IMO developed VIMSAS for effective application of IMO instruments related to maritime safety and environmental protection and was implemented from 2006 to 2016. Based on this, the purpose and procedures of VIMSAS applied to IMO member states by trial, and IMSAS was enforced from January 1st 2016. IMSAS was implemented to ensure that IMO Member States, such as flag states, coastal states and port states that ratified the IMO Convention, are properly performing their given responsibilities and to ensure the effective implementation of the IMO instruments through the improvement of identified non-conformities. In this study, the auditing contents and procedures were verified based on IMO documents in order to prepare for the IMSAS audit of Republic of Korea scheduled for 2020. For this purpose, this study proposed an update of a directory, development of monitoring system for information reporting required by IMO instruments, designation of relevant experts, preparation of an English version of related national laws, training of IMSAS auditors and establishment of an IMSAS audit response team for audit of IMSAS in 2020 by referring to the results of the VIMSAS for Republic of Korea, major findings of the VIMSAS of other IMO member states, and Consolidated Audit Summary Report (CASR), which was submitted at the 5th IMO III sub-committee.

Objective: The objective of this study was to explore the knowledge and perceptions of Malaysian tradition healers towards cancer and cancer prevention. Methodology: A total of 25 participants agreed to participate in this qualitative study during the period from $20^{th}$ July 2011 until $24^{th}$ of September 2011. The proposal of this study was approved by the Ethics Committee of Management and Science University (MSU). Once the participant agreed to be interviewed, date, time and place of the interviews were determined. Consent form was obtained from participants before the interview began. Participants were briefed about the study and its purpose, and after asking their permissions, their replies were recorded. The data was organized into themes and analyzed manually. Results: Twenty-five Malaysian traditional healers participated in this qualitative study. The age of participants ranged between 26 to 78 years old. The majority were in the age group of 31-60 years old, male, Chinese, degree holders with a monthly income ranging from 1,000-5,000 Ringgit Malaysia (RM) and were married (56%, 80%, 48%, 52%, 68%, 84% respectively). The majority defined cancer as having high cholesterol or abscess accumulation. A few of them defined cancer as a type of cell growth. The majority mentioned that food and unhealthy lifestyles are the primary causes of cancer. Surprisingly some of them mentioned that cancer is caused by interference by ghosts. Regarding the diagnosis of cancer, the majority mentioned that they refer their patients to modern physicians' medical report when it comes to diagnosing or treating patients with cancer. The most common cancers that many patients came to seek treatment were breast cancers, followed by colon cancers, liver and lung cancers. Conclusions: Despite good knowledgeabout the causes of cancer among traditional healers, misconceptions still exist. Insufficient knowledge about the definition of cancer was noted among the traditional healers. This urges immediate action by the Ministry of Health of Malaysia to set up a strict regulation and regular monitoring of the traditional healers nationally. Traditional and Complementary Medicine may be integrated into the healthcare system and need to have sustained cooperation for the benefit of patients since about 80% of patients use traditional medicines.

Purpose: This study was done to investigate the status of disinfection and sterilization in healthcare facilities. Method: A survey of 193 Korean healthcare facilities was conducted from February 8 to March 7, 2013. Data were analyzed using descriptive statistics, ${\chi}^2$ test, Fisher's exact test, one-way ANOVA, Scheffe with SPSS WIN 18.0. Results: Of the healthcare facilities 93.2% had specific guidelines for disinfection/sterilization, but only 47.9% had a committee on disinfection/sterilization for decision-making, less than half (42.7%) conducted regular monitoring of actual practices, while 83.9% had established procedures for recovery in case of problems with the disinfection process and 89.0% kept records and archives of disinfection practices. Cleaning process, selection of chemical disinfectants and process of disinfection and sterilization were found to be inadequate in some healthcare facilities. Perception score for adequacy of medical instruments was 8.10, environmental disinfection was 7.20, and sterilizer management was 8.45 out of a possible 10. Conclusion: Compared to larger institutions, smaller healthcare facilities had less effective disinfection and sterilization management systems, while some facilities showed inadequate practices for medical equipment and general sterilization. Better academic and state-level support is recommended for smaller facilities in order to establish a better system-wide management system.

