The port BIM technology has many problems such as lack of relevant system, high cost of BIM infrastructure construction, and process difference of existing domestic inter-industry. Since the port facilities as national key industries are managed and operated by public organizations, it is necessary to integrate IT resources and have a system that needs collective construction and joint utilization management. In this paper, we proposed the convergence of cloud computing technology and BIM as a way to reduce the infrastructure cost required for port BIM operation and to provide various BIM services for domestic process. To do this, we collected system requirements based on demand surveys of port staff and designed a BIM browser that provides IFC-based BIM server and customized services to reduce infrastructure cost in cloud computing environment. In terms of infrastructure, we designed cloud-based IaaS to support cost reduction, which is an essential component, and designed SaaS to support customized services in terms of services. We will perform performance verification with focus on whether port BIM servers and browsers have reached a level where they can manage four BIM models with different types and capacities.

The morbidly rate of acute illnesses for last two weeks for all households was 29.6%, and the rate of use of medical facilities to treat acute illness was 98.3%. The morbidly rate was highest between the ages of 60 and 69, with a rate of 35.4%. The higher their ages and the lower their educational levels were, the higher the morbidly rate was. The morbidly rate of chronic illnesses for one year for all households was 19.2%, and the rate of use of medical facilities to treat chronic illness was 92.8%. The elderly over 70 years old had the highest morbidly rate of 37.2%. The higher their ages and the lower their educational levels were, the higher the chronic illnesses rate was. For the rate of use of medical facilities to treat acute diseases, the use of PHPs was 89.5%, accounting for the majority of the time. However, for chronic diseases, hospitals and clinics were used more often, with a rate of 48.9%, compared to the use of PHPs, 40.2%. Their previous experiences on the use of PHPs one year before the survey showed that 94.8% used PHPs, 72.2% just visited them, not for the purpose of getting any medical assistance, and 73.3% received health education from PHPs. 98.5% remembered the locations of PHPs, 98.6% thought that PHPs were helpful for their health management, and 84.3% said that PHPs were playing great roles in development of their communities. 97.4% said that they found PHPs necessary. They understood the main job of PHPs as in the order of disease treatment, vaccination and health counseling. The work that they mostly wanted PHPs to do was health counseling and health management, which 31.6% answered. 88.9% said the examination fee was not expensive, 98.4% said CHPs were kind, and 97.0% said they were satisfied with the services at PHPs. Complaints about PHPs included a lack of a variety of medications, said by 42.9%, and poor facilities, by 15.8%. According to the above results, it is concluded that local residents on survey were frequently using PHPs due to their geographical and economical conditions. Also, the residents appeared to be satisfied with the services at PHPs, and they had a high demand for public health service as well as disease treatment. Considering the complaints about medications and medical facilities and equipment, active supports are required to manage PHPs in a way it can provide desirable services to the residents in remote villages through the readjustment of PHPs' functions, reinforcement of facilities and equipment and enhancement of CHPs ' training.

Elderly welfare housing refers to a residential facility with diverse medical and welfare services for cohabitation of elderly. Especially, community shared spaces in the elderly welfare housing plays an important role as a place for community and leisure activities that enhance vitality of elderly life. The purpose of this study was to investigate types, planning characteristics and actual utilization of community shared spaces in for-profit elderly welfare housing. Eight for-profit elderly welfare housing facilities in Seoul and Gyeonggi province were selected for this study and categorized into small-, medium- and large-scale facilities based on the number of housing units. Community shared spaces in the elderly welfare housing were classified into six space types: social space, education space, exercise space, medical space, convenience space and leisure space. Findings are as follows. Small-scale elderly welfare housing facilities with less than 100 housing units had fitness centers, clinics, restaurants, convenience stores and hobby rooms which were required by law. All community shared spaces were planned on a single level. Fitness centers was found the most frequently used while the other spaces were not used very frequently. Medium-scale facilities with 100 to 299 housing units had multi-purpose halls, libraries, swimming pools, indoor and/or outdoor driving ranges, physical therapy centers, saunas, karaokes and so on. Most community shared spaces were found frequently used. Large-scale facilities with 300 or more housing units had religion rooms, community halls, hair salons, pharmacies, etc. In most facilities, community shared spaces were planned in distributed locations.

PURPOSES : This study intends to estimate the tangible benefits derived from the integration of operations of an Express Intercity Bus Terminal and a Highway Service Area. METHODS: For the study, a highway service area was chosen to function as a bus terminal, integrating its services with that of a nearby bus terminal plagued by operating losses. The exercise also helped improve mobility owing to the introduction of local buses between the terminals and utilization of the existing infrastructure such as rest areas. Thus, a terminal that was not being utilized for its intended functionality was integrated with an existing facility to improve the utilization of both and subsequently aid local development. The impact of the exercise was then measured by evaluating the variation in utilization efficiency, operating costs, travel time between two regions (Seoul-Jeomchon and Seoul-Geumsan), and the social costs before and after the integration of the two facilities. RESULTS :The impact of the integration was an increase in utilization efficiency, a decrease in operating cost, a decrease in travel time, and a decrease in social cost in both the regions. The benefits of improved utilization and cost saving can be passed on to the citizens in the form of discounts. A local power generation facility will eventually replace the bus terminal, which can revitalize the local economy. CONCLUSIONS :The integration of the highway service area with the bus terminal is expected to have a win-win effect on the passengers as well as the operators. The study also proposes a sustainable strategic plan for existing terminals and rest areas to implement a method to compete with KTX transportation.

