed that the central dividers with plantings demonstrated more effective ultrafine dust reduction than those without. Moreover, the arrangement of roadside trees showed a greater ultrafine dust reduction effect when adopting a multilayered structure compared to a single layer. Based on these findings, we concluded that installing both trees and shrubs simultaneously in the central dividers and along roads was effective for ultrafine dust mitigation. On this basis, we quantified the dust reduction effects of plants in urban street environments and proposed planting guidelines for roadside green spaces to improve air quality.

본 연구의 목적은 청소년의 진로적응력의 잠재프로파일 유형과 사회적 지지인 양육태도, 친구관계, 교사관계의 영향력을 확인하는 것이다. 연구 대상자는 한국청소년정책연구원에서 실시한 「한국아동·청소년패널조사 2018 (KCYPS 2018)」에서 중1코호트의 제4차 조사(2021년)에 해당하는 고등 학생 1학년 응답자 2,265명을 최종 연구 대상자로 선정하였다. 진로적응 력의 잠재프로파일 분류와 예측 변인들의 영향력을 확인하기 위해서 SPSS 26.0과 JAMOVI 2.2.5를 활용하여 잠재프로파일분석과 다항로지스 틱회귀분석을 수행하였다. 연구결과에서는 ‘진로적응 매우미흡집단’, ‘진 로적응 미흡집단’, ‘진로적응 보통집단’, ‘진로적응 우수집단’ 총 4개의 잠재프로파일 집단으로 분류되었다. 또한, 양육태도와 교사관계는 모두 잠재프로파일 분류에 유의한 영향을 미치는 것으로 나타났다. 그러나, 친 구관계는 잠재프로파일 분류에 유의한 영향을 주지 않는 것으로 확인되 었다. 이러한 연구결과는 향후, 청소년들의 진로적응력을 강화할 수 있는 교육제도 수립 및 프로그램 개발에 도움이 될 수 있을 것이다.

PURPOSES : This study analyzes the estimated traffic volumes on roads and railways based on econometrics. METHODS : The accuracy of traffic forecasting was analyzed based on the average difference between predicted and actual values. This study distinguishes itself from existing literature by conducting a comparative analysis categorized by project type. In this study, econometric analyses, including bias and efficiency evaluation, were conducted for 308 projects in Korea. RESULTS : We conducted econometric analysis by dividing the data into project types. This study examines the accuracy of estimates in South Korea's road and railway projects concerning various factors, including project types (mobility-focused or accessibility-focused), implementing agencies, and the performance of preliminary feasibility studies. Notably, it identifies a tendency for overestimation, particularly in railway projects and mobility-focused road projects, such as expressways and national highways, as well as in projects executed by local governments. The mean percentage error (MPE) for the analyzed projects was -46.62%, indicating a significant overestimation bias with resulting inefficiencies. However, our analysis revealed that road projects, particularly those accompanied by preliminary feasibility studies and implemented by the central government, exhibited reduced bias and improved efficiency. The presence or absence of preliminary feasibility studies significantly influenced estimation bias. Interestingly, even when preliminary feasibility studies are conducted, the choice of the implementing agency remains a crucial factor affecting estimation bias. In addition, railway projects continue to demonstrate a notable overestimation bias, warranting further attention. CONCLUSIONS : Considering bias, efficiency, and MPE is advisable when forecasting traffic.

Before the 15th century, the main buildings of the residences of the ruling class in Seoul consisted of Momchae(身梗), Seocheong(西廳), and Naeru(內樓)‧Chimru(寢樓). Based on the equality of the relationship between husband and wife, the couple lived in the main building[Momchae] in the center of the mansion, but based on the individuality of the relationship between husband and wife, each had an area consisting of the same section within the building. Naeru‧Chimru was the two floors bedroom building became a common living space for the minister and wife, upstairs in summer, downstairs in winter. In preparation for large gatherings and important receptions, an open-structured West Hall(西廳) was located on the west side of the mansion. Momchae, Seocheong, and Naeru‧Chimru were the common building types and layouts of the residences of the highest ruling class, including high-ranking officials, until the reign of King Sejong. However, from around the time of King Seongjong, Seocheong and Chimru came to be regarded as privileged and luxurious buildings only allowed for the grand prince's residence. The layout of the bedroom, main building (including Wings), Outer Sarang[外舍廊], and Joyangru[朝陽樓] of Prince Bongrim's mansion built in the first half of the 17th century clearly shows the transitional period when the arrangement of chimru, main building, and western office was disrupted and the layout changed to the Inner main building(Anchae for wife) and Outer main building(Sarangchae for husband).