As a series of fundamental researches on the development of an automatic identification monitoring system for fishing gear. Firstly, the study on the installation method of automated identification buoy for the coastal improvement net fishing net with many loss problems on the west coast was carried out. Secondly, the study was conducted find out how to install an automatic identification buoy for coastal gill net which has the highest loss rate among the fisheries. GPS for fishing was used six times in the coastal waters around Seogwipo city in Jeju Island to determine the developmental status and underwater behavior to conduct a field survey. Next, a questionnaire was administered in parallel on the type of loss and the quantity and location of fishing gear to be developed and the water transmitter. In the field experiment, the data collection was possible from a minimum of 13 hours, ten minutes to a maximum of 20 hours and ten minutes using GPS, identifying the development status and underwater behavior of the coastal gillnet fishing gear. The result of the survey showed that the loss of coastal net fishing gear was in the following order: net (27.3%), full fishing gear (24.2%), buoys, and anchors (18.2%). The causes were active algae (50.0%), fish catches (33.3%) and natural disasters (12.5%). To solve this problem, the installation method is to attach one and two electronic buoys to top of each end of the fishing gear, and one underwater transmitter at both ends of the float line connected to the anchor. By identifying and managing abnormal conditions such as damage or loss of fishing gear due to external factors such as potent algae and cutting of fishing gear, loss of fishing gear can be reduced. If the lost fishing gear is found, it will be efficiently collected.

The present study was carried out in order to assess the dietary exposure as well as the risk for lead (Pb) and cadmium (Cd) exposure through mushrooms among the Korean population. Various samples (n=536) covering 17 kinds of mushrooms were collected from retail outlets and markets in Korea. The contents of Pb were 0.005 (King oyster)-0.026 (Matsutake) mg/kg in raw mushrooms and 0.014 (Oyster)-16.411 (Manna lichen) mg/kg in dry mushrooms, respectively. The contents of Cd were 0.002 (Enoki)-0.205 (Hericium erinaciium) mg/kg in raw mushrooms and 0.021 (Vegetable worms)-2.650 (Agaricus blazei Muill) mg/kg in dry mushrooms, respectively. The mean dietary exposure of Pb for the general population was $0.053{\mu}g/day$, taking 0.03% of provisional tolerable weekly intake (PTWI). The mean dietary exposure of Cd for the general population was $0.168{\mu}g/day$, corresponding to 0.37% of provisional tolerable monthly intake (PTMI). Therefore, the level of the overall dietary exposure to heavy metals through mushroom for the Korean population was far below the recommended JECFA levels, indicating little possibility of concern.

This paper analyzes empirically how analysts' forecasts affected by ownership structure. This study examine a sample of 1,037~1,629 the analysts' forecasts of firms registered in Korean Stock Exchange in the period from 2000 to 2006. The empirical results are summarized as follows. First, from the analysis, companies which have higher major shareholder's holdings tend to increase earnings forecast errors and earnings forecast accuracy. Meanwhile, companies which have higher institution shareholder's holdings tend to decrease earnings forecast errors and earnings forecast accuracy. This result is in line with the view of previous works that companies with higher major shareholder's holdings look towards more of analysts' optimistic forecasts in order to maintain friendly relations with major shareholders. Because of analysts' private information use from major shareholders, earnings forecast accuracy is higher in high major shareholder's holdings firm than in high institution shareholder's holdings it. Second, this analysis is whether the minimal required selection condition of outside directors, audit committee adoption and audit quality affect the relation between ownership structure and analysts' forecasts. This result is that variables related corporate governance do not affect statically the relation between ownership structure and analysts' forecasts. The meanings of this paper is to suggest the positive relations between ownership structure and analysts' forecasts. After this, if analysts will notice forecasts of more many firms, capital market will be more efficient and this field works are plentiful. Also it will need monitoring systems not to distort market efficiency by analysts' dishonest forecasts.

There is an increasing concern over arsenic (As) contamination of paddy soil and rice with regard to food safety. This study was conducted to investigate total and inorganic As concentration in one hundred husked and polished rice samples collected at the non-contaminated paddy soil in Korea. Arsenic species in rice samples were extracted using 1% nitric acid ($HNO_3$) with a microwave oven and were measured using high performance liquid chromatography coupled with inductively coupled plasma-mass spectrometry. Mean concentrations of total As in husked rice and polished rice were 0.18 and $0.11mg\;kg^{-1}$, respectively. Also, average inorganic As concentrations in husked rice and polished rice were 0.11 and $0.07mg\;kg^{-1}$, respectively. These levels are lower than the standard guideline value 0.35 and $0.2mg\;kg^{-1}$ for inorganic As in husked and polished rice recommended by Codex Committee on Contaminants in Foods and Ministry of Food and Drug Safety, respectively. The mean of the inorganic As ratio for the total amount of As was 0.65 and 0.67 for husked rice and polished rice, respectively, and the range was from 0.08 to 1.0. For health risk assessment, the average value of cancer risk probability was $9.24{\times}10^{-5}$ and ranged from $2.30{\times}10^{-5}$ to $1.90{\times}10^{-5}$. Therefore, human exposure to As through dietary intake of surveyed rice samples might considered to be a low health risk.

