GOCI-II, succeeding the mission of GOCI, was launched in February 2020 and has been in regular operation since October 2020. Korea Institute of Ocean Science and Technology (KIOST) processes and produces in real time Level-1B and 26 Level-2 outputs, which then are provided by Korea Hydrographic and Oceanographic Agency (KHOA). We introduced current status of regular GOCI-II operation and showed future improvement. Basic GOCI-II products including chlorophyll-a, total suspended materials, and colored dissolved organic matter concentration, are induced by OC4 and YOC algorithms, which were described in detail. For the full disk (FD), imaging schedule was established considering solar zenith angle and sun glint during the in-orbital test, but improved by further considering satellite zenith angle. The number of slots satisfying the condition 'Best Ocean' significantly increased from 15 to 78. GOCI-II calibration requirements were presented based on that by European Space Agency (ESA) and candidate fixed locations for calibrating local observation area were. The quality management of FD uses research ships and overseas bases of KIOST, but it is necessary to establish an international calibration/validation network. These results are expected to enhance the understanding of users for output processing and help establish detailed plans for future quality management tasks.

The schools in the survey consisted of 61 schools where foodservice was managed by themselves and 49 schools where it was done cooperatively. According to the style managed, the urban style was 42 schools, the rural style was 46, and the island style was 22. With regard to the amount for each student that parents have to pay. it was 745 won at schools managed by themselves and 616 won at schools managed cooperatively. The budgeted amount was 75 won at schools managed by themselves and 97 won at schools managed cooperatively. The result showed that parents at schools managed for themselves paid much more for the cost of food and management. The mean area of kitchens was 31 pyong (102 sq. meters) in environment of cooking utilities, and management was done wherever they were needed. The budgeted amount was supplied from the Educational Office and parents. In the situation of utilities and instruments for cooking, the places to wash hands and flush toilets, which were regarded as sanitary facilities were insufficient. The rates of containing measuring instruments and thermometers for cooking were also insufficient. The list to be considered in the management of menu was concentrated on raising acceptance of students served, based on the order of the tastes of students served, the quantity of the cost, nutrition needed, and then facilities. The replies that leftover food was thrown away after meals were numerous and the rate of leftover food was reflected on the menu. In purchase and management, the rate of food needed to be purchased was calculated through experience. A private contract was chosen to purchase food. The frequency of purchasing food was usually once a day, which would nutritists examined food, concentrating on the order of quality, number, and price. In the management of operation, a schedule for making food was seldom formed, referring to it only at the time needed. All the food was made in a day but some special foods were made the day before they would be required. It shows the situation was thought to be the most important. Guidance for sanitation was carried out once a month and the content of the guidance was about the sanitary treatment of food. With regard to degree of satisfaction with the management of meal service, all the dietitian at schools managed for themselves and cooperatively were somewhat satisfied with all the questions about the budgeted amount of food, and management, the management of purchase, operation, and sanitation. However, they were not satisfied with the environment of facilities.

A stacking yard of a container terminal is a space for temporarily storing the containers that are carried in or imported until they are carried out or exported. If the containers are stacked in an inappropriate way, the efficiency of operation at the time of loading decreases significantly due to the rehandlings. The remarshaling is the task of rearranging containers during the idle time of transfer crane for the effective loading operations. This paper proposes a method of planning for remarshaling in a yard block of an automated container terminal. Our method conducts a search in two stages. In the first stage, the target stacking configuration is determined in such a way that the throughput of loading is maximized. In the second stage, the crane schedule is determined so that the remarshaling task can be completed as fast as possible in moving the containers from the source configuration to the target configuration. Simulation experiments have been conducted to compare the efficiency of loading operations before and after remarshaling. The results show that our remarshaling plan is really effective in increasing the efficiency of loading operation.