This study was conducted to examine the architectural characteristics of Hak-seong Lee Family's Geun-jae-gong Historic House located in Seok-cheon-ri, Ung-chon-myeon, Ulju-gun, Ulsan. The house is said to have been rebuilt in the early 20th century after it was built in the 18th century, and now there are nine buildings left, including the An-chae, Sa-rang-chae, Sa-dang, storehouses and etc. This house is a large-scale house that is difficult to find similar cases in near region. The division of areas on each building is clear, and it is evaluated that it retains the typical characteristics of the head family in the late Joseon Dynasty in terms of its overall size and layout. In addition, the current wooden structure, which is said to have been rebuilt in the early 20th century, shows the composition method and space utilization method of the 3-Dori type upper structure, which have become more diverse since the late Joseon Dynasty. This has not been dealt with in the previous survey, and should be considered in detail through this paper.

The purpose of this study is to construct a regional-sector-fishery-offshore and inshore fishery competitiveness index, examine the types and changes of competitiveness, and derive implications by processing data of the Survey on the Current Status of Offshore and Inshore Fishery from 2013 to 2020 for this study. The main results of this study can be summarized as follows. First, considering the competitiveness of offshore and inshore fishery by region and year, Jeonnam, Jeju, and Incheon were relatively competitive. Second, considering the competitiveness of inshore fishery by region and year, we found that Jeonnam, Chungnam, Jeonbuk, and Jeju were relatively competitive. Third, looking at the types of competitiveness based on the competitiveness index in the management sector of offshore and inshore fisheries by region and year, Ulsan, Jeonnam, and Gyeongbuk were relatively competitive between 2014 and 2020. Fourth, Jeonnam and Jeju were relatively competitive between 2014 and 2020 based on the competitiveness index in the fishing sector of offshore and inshore fisheries by region and year. Fifth, we found that Jeonnam, Jeju, and Chungnam were relatively strong in the competitiveness of offshore and inshore fishery, combining the offshore and inshore fishery indexes by region and year. The results of this study have some limitation on outlier treatment, grade assignment, and weight for aggregation, so research considering these needs to be done in the future. In conclusion, the results of this study which were derived objectively and scientifically in the era of the 4th industrial revolution, when evidence-based decision-making was becoming critical, are expected to help the central or local governments determine the priority of support projects or investments.

In this study, a conjoint analysis was conducted to derive a combination of fishing quota management system by fish species preferred by fishermen. In the analysis, detailed levels were set according to each attribute of the system. For analysis, this study conducted a design question survey for conjoint analysis on 303 fishermen engaged in fishing activities in the offshore and coastal sea. The Conjoint analysis was conducted on all fishermen, offshore fishermen and coastal fishermen. In addition, an analysis was conducted on TAC system participants and non-TAC system participants, and the targets were classified for comparison according to the characteristics of fishermen. Fishermen’s preference for the system confirmed for six attribute (“catching fish even if there is no fishing quota”, “how to allocate fishing quota”, “fishing quota management agency”, “upper limit of fishing quota,” “Possibility of Trading in the Fishing Quota”, and “Application of Other Regulations.”) and the detailed level of each attribute. As a result of the analysis of the importance of attributes, fishermen thought that “fishing quota management agency (24.1%)” was very important, and “catching fish even if there is no fishing quota (23.9%)” and “how to allocate fishing quotas (22.9%)” were also given some importance.

본 연구는 한국 여성의류소비자의 한국형아유르베다 성격유형과 의류 구매후기의 관계연구를 하는 것이 목적이며, 이러한 연구 목적을 위해 연구대상은 수도권 거주하는 20대 이상 설문 대상자 542명이었으며, 이 중 최종적으로 불성실한 응답을 제외한 519부를 본연구의 자료로 사용 하였다. SPSS 26프로그램을 통해 주요변수의 타당성, 신뢰성을 확보하 기 위하여 탐색적 요인분석, 인구학적 특성을 확인하기 위해 빈도분석, 성격유형에 따른 구매후기 점수의 차이를 확인하기 위해 세 집단 이상의 평균차이를 확인할 수 있는 일원배치분산분석(One-way ANOVA)을 실 시한 분석결과는 여성소비자의 한국형아유르베다 기본심리유형 중 하나 인 카파형(K)이 피타형(P)에 비해 구매후기를 중요하게 본다는 것을 알 수 있다. 이는 피타형(P)이 카파형(K)에 비해 구매후기를 중시하는 경향 이 낮은 이유는 자기주장이 강하고 주도적이며, 강한신념을 지니고 믿음 이 확고한 성격을 갖고 있는 것과 관계가 있음을 확인할 수 있다. 연령 을 구분하여 분석한 결과, 20~30대에서 유의한 차이가 나타났으며, 사후 검정 결과 피타형(P)의 평균보다 카파형(K)의 평균이 높은 것으로 확인되 었고 다중회귀분석을 통해서도 유사한 결과가 도출되었다. 이는 기성세 대에 비해 20~30대에서 구매후기를 중요시하는 경향은 모바일을 사용한 온라인, 디지털 환경에 익숙하기 때문이라 분석된다. 따라서 본 연구는 여성소비자의 성격유형과 구매결정후기 관계를 분석함으로써 마케팅 및 경영적 기초자료로 활용할 수 있을 것으로 사료된다.

