The Deep-sea miner system is composed of body, actuators, sensors, and devices for control and monitoring. At present, we are manufacturing the miner's body included actuators and already consisted with off-the-shelf embedded controller. But sensors and those devices were just determined. To previously test performance of embedded controller which manages control and monitoring of miner system, its simulator must be developed for control and monitoring. Hardware-In-the-Loop(HIL) simulation is being increasingly used in industrial applications. This is an effective tool for the evaluation of electric system and drives. In the HIL simulator, we can test and design the control and monitoring system freely without the risk of hardware ruins and the load of expenses. Also the programming software for miner operating is verified on the HIL simulator. In this paper, we introduce the concept of HIL simulator for control and monitoring of deep-sea miner.

The present study aims to monitor three of the community empowerment projects implemented as part of the community central revitalization projects in Yeongwol. We used an established indicator (i.e., quantitative evaluation) as well as an interview (i.e., qualitative evaluation) throughout the monitoring process. The PM (project manager) committee members, consisting of six interdisciplinary experts, carried out the monitoring from $24^{th}$ of October until the $26^{th}$ of November 2018. We categorized the results of the monitoring into the aspects of needs, software, and hardware, and analyzed them as follows: First, although the locals were willing to take part in programs, they were in overall not well informed about the ongoing programs and the program that suits their needs the most. The service organization should therefore actively publicize the program and provide sufficient information about it .Second, instead of a one-off program, the locals should be empowered to take over the program eventually and develop it as a local business model. Last, the locals from the center as well as the outskirts of Yeongwol should organize a learning net, collaboratively develop a further program, and assess its effectiveness by employing a thorough monitoring system.

Objectives: This study was aimed to share the development process of the critical pathway (CP) for the treatment and management of stroke patients admitted to a Korean medicine hospital. Methods: A draft CP was prepared based on a review of relevant literature and medical records in the hospital, and its validity was reviewed by the in-hospital CP review committee. Each member evaluated all items in the CP on a 5-point Likert scale. Items with an average score of 3.5 or higher or an agreement rate of more than 80% were considered valid. In addition, free described opinions to improve the CP were also received from the review committee. Results: The horizontal axis of the CP was composed of a time domain, including 7 time points from hospitalization to discharge. The vertical axis was composed of 9 domains of medical practice. All items in the CP satisfied the validity criteria. The CP was revised, supplemented, and completed by reflecting the opinions of the committee. Conclusions: This CP will be taught to in-hospital users and will continue to be used with regular monitoring and a feedback plan. This study is expected to serve as a useful reference for standardizing the treatment process and delivering measures to improve the adequacy of Korean medicine treatment for stroke patients.

This study examines the impact of female representation on board of directors and audit committees on financial reporting quality, which also discusses the moderating role of family ownership in female representation on boards of directors and audit committees and financial reporting quality. The unbalanced panel is made up of 271 non-financial companies listed on the Pakistan Stock Exchange (PSX) from 2008 to 2019.The findings reveal that female representation on the board of directors has a large and negative impact on financial reporting, but female representation on the audit committee has a significant positive impact on financial reporting quality. Furthermore, the results reveal that family ownership has a negative impact on the relationship between female presence on boards of directors and financial reporting quality. Furthermore, the findings show that family ownership reduces the impact of female involvement in audit committees on the quality of financial reporting. However, family ownership has no direct impact on financial reporting quality.Our findings suggest that selecting females to serve on boards of directors and audit committees should be based on specific criteria (e.g., monitoring abilities, business competence, knowledge, and experience) rather than on family relationships.

In this paper the recent research and application activities on smart structure technologies for civil infra structures in Korea are briefly introduced. The developments of structural health monitoring systems and effective retrofit/maintenance methodologies for infra structures have become active in Korea since the middle of 1990's, as the number of the deteriorated infra structures, mostly built on the rapidly industrialized period of 1970's, has increased very rapidly. Discussions are made on smart sensors, non destructive technologies, monitoring and assessment methods and systems for civil infra structures.

