본 연구는 이탈리안 라이그라스(IRG)를 단파 및 혼파에 따라 건물수량의 차이를 비교 분석하여 이상기상 발생 시 적합한 품종을 추천하기 위하여 실시하였다. 천안의 평균온도와 천안의 30년 간 평균온도는 비슷한 경향이었으나, 11월과 3월은 이상기상으로 판단된다. IRG 품종은 Green Fram(GF, 극조생), Kowinearly(KE, 조생), Kowinmaster(KM, 중생), Hwasan 104(H104, 만생)로 단파 또는 혼파하였다. GF 출수 기준으로 수확 시 GF+H104의 건물수량이 유의적으로 가장 높게 나타났다(p<0.05). KE와 KM 출수기준으로 수확 시 KE 및 KE+KM의 건물수량이 유의적으로 높게 나타났다. H104 출수기준으로 수확 시 건물수량은 처리간에 유의적인 차이는 없었으나(p>0.05). KM이 16,763.1 kg/ha로 가장 높았다. IRG 수확시기의 건물수량을 비교하였을 때 KE, KM의 단파 및 혼파에서 가장 높았다. 최근 봄 가뭄 등 이상기상의 발생 빈도가 높아지고 있으므로 이상기상에 대비하기 위하여 조생 및 중생을 이용한 IRG 혼파재배가 필요한 것으로 판단된다.

Purpose - In franchise system, how to build the relationship between the franchisor and franchisee through influence strategy is very important, because it affects on the long-term orientation like recontract intentions. Thus, this study examines the effect of mandatory influence strategy on relationship satisfaction, relationship trust, and recontract intentions in the context of food-service franchise industry. This study suggests the guidelines on how franchisor uses their influence strategy on franchisee to maintain and increase the recontract intentions. Research design, data, and methodology - This study examines the structural relationship between mandatory influence strategy, relationship satisfaction, relationship trust, and recontract intentions from the franchisee's perspective. Mandatory influence strategy divide into three sub-dimensions such as request, legalistic plea, threat. In order to test the purposes of this study, research model and hypotheses were developed. Every constructs were measured by multiple items tested and developed in the previous research. Also, the constructs utilized in this research are measured using 7-point scales anchored by "1=strongly disagree" and 7=strongly agree". The data were collected from 496 owner and owner manager franchisees and were analyzed using SPSS 21.0 and Smart PLS 3.0. program. Analysis of frequency was conducted to identify the demographics and general characteristics of the survey subjects. In order to measure the reliability and validity of the measurement tools, confirmatory factor analysis and correlation analysis were conducted and structural model analysis was conducted to verify the proposed research model. Result - The results of this study are as follows. First, this research found that mandatory influence strategy is positively related to relationship satisfaction and relationship trust, but not to recontract intention directly. Second, this research also found that the full mediating role of relationship satisfaction and relationship trust between the mandatory influence strategy and recontract intention. Conclusions - The findings of this research indicate that franchisor should use properly mandatory influence strategy to improve recontract intentions through relationship satisfaction and relationship trust. Due to the nature of food-service franchise industry, which needs high relationship quality, franchisor must manage their franchisee using influence strategy in order to improve satisfaction and trust. If franchisee perceives higher relationship quality, they will show higher intention to recontract. At the end of this paper, limitations and future research directions were suggested.

