We propose a deep learning-based method that can estimate an appropriate lighting of both indoor and outdoor images. The method consists of two networks: Crop-to-PanoLDR network and LDR-to-HDR network. The Crop-to-PanoLDR network predicts a low dynamic range (LDR) environment map from a single partially observed normal field of view image, and the LDR-to-HDR network transforms the predicted LDR image into a high dynamic range (HDR) environment map which includes the high intensity light information. The HDR environment map generated through this process is applied when rendering virtual objects in the given image. The direction of the estimated light along with ambient light illuminating the virtual object is examined to verify the effectiveness of the proposed method. For this, the results from our method are compared with those from the methods that consider either indoor images or outdoor images only. In addition, the effect of the loss function, which plays the role of classifying images into indoor or outdoor was tested and verified. Finally, a user test was conducted to compare the quality of the environment map created in this study with those created by existing research.

This study investigates the buying behavior pertaining to Japanese brands according to the degree of patriotism of consumers in their 20s. A survey of 235 university students was conducted; the survey questioned the basic purchasing attitudes of consumers in their 20s regarding outerwear and underwear and then surveyed the purchasing attitudes regarding U brand's (representative Japanese brand) outerwear and underwear. To detect the correlation between patriotism and U brand purchases, this study asked questions about patriotism and investigated basic personal information. The research results were as follows. First, there was a significant difference in consumer's purchasing attitude toward outerwear and underwear. When of consumers who are in their 20s purchase outerwear, its design was the most important factor, whereas when purchasing underwear, functionality was the most crucial factor. Second, it was confirmed that consumer's attitudes toward U brand's outerwear and underwear differed. Although the evaluation of U brand's outerwear design was not positive, the consumer tended to be satisfied with the price. U brand's score concerning the functionality of underwear products received a slightly positive response. Third, a total of 235 respondents were divided into a high- and low-patriotism-group based on questions about patriotism. There were significant differences in their attitudes toward clothing and consumer's purchasing behavior at U brand. Highly patriotic consumers thought negatively about U brand outerwear products in terms of price and product quality than low patriotic consumers; however, there was no significant difference only regarding design evaluation. For underwear products, low patriotic consumers were more positive about the price, design, and functionality of U brand products than high patriotic consumers.

VARTM (Vacuum-assisted resin transfer molding) process is a low-cost process technology and affiliated with OoA (Out of Autoclave). Besides, it has been widely used in various fields. However, because of its lower quality than the autoclave process, it isn't easy to apply the VARTM process to the aerospace industry, which requires high reliability. The main problem of the VARTM process is the loss of mechanical properties due to the low fiber volume fraction and high void content in comparison to the autoclave. Therefore, many researchers have studied to reduce void and increase fiber volume fraction. This study examines whether the method of controlling atmospheric pressure could increase the fiber volume fraction and reduce void during the resin impregnation process. Reliability evaluation was confirmed by compressive strength test, fiber volume fraction analysis, and optical microscopy. As a result, it was confirmed that increasing the atmospheric pressure step by step in the VARTM process of impregnating the preform with resin effectively increases the fiber volume fraction and reduces void.

Objectives: This study was performed to investigate the level of participation in and satisfaction with training courses at job training institutions and to improve participation and satisfaction through changes in the training method for industrial ventilation subjects. Methods: The results were analyzed for the mean and standard deviation by t-test and ANOVA, (p=0.05). Participation rates were examined for three courses: specialization, job training, and supervisory. The participation inthe education was 428 people, and the result of satisfaction with the change of education method was 878 people. Satisfaction was investigated for the specialized curriculum and job training curriculum,but not the supervisor curriculum. The satisfaction results for six items(contents, quality, skill, level, degree of understanding, degree of practical) were analyzed according to the change in the training medium and the method among people in one occupational ventilation subject. Results: The participation rate was similar in the job training and specialized training courses, but the lowest rate was in supervisory courses(p=0.05). In general, there was the lowest participation on the first day of education, and the participation rate improved after the second day. Satisfaction with the course was high for the specialized education course with a number of practical education assignments(p=0.278). The satisfaction level for the teaching method in the industrial ventilation subjects was high in a mixed group which combined lecture and practice. The industrial ventilation course in the basic job training course showed a difference between lecture and mixed education(p=0.111), but there was no significant difference. However, the industrial ventilation course in the advance job training course showed a clear difference between lecture and the mixed education(p=0.036). Conclusions: Therefore, the first day of training should start in the afternoon so that more trainees can participate, and it is recommended to assign important subjects after two days. In addition, it is suggested that job competency-enhancing education utilize various educational methods and media.

