I had an interview with some unemployed career staffs who had retired and worked for more than twenty years in order to research impacting elements on reemployment for l retired special security government officials. This interview included an officer and a consultant for supporting employment in order to explore compacting elements on retired security government official's reemployment. Looking over analysis results, first, there is a shortage of reemployment opportunities and information. The job applicant's employment requirements are not in accordance with the company's employment conditions. They don't have enough professional experience necessary for employment. There is no positive employment supporting counterplan or vocational education program in the organization. Second, their insight about finding a job is high for the current employment market condition. The reemployment offices have a very difficult task because job applicants prefer a full-time job which offers long term work and guarantees a social position. Third, it is a huge obstacle to undertake going into various enterprises and fields because they don't have the right mind set and enough preparation for reemployment. Moreover, they would prefer to depend on organization employment support rather than getting a new job by themselves when they don't possess other careers' qualifications. Finally, they know that social networks and personal connections are extremely important in obtaining vocations, but actually have poor social networks and few personal connections. Accordingly, Their organization and related persons need to reflect on analysis results about impacting elements on reemployment for retired special security government officials.

This study was conducted to investigate the effect of the total sugar contents on chemical, smoke and sensory properties and to estimate the desirable chemical composition contents from sensory properties in flue-cured leaf tobacco. The leaves used in the study were in 2005 and in $1997{\sim}2006$ crop year. Nicotine and total nitrogen contents, filling value, impact, irritation and bitterness were reduced with increasing the total sugar contents of B2O(leaf) and C2L(cutters), whereas tar and CO contents and puff number were increased. The desirable sugar contents estimated from the best overall tobacco taste of smoke were 25.9% in B2O and 26.9% in C2L. All of regression equations among total sugar/nicotine ratio, total sugar, nicotine and total nitrogen contents were significant($p{\leqq}0.05$). There were no significant difference between the 4 grade(A2O, B2O, C2L, D2L) average and the whole plant(12 grade) average contents in total sugar, nicotine and total nitrogen contents. All of regression equations between the ratio of each grade content to the average content of twelve grades and stalk position[number ; from bottom(1) to top(12)] in total sugar, nicotine and total nitrogen contents were significant($p{\leqq}0.05$). The estimated desirable chemical properties which based on the best overall tobacco taste were 23.2% of total sugar, 2.39% of nicotine, 9.7 of total sugar/nicotine ratio, 2.57% of total nitrogen, 1.08 of total nitrogen/nicotine ratio in average of four grades. With decrease the total sugar content from 32.0% to 24.0%, filling value was enhanced by 14.1% in average of B2O and C2L, also tar and CO contents of smoke were decreased by 13.2% and 10.5%, respectively. These results suggest that the estimated desirable chemical composition contents may be useful to produce good leaf tobacco, and to enhance filling value and to reduce tar and CO contents of smoke in flue-cured leaf tobacco.

This study aims to understand the background and characteristics of the UK's allotments, as the UK is one of the nations participating in allotment invigoration. This study will focus on approaches to policy, active governance, and socioeconomic impact. To address this, allotment-related issues, policies since the beginning of the 19th century were analysed. In addition to this, Sheffield City, UK, was selected as a specific case to analyse the framework of allotment management, active governance concerning allotment management, and the residents' perceptions of allotments through a questionnaire survey. It was found first that the UK government, since 1806, has been consistently producing localism policies aiming to devolve management authority into local governments, which actively obtain sites for allotments. Secondly, the structure of allotment management formed in active governance leads the overall maintenance, partnership, income generation, and monitoring of the allotments. Interestingly, the structure of the department organisation of local government in Sheffield established the position of community manager, who encourages community invigoration. However, a gap between socioeconomic aspects was found in which the allotment invigoration in lesser deprived areas outweighs the invigoration in more deprived areas. In contrast, according to the questionnaire survey, respondents in more deprived areas were more likely to be involved in allotment activities and the community. The key to addressing the socioeconomic gap in the context of allotment invigoration is the adoption of the Public-Community-Private-Partnership framework. This will be of great importance to longer-term promotion of beneficial allotment practices.

MLS (Mobile Laser Scanning) which is a scanning method done by moving the LiDAR (Light Detection and Ranging) is widely employed to capture indoor PCD (Point Cloud Data) for floor plan generation in the AEC (Architecture, Engineering, and Construction) industry. The movement and rotation of LiDAR in the scanning phase cause deformation (i.e. skew) of PCD and impose a significant impact on quality of output. Thus, a de-skewing method is required to increase the accuracy of geometric representation. De-skewing methods which use position and pose information of LiDAR collected by IMU (Inertial Measurement Unit) have been mainly developed to refine the PCD. However, the existing methods have limitations on de-skewing PCD without IMU. In this study, a novel algorithm for de-skewing 2D PCD captured from MLS without IMU is presented. The algorithm de-skews PCD using scan matching between points captured from adjacent scan positions. Based on the comparison of the deskewed floor plan with the benchmark derived from TLS (Terrestrial Laser Scanning), the performance of proposed algorithm is verified by reducing the average mismatched area 49.82%. The result of this study shows that the accurate floor plan is generated by the de-skewing algorithm without IMU.

