The logistics industry is becoming increasingly important as it is closely linked to our daily lives, storing and transporting the goods and resources that businesses and consumers need. With its growing importance, the logistics industry strives to provide efficient and sustainable services through innovations and artificial intelligence are being used to optimize logistics networks, make transport more environmentally friendly, and more. Research and improvements are being undertaken in various domains, such as logistics network optimization and environmentally friendly transportation through technological innovation and artificial intelligence; however, there still needs to be more research in certain aspects of the logistics industry. In particular, devising an optimized stowage plan for vehicle carriers, considering various factors, involves a significant degree of complexity and remains an under-researched area. This paper studies the loading and unloading algorithms that enable to quickly and efficiently establish stowage plans for vehicle carriers, reflecting a variety of considerations and rules for stowage planning.

This study is on management present and improvements on National Records Designation System. National Records Designation System is a system that supports management and preservation of changes of records designated by the government through consideration that such records are worth preserving permanently nationally among records acquired by individual or organization. This system is meaningful in a way that it established systematic foundation to hand down by informatizing historic private records which are in danger to be lost or damaged due to lack of proper care. However, compared to the number of designated records, the information that could be practically drawn from such records are limited. This triggered this study to be launched. National Archive sometimes promotes designation and management of National Designated records. Yet archival information service offering access of user to national designated records are very rare. I conducted survey and interview of managers, field research, and documentary research of 10 records holding institution that keeps national designated records currently. I considered that current management status of National Records Designation System can be figured out minutely through these research. As a result of such research, most of the records holding institutions offered display as their least archival information service. The objective of records informatization was to utilize the records. Also further plans on information service related to records and various utilization were suggested. records holding institution manager did not give positive answer on effect of designating national designated records and cooperation between National Archive. Support to National Archive only focused on preservation. For national designated records holding institution designated after 2011 were not getting proper support. In addition, National Archive's support rarely met records holding institution's need. In such circumstances, things to consider for improvements of National Records Designation System is as following. First, designation of national designated records should be based on the utilization of the record. Each records holding institution's willingness to utilize corresponding records and National Archive's ability to draw the willingness out should be considered. Also, it shouldn't be left as mere complementary policy of National Archive's selecting policy. Second, for National Records Designation System to be managed permanently, it should be changed as the system that supports enhancement of private records management. The aim should point to the direction where private can manage and preserve the records on their own. Third, There needs to be changes on the subject and process of national designated records designation. National designated record is the record that was considered valuable by the government among private records. Thus, such records should be the best one to show private field. Accordingly, records that represent contemporary society and include various states and contents should be chosen to be designated. Moreover, public discussion be formed by citizens and related professionals in order to properly select the record.

This study examined principles and techniques of efficient water quality management as well as total coastal pollutant loads and the relevant examples in the advanced countries from the viewpoints of water quality improvement and pollution control in coastal areas. The problems and improvements in an estimation of the current total pollutant loads were also pointed out. In addition, discussion was made on the relationship between total pollutant loads and environmental capacity as well as particulars requiring extensive examination on access to and study on water quality model used as prediction tool for marine environment. Furthermore, this study proposed details of and improvement plans for water quality control to be reflected and absorbed into systems and policies related to coastal water quality. In coastal areas, which are subject to total coastal pollutant loads, it is necessary to calculate pollutant loads reduction and allocation, to propose them in detail in statement in relations to new pollution sources for the corresponding projects or plans in environmental impact assessment and prior environmental review system. Also, in relations to regional plans for coastal management, the local government concerned must focus more on environmental management plan to implement data on pollution sources and pollutant loads flown into sea areas under basic jurisdiction, therefore it is required to actively respond to expansion and introduction of total coastal pollutant loads system in the future. Total coastal pollutant loads system must be expanded and executed by considering characteristics of sea area and changes in the environment of land. For pollution sources in land, the competent authorities in charge of coastal environment will need to initiatively administer supervision, monitoring activities and achieve integration and operation of the related laws by preparing legal bases for management system or adjusting the related laws.