The objective of this study was to explore how different types of rewards affect customers’ inclinations to engage in environmental activities promoted through restaurant social media platforms. In addition, we investigated the potential moderating role of customer level of participation within the social media community. A total of 202 valid responses obtained by distributing a self-administered survey among restaurant patrons were subjected to hierarchical regression analysis to examine relationships between variables. The findings underscored the significant influence of economic and social rewards on shaping customer intent to participate in environmental initiatives promoted within restaurant social media communities. Furthermore, the study revealed that the extent of customer participation within the social media community moderated the relationship between rewards and their likelihood to partake in environmentally conscious behaviors. These results have meaningful implications for restaurant managers seeking to promote environmental initiatives effectively through social media platforms and within their establishments.

1996년 고성산불지역의 복원유형별 식생구조와 종다양도 변화를 파악하여 생태적 관점에서 복원의 효과를 정략적으로 평가하고자 자연복원지와 인공복원지로 구분한 영구조사지를 대상으로 매목조사와 군집분류를 수행하였다. 조사구 26개소를 대상으로 이원지표종분석(TWINSPAN)과 DCA분석을 통해 분류한 결과, 군집 I (신갈나무-굴참나무 군집), 군집 II (소나무군집) 2개의 군집으로 분류되었다. 군집 별 상대우점치 분석 결과, 군집 I은 굴참나무와 신갈나무가 우세한 가운데 졸참나무의 출현으로 참나무류 간의 경쟁이 예상된다. 군집 II는 소나무가 우점하는 가운데 잣나무가 출현하는 군집으로 소나무 군집이 유지될 것이나 향후 아교목층의 참나무류와의 경쟁이 예상된다. 군집 간 유사도지수는 32.31%로 나타났다. 종다양도지수는 군집Ⅱ에서 1.3940으로 군집Ⅰ의 1.0768보다 높은 것으로 나타났다. 자연복원지는 활엽수 중심으로 맹아 재생이 일어나 군집 I과 같은 참나무림으로 천이가 진행되었다. 인공복원지는 지속적인 관리로 인해 개체수는 줄었으나 생육공간 확보로 자연복원지보다 원활한 직경생장을 보이며 초기 식재종 중심의 군집으로 천이가 진행되고 있음을 확인하였다.

PURPOSES : The primary objective of this study is to analyze the relationship between the factors that affect traffic incident duration in the mainline, tunnel, and ramp segments of an expressway. In addition, this study derived the most suitable statistical prediction model based on various incident duration distributions. METHODS : South Korean expressway crash data for 11 years, from 2011 to 2021, were analyzed. The incident durations on the mainline, tunnel, and ramp segments were selected using the accelerated failure time model, which is a parametric survival analysis approach. RESULTS : The mainline segment showed that the incident duration increased during accidents, including guard pipe collisions, multivehicle collisions, and snowfall. In particular, collisions in a tunnel with shoulder facilities increase the incident duration, while decreasing the time in the ramp segment. CONCLUSIONS : The incident duration model for each segment type yielded the most accurate results when applying a log-logistic distribution.