The problem of care of patients and families with Alzheimer's disease has become a conscious raising social policy issue in Korea. The government of the Republic of Korea has become cognizant of the situation and has begun searching for ways to remedy it. Thus, there is a need for a comprehensive under-standing of the situation in which patients and their families are struggling and the enormous problems of care. With a realization of the urgent need, this study was done to investigate the situation and the care needs of families with patients with Alzheimer's Disease, and to compare the effectiveness of services utilized by the families in terms of cost and effects on patient's conditions and on family live. The Subjects for the study were 29 families with hospitalized patients, 25 families utilizing hospital outpatient clinics, 14 families utilizing day care facilities, and 16 families with homebound patients. A total of 84 families were interviewed by four trained interviewers using structured and semistructured questionnaires. The data produced from these interviews included : the patient's stage of Alzheimer's disease, patient's bizarre behavior, hours spent on patient care per day, family burden and quality of life, direct and indirect costs encountered in the care of patients, and the families' evaluation of the effectiveness of the services received. The data were analyzed to determine the relationships between family charactersistics, patient's conditions and services utilization. The effectiveness of each of the service entities was assessed through families evaluation and hoped for service and comparisons were made between services in terms of the cost-effectiveness ratios. After initial comparison of cost-effectiveness ratios, further analysis was done to compare between groups for incremental effectiveness for each incremental unit of cost to determine the most cost-effective service entities. The findings of the study are as fellows : 1. The choice of living arrangement and the types of services are a function of the stage of Alzheimer's condition and the economic status of the family. 2. Comparision of the cost of care showed that most expenses were encountered in by families with hospitalization, families using outpatient services, and families using day care services in that order. The least expense was involved in the care of homebound patients. The economic burden felt by families was in the same order as expenses. 3. The average number of hours spent on daily patient care was 9.9 hours for the outpatient clinic users, 9.7 hours for homebound patients, and 5.4 hours for day care users. 4. There were significant differences in the patient's conditions (CDRL), bizarre behaviors and the families's burden by living arrangement and /or types of service. However, no significant difference was found between groups in the family's quality of life. 5. The families rated the services of day care center as most effective for the care of the patients and families, except for a few families who had experienced some improvement in the patient's conditions. The outpatient clinic users expressed psychological comforts mainly in that the patient was being taken care of. For those hospitalized patients, families expressed the comfort of being relieved of the burden of care and that the patient is being professionally cared for. Form the analysis of the costs, hours of patient care, patient's bizarre behaviors, family's quality of life and burdens, and family's evaluation of services, it is concluded that up to the mid stage of Alzheimer's condition, the utilization of day care center services is found to be the most cost-effective, and toward the end stage of the Alzheimer's disease, it is hoped that there will be a establishment of long term or short term in-patient facilities for the protection of patients and preservation of the integrity of families for less cost. Thus. it was concluded that the family centered system of care is the most effective for Korea with systematic support systems developed for the care of patients and their families according to the needs of families as the patient's condition deteriorates.

After the COVID-19 outbreak in 2019, the spread of COVID-19 has not been easily caught despite preventive measures in each country. The spread of COVID-19 has hit the world, especially in the economic and tourism sectors. Countries around the world are easing restrictions on the movement of vaccinated people in preparation for the post-corona era. Under the name of "Vaccine Passport," "Vaccination Certificate," and "Digital Health Pass," vaccination measures are being implemented to allow vaccination recipients to use multi-use facilities. However, there is no international agreement on the movement of countries, and each country has its own immigration policy. In order to return to pre-corona daily life, global agreements must be reached from the movement of vaccinated people between countries, and standards and implementation methods must be determined. This study focuses on the implementation and utilization of vaccination certificates suitable for the COVID-19 era. We will look at the spread of COVID-19 and its international response policies. In the case of COVID-19, we will investigate why vaccination certificate installation should be standardized and how far the current standardization has been discussed, and discuss the characteristics of vaccination certificate installation and considerations. In order for the immunization certificate discussed in the previous chapter to be recognized internationally, institutional and technical considerations are identified and security factors that may occur in each implementation are also presented. Finally, the international recognition case of vaccination certificate is discussed, and the method of installation and utilization of vaccination certificate is proposed. This paper can be used as a policy because of its timeliness in studying the standards of vaccination certificates and considerations for international recognition to restore movement between countries in the spread of COVID-19. In addition, if other infectious diseases occur in the future or similar cases where movement between countries is restricted, it can be used as a reference to support the movement of verified people.

All-IP network requires change of the existing IP network engineering methods as the convergence service market between communication and broadcasting industries using IP network is growing rapidly. Especially the video services like IPTV require more strict transmission quality and higher bandwidth than the existing data services. So it is difficult to design All-IP network by the over-provisioning method which used to be used for the existing IP network design. It also requires a heavy investment which becomes one of big obstacles to the IPTV service expansion. In order to reduce the investment costs, it is required to design an optimized network by maximizing the utilization of the network resources and at the same time maintaining the customer satisfaction in terms of service quality. In this paper, we first analyze the effects of IPTV traffic on the existing internet. Then we compare two traffic engineering technologies, which are dimensioning without admission control and dimensioning with admission control, on the All-IP network design by simulation. Finally, we suggest cost effectiveness of traffic engineering technologies for designing the All-IP network.