The Highway Capacity Manual specifies procedures for evaluating intersection performance in terms of delay per vehicle. What is lacking in the current methodology is a comparable quantitative procedure for ass~ssing the safety-based level of service provided to motorists. The objective of the research described herein was to develop a computational procedure for evaluating the safety-based level of service of signalized intersections based on the relative hazard of alternative intersection designs and signal timing plans. Conflict opportunity models were developed for those crossing, diverging, and stopping maneuvers which are associated with left-turn and rear-end accidents. Safety¬based level-of-service criteria were then developed based on the distribution of conflict opportunities computed from the developed models. A case study evaluation of the level of service analysis methodology revealed that the developed safety-based criteria were not as sensitive to changes in prevailing traffic, roadway, and signal timing conditions as the traditional delay-based measure. However, the methodology did permit a quantitative assessment of the trade-off between delay reduction and safety improvement. The Highway Capacity Manual (HCM) specifies procedures for evaluating intersection performance in terms of a wide variety of prevailing conditions such as traffic composition, intersection geometry, traffic volumes, and signal timing (1). At the present time, however, performance is only measured in terms of delay per vehicle. This is a parameter which is widely accepted as a meaningful and useful indicator of the efficiency with which an intersection is serving traffic needs. What is lacking in the current methodology is a comparable quantitative procedure for assessing the safety-based level of service provided to motorists. For example, it is well¬known that the change from permissive to protected left-turn phasing can reduce left-turn accident frequency. However, the HCM only permits a quantitative assessment of the impact of this alternative phasing arrangement on vehicle delay. It is left to the engineer or planner to subjectively judge the level of safety benefits, and to evaluate the trade-off between the efficiency and safety consequences of the alternative phasing plans. Numerous examples of other geometric design and signal timing improvements could also be given. At present, the principal methods available to the practitioner for evaluating the relative safety at signalized intersections are: a) the application of engineering judgement, b) accident analyses, and c) traffic conflicts analysis. Reliance on engineering judgement has obvious limitations, especially when placed in the context of the elaborate HCM procedures for calculating delay. Accident analyses generally require some type of before-after comparison, either for the case study intersection or for a large set of similar intersections. In e.ither situation, there are problems associated with compensating for regression-to-the-mean phenomena (2), as well as obtaining an adequate sample size. Research has also pointed to potential bias caused by the way in which exposure to accidents is measured (3, 4). Because of the problems associated with traditional accident analyses, some have promoted the use of tqe traffic conflicts technique (5). However, this procedure also has shortcomings in that it.requires extensive field data collection and trained observers to identify the different types of conflicts occurring in the field. The objective of the research described herein was to develop a computational procedure for evaluating the safety-based level of service of signalized intersections that would be compatible and consistent with that presently found in the HCM for evaluating efficiency-based level of service as measured by delay per vehicle (6). The intent was not to develop a new set of accident prediction models, but to design a methodology to quantitatively predict the relative hazard of alternative intersection designs and signal timing plans.

In this study, a reference model is constructed that provides architects or designers with sufficient information on the intelligent service facility that is essential for U-City space configuration, and for the support of enhanced design, as well as for planning activities. At the core of the reference model is comprehensive information about the intelligent service facility that plans the content of services, and the latest related information that is regularly updated. A plan is presented to take advantage of the database of list information systems in the Public Procurement Service that handles intelligent service facilities. We suggest a number of improvements by analyzing the current status of, and issues with, the goods information in the Public Procurement Service, and by conducting a simulation for the proper placement of CCTV. As the design of U-City plan has evolved from IT technology-based to smart space-based, reviews of limitations such as the lack of standards, information about the installation, and the placement of the intelligent service facility that provides U-service have been carried out. Due to the absence of relevant legislation and guidelines, however, planning activities, such as the appropriate placement of the intelligent service facility are difficult when considering efficient service provision. In addition, with the lack of information about IT technology and intelligent service facilities that can be provided to U-City planners and designers, there are a number of difficulties when establishing an optimal plan with respect to service level and budget. To solve these problems, this study presents a plan in conjunction with the goods information from the Public Procurement Service. The Public Procurement Service has already built an industry-related database of around 260,000 cases, which has been continually updated. It can be a very useful source of information about the intelligent service facility, the ever-changing U-City industry's core, and the relevant technologies. However, since providing this information is insufficient in the application process and, due to the constraints in the information disclosure process, there have been some issues in its application. Therefore, this study, by presenting an improvement plan for the linkage and application of the goods information in the Public Procurement Service, has significance for the provision of the basic framework for future U-City enhancement plans, and multi-departments' common utilization of the goods information in the Public Procurement Service.

This study was conducted to investigate the relationships among service quality, perceived benefit, perceived value and behavioral intention as perceived by franchise snack bars customers. The service quality of franchise snack bars' was tested in three sub-dimensions: environmental quality interaction quality, and outcome quality, which are based on Brady & Cronin's third-dimensional model. A total of 450 survey questionaires were distributed from March 9th to November 12th in 2015, of whi 411 questionnaires were deemed suitable for statistical analysis. SPSS 20.0 program was employed to conduct frequency analysis and reliability analysis, while AMOS 20.0 program was used to test the hypotheses. The results revealed that all three elements of service quality have a positive impact on perceived benefit. In particular, the outcome quality element had the greatest influence on perceived benefit. In sum, customers of a franchise snack bar considered outcome variables such as food taste, reasonable amount, and general quality of food as the most important factors to fulfill the benefit. This results suggest that Korean snack bar franchise companies need to consider improvements to outcome quality features, such as food quality. In addition, perceived benefit was a critical antecedent of perceived value, which was itself a significant predictor of behavioral intention. In conclusion, this study applied the means-end chain theory on franchise sank bar segmentation, as well as three dimension service quality model as developed by Brady and Cronin, and found results that will enable meaningful strategics for snack bar foodservice segmentation in pursuit of the development of efficient business plans, and that can be utilized as a theoretical data for future studies.

