Purpose: This study attempted to systematically review the programs of patients with post-traumatic stress disorder in South Korea over the past decade, identify specific methods and effects, and present program guidance guidelines through them. Research design, data and methodology: This study is a systematic literature review, and studies registered in the RISS, NDSL, DBpia, and KmBASE search databases from January 1, 2013 to August 31, 2023 were targeted. Keywords were 'post-traumatic stress disorder', 'program' or 'treatment'. A total of 2,324 documents were searched, and 237 duplicate papers were excluded. After that, the title and abstract were viewed, and 2,058 papers that did not meet the inclusion criteria and exclusion criteria were excluded. In addition, the full text was checked and the final 11 documents were analyzed excluding 18 documents. Results: Among the 11 literatures, 45.45% of randomized control studies and 54.54% of non-randomized control studies were found. As for gender, 41.18% of women, 28.64% of 30-39 years old, and 34.27% of trauma causes were industrial accidents. Programs for patients with post-traumatic stress disorder were classified into art therapy, cognitive behavior therapy, and mindfulness programs, and art therapy was the most used at 45.45%. The sessions of the program were widely applied at 45.45% for 10 sessions and 36.36% for 60 minutes per session. Conclusions: This study has a limitation in that it only analyzed domestic intervention programs within 10 years. However, this study is meaningful in that it is intended to present program guidance guidelines through reviewing domestic programs for post-traumatic stress patients. In the future, it is necessary to conduct research such as expanding the scope of literature review at home and abroad.

Vibration investigation of fluid-filled three layered cylindrical shells is studied here. A cylindrical shell is immersed in a fluid which is a non-viscous one. Shell motion equations are framed first order shell theory due to Love. These equations are partial differential equations which are usually solved by approximate technique. Robust and efficient techniques are favored to get precise results. Employment of the wave propagation approach procedure gives birth to the shell frequency equation. Use of acoustic wave equation is done to incorporate the sound pressure produced in a fluid. Hankel's functions of second kind designate the fluid influence. Mathematically the integral form of the Lagrange energy functional is converted into a set of three partial differential equations. It is also exhibited that the effect of frequencies is investigated by varying the different layers with constituent material. The coupled frequencies changes with these layers according to the material formation of fluid-filled FG-CSs. Throughout the computation, it is observed that the frequency behavior for the boundary conditions follow as; clamped-clamped (C-C), simply supported-simply supported (SS-SS) frequency curves are higher than that of clamped-simply (C-S) curves. Expressions for modal displacement functions, the three unknown functions are supposed in such way that the axial, circumferential and time variables are separated by the product method. Computer software MATLAB codes are used to solve the frequency equation for extracting vibrations of fluid-filled.

This study examined the influence of perceptions of food risk and food labeling on the purchase of labeled food items and the intention to pay higher prices for safe food. Data were obtained from the Korea Rural Economic Institute's Consumer Behavior Survey for Food 2020. The analysis focused on the responses of 6,355 consumers, all of whom were mainly responsible for food purchases. The analysis investigated the moderating effect of food risk perception on the relationship between food labeling perception and the purchase of labeled food. Regarding the purchase of labeled food, statistically significant effects were noted for gender, educational level, perception of food labeling, and perception of food risk; however, the interaction effect of perceptions of food labeling and food risk was not statistically significant. With regard to the intention to pay higher prices for safe food, except for age, statistically significant effects were observed for gender, educational level, food expenditure, perception of food labeling, and perception of food risk; moreover, the interaction effect of perceptions of food labeling and food risk was significant. The results indicate that consumers reporting low food labeling perception and low purchase of labeled food were most vulnerable regarding food safety; therefore, it is necessary to provide such consumers with food label provision methods and specified education programs.

This study aimed to investigate the effect of treating environmental purification insect larvae to pig manure on crude ash contents and ammonia production. The experiment set up consisted go two groups: 1 kg of each 3^rd instar TM (Tenebrio molitor) and 3^rd instar PBS (Protaetia brevitarsis seulensis) larvae in Experiment 1 or 3^rd and 4^th instar of HI (Hermetia illucens L.) larvae in Experiment 2 were treated with 5 kg of pig manure. In Experiment 1, the crude ash content was higher in TM larvae-treated pig manure at days 0 and 5 (p>0.05), but was similar to that in PBS larvae-treated pig manure over (p>0.05). Ammonia production was observed at day 0 of TM and PBS larvae-treated pig manure (p<0.05), but did not occur thereafter. For Experiment 2, there was significant difference in crude ash content of 3^th and 4^th instar HI larvae-treated pig manure on day 15. Additionally, ammonia production was found in 3^th and 4^th instar HI larvae-treated pig manure at days 0 and 5, but did not continue over time. In conclusion, treating TM, PBS and HI to pig manure changed the crude ash contents and reduced ammonia through the ability to decompose pig manure. Thus, environmental impact can be minimized using environmental purification insect larvae.