Road surface measurement is an essential process for quantifying the degree and displacement of roughness in road surface management. For safer road surface management and quick maintenance, it is important to accurately measure the road surface while mounted on a vehicle. In this paper, we propose a sophisticated road surface measurement system that can be measured on a moving vehicle. The proposed road surface measurement system supports more accurate measurement of the road surface by using a high-performance line laser sensor. It is also possible to measure the transverse and longitudinal profile by matching the position information acquired from the RTK, and the velocity adaptive update algorithm allows a manager to monitor in a real-time manner. In order to evaluate the proposed system, the Gocator laser sensor, MRP module, and NVIDIA Xavier processor were mounted on a test mobile and tested on the road surface. Our evaluation results demonstrate that our system measures accurate profile base on the MSE. Our proposed system can be used not only for evaluating the condition of roads but also for evaluating the impact of adjacent excavation.

Interest in sustainable management based on the stakeholder perspective is expanding not only within an organization but also across the supply chain. For large companies that have established networks, sustainability management of the supply chain is now a factor that not only determines the social performance of the company as a whole, but also determines its long-term competitive position. Despite these changes in the business world, especially the proliferation of the sustainable supply chain management (SSCM) system, systematic research on SSCM has been lacking. In particular, there was a lack of empirical analysis on which factors promoted the establishment of the SSCM system for large companies and what's the effects of SSCM. In this regard, this study analyzes i) the impact of the social responsibility pressure of customers as external stakeholders and the CSR orientation of purchasing managers as internal stakeholders on supply chain transparency and partnership cooperation respectively, and ii) whether supply chain transparency and partnership cooperation can enhance corporate reputation. The samples used in this study were 69 large companies representing Korea. The results showed that the social responsibility pressure of customers and the purchasing manager's CSR orientation were positively related to the transparency of the supply chain. However, for partnership cooperation, only the purchasing manager's CSR orientation was found to have a positive and significant effect. Meanwhile, both supply chain transparency and partnership cooperation were positively related to the corporate reputation. At the end of the study, discussions on the implications of the results and future research directions will be presented.

The purpose of this study is to investigate the effect of emotional labor and job stress on patient safety management activities in emergency room nurse. Data were collected using self-report questionnaires from 143 nurses working in the emergency room of small and medium-sized hospitals. As factors influencing patient safety management activities, emotional labor, job stress, demographic characteristics, and work characteristics were investigated. Stepwise multiple regression analysis were used for factors affecting patient safety management activities. There were significant differences in patient safety management activities by age, experience in emergency room, position, work pattern, and intention to move to another department. In the regression analysis, the factors that had a significant effect on patient safety management activities were job stress and choice to work in the emergency room, and the explanatory power of these variables was 27%. It was found that the higher the job stress, the lower the patient safety management activity. In conclusion, it is necessary to manage job stress arrange departments according to individual needs to improve patient safety management activities of nurses in the emergency room of small and medium-sized hospitals.

This paper discusses the possibility of developing literary villages and book towns by examining the feasibility of place marketing for culture and art spaces from multiple perspectives. The aim is to point out the practicability of literary villages, moving away from building halls of fame for individual writers and artists and toward creating whole villages functioning as the centers of their local cultural scene, as well as suggest ways for contributing to regional revitalization and development of culture and art programs. To this end, "Kim Yujeong Literature Village," "Lee Hyo-seok Culture and Art Village," and "Hwang Soon-Won Sonagi Village" were selected; based on these, case studies were conducted and their actual operational status was explored. As a result, it was discovered that literary villages would function well as the centers of their local community if meaningful and interesting content is continuously developed with quality enhancement. This suggests a positive impact of place marketing, and to achieve this, it is necessary to open a new paradigm of local culture by differentiating from other cultural industries and securing a position as a new industrial sector. To this end, the paper suggests approaches such as small local literary groups with direct or indirect links to the literary village, or application of space and related works in the literary village with local education.

The turnout system of the sleeper floating tracks (STEDEF) on urban transit is a Anti-vibration track composed of a wooden sleeper embedded in a concrete bed and a sleeper resilience pad under the sleeper. Therefore, deterioration and changes in spring stiffness of the sleeper resilience pad could be cause changes in sleeper support conditions. The damage amount of manganese crossings that occurred during the current service period of about 21 years was investigated to be about 17% of the total amount of crossings, and it was analyzed that the damage amount increased after 15 years of use (accumulated passing tonnage of about 550 million tons). In this study, parameter analysis (wheel position, sleeper support condition, and dynamic wheel load) was performed using a three-dimensional numerical model that simulated real manganese crossing and wheel profile, to analyze the damage type and cause of manganese crossing that occurred in the actual field. As a result of this study, when the voided sleeper occurred in the sleeper around the nose, the stress generated in the crossing nose exceeded the yield strength according to the dynamic wheel load considering the design track impact factor. In addition, the analysis results were evaluated to be in good agreement with the location of damage that occurred in the actual field. Therefore, in order to minimize the damage of the manganese crossing, it is necessary to keep the sleeper support condition around the nose part constant. In addition, by considering the uniformity of the boundary conditions under the sleepers, it was analyzed that it would be advantageous to to replace the sleeper resilience pad together when replacing the damaged manganese crossing.