Objective : The purpose of this study was to verify the effectiveness of home-visit occupational therapy in stroke patients. Methods : Two patients with stroke who applied for home-based occupational therapy services at a health center in Seoul were enrolled. The home-visit occupational therapy program evaluates the subject's daily living, task performance, cognitive, and emotional functions, sets occupational therapy goals and plans interventions based on a client-centered approach. Occupational therapy programs consisted of 12 sessions based on the client's major problems. Results : COPM scores improved in both cases, there was an improvement in COPM scores, and in Case 2 there were improvements in MBI and K-MMSE scores. There was also an improvement in KGDS scores in Case 1. Conclusion : Home-visit occupational therapy was found to be effective in improving daily activities, cognition, and mental function of stroke patients. During home and community integration, continuous and continuous rehabilitation services need to be activated from institutional rehabilitation to community-based rehabilitation. Active home-visit occupational therapy is needed to promote physical, cognitive, mental and social access in stroke patients discharged from hospitals.

The purpose of this study is to analyze the guidelines and content of visual landscape planning according to the Landscape Law and to suggest improvements for it. The landscape planning guidelines were analyzed and landscape planning reports were reviewed and compared. To analyze the landscape planning guidelines, we conducted an expert survey and derived the results through statistical methods, such as t-test and importance-performance analysis(IPA). Both landscape planning reports were selected from among metropolitan cities, medium-sized cities, and counties. We analyzed and compared the reports with the landscape planning guidelines. The results of this study are as follows. The stage of visual landscape resource survey progressed systematically, but it was not practical for actual planning because of the excessively detailed guidelines. On the other hand, a greater variety of methods and techniques should be suggested for the landscape structure analysis. At the schematic planning stage, establishing contents suitable for the local government's identity and related plans is necessary. In addition, more detailed guidelines should be included in the landscape planning guidelines. At the master planning stage, the planning qualities and contents differed from cities and counties, so more substantial and detailed guidelines are necessary for the scope and contents. We suggested that some additional items be included such as the synthesis of landscape resource surveys and the viewpoint plan.

Every crime involves a victim and an offender. The offender, from the start of the criminal investigation, is considered as a suspect. After prosecution, he/she becomes the accused, and under consitutional law and criminal procedural law, has the right to enforce the contests of the acts. On the other hand, the victim or his/her family, despite being the person harmed, has very few and comparatively weak rights. To overcome this problem, the Korean criminal justice has recently recognised 'the protection and support of the victim' as a major proposition, and the police as well as the prosecutor's office have been releasing improvement plans for the protection of victims. Setting the above as the background, this thesis deals with the current victim protection acts and discusses the methods to improve them. This study will investigate a more reasonable and effective method of victim support and protection. Currently korea's laws regarding victim protection are not satisfactory, however it is fitting to say that it is certainly an external outline of what it should be. This has been due to the enforcement and creation of 'criminal victim protection' and has acted as a key to more improvements ever since. Despite this, the lack of commitment in human and financial resources to enforce these laws has now produced a possibility of the laws proving to be nothing but an unopened letter. To prevent this from happening, the victim nothing but an unopened letter. To prevent this from happening, the victim protection related laws need to be revised to be more practical and secure. Despite this, the lack of commitment in human resources and financial resources to enforce these laws has now produced a possibility of the laws proving to be nothing but an unopened letter.

Due to the rapid process of industrialization the cities of Korea confront changes of climate, destructions of the habitate and decrease of the green. Recently Seoul and other local governments have implemented policies and projects to improve the environmental surroundings. In reality, however, those policies and projects face difficulties in the course of implementation. The fact that there are no concrete regulations and specific legal procedures turns out to be one of the main difficulties. The aim of this study is to present specific plans and methods of wall-planting and to provide basic guidelines for the future direction of wall-planting and offer ideas of facilitating wall-planting. This study is based on questionnaires from specialists of landscape architecture through individual interviews and/or e-mails. The questionnaire is consisted of following 4 sections. 1. Show the experts current regulations and/or legal procedures and ask them improvements and suggestions. 2. Ask them choose matters of the highest priority by using Ricardo's diagram method. 3. Ask them to make a graded list in terms of the location and method of wall-planting. 4. Study the maketability of the wall-planting products currently in circulation. The city of Seoul and the Ministry of Environment recommend that trellis and/or planting inducement structures be installed on the building wall by regulation. The specialists responded to the questionnaire advocate that green wall without trellis should be allowed as green zone. Therefore regulations concerning the wall-planting should be determined specifically according to the characteristics of individual plants and walls. It has been urged that legal aid and social support must be reinforced to establish rules dealing with wall-planting. The respondents also point out that significant cutting down of the tax is far more effective in accelerating the wall-green instead of administrative support. The highest priority in terms of planting has been given to sound-proof wall, retaining wall and building wall. Concerning the maketability of the wall-planting products, panel products are recommended for early-planting and building planting. It has been suggested that the research and study of new materials and species be done in advance.
