In a situation where worldwide free trade between countries has expanded recently, our country is being rapidly pushed FTA agreements with the financial developed countries such as United States, EU. According to the agreement, the user information of foreign financial companies in Korea is expected to be transfered overseas. In this paper, we need to define the scope and the definition about the transfer of information and analyze the relating domestic and foreign laws preparing for Cross Border Financial Information Transfer. Also, we review the expected issues about the transfer of information divided into institutional and technical sectors and arc presented the policy implication such as differentiation of regulatory information, enactment and amendment of Personal Information Protection Law(Draft) and related regulations, ensuring the safety of financial companies, raise the standard guidelines of the transfer of information. We refers to the needs for policy formulation to differentiate our privacy information from financial information to protect the privacy of users. The proposed countermeasures in this paper is expected to be helpful the measures to prepare for other institutions such as banks and supervisory authorities prepare for the future Cross Border Financial Information Transfer according to PTA.
This study aimed to define the diagnostic criteria for cervicogenic headache and propose an efficient method of clinical evaluation and physical therapy. Fifteen patients with cervicogenic headache and 15 healthy individuals were recruited and categorized into the test group and the control group, respectively. The groups were compared in terms of muscle characteristics, muscle activity and posture, and the intervariable correlations were analyzed for the test group. A significant between-group difference was found in the stiffness of the suboccipital muscle and the tone and stiffness of the upper trapezius muscle (p<.001). In posture comparison, a significant difference was noted in neck tilt angle and the T1 slope angle (p<.05). The activity of the sternocleidomastoid muscle was also significantly different between the groups (p<.001). When the correlations among the muscle characteristics, the posture, and the activity of the sternocleidomastoid muscle were analyzed for the test group, a positive correlation was found between the tone and the stiffness of the suboccipital muscle (p<.001) and between the tone and the stiffness of the upper trapezius muscle (p<.001). The findings of this study suggest a more efficient approach for the assessment and treatment of cervicogenic headache patients. It is considered that, further studies including more subjects of various job categories and comparing the outcomes.

Purpose: The purpose of this study is to find out the cognizance of medical device safety information (MDSI) monitoring in the hospital and oriental hospital workers, and the different aspect of MDSI between oriental medical devices and medical devices. Methods: The survey was performed both in the oriental medicine hospital and general hospital. The survey had 16 items; 2 items basic questions, 5 items in the awareness of MDSI, 5 items in the education of MDSI, 4 items in the necessity of defining oriental medical devices and differences between general and oriental medical devices. A total of 120 hospital worker were participated; 60 oriental medicine hospital workers and 60 general hospital workers. They had worked in the oriental medicine or general hospital associated with 'Medical Device Safety Monitoring Center, Dongguk University Ilsan Hospital' in 2019 and 2020. Results: The cognizance of MDSI was high both in oriental medicine hospital and general hospital workers and there were no significant differences between oriental medicine and general hospital workers. When we divided the hospital workers into the senior workers who had worked for over 3 years and junior workers for less than 3 years, the senior workers had higher awareness of MDSI than junior workers. However, the cognizance of education of MDSI was high which was not different between senior and junior workers. Both hospital workers thought that it was necessary to define oriental medicine device legally and the oriental medical device might have low risk and less side effect than medical device. Conclusion: The cognizance of MDSI was high and there was no significant differences between oriental medicine and general hospital workers. Because the senior hospital workers had higher recognition of MDSI, we need to provide the continuous education program for junior hospital workers. Although oriental medical device are thought to be safer than medical device, we need to have a legal definition.

When oil tankers, large passenger ships and cargo ships sink under the sea owing to various maritime accidents, the residual cargo oil or fuel oil in the such vessels could pose direct risk to factor for the marine environment and it require safe and rapid removal. Although domestic and foreign salvage companies are adopting various recovery methods and technologies with customizations according to each site during recovery operations studies on reasonable assessment modules for the operation process are relatively insufficient. In this study, the data from trapped-oil recovery operations performed at different site conditions were collected and analyzed in order to designed an operation assessment module, define the operational process steps in terms of preparation, implementation and completion, and derive key factors for each detailed process. Subsequently, the module was designed in such a way as to construct performance indicators to assess these key factors. In order to exclude subjective opinions from the assessment as much as possible, the assessment each item was constructed with indicators based on data that could be evaluated quantitatively and its usefulness was verified by applying the module to the trapped-oil recovery operation cases. We expect this the method and the technology assessment module for the trapped-oil recovery operation on sunken vessels will help to verify the adequacy of the trapped-oil recovery such operation before or after. Furthermore, it is expected that the continuous accumulation of assessment data and feedback from past or future operation cases will contribute toward enhancing the overall safety, efficiency and field applicability of trapped-oil recovery operation.