Purpose - In recent years, research has been conducted on the conflict resolution strategies of the franchise headquarters and the franchisees, but there is a lack of research on how the power structure and cultural factors play a role in resolving conflicts. From this perspective, this study is to examine the structural relationship between franchisors' cultural orientation and relationship power, and conflict resolution strategies, relationship trust, and relationship performance using. The findings of this study suggest how franchise headquarters should establish long-term relationship with franchisees and share information. Research design, data, methodology - The data were collected from April 1 to April 15, 2013. Because this study examined franchise industries from the franchisee perspective, we contacted franchisee store owner and managers located in Seoul and Gyeonggi Province. Interviewers trained contacted a total of 200 franchisees, and 196 franchisees responded. Out of 196 respondents, 13 respondents were deleted due to missing information. Thus, a total of 183 franchisee were used for this study. he data were analyzed using frequency analysis, confirmatory factor analysis, correlation analysis, and structural equational modeling with SPSS 24.0 and Amos 23.0 statistical program. Results - The results showed that cooperation orientation and relational power of franchisor had significant effects on conflict resolution strategies. Cooperating, obliging, and compromising strategies of conflict resolution strategy had significant effects on relationship trust. Also, relationship trust had significant effect on relationship performance. Conclusions - This study shows that the franchise headquarters and the franchisees share necessary information for common purposes and that continuous two-way communications play an important role in resolving conflicts. In other words, the result of this study suggests that if the franchise headquarters and the franchisee actively consider the position of the other party and strive to achieve the goal, conflict resolution may be more successful. In order to do this, the franchise headquarters will have to consider how to build and maintain continuous communication with the franchisees, and continuous education is also needed so that employees can have a cooperative attitude. However, since the culture of these organizations is not made up of simple staff training and is not formed within a short time, the CEO of the franchisee headquarters should take the lead in establishing a cooperative culture with the merchants over the long term.

Steel-concrete composite box girder bridges are widely used in the construction of highway and railway bridges both domestically and abroad due to their advantages of being light weight and having a large spanning ability and very large torsional rigidity. Composite box girder bridges exhibit the effects of shear lag, restrained torsion, distortion and interface bidirectional slip under various loads during operation. As one of the most commonly used calculation tools in bridge engineering analysis, one-dimensional models offer the advantages of high calculation efficiency and strong stability. Currently, research on the one-dimensional model of composite beams mainly focuses on simulating interface longitudinal slip and the shear lag effect. There are relatively few studies on the one-dimensional model which can consider the effects of restrained torsion, distortion and interface transverse slip. Additionally, there are few studies on vehicle-bridge integrated systems where a one-dimensional model is used as a tool that only considers the calculations of natural frequency, mode and moving load conditions to study the dynamic response of composite beams. Some scholars have established a dynamic analysis model of a coupled composite beam bridge-train system, but where the composite beam is only simulated using a Euler beam or Timoshenko beam. As a result, it is impossible to comprehensively consider multiple complex force effects, such as shear lag, restrained torsion, distortion and interface bidirectional slip of composite beams. In this paper, a 27 DOF vehicle rigid body model is used to simulate train operation. A two-node 26 DOF finite beam element with composed box beams considering the effects of shear lag, restrained torsion, distortion and interface bidirectional slip is proposed. The dynamic analysis model of the coupled composite box girder bridge-train system is constructed based on the wheel-rail contact relationship of vertical close-fitting and lateral linear creeping slip. Furthermore, the accuracy of the dynamic analysis model is verified via the measured dynamic response data of a practical composite box girder bridge. Finally, the dynamic analysis model is applied in order to study the influence of various mechanical effects on the dynamic performance of the vehicle-bridge system.

Objectives To investigate the effectiveness of acupuncture in the treatment of post-disaster musculoskeletal pain by reviewing relevant clinical studies. Methods A systematic search was conducted across 10 electronic databases to identify relevant clinical studies on acupuncture treatment for post-disaster musculoskeletal pain until May 2023. The methodological quality was evaluated using the Cochrane Risk of Bias 2 and Risk of Bias Assessment tool for non-randomized studies tools. Results Six articles were analyzed, including two randomized controlled trials (RCTs), two before-after studies, one qualitative research, and one case series. Overall, acupuncture therapy showed some improvement in pain scale among musculoskeletal pain survivors. However, no significant improvement was observed in the Short-Form McGill Pain Questionnaire (SF-MPQ-2). Subgroup analysis of participants who completed at least four acupuncture sessions revealed a significant effect on the SFMPQ-2. Additionally, a significant improvement in 36-Item Short Form Survey (SF36P) was observed after 6 months of treatment, but the 2-month treatment period did not show statistically significant effects on SF-36P improvement. The evaluation of the methodological quality of the RCTs identified some concerns of bias. Conclusions The results suggest that acupuncture is effective in alleviating post-disaster musculoskeletal pain. However, considering the limited number of selected studies and the inclusion of subjective evaluation measures, caution should be exercised in interpreting the results. Further large-scale follow-up studies are needed to determine the optimal frequency and duration of acupuncture treatment. Well-designed controlled trials should be conducted to provide more robust evidence regarding the effectiveness of acupuncture for post-disaster musculoskeletal pain.

