Objectives: The purpose of this study was to examine the effects of the types of nutrition labeling on the processing fluency, health evaluation and purchase intentions of home meal replacements. Methods: This online experimental study was conducted from December 29 to 31, 2019 and included 134 participants. The research design was 2 (Objective nutrition labeling: present vs. absent) × 2 (Evaluative nutrition labeling: present vs. absent) and each participant was randomly assigned to one of four groups. As stimuli, five types of ready-to-heat foods sold in the market were used. Results: Processing fluency (4.91 points) and purchase intention (4.13 points) were significantly high when both evaluative nutrition labeling and objective nutrition labeling were presented, and healthfulness evaluation (4.47 points) was significantly high when only evaluative nutrition labeling was presented. All three variables were measured to be high when evaluative nutrition labeling was presented. The evaluative nutrition labeling that visually represented nutritional values was found to be more effective for processing fluency, healthfulness evaluation, and purchase intention than the objective nutrition labeling representing the nutritional value of the product in numbers and proportions. Conclusions: These results show that it is necessary to develop various types of evaluative nutrition labeling to enable consumers to choose and purchase healthful home meal replacements. Also, consumer education and public campaigns are needed to encourage consumers to select healthier home-cooked meals using nutrition labeling.

Due to hazardous working environments at complex, unstructured, and dynamic construction sites, workers frequently face potential safety and health risks throughout the construction process. In this regard, addressing safety challenges remains one of the top priorities. Construction workers' ability to identify and assess risks is acquired through training, which is one of the primary key factors to determine their safety and wellbeing in hazardous working environments. As such, safety managers constantly focus on the effectiveness of the training materials provided to the workers. However, the construction workers are considerably at greater risk of injuries and fatalities compared to the workers in other industries. In this regard, further studies are required to build up a body of knowledge on the conventional safety training approaches as well as their evaluation techniques in order to boost up the adoption by the practitioners in a widespread manner. This paper provides a systematic review of the current safety training approaches and the various techniques for measuring their effectiveness. The attributes of the current safety training methods for construction workers and their evaluation techniques are identified and analyzed. Results indicated that: 1) immersive environment-based training methods are effective than the traditional safety training methods; 2) this effectiveness can be empirically supported by evaluation strategies, but the current techniques are subjective, intrusive, and error-prone. This research offers fresh opportunities to investigate the training strategies by objectively monitoring the physiological responses of construction crews. The results of this study can be used by researchers and practitioners to identify and determine optimal safety training programs that could potentially become ubiquitous in the construction industry.

Background: Recently, the single-step genomic best linear unbiased prediction (ssGBLUP) method, which incorporates not only genomic information but also phenotypic information of pedigree, is under study. In this study, we performed a ssGBLUP analysis on a commercial Hanwoo population using phenotypic, genotypic, and pedigree data. Methods: The test population comprised Hanwoo 1,740 heads raised in four regions of Korea, while the reference population used Hanwoo 18,499 heads raised across the country and two-generation pedigree data. Analysis was performed using genotype data generated by the Hanwoo 50 K SNP beadchip. Results: The mean Genome estimated breeding values (GEBVs) estimated using the ssGBLUP methods for carcass weight (CWT), eye muscle area (EMA), back fat thickness (BFT), and marbling score (MS) were 7.348, 1.515, -0.355, and 0.040, respectively, while the accuracy of each trait was 0.749, 0.733, 0.769, and 0.768, respectively. When the correlation analysis between the GEBVs as a result of this study and the actual slaughter performance was confirmed, CWT, EMA, BFT, and MS were reported to be 0.519, 0.435, 0.444, and 0.543, respectively. Conclusions: Our results suggest that the ssGBLUP method enables a more accurate evaluation because it conducts a genetic evaluation of an individual using not only genotype information but also phenotypic information of the pedigree. Individual evaluation using the ssGBLUP method is considered effective for enhancing the genetic ability of farms and enabling accurate and rapid improvements. It is considered that if more pedigree information of reference population is collected for analysis, genetic ability can be evaluated more accurately.

The purpose of this study is to provide basic data on effective urban regeneration projects and development directions for improving the quality of life of local residents by analyzing urban regeneration projects that have been carried out so far according to evaluation items on public design characteristics. The research method was divided into literature review and case study. The research results are as follows. First, through analysis of previous research, seven evaluation items for public design characteristics were derived: publicness, accessibility, regional identity, aesthetics, communication, functionality, and sustainability. The research subjects were four urban regeneration project cases carried out across the country. Second, among the seven evaluation items for public design characteristics, publicness was all highly applied, but the other six items were applied differently in each case. Third, to increase sustainability, we must use eco-friendly materials and consider sustainable maintenance methods, functionality must be strengthened in terms of functionality and comfort of public facilities and public spaces, and communicability must be improved for local tourists. We actively look for ways to communicate with the public, accessibility involves incorporating more universal design, aesthetics focuses on adding beauty to spaces and facilities, and regional identity focuses on the unique and unique characteristics of each region. We suggest finding a theme and actively using it in urban regeneration projects. Lastly, for an urban regeneration project to be successful, it is necessary to effectively apply not only publicness but also accessibility, local identity, aesthetics, communication, functionality, and sustainability. In the future, public design characteristics should be more actively applied and considered in urban regeneration projects.