Purpose - The purpose of this study is to examine the gravity model commonly used for demand forecasting upon the implementation of new tourist facilities and analyze the main causation of forecasting errors to provide a suggestion on how to improve. Design/methodology/approach - This study first measured the errors in predicted values derived from past feasibility study reports by examining the cases of five national science museums. Next, to improve the predictive accuracy of the gravity model, the study identified the five most likely issues contributing to errors, applied modified values, and recalculated. The potential for improvement was then evaluated through a comparison of forecasting errors. Findings - First, among the five science museums with very similar characteristics, there was no clear indication of a decrease in the number of visitors to existing facilities due to the introduction of new facilities. Second, representing the attractiveness of tourist facilities using the facility size ratio can lead to significant prediction errors. Third, the impact of distance on demand can vary depending on the characteristics of the facility and the conditions of the area where the facility is located. Fourth, if the distance value is below 1, it is necessary to limit the range of that value to avoid having an excessively small value. Fifth, depending on the type of population data used, prediction results may vary, so it is necessary to use population data suitable for each latent market instead of simply using overall population data. Finally, if a clear trend is anticipated in a certain type of tourist behavior, incorporating this trend into the predicted values could help reduce prediction errors. Research implications or Originality - This study identified the key factors causing prediction errors by using national science museums as cases and proposed directions for improvement. Additionally, suggestions were made to apply the model more flexibly to enhance predictive accuracy. Since reducing prediction errors contributes to increased reliability of analytical results, the findings of this study are expected to contribute to policy decisions handled with more accurate information when running feasibility analyses.

This study compared the physicochemical properties of edible insect oils from silkworm (Bombyx mori) pupa (SP), sago palm weevil (Rhynchophorus ferrugineus) larva (PW), and bamboo caterpillar (Omphisa fuscidentalis; BC) to oils from chicken skin (CK), beef back fat (BF), pork back fat (PF), salmon belly (SB), sea bass belly (BB), coconut (C), and peanut (P). The fatty acid profiles and thermal behaviors (crystallization and melting) of the extracted oils were evaluated. PW and BC oils had more saturated fatty acids (SFAs) than CK, PF, SB, BB, and P oils. SP oil had equivalent SFA content to CK and BB oils. Insect oils exhibited similar monounsaturated fatty acid concentrations in all samples, except C oils. PW and BC oils exhibited a higher content of palmitoleic acid than the other oils. SP oils contained polyunsaturated fatty acids similar to those in SB and BB oils, which were higher than those in PW, BC, CK, BF, and PF oils. SP oil also exhibited the highest concentration of α-linolenic acid (C18:3 n-3). Arachidonic acid (0.01-0.02 g/100 g) in all insect oils was lower level compared to CK, BF, PF, SB, and BB oils. SP oil (0.03 g/100 g) exhibited a slightly higher level of eicosapentaenoic acid compared to PW (0.01 g/100 g) and BC (0.01 g/100 g) oils. The insect oils were liquid at ambient temperature, solid below -15℃, and required less energy (∆H_m-max) for melting than other samples. This study indicated that insects, particularly SP, could serve as an alternative source of fat to meet its growing demand.

Make-up culture has recently emerged as a major trend among adolescents, and their knowledge of this culture is acquired from their peers. Adolescence is a period in which peer relationships have a significant effect on individuals' behavior and self-esteem. Also, adolescents are conscious of others' evaluation because they only want to exhibit their ideal-self. They generally apply make-up for various reasons; pursuing ideal beauty, concealing their insecurities and improving their own self-esteem. The purpose of this study is to design and implement the MUSE(Make-Up & Self-Esteem) project, to reduce self-esteem disparity based on make-up status. Ten female adolescents(mean age=17.0 yrs, SD=1.49) participated in the MUSE project, in which the participants gradually reduced their make-up steps and posted feelings about this on SNS. Also, events were designed for the participants to enhance their interest and become more focused on themselves without make-up. Resultantly, it was obeserved that after the project, the gap between the particiapnts' self-esteem with and without make-up decreased. More specifically, there was no significant difference in self-esteem with make-up before and after participating in the project, but a significant increase was observed in self-esteem without make-up after the project. Although the participants were mostly satisfied with the project, individual interviews were conducted to obtain feedback regarding how the project could be improved. The participants suggested that future project could be developed within their own peer group and the term of the project could be extended so that the participants could become accustomed to daily make-up reducing steps.