Background: The Korea Centers for Disease Control and Prevention (KCDC) has identified cases of people suspected of suffering lung disease potentially caused by chloromethylisothiazolinone/methylisothiazolinone (CMIT/MIT) used in humidifier disinfectants (HDs). The Korean Ministry of Environment (MoE) epidemiological investigation and toxicity test study found that HDs caused health damage such as asthma and lung disease. Objectives: The main purposes of this study were to classify the HD exposure rating and to analyze the exposure characteristics that affect exposure to CMIT/MIT HDs. Methods: The exposure characteristics and socio-demographic characteristics of victim participants using CMIT/MIT HDs were investigated through questionnaires. An inhalation no observed adverse effect level (NOAEL) for CMIT/MIT was produced based on inhalation toxicity values. Exposure ratings (class 1~class 2) were cross-tabulated with clinical ratings (acceptable~unacceptable). A correlation analysis was conducted with the main exposure characteristics that affect the exposure concentration of CMIT/MIT HDs. Results: The concentration in indoor air of CMIT/MIT was 8.75±25.40 ㎍/m³, and the exposure concentration was 2.30±6.29 ㎍/m³. The CMIT/MIT exposure rating of 67 participants with high exposures of not more than MOE 100 were evaluated as 14.5%, while the damage participants who matched the clinical rating made up 4.5%. The exposure concentration of CMIT/MIT showed a positive correlation with the daily usage amount and usage frequency, and a negative correlation with volume of the indoor environment. Conclusions: A new exposure rating could be suggested and calculated based on the MOE, and the factors affecting the exposure concentration could be identified.

The purpose of the study w3s to investigate the consumption pattern of the Korean traditional foods of the elementary schoolchildren living in urban and rural area. For the investigation, 373 fifth-grade elementary schoolchildren in Incheon and Gangwhado were surveyed by a questionnaire and the data were analyzed by the SPSS 10.0 program. As for the frequency to take the Korean traditional foods, bab and kimchi are taken almost everyday, and gug, jjigae, jorim, gui, namul are taken frequently. And juk, jeongol, jeon, sanjeog, jutgal, hangwa and umryo were shown to be taken occasionally. There were statistical differences in the frequencies of the Korean traditional food consumption by the residence and the gender. The students in urban area take hinbab, jabgokbab, hobakjuk deonjanggug, sangsunjorim, jangiorim more frequently than the students in rural area. The students in rural area take mandu, kuksoo, yeongunjorim and kongiorim more frequently than the students in urban area Female students take sangsunjorim, jangiorim, sangsungui, bulgogi, sangsunjeon, hobakjeon, sukchae, jutgal and oiji more frequently than male students. Most of the schoolchildren answered that in the future they would like to take the traditional foods more frequently than now. There was statistical difference by the gender. As for the food such as bibimbab, gug, jjigae, jeon, namul and jang-aji, female students responded to take more frequently than male students. The 39.1% of them responded that the taste is the point to be most improved in the future. But there was no statistical difference by gender and the residence In order to make the taste of traditional food more attractive to modem people, the 37.8% of them replied it does not need to change the traditional preparation method. However, similar percentage of the schoolchildren(35.7%) answered it is needed to change partly the traditional preparation method. As for the effect of traditional foods on health, the 68.4% of schoolchildren thought that the our traditional foods are healthier than western foods.