Weeding refers to the process of removing weeds around crop trees, which cause competition in nutrients, moisture, and light, and has a great effect on the early growth and survival of crop trees for establishing forest resources. This study was conducted to find out the timing and method of weeding that is the most suitable for the major afforestation species in national forests. We investigated (1) weeding time and frequency for each afforestation species and (2) the height of crop trees and the length of weeds. Up to 99% weeding operation was carried out until 5 years following afforestation. Pinus densiflora, Larix kaempferi, Chamaecyparis obtusa, Prunus sargentii, and Betula platyphylla plantations accounted for more than 70% of the total weeding sites. Once-a-year weeding process was conducted from late June to late July (67%), and twice-a-year weeding process was the highest in June-August by 31%. Most species were shorter than the weeds until the first and second year of planting, but the height of the crop trees was higher than that of the weeds by 48% in average from the third year. Therefore, from the third year of afforestation, except for some species, it is possible to reduce the cost of weeding operations while reducing nutrient competition by the weeds through the removal of weed sprouts, mainly woody weeds, rather than clear cutting. This study contributes to efficiently develop forest resource establishment while reducing operational costs through a detailed weeding schedule and species-specific method.

The Seaborne Trade Volume accounts for 97% of the total. This means that the port operation management system can improve port efficiency, reducing operating costs, and the manager who manages all operations at the port needs to check and respond quickly when delays of work and equipment support is needed. Based on the real-time location information confirmation of yard automation equipment used the existing system GPS, the real-time location information confirmation system is a GPS system of the tablet, rather than a port operation system that monitors location information for the entered information, depending on the completion of the task or the start of the task. Network configurations also reduce container processing delays by using commercial LTE services that do not have shading due to containers in the yard also reduce container processing delays. Trough introduction of smart devices using Android or IOS and container processing scheduling utilizing artificial intelligence, we will build a minimum delay system with Smart Device usage of container processing applications and optimization of container processing schedule. The adoption of smart devices and the minimization of container processing delays utilizing artificial intelligence are expected to improve the quality of port services by confirming the processing containers in real time to consumers who are container information demanders.

Advanced surgical technology demands more precise, meticulous, and time-consuming procedures. In addition, the patient's preference of tertiary health providers makes over crowding of the University Hospitals. Therefore, it has been necessary to maximize utilization of the operating room of such hospitals to accommodate these requirements. This study, targeting 1,302 surgical cases performed in 22 operating rooms at a university hospital in Seoul from October 8 to November 1, 2001, analyzed reasons for delay, and factors that caused delayed use of operating rooms. This study also assessed that the rate of operating room use would increase if the sources for possible reform were improved. 1. Among total of 1,302 cases of surgery, the incidence of surgeries in which there were no time delays and no factors for delay were discovered is 71.4% or 930 cases: the incidence in which surgeries were delayed was 28.6% or 372 cases. 2. As results of logistic regression for delay, procedures involving women were delayed 1.4 times more frequently than those of men. Compared to Department A, Department B was 1.8 times more likely to be delayed, and Department H was 0.4 times less likely to be delayed. Regional anesthesia was 2.4 times more likely to be delayed than general anesthesia, and surgeries that PCA was applied were 0.6 times less likely to be delayed than those when it was not. Surgeries performed on the Thursday were 1.7 times more likely to be delayed than those performed on the Monday. Compared to surgeries performed between 07:00-07:59, those performed between 08:00-08:29 were 4.3 times higher. 3. The reasons for delay were related to surgeon, surgical department, patient, anesthesia, administrative system, sick ward, and support services. Among these, 5,755 minutes for 276 delayed cases could be resolved easily, and resolving delays of 3,320 minutes for 131 cases would be more difficult. Among the causes for delay that could be improved, delays due to patient's transfer and surgeon's factor were the most common, 21.6% and 17.4% respectively. 4. If resolvable delays are improved, pre-anesthesia room is administered, and regional anesthesia and PCA are done ahead of time, use of emergency operating rooms will increase, we can increase overall utilization by 4.09%, we will save 744 minutes a day, we can reduce the time the operation room is used after 4 PM by 35%, and we can resolve the operation cancellations due to insufficient operating rooms. For the increase in the use of operating rooms, we need to maximally decrease the delays that could be improved, by allocating block time based on used totals hours of elective cases, giving accurate information on surgery schedule, voluntary cooperation by staff participating in surgeries in reducing delay time, and the hospital management's will to improve delay.