Purpose - The purpose of this study is to classify and analyze existing studies from various angles through systematic literature review of how human resources development has been researched in the domestic franchise business. These studies are intended to suggest the direction in which human resource development research should be conducted in the future in the franchise business. Research design, data, and methodology - This study is based on systematic literature review methodology. It has gone through the process of subject language setting, literature search routing, search term selection, literature selection, literature classification and literature analysis. The systematic literature review identified 59 peer-reviewed dissertations and scientific journal publications on the subject of HRD in Korea franchise business. Result - This study analyzed by research methods, research industries, research population and dependent variable using the systematic review process. The literature studied in the 2000s mainly led to research on education and training of franchise employees in beauty franchise business. In the literature studied since 2010, human resources development was mainly studied in the supervisor in the restaurant franchise business, and in the study of competence rather than education and training. According to the research methods, statistical methods were mostly relatively simple, such as t-test or one-way distribution analysis until the 2000s, and after 2010, in-depth and structural studies using multiple return analysis, structural method analysis, path analysis, multi-dimensional scale analysis, AHP, etc were conducted. When classified by study dependant, early research until the 2000s focused on the study of education and training, which is an independent variable, on the satisfaction of education programs, job satisfaction, and immersion. On the other hand, studies conducted since 2010 have produced more complex results using various medium variants, and those related to management performance and relationship performance have been mainly studied, rather than the satisfaction of the education itself. Conclusions - While the domestic franchise business is expanding in terms of quantity, such as the number of franchises and franchises, the development in terms of quality for the joint growth of franchises and franchisees is still lacking. In order for the franchisee to continue to grow with each other, the franchisee must identify and develop their current performance or expected capabilities through capacity modeling at various targets and levels.

BACKGROUND/OBJECTIVES: This study aimed to develop healthy, appetizing high-protein snacks with enhanced isolated soy protein for diabetic patients and determine the blood glucose and insulin response after being consumed by these patients. MATERIALS/METHODS: Thirty adult patients aged between 30 and 75 years, with a ≤ 10-year history of type 2 diabetes and hemoglobin A1c of < 7.5%, were enrolled in this study. They made 3 clinical visits at one-week intervals. The control group consumed 50 g carbohydrates (white bread), whereas the test groups consumed high-protein grain (HP_G) or high-protein chocolate (HP_C) after an 8-hrs fast. Blood (2 ㎤) was drawn at 15, 30, 45, 60, 90, and 120 min before and after consumption to analyze the blood glucose and insulin concentrations. RESULTS: Compared to the commercial snacks, the developed high-protein snacks had below-average calorie, carbohydrate, and fat content and a 2.5-fold higher protein content. In diabetic patients who consumed these snacks, the postprandial blood glucose increased between 15 min and 2 h after consumption, which was significantly slower than the time taken for the blood glucose to increase in the patients who consumed the control food product (P < 0.001). Insulin secretion was significantly lower at 45 min after consumption (P < 0.05), showing that the high-protein snacks did not increase the blood glucose levels rapidly. The incremental area under the curve (iAUC), which indicated the degree of blood sugar and insulin elevation after food intake, was higher in the control group than the groups given the 2 developed snacks (P < 0.001), and there was no significant difference in insulin secretion. CONCLUSIONS: The results of the postprandial blood glucose and insulin response suggest that high-protein snacks are potential convenient sources of high-quality protein and serve as a healthier alternative for patients with type 2 diabetes, who may have limited snack product choices. Such snacks may also provide balanced nutrition to pre-diabetic and obese individuals.