인간 활동으로 광범위한 자연 생태계 변화로 지난 몇 세기 동안 전 세계적으로 생물다양성이 심각하게 위협받고 있다. 생태계의 변화 양상을 파악하는 것은 생물다양성 위협을 파악하고 관리하는 데 필수적이다. 이러한 필요성에 따라 IUCN 의회는 2019년에 생태계의 기능과 유형을 고려한 IUCN Global Ecosystem Typology(GET)를 구성했다. IUCN은 10개의 생태계 군계, 108개의 생태기능별 토지 유형(EFG; Ecological Functional Group)을 전 지구적 범위에서 지도로 제공하고 있다. IUCN GET 생태계의 유형 분류에 따르면 국내 생태계는 Realm (1수준)이 8개, Biome (2수준)이 18개, Group (3수준)은 41개 유형으로 분류된다. IUCN이 제공하는 GET의 경우 전 세계 규모로 제작되었기 때문에 해상도가 낮고 실질적인 토지 현황과 일치하지 않는 경우가 많다. 본 연구는 토지피복지도를 활용하여 국내 IUCN GET 유형 분류의 정확도를 높이고 실질적인 현황 을 반영한 지도를 제작하고자 했다. 이를 위해 ① IUCN GET에서 제공하는 국내 GET 데이터 체계를 검토하고, ② 이를 국내 현황과 비교 분석하였다. 이 과정을 통해 GET의 한계와 활용 가능성을 평가하고 ③ 이후 국가자료를 최대 한 활용하여 국내 현황을 반영한 국내 GET 유형 분류를 수행하였다. 본 연구는 토지피복지도와 기존 국가자료를 최대한 활용하여 국내 GET를 총 25개 유형으로 분류했다(Terrestrial Realm :9, Freshwater: 9 Marine-Terrestrial:5, Terrestrial-Freshwater :1, Marine-Freshwater-Terrestrial:1). 기존 지도와 비교했을 때 수정된 국내 GET의 경우 ‘F3.2 Constructed lacustrine wetlands’, ‘F3.3 Rice paddies’, ‘F3.4 Freshwater aquafarms’, ‘T7.3 Plantations’가 면 적이 가장 많이 축소되었다. 온대 산림(T2.2)의 면적이 가장 많이 늘어났고, ‘MFT1.3 Coastal saltmarshes and reedbeds’, ‘F2.2 Small permanent freshwater lakes’등 3개 유형 또한 수정 후 GET 면적이 증가했다. 해당 과정을 통해 기존 GET에서 모든 EFG의 합이 국토 면적의 8.33배를 차지하던 기존의 지도를, 토지피복지도를 활용하여 총합 이 국토 면적의 1.22 배가 되도록 수정하였다. 이를 통해 유형별 차이가 작고 정확성이 떨어진 기존의 EFG가 본 연구를 통해 개선 및 수정되었음을 확인하였다. 본 연구는 현장 요건을 반영한 데이터를 최대한 활용하여 GET 기준 에 상응하는 한국의 GET 지도를 제작한 것에 그 의의가 있다.

The compositions of ethnic groups in Macau vary with time. Prior to the opening of the port, the majority of the residents in Macau were Chinese people, including those living on land and at sea. After the port was opened, with the increase of Portugal businessmen and missionaries, the population was divided into Chinese people and foreigners (so-called ‘Yiren’ or 夷人in Chinese). Chinese people living on land were mainly of Hakka, Fujian, and Cantonese descent. Those living at sea were referred to as ‘Tanka People’ (named ‘Danmin’ or 蜑民in Chinese). They lived on floating boats for their entire lives and were similar to the ‘drifters’ in Japan. Since modern times, many refugees from mainland China and Southeast Asia flooded into Macau due to warfare. The development of industrialization required a larger number of laborers, and some ‘coolies’ entered Macau in legal or illegal ways, making it a multi-ethnic city. However, the Tanka people were not considered a minority ethnic group under the national ethnic policy of 56 ethnic groups since they did not have an exclusive language and shared dialects in different regions. As the ports inhabited by Tanka people gradually restored foreign trade, the boats and stilt houses used by Tanka people were dismantled to expand the infrastructure area of the ports. Many Tanka people began to live on land and marry people on land, leading to the disappearance of the Tanka group in Macau. The fishing boats and stilt houses used by Tanka people have also disappeared, with only a few remaining in areas such as Pearl River Delta and Hong Kong. This paper examines the natural and social environment of Tanka people in Macau from the Ming and Qing dynasties to the Republic of China, as well as the adaptive changes they adopted for the aforementioned environment in terms of living space and architectural type, on the basis of summarizing the historical activities of Tanka people. Finally, this study provides a layout plan and interior structure of the most commonly used boat for Tanka people from the Ming and Qing dynasties to the Republic of China, with the use of CAD and other technical software, along with reference to written historical documentation, and provides a case study for further research on the architectural history of Macau's inner harbor cities, from anthropological and folklore perspectives.

This study aimed to categorize consumers using super app functional characteristics to identify demographic differences, and analyze shopping orientations by consumer type. This data can be used by fashion and beauty companies for product planning and marketing strategies. To categorize super app consumers, data were analyzed with SPSS v.26.0 software using frequency, factor, reliability K-mean cluster, and distributed analyses, one-way-ANOVAs, and Scheffe verification. Cross-analysis was conducted to correlate super app consumer types with demographic characteristics. One-way-ANOVAs and Scheffe verification were used to analyze the differences in shopping preferences between super app consumer groups. As a result of our analyses, super app consumers were classified into four types: the ration type, the low-use type, the multifunction type, and the habit type. There were statistically significant differences between these types in age, occupation, marital status, average monthly household income, and shopping impact factors. Five super app user shopping orientations were identified: brand pursuit, pleasure pursuit, trend pursuit, risk perception, and economic orientation. The differences in the preferred orientation between super app consumer types were found to be statistically significant. The majority of respondents were multifunction type consumers. This group used the super app most frequently and effectively. They also demonstrated the highest scores for all five of the shopping orientations. The classification of consumer types in this study will allow the fashion and beauty industries to utilize super apps for more targeted product design and marketing.