National forests have been assumed to do a leading role in carbon sequestration and creating forest resources since society demanded it due to climate change. Therefore, it is needed to check whether a national forest management plan and its evaluation are implemented effectively. As an effective planning and management is to be ensured on the basis of proper evaluation system, this research suggests to improve the evaluation system by analyzing it theoretically. Improvements for national forest management plan and its evaluation are as follows: (1) adjusting evaluation goal and time; (2) giving weighting to each work when planning; (3) writing details of change in planning and its grounds; (4) using the national forest management information systems to integrate these evaluation methods and result. Since to predict future changes in forests and achieve sustainable forest management begins at the reliable evaluation for overall process of the implemented project, the significance of this study is in proposing the improvement of evaluation system for national forest.

This study, centering on public enterprises, has been conducted from 4 different perspectives such as grasping the effects that the factor precedent of the multi-rater feedback affects on the usefulness of evaluation and the effects that the usefulness of evaluation affects on the organizational achievement, checking on whether there is any discrepancy among the effects affecting on the usefulness of evaluation in accordance with the degree of advance training on the evaluation system, and being what kind of effects the usefulness of valuation that the appraised eventually understand affects on the organizational achievement. As result of the study, the factor precedent that are confidence of the appraisers and the support from CEO reasonably affected on the usefulness of evaluation, but the standard referred to evaluation was not reasonable. It became resultantly clear that the confidence of the appraisers held the effect of control from the verification of whether there is the effect of control between the factor precedent and the usefulness of evaluation in accordance with the degree of advance training. However, it turned out that the standard referred to evaluation and the support from CEO held no effect of control. As result, It was possible to confirm that the usefulness of evaluation in this study affects directly or indirectly to the organizational achievement such as organizational immersion, job satisfaction, self development opportunity, and organizational revitalization as influenced by the prior factors, and the advance training was partially effective on the adjusting effect.

The effective unsaturated hydraulic conductivity in stratified soils is evaluated using a three-dimensional stochastic approach. Because of the disparity of the correlation scales in a stratified soil, the general stochastic equations are simplified. This allows analytical evaluation of generic expressions for the effective hydraulic conductivities. Simple asymptotic expressions, valid at particular ranges(wetting front, drying condition, wetting condition) of the mean flow characteristics, are also derived. An example of applying the derived theoretical result to a imaginaryl clay soil is presented. It reveals found that the effective unsaturated hydraulic conductivity showed large-scale hysteresis. Such large-scale hysteresis was produced by the spatial variability of hydraulic soil properties rather than hysteresis of the local parameters. In addition the results show that the effective hydraulic conductivities were larger in the case of accommodating heterogeneity of soil preperties rather than neglecting heterogeneity of soil properties.

Pollutant unit load (unit-load) reported by Ministry of Environment (MOE) in 1995 has been a useful method for watershed management and environmental policy decision. The unit-load has been estimated using effective rainfall ratio method. However, reliability of unit-load determined by the method has been criticized especially for paddy field and upland conditions. In this paper the unit-load of paddy field estimated by effective rainfall ratio method was compared with continuous monitoring data. Annual loads was simulated by the method choosing 5~6 storm events randomly from whole events collected. Probability distribution of difference between results by the method and measured data was investigated. The results showed that unit-load derived by the method was generally lesser than measured unit-load and showed wide variations. Therefore, unit-load estimation of paddy fields by effective rainfall ratio method need caution.

Oldenlandiae Herba has been used for the prevention or treatment of cancer in oriental medicine for years. Experimentally its antitumor activity was reported. However, in order to develop new Korean original plants. we tried to study the antitumor activity of Chinese and Korean origin Oldenlandiae Herba. We first evaluated the cytotoxicity of Oldenlandiae Herba originated from China and Korea on HT1080, U937 and SK-mel tumor cells. MeOH extract of Chinese Oldelandiae Herba was more effective than MeOH extract of Korean Oldenlandiae Herba. Approixmately IC50 of two species of Oldelandiae Herba was 380-450 ug/ml. For evaluation of antiangiogenic activity, proliferation assay with HUVECs(Human umblical vein endothelial cells) was done with three samples. Chinese Herba and Korean Herba and root. Korean root and herba was more effective than Chinese Herba. Thus, we found Korean Oldenlandiae was more effective on angigenic activity than Chiness Oldenlandiae. In an anlytical study on effective compounds from Oldenlandiae, the spot of ursolic acid was more marked by Korean Oldenlandiae than by Chinese Oldenlandiae. whereas the spot of asperuloside was more pronounced by Chinese Oldenlandiaethan by Korean Oldenlandiae by TLC analysis.

After the nuclear accident of the Fukushima Dai-ichi Nuclear Power Plants (FDNPPs) on 11 March 2011, a large amount of radioactive materials has been released into the atmosphere and the ocean. A compartment model is used to evaluate the circulation characteristics and the spatiotemporal concentration distributions of radionuclides in the ocean. In the comparison with observed concentrations of $^{137}Cs$ in seawater, calculated concentrations by the compartment model were well agreed with them. On the basis of these results, we performed evaluation of the effective dose and the cancer risk. In the early stage of the accident, the effective doses from ingestion of the seafood near the Fukushima region were much higher than 1 mSv which is the value of the annual effective dose limit to individual recommended by the International Commission on Radiological Protection (ICRP). However, the effective doses by ingestion of the seafood decreased below 1 mSv as distance from the FDNPPs increased and time passed. In addition, it was estimated that the cancer risks by intake of the contaminated marine products were less than natural occurrence probability of cancer. Consequently, it was inferred that the health risk due to the $^{137}Cs$ was low after since mid-term period of the accident.