This study investigated the acoustic characteristics of sustained vowel /a/ and sentence utterance produced by patients with muscle tension dysphonia (MTD) using cepstrum-based acoustic variables. 36 women diagnosed with MTD and the same number of women with normal voice participated in the study and the data were recorded and measured by ADSVTM. The results demonstrated that cepstral peak prominence (CPP) and CPP_F0 among all of the variables were statistically significantly lower than those of control group. When it comes to the GRBAS scale, overall severity (G) was most prominent, and roughness (R), breathiness (B), and strain (S) indices followed in order in the voice quality of MTD patients. As these characteristics increased, a statistically significant negative correlation was observed in CPP. We tried to classify MTD and control group using CPP and CPP_F0 variables. As a result of statistic modeling with a Random Forest machine learning algorithm, much higher classification accuracy (100% in training data and 83.3% in test data) was found in the sentence reading task, with CPP being proved to be playing a more crucial role in both vowel and sentence reading tasks.

A new cultivar of oak mushroom 'Dadam' was bred from monokaryotic strains of 'GMLE36062-4' and 'GMLE36288-34'. The optimum temperature for mycelial growth of the new cultivar 'Dadam' on potato dextrose agar was 19-22℃. Total cultivation period of the new cultivar, from innoculation to its first harvest, was 135-139 days, similar to that of the control cultivar 'Hwadam'. The pileus color and stipe thickness of the new cultivar were darker and thinner than those of 'Hwadam'. Total yield of 'Dadam' was 621 g per 3 kg substrate, and is higher than that of 'Hwadam' (371 g). In farmhouse field test, it showed that the period of mycelial growth, browning, and fruiting body formation were the same as those of the control cultivar L808. The number of available fruiting bodies of 'Dadam' was 15, and is lower than that of the control (47), therefore, it was possible to save workforce in thinning. The total yield for 2 flush was 480 g for 'Dadam', similar to the 473 g of the control cultivar.

In this study, a series of processes for evaluating the effective protection against barriers that should be equipped in institutions that perform reliability tests on high-risk ammunition, such as high-explosive ammunition, were introduced. The impact that high-explosive bombs can have on personnel includes damage to the eardrum and lungs caused by explosion overpressure and penetrating wounds that can be received by fragments generated simultaneously with the explosion. Therefore, a high-explosive with COMP B explosives as its contents were set up, and an explosion protection theory investigation to calculate the degree of damage, numerical calculations and simulations were performed to verify the protection power. A numerical calculation revealed the maximum explosion overpressure on the protective wall when the high-explosive exploded and the penetration force of the fragment against a 50 mm-thick protective wall to be 77.74 kPa and 41.34 mm, respectively. In the simulation verification using AUTODYN, the maximum explosion overpressures affecting the firewall and personnel were 56.68 kPa and 18.175 kPa, respectively, and the penetration of fragments was 35.56 mm. This figure is lower than the human damage limit, and it was judged that the protective power of the barrier would be effective.

Brownies containing whey powder (WP) with different levels of substitutions for wheat flour (0, 10, 20, 30, and 40% substitution for WP 0, WP 10, WP 20, WP 30, and WP 40, respectively) were prepared, and their properties were compared. Regarding appearance, the collapse of the sample surface noticeably started from WP 30. The moisture content was higher in samples containing WP than in the control (WP 0), and the weight of the brownie increased with WP content. As the WP amount increased, both the total and specific volumes of the brownies decreased. Regarding texture, a higher amount of WP resulted in a decrease in hardness, whereas adhesiveness increased significantly. The antioxidant activity also increased with increasing WP amount (from 35.28 to 51.47%). Regarding sensory characteristics, 20 or 30% WP in brownies increased mouth-feel properties, taste, and overall preference. Based on the above results, WP could improve the quality of brownies, and a substitution level of 20% could be the most appropriate.
