The aim of this paper is to review the current knowledge management (KM) practices and their importance in the public sector of Saudi Arabia. Using the term "knowledge management in public sector", a search for available works was done in Google Scholar. In the first stage, the search for literature published under anytime choice was done in the first 10 pages of the search engine. Then another nine pages of Goggle Scholar were searched for more recent works published setting the time as 2014 to 2018. The search yielded 37 usable works for this review. The results of this literature search and review indicated that out of the 37 works reviewed, only three works were related to Saudi Arabia. Number of papers on factors of KM were maximum, many of them giving diagrammatic presentation of their results. KM modelling itself is not easy as only very few papers on KM modelling were available. Problems of too much reliance on qualitative data and hypotheses not matching with the literature backgrounds for them were also found. Considering the works related to KM, the number of papers in various categories may indicate the dimensions of KM to be considered when KM is implemented or evaluated in any public sector of any country. This applies to Saudi Arabian public sector organizations also. There is a fertile ground of research waiting to be investigated by researchers in Saudi Arabia.

Purpose: This study attempted to analyze the impacts of the backward linkage and output multipliers, and investigate the price fluctuation and the price forecast amongst the manufacturing sectors associated with food processing industrial output of Thailand. Research design, data and methodology: The Thailand Input-Output table with a size of 180 x 180 sectors from 2005, 2010, and 2015 was utilized while the secondary data of the time series from January 2002 to December 2021 were processed via a multiplicative model and Box-Jenkins model. Results: The backward linkage analysis indicates that canning and preserving of the meat sector majorly utilized the factors of production from the slaughtering sector; canning and preservation of fish and other seafoods sector largely used those factors from the ocean and coastal fishing sector; and the sugar sector used those of the sugarcane sector. Notably, the output multiplier analysis indicated that output multipliers of those 3 manufacturing sectors were highly increased; meanwhile the price fluctuation continually existed in all forms. Besides, the price forecast suggested that prices of chicken and sugarcane tended to be higher; whereas, the price of shrimp was unstable. Conclusions: Food processing industry contains the favorable components to be one of the industries of the future of Thailand.

Since 1990's, the Korean society, experiencing the low fertility and aging society, has been confronting with the threats in health care sector. The threats are the increases in the demand for health care, health care financial burden, and so on. In particular, the change of disease pattern and aging population result in the increases patients' demand for not only western medical services but also oriental medical services and complimentary medicine. Recently, the increases in availability of oriental medical services and the health care resources related to oriental medicine are raising some issues and conflicts in the Korean health sector. Theses circumstance required policy makers, central and local government, and public health sector to develop health policies related to oriental medicine and interface or integrate of traditional Korean medicine and Western medicine. For the near future, these issues will probably remain the focus of integration of traditional Korean medicine and Western medicine in public health sector. To cope with the threats in health care sector, one of the opportunities is to scale-up e public role of traditional Korean medical services. The main purpose of this study was to develop strategies to scale-up the Public role of traditional Korean medical services for the future society. The research questions are: what are the trends and problems in traditional Koran medical sector; what are the causes of or associated factors to the problems; how to cope with the problems and how to resolve the cause?; what are the health policy directions and its strategies that the government should take to cope with the future demand and the burden on health care sector? The results of this study are as follows. In order ta scale-up the public role of traditional medicine, this research offered health policy directions for traditional Korean medicine in response to a change environment of health care sector. There are four directions to be addressed: 1) the development of and investment in public oriental medicine infra-structure; 2) the development of public policy on oriental medicine; 3) modernization and globalisation of traditional Korean medicine; 4) the expansion of academic exchange between Western medicine and traditional Korean medicine. Finally, we discussed stakenholders' on traditional Korean medicine in the health care market. Then, public policy options for future society was suggested.

In this paper, we have proposed the sectorization method of the adaptive sector antenna and the new receiver structure for the CDMA wireless multi-media communication which uses multi-code and single-code. The sectorization and average BER performance of the adaptive sector antenna, which employs the proposed sectorization method, are obtained through simulation. The simulation results have shown that the sizes of sectors are properly controlled according to the distribution of the load and that the BER performance of the adaptive sector antenna is enhanced much more than that of the fixed sector antenna. Also, we have proposed two receivers, which are different from the positions to detect multi-code signals, for the multi-media communication. Each receiver has a simple cancellation scheme and two adaptive sector antennas, which are called the 1st adaptive sector antenna and the 2nd adaptive sector antenna, respectively. In this paper, the average BER performances of the receivers are compared through simulation. As the results of the simulation, we have recognized that all user' BER performances are greatly dependent on the positions to detect the multi-code signals. When we consider both system complexity and terget BERs of signals, we have concluded that the receiver, which detect multi-code signals in the 1st and the 2nd adaptive sector antenna, is appropriate for the CDMA wireless multi-media communication systems.