The epidemic of COVID19 caused a big change in design collaboration, which has been conducting using face-to-face interaction. Designers actively used video conferencing and online document tools in situations where face-to-face meetings were difficult, and this gave them an opportunity to experience that non-face-to-face collaboration can be more effective in a specific design process. In this regard, this study attempted to find out which activities during the design process are more compelling in face-to-face collaboration or non-face-to-face collaboration. To do this, three user experience design projects conducted after the COVID19 epidemic were analyzed through a retrospective interview method. As a result, during four design stages, 'Discover, Define, Develop, Deliver', face-to-face collaboration is necessary for the areas that require creative problem solving through active interaction. In contrast, non-face-to-face collaboration is preferred and more effective when designers need their own space and proceed their design work. In addition, the aspects of design tools supporting non-face-to-face collaboration were also illustrated. Findings discovered through this study are expected to contribute to research on the design process later.

This study was conducted to derive implications for the dissemination and expansion of subtropical crops in farms. To this end, the cultivation trends and main producing areas of promising subtropical crops in Korea were analyzed. Analysis results found that the cultivation area of crops, excluding mango, was stagnating or decreasing. The main producing areas of domestic subtropical crops are located on Jeju Island (mango, dragon fruit), in Gyeongsangnam-do (papaya), and in Jeollanam-do (turmeric). Guava and Yeoju could not define the main producing area. For all crops, the percentage of cultivated area in the top 10 regions was high, but only half of the regions maintained the ranking. These results imply that the introduction and abandonment of subtropical crops are frequent. The dissemination and expansion of subtropical crops are justifiable in terms of responding to climate change in the future and creating new income for farms. Therefore, government support policies and agricultural promotion agencies need to be established.
The military pension deficit is increasing due to an increase in the average life expectancy and pension option rate, and a significant reason for this is estimated to be a continued increase in the number of military pension recipients. In terms of the soundness of military pension finances, this paper uses the Markov chain model to validate the stability of the military group, suggesting the direction of future military pension system in terms of the ratio of pension receipts to employees, and verifying the feasibility of the method applied through verification. Through this paper, we have confirmed that the initial 45,270 military personnel converge to 43,141 after a certain period of time and reach a stable state, which is expected to help us to estimate the long term size of military pension recipients to confirm the direction of national financial support. Military man who are eligible for pensions for more than 20 years have a relatively low rate of turnover or retirement compared to ordinary private groups, making it easier to define their status and simplify state transition probabilities. Therefore, it is expected that the sustainability of the military pension will be confirmed from a long term perspective by viewing the military group as a system and applying it to the Markov chain model by checking the probability of transfer of status such as promotion, maintaining the current grade, and retirement during the period.

In recent years, many construction projects become large and complicated, and construction accidents also steadily increase, which grows interest in the safety and maintenance during construction. Many of the construction accidents are related to temporary construction and structures, but the safety evaluation and management during construction are unclear and indefinite due to the short operating period and continuous change in the formation of the temporary structure. The system support, which is one of the temporary structures to support the pouring load of concrete, was proposed to easily install and dismantle members with connection parts pre-manufactured. The use of the system support is increasing to improve the safety of the temporary structure during construction. However, the system support, which consists of multiple members, still has uncertainties in connectivity between members and supports of vertical members. Therefore, this study analyzed the structure, load, and accident cases of the system support to define the damage scenarios for member connection, support condition, and lateral displacement. The decrease rate of the critical load was analyzed according to the damage scenarios based on the defined unit structure of the system support. In addition, this study provided vulnerable members for each damage scenario, which could induce instability of the temporary structures during design, construction, and operation of the structure.
To learn statistics meaningfully, we must provide an opportunity to experience the process of solving statistical problems with actual data. In particular, exploration questions at the problem setting stage are important for students to successfully guide them from the beginning to the conclusion of the statistical problem solving process. Therefore, in this study, a mixed research method was carried out for the exploration questions of pre-service mathematics teachers during the problem setting stage. As a result, some pre-service mathematics teachers categorized incorrect statistical questions because they did not clearly define the meaning or variables of the questions in the process of categorizing them from possible questions. In addition, questions that cannot be solved statistically were categorized due to misconceptions about statistical knowledge. Second, only 50% of the pre-service mathematics teachers met all 6 conditions suitable for solving statistical problems, while there maining they met only a few conditions. Therefore, the conclusion of this study is as follows. First of all, they should be given the opportunity to experience all the statistical problem solving processes through teacher education because they do not have enough experience in statistical problem solving. Secondly, since the problem setting stage is very important in the statistical problem solving process, a series of subdivided processes are also required in the problem setting stage.

Although the deterioration of bridges may occur due to various causes, one of the representative causes is that the chloride used for deicing in the winter penetrates bridge members and results in corrosion. This study aims to quantify the ageing degree resulting from the corrosion of a bridge, apply it to the inelastic dynamic analysis model of the bridge, perform a seismic fragility analysis, and evaluate the relationship between the ageing degree and the seismic fragility curve. It is important to appropriately define the threshold values for each damage state in seismic fragility analyses considering the ageing degree. The damage state was defined using the results of existing experimental studies on the characteristics of the deterioration in the displacement ductility capacity of the pier, according to the ageing degree. Based on the seismic fragility analyses of six types of bridges divided by three types of bearing devices and two pier heights, it was found that the seismic vulnerability tends to increase with the ageing degree. The difference in seismic vulnerability with respect to the ageing degree exhibits a tendency to increase as the damage state progresses from slight to moderate, severe, and collapse.