If an underground accident occurs, the cause must be quickly identified and human and material damage reduced. The Underground Accident Investigation Committee is responsible for identifying the causes of accidents and preparing response plans to prevent similar accidents from occurring in the future. The law stipulates that the Underground Accident Investigation Committee can operate from a minimum of 6 months to a maximum of 9 months after an accident occurs. However, the operation schedule of the Underground Accident Investigation Committee seems difficult to cite the accident investigation report to the construction project currently in progress at the same time project. In this study, the Underground Accident Investigation Committee seeks to establish a strategy for developing technology that can shorten data collection and analysis, which previously took 3 months, to less than 1 month. As a result of the research, five areas of technology development identified, ground data collection and transmission technology, ground safety data generation technology, digital twin-based underground safety analysis and visualization technology, digital twin-based geo-ambulance construction and operation technology, and digital twin-based geo-ambulance standardization and legal system. research was able to be conducted. If the proposed technology is developed, it is expected to contribute to reducing accident scenes through faster decision making than before.

This Study was an attempt to estimate the optimum numbers of Operating Room Nursing Manpower by measuring the amount of service hours required by the patients in Operating Room in relation to the service amount actually provided by the nurses. The major concern of this study was placed on the measurement of Nursing Service Requirements by using the Operating Room (O. R) Patient Acuity System recently developed by M. M. Hart to classify the O. R. patients into four groups according to the degree of the complexity of operative procedure and some other elements which increase nursing activities in respect of patient care; Acuity IV group is the one requires nursing services most, on the other hand Acuity I requires least. nu sing The objectives of this study were as follows; 1. To analyze functions of the nursing personnel in O. R. by time unit and to estimate the average time a nurse can activate for productive functions. 2. To measure the actual amount of nursing times provided by nurses to the surgical patients. 3. To develop a patient classification system in order to measure the amount of Nursing services required by the patients. 4. To calculate an appropriate number of nursing manpower to meet the needs of the patients. In order to conduct the research both selected nurses and patients in 'S' University Hospital were Studied by utilizing the O. R. Patient Acuity System as well as the Classification Chart developed by Association of Operating Room Nurses (A. O. R. N) as a means of classifying functions of O. R. nurses. That is; Functions of the 10 selected O. R. nurses observed during the period of June 30 to July 4, 1986, whereas the amount of nursing services required by or provided to the 974 patients who had received surgeries during the period of June 9 to July 4, 1986. The results of this study were as follows; 1) The actual working hours per a nurse averaged 6.7 hours a day. 2) Each nurse's daily routine schedule consists of $71.4\%$ for Technical Functions, $16.1\%$ for Nonprodective Functions, $6.6\%$ for Assessment and Evaluation, $3.9\%$ for Overseeing and Supervision and the rest $2.0\%$ for Patient Preparation respectively. 3) Preoperative waiting time per a patient was 24.1 minutes on the average; for the first case was 10.7 minutes, whereas for the following cases was 32.0 minutes. 4) Total Operation time for the 974 patients during the period of observation for this study amounted to 2759.6 hours, weekly hour was equivalent to 689.9 hours, Whereas daily operation time averaged 130 hours. Meanwhile the average operation time per patient was 2.8 hours ; for the case of Acuity IV was 5.6 hours, 5. 1 hours for the case of Acuity III, 2.3 hours for Acuity II and 1.1 hours for Acuity I. 5) According to the O. R. Patient Acuity System, $64.5\%$ of the whole patients belonged to Acuity II, $23.7\%$ to Acuity III, 11. $3\%$ to Acuity IV and $0.7\%$ to Acuity I respectively. 6) Required amount of nursing times based on the preoperative waiting time and operation time was 7167.8 person hours, which showed that $5.5\%$ of them needed for preoperative nursing care, whereas the rest $94.5\%$ for intraoperative nursing care. In terms of the O. R. Patient Acuity System, $49.7\%$ of total nursing service requirements was needed for Acuity II patients, $27.4\%$ for Acuity III patients, $17.2\%$ for Acuity IV patients and $0.2\%$ for Acuity I patients. 7) The rate of the nursing services provided against the required nursing times was about $81.4\%$ on the average; some departments, like those of Plastic Surgery, Otolaryngology and Ophthalmology whose patients mostly belonged to Acuity II recorded hegher provision rate than average, whereas other departments of Thoracic Surgery. Neurosurgery and Orthopedic Surgery whose patients belonged to Acuity III and Acuity IV as well as Acuity II recorded lower provision rate than average. 8) Subsequently, required numbers of nursing manpower was 10.7 nurses additionally. Based on the above findings the following recommendations will be made; 1) this study recommends, develops. and adopts an accurate and realistic O. R. Patient Acuity System which can help measure the nursing service requirements objectively to elicit the rationales of allocation of nursing personnels. 2) this study proposes storongly place nurses who take the role of preoperative nursing care exclusively for the waiting patients in O. R. and shortening their waiting time by close communication between the designated O. R. and the ward.