Recently, United Nations found that 38% of global carbon emissions are generated in the building sector, surpassing other industries (32%) and transportation (23%), and ESG is actively used as a way to reduce carbon emissions in the building sector, led by overseas advanced countries. In Korea, as the National Pension Service announced "Consider ESG with more than 50% of investment assets" this year, the move to introduce ESG in the building sector is accelerating, centering on construction companies and asset management companies. However, as the domestic ESG evaluation system is still mainly focused on corporate governance and social responsibility, interest in the environmental sector is lagging behind that of advanced countries. As ESG in the building sector is expected to grow rapidly over the next 10 years, I would like to suggest the following development directions. The first is the expansion of the incentive system. In order for the government to successfully implement policies related to ESG in the building sector, incentive system such as tax reduction and building standards should be expanded further than now in addition to negative systems such as rent restrictions and punishment taxes due to regulatory violations. Second, standardized ESG standards are established. Rather than creating an independent Korean ESG standard that is far from global standards, it is necessary to organize the common parts of global standards and evaluation methods and create and provide guidelines in the form of standard textbooks that can be used equally by all stakeholders. Third, it is an effort to link ESG in the building sector with Digital Transformation(DX). This is because actual energy savings and carbon emission reduction can be realized only when the operation method of the building sector, which is operated mainly by manpower, is digitalized and converted to an intelligent way.

This study derived production-production multipliers using a regional input-output table and estimated the induced effect of aggregates through the non-metallic minerals sector and the concrete products sector. In deriving the induced effect of aggregates, it is difficult to use the regional input-output table due to the sector classification problem. This study analyzed the non-metallic mineral sector, including aggregates, as aggregates sector, and the concrete products sector, which uses most of the aggregate production. By analyzing this, we attempted to alleviate difficulties caused by sector classification restrictions. In the process of estimating the induced effect, it was assumed that there was a decrease in aggregate production, and in the process of analyzing the concrete products sector, the effect of the decrease in concrete product production due to the decrease in aggregate production, that is, the decrease in production of one unit of aggregate was 0.8511 in the concrete product sector. The analysis was conducted on the premise of a decrease in unit production. Inducing effects within and between regions were calculated for the 17 metropolitan cities and provinces classified by the regional input-output table. The employment effect was also calculated, assuming a 10% production decrease to show differences according to the size of the aggregate and concrete product sectors in each region.

While promoting a variety of projects by using sea space, there has been a lot of social controversy among the stakeholders based on the results of the analysis. In particular, the benefits of fisheries sector were over-estimated and occurred a lot of opposition from fishermen and environment groups. In order to this solve, we have been studied focussed such as excavation of new projects, the method and result of the estimated benefits for fisheries sector. With regard to the tidal power plant of Garolim, we came up with five kinds of problems such as doing not reflect of the cost of the initial investment, over unit production, over unit price, excessive selection of breed, issues of cost of production in benefits study of fisheries sector derived previously. In order to these problems, we have derived new profitable projects based on the initial materials such as improvement of raising breed, discharge project of fingerlings and a small sea ranch project. As a result, previous study was analyzed in 30.2 billion won(1993), 54.8billion won(2009), but this study was estimated to 26.4 billion won and differences of benefits amount were occurred. In a previous study was calculated benefits by simple method, but this study came up with new projects for fisheries sector and because we estimated benefits considering new project. The method for benefits calculations for fisheries sector was not attempted in previous studies and in this study, we approached for the first time Also, in this study suggested new method to increase incomes fishermen such as development of suitable ranch breeding for the marine environment, ranch license(limited license), development of fisheries resources and the operation of fisheries facility. In the future, we hope to be helpful for the same field of study.

The Fourth Sector has been attracting attention as a means to solve the various problems plaguing modern society; it emerged to overcome the Third Sector's issues such as excessive reliance on the government and service model isomorphism, represented by social economy enterprises (Meadows, 1972; Howaldt & Schwarz, 2010). Social venture companies have been mentioned as key agents of the Fourth Sector (Gyeonggi Research Institute, 2018). However, the academic and policy concepts related to social ventures continue to be vague. Therefore, this study aims to clarify the concept of social ventures as part of the Fourth Sector, and research development strategies for the vitalization of the social venture ecosystem in an effort to encourage inclusive growth of society. To achieve these goals, it establishes the concept of social ventures differentiated from the Third Sector, based on previous studies, and presents the importance of an intermediate support organization for the ecosystem's vitalization. Furthermore, to propose strategies for said vitalization, the study derives detailed forms of social venture intermediate support organizations, and provides suggestions regarding their importance and roles through social innovation levels.

Leading Lights and Sector Lights provide a navigable channel, heading reference and a visual indication. Mariners can take easily a reference bearing or line of position. The Busan North Port needed to install a sector light to resolve blind sections because of Busan Port Redevelopment Project D-1 Block Construction Plan. And also the busan new port needed to install a sector light to give safety indication because navigation conditions will be changed due to removal of the to-island. For this reason, design development was made for installation of sector lights. In addition, the results of design development were compared with the AtoN simulation and verified. This paper is expected to be very useful for installing Sector Lights to guide the vessel to port safely in Korea.