In 2021, the Joint Group of Experts on the Scientific Aspects of Marine Environmental Protection (GESAMP), a U.N. advisory research institute, cited container loss as one of six sources of marine litters in shipping. The sinking of the X-P ress Pearl in May 2021 caused a catastrophic environmental pollution accident in which the loaded containers were moved to the shore, and the plastic pellets were loaded inside covered the coast of Sri Lanka. With this history, the International Maritime Organization (IMO) will discuss prevention and follow-up measures for container loss during ship voyages, as an agenda at the 8th Sub Committee on Carriage of Cargoes and Containers meeting in September 2022. To establish Korea's response direction at the IMO meeting, this study identified major causes of container loss accidents, and considered the response through analysis based on the accident investigation report and related professional data. As a result, it was found that the major cause of container loss during voyages was the enlargement of container ships, bad weather, and poor loading of containers. In particular, the need to prepare countermeasures for the deterioration of the operational safety of large container ships due to bad weather was identified. Additionally, integrated monitoring of the implementation of international conventions is required, for the safe sea transportation of container cargo. In particular, in terms of preservation of the marine environment, it is necessary to supplement the system for the recovery of lost containers. Finally, it was found that it is necessary to establish systems that can complement each other in the shipbuilding and shipping industries, in terms of shipbuilding as well as ship operation, to fundamentally prevent container loss accidents at sea. It is judged that it is difficult to resolve the various factors of container loss at sea during voyages, by responding from an individual perspective.

Shellfish are exoskeleton-bearing aquatic invertebrates that consume various organic and inorganic substances floating in seawater through filter feeding. Heavy metals are known as absorbed and accumulated in seawater. Some of the toxic heavy metals are highly accumulated in seawater, and exposure to them can cause a variety of risks to the human body. Since Koreans like to eat seafood, they are more likely to be exposed to contaminated seafood with heavy metals. In this study, nine types of heavy metals were analyzed on ten different shellfish species in the coastal area of South Korea. The risk assessment was also done on shellfish in which heavy metals were detected. Zinc (Zn) and copper (Cu) were identified at an average of 56.7 mg/kg (6.70 to 466 mg/kg) and 13.2 mg/kg (0.064 to 143 mg/kg), respectively. Lead (Pb) average of 0.208 mg/kg (0.000750 to 1.02 mg/kg), cadmium (Cd) average of 0.454 mg/kg (0.0388 to 1.56 mg/kg) and mercury (Hg) average of 0.0266 mg/kg (0.00548 to 0.174 mg/kg) were identified. Additionally, arsenic (As), chromium (Cr), nickel (Ni), and silver (Ag) were also identified as average concentrations of 4.02 (0.460 to 15.0 mg/kg), 0.167 (< limit of quantification [LOQ] to 0.820 mg/kg), 0.281 (< LOQ to 1.46 mg/kg), and 0.158 mg/kg (< LOQ to 1.15 mg/kg). The result indicates that the monitoring results of heavy metals in most shellfish satisfied the Korean standard. However, Pb and Cd have exceeded some foreign standards, such as the United States and the EU. The permissible human exposure calculated using the heavy metal intake and detection amount was lower than the Joint FAO/WHO Expert Committee on Food Additives human safety standard, and the risk of heavy metals from shellfish consumption was at an acceptable level.

Recent abnormal climate conditions have increased the risk of slope collapses, which frequently result in significant loss of life and property due to the absence of early prediction and warning dissemination. In this paper, we develop a slope condition analysis system using IoT sensors and AI-based camera to assess the condition of slopes. To develop the system, we conducted hardware and firmware design for measurement sensors considering the ground conditions of slopes, designed AI-based image analysis algorithms, and developed prediction and warning solutions and systems. We aimed to minimize errors in sensor data through the integration of IoT sensor data and AI camera image analysis, ultimately enhancing the reliability of the data. Additionally, we evaluated the accuracy (reliability) by applying it to actual slopes. As a result, sensor measurement errors were maintained within 0.1°, and the data transmission rate exceeded 95%. Moreover, the AI-based image analysis system demonstrated nighttime partial recognition rates of over 99%, indicating excellent performance even in low-light conditions. Through this research, it is anticipated that the analysis of slope conditions and smart maintenance management in various fields of Social Overhead Capital (SOC) facilities can be applied.