Global land related datasets such as land use, land cover, vegetation cover percentage, forest cover percentage, are part of important global geospatial environmental datasets for global change studies. Since land cover varies place by place, continental production of dataset is a usual approach. Western academically developed countries have some projects to describe land cover related information in digital form using remote sensing technology in African, American continent and Oceania. In this paper, the author introduce his initiative to coordinate Asian scientists in order to develop land related dataset of Asia for our better understanding of the environment of Asia and for contribution to the development of global dataset. This paper explains activities by Land Cover Working Group (LCWG) of the Asian Association on Remote Sensing(AARS), Data and Information System(DIS) sub-committee of Japan national committee for the International Geosphere and Biosphere Program(IGBP), and the International Society for Photogrammetry and Remote Sensing(ISPRS) Working Group IV/6 on Global databases supporting environmental monitoring.

This paper addresses a methodology for monitoring the first phase('92-94') progress and its implication fo Highly Advanced National R&D Projects (HAN or G7 project) in Korea. The authors suggest a three-stage life cycle model for the management of national R&D program; planning stage, implementing & monitoring stage, and evaluating & harvesting stage. The interim evaluation, the main focuses of this paper, is one of the key issues for the effective management of national R&D program at the implementing & monitoring stage. The conceptual framework of the interim evaluation was developed both through reviewing related literature and considering the characteristics of the HAN program. A stepwise procedure of interim evaluation was introduced: 'initial screen' and 'detailed examination'. At initial screen all 11 projects were reviewed in terms of both their relevance and performance in order to decide whether further detailed scrutiny is needed or not. If there exist critical problems on the relevance or on the intermediate progress of each project, it is to be under further detailed examination. Evaluation was initiated by the G7 Planning and Evaluation Committee, which was established for advising, directing, and monitoring the HAN Projects, with the help of large number of experts from industries, universities, and research institutes. The monitoring results were reported to the related ministries and project coordinating agencies, and reflected in the second phase.

Viet Nam is a country with the highest rate of adult male smokers in the world. In 2010, the percentage of adult male smokers was 47.4%. Each year in Viet Nam, there are 40,000 lives lost from tobacco-related diseases. The Global Tobacco Youth Survey is an international standardized survey that has been conducted in more than 140 countries. To provide evidence for tobacco control, Viet Nam already conducted two rounds of GYTS in 2003 and 2007. The GYTS in 2014 is the survey's third iteration. This paper aims to document key methodological details and socio-demographic characteristics of the respondents included in the 2014 GYTS in Viet Nam. This survey followed international protocol and was conducted in 13 provinces representative of 6 geographical regions. A total of 3,430 school children, aged 13 to 15 years used a standardized answer sheet to answer 76 questions about seven tobacco-related topics, including prevalence of tobacco use, environmental tobacco smoke, access and availability, media and advertisement, cessation, knowledge and attitudes, tobacco-related school curriculum. This GYTS provides valid and reliable data for monitoring tobacco use among youth in Vietnam and is recommended to be regularly repeated.

Stream Pilot Project, which began in May 2003 and finished in December 2003, was selected to develop effective methods applicable to nature-like streams. Stream restoration projects aim to maintain or increase ecosystem goods and services while protecting downstream and coastal ecosystems. Fields environmental monitoring such as flow discharge and precipitation were conducted along the Idong stream for amount of channel zone change in 2007. This study selected three monitoring positions to measure the water level and discharge of flowing water. A stage-discharge relation is obtained from direct discharge measurements for three stations by fitting an empirical relationship to the data set. Since discharge measures are made only for low flow conditions, a curve of discharge against stage can then be built by fitting these data with a power curve. And this study used data obtained from floodmark checkup as well as HEC-RAS model to analyze the hydrodynamic characteristics of monitoring sites. Reach-averaged hydraulic parameters for the supply reach were calculated from the small area's HEC-RAS model for Idong stream, and a HEC-RAS model used to analyze hydraulics for a period in 2007, after the stream was considered bank stabilization.