Buddhism was introduced in the Korea Peninsula 1600 years ago, and now there are over 10 million believers in Korea. The systematic Management of Temple Records has a spiritual and cultural value in a rapidly changing modern society. This study proposes a better management system of Buddhist temple records for the Jogye Order of Korean Buddhism. this system Not only supports transparency of religious affairs, but presents a way for a more effective management. in this study, I conducted a study on the national legislation for the preservation of buddhist temples and the local rules of religious affairs from the Jogye Order. Through this, I analyzed the problems of Buddhist records management. in the long term, to improve these problems, I purpose the establishment of temple archives be maintained by parish head offices. This study presents a retention schedule for this systematic establishment system. I present charts for the standard Buddhist records management that manage the total process systematically from the production of records to its discard. Also I present a general plan to prevent random defamation of Buddhist temple documents and impose a duty for preservation. I intend for this plan to be subject to discussion and tailored to the particular needs of temple reads. In creating these charts standard of Buddhist temple records management, I analyzed operating examples of foreign religious institutions and examined their retention periods. I also examined the retention periods and classification system from the Jogye Order. Then I presented ways for this management system to operate through computer programs. There is a need to establish a large scale management system to arrange the records of buddhist documents. We must enforce the duty of conserving records through the proposed management system. We need the system to manage even the local parish temple records through the proposed management system and the operation of the proposed archive system. This study presents research to from the basic of the preservation and the passing of traditional records to future generations. I also discovered the historical cultural and social value that these records contain. Systematically confirmed Buddhist temple records management will pave the way that these tangible and intangible cultural records handed down from history can be the cultural heritages. establishing a temple records management system will pave the way for these cultural records to be handed down to future generations as cultural heritages.

Purpose: Recognize circulation work system and fixing work system's merits and demerits that is enforced in operation of PET/CT center in sudden increase recently. Wish to estimate connectivity degree of individual exposure dose and PET/CT working that is managed periodically through this and look for operation efficiency of PET/CT center. Materials and Methods: (1) Find interrelationship of length of service to be individual exposure dose and PET/CT through TLD interpretation. Specially, evaluate on the basis of data of 2.5 years until 2 quarters 2006~2008 year that show patient increase rapidly the latest. (2) Recognize what countermeasure is evaluating problems happened at circulation work system and fixing work system. Results: Patient examination's number was 14,674 items until 2 quarters 2006~2008 year, and the $^{18}F$-FDG average injection amount was 461.5 MBq. 2 people of 10 radiotechnologist did fixing work PET area and GAMMA area each, and 8 people did circulation work of 3 times for 2.5 years. Average exposure dose that PET area and Gamma area's circulation men in service receive was 1.32 mSv, and PET area men in services came out average 0.825 mSv high than Gamma area men in services. Nurse's exposure dose is 0.28 mSv, and next 2 reason is conjectured. One is contact with patient that medicate $^{18}F$-FDG injection, and another is consultation about patient's next time schedule after examination end. Although exposure dose's amount is not much, is expected to consider continuation work possibility by exposure dose in case is a nurse with pregnancy possibility. Also, $^{131}I$-isotope therapy area's radiotechnologist that use capsule appeared by 0.12 mSv and a nuclear medicine doctor appeared by exposure dose that is less of 0.11 mSv. Conclusions: In case do PET/CT center circulation work after a long time, connoted danger that most men in service is consecutiveness deficiency of business and individual exposure dose increase at early 1 month. Specially, way for individual exposure dose's decrease should be considered. Also, need to evaluate abhorrent work form for efficient work system introduction, and enforce circulation and fixing work suggestion suitable shift working. Finally, must make normalized business guide and so on to prevent circulation work people's business efficiency decline.
