In Hansan Geojeman area, 2,050 ha of shellfish growing area has been designated as shellfish production area for export. The main shellfish species from the designated area is oysters. For the sanitary management of the designated area established in Hansan Geojeman area, bacteriological examination of sea water and shellfish at the sampling stations inside and outside of the designated area were performed from January 2006 to December 2008. The range of fecal coliform of 756 sea water samples at 21 stations located in the designated area were <1.8~>1,600 MPN/100mL. And the range of geometric mean and the estimated 90th percentile of fecal coliform were 1.8~2.9 and 2.7~15.8 MPN/100mL, respectively. Sanitary conditions of the current designated area in Hansan Geojeman meets the required standards of the Fisheries Product Quality Control and National Shellfish Sanitation Program (NSSP, USA) criteria for the approved area. Also, the sanitary status of the shellfish harvested from the designated area met the Korean Shellfish Sanitation Program (KSSP) fecal coliform criterion (<230 MPN/100g). And the human pathogen such as Salmonella spp. and Shigella spp. were not detected from the examined shellfish samples.

A suitable monitoring method is necessary for successful policy implementation and its evaluation, required for effective prevention of abnormal fire occurrences. To do this, there were studies for applying control charts of quality management to fire occurrence monitoring. As a result, it was proved that more fire occurs in winter and its trend moves yearly-basis with some patterns. Although it has trend, if we apply the same criteria for each time, inefficient overreacting fire prevention policy will be accomplished in winter, and deficient policy will be accomplished in summer. Thus, applying different control limits adaptively for each time would enable better forecasting and monitoring of fire occurrences. In this study, we treat fire occurrences as time series model and propose a method for configuring its coefficients with ARIMA model. Based on this, we expect to carry out advanced analysis of fire occurrences and reasonable implementation of prevention activities.

Objectives: This study was performed to analyze the interventions of Oriental Medicine which had been commonly used for postpartum disease and postpartum care. Methods: We searched research on the interventions for postpartum disease and postpartum care in 4 domestic search engines. After that, we conducted eligibility screening based on inclusion and exclusion criteria. Results: 1. We selected total 50 studies. There were 2 randomized controlled trial (RCT), 5 non-RCT, 35 case reports, 8 case series within the 6~8 weeks after childbirth. 2. Of the 35 case reports, several interventions were used : acupuncture (22), moxibustion (11), cupping therapy (7), pharmacopuncture (5), chuna manipulation (4), herbal medicine (34). The most common symptoms were musculoskeletal symptoms (8), followed by postpartum depression (7). Various prescriptions and acupoints of oriental medicine were used depending on the diseases or symptoms. 3. Of the 8 case series, 382 subjects in 5 case series had taken Saenghwa-tang-gagam. And Acupuncture, moxibustion, cupping therapy (5), pharmacopuncture (1) were used as an intervention. 4. The most commonly used acupoint is 腎兪 (BL23) in the pain including postpartum back pain and 三陰交 (SP6), 關元 (CV4) in the postpartum care. 關元 (CV4) is the most commomly used moxibustion point not only the postpartum disease but also the postpartum care. Conclusions: In clinical studies of oriental medicine related to postpartum disease and postpartum care, pain-related clinical studies that belong to or progress to Sanhupung were the most common (30%), and among them, postpartum low back pain studies were the most common (20%). Based on this, we believe that large-scale clinical studies with high quality using oriental interventions including chuna and pharmacopuncture are needed to establish guidelines for the management of pain treatment including postpartum back pain.

Algae are an important component of the ecosystem. However, the excessive growth of cyanobacteria has various harmful effects on river environments, and diatoms affect the management of water supply processes. Algal monitoring is essential for sustainable and efficient algae management. In this study, an object detection model was developed that detects and classifies images of four types of harmful cyanobacteria used for the criteria of the algae alert system, and one diatom, Synedra sp.. You Only Look Once(YOLO) v8, the latest version of the YOLO model, was used for the development of the model. The mean average precision (mAP) of the base model was analyzed as 64.4. Five models were created to increase the diversity of the input images used for model training by performing rotation, magnification, and reduction of original images. Changes in model performance were compared according to the composition of the input images. As a result of the analysis, the model that applied rotation, magnification, and reduction showed the best performance with mAP 86.5. The mAP of the model that only used image rotation, combined rotation and magnification, and combined image rotation and reduction were analyzed as 85.3, 82.3, and 83.8, respectively.

The purpose of this study is to investigate the teacher-students interactions shown in the images of elementary science class by preservice teachers. We applied nine analysis criteria in three domains such as emotional support (climate, regard for student perspectives, teacher sensitivity), classroom organization (instructional learning formats, behavior management, productivity), and instructional support (quality of feedback, language modeling, concept development) in the aspects of positive or negative interactions The results show that majority of student-teachers tended to prefer positive interactions especially regarding instructional learning formats or concept development. For the image of avoided class, they tended to show negative interactions related to instructional learning formats or regard for student perspectives. However, they showed extremely lower frequencies for some categories of negative interactions. Female preservice teachers tended to have slightly higher frequencies for some positive interactions than their counterpart. The findings indicate possible approaches to teachers' professional development and further research.

This study aims to assess the maturity of Korean open access (OA) journals using the OA infrastructure provided by the Korea Institute of Science and Technology Information, and develop necessary strategies for future improvement. The assessment model consists of three dimensions, 12 items, and 24 sub-items. The importance of the three dimensions (A: OA policy establishment and disclosure, B: OA sustainability, and C: Journal openness quality) was differentiated by the Analytic Hierarchy Process, and the maturity stages were divided into five levels (Entry, Growth1, Growth2, Maturity1, and Maturity2). The assessment was carried out twice for 100 academic journals. The results indicated that the proportion of journals at or above the Growth1 level increased by 11% to reach 83% during the second assessment phase, which could be owing to the learnings of the first assessment. Following expert consultations on the assessment results, three support measures were identified to activate OA. The first includes OA promotion and education activities, which involve creating standard regulations and guidelines, and advancing educational activities for societies that are either preparing for or currently implementing OA. The second involves providing support for technical aspects, such as identifiers, XMLization, and copyright management, through peer review and OA publishing platforms. The third includes collaborative activities to enhance journal evaluations and the recognition criteria for researchers' achievements in OA journals, and fostering cooperation with national and research and development institutions for financial support.

The study was conducted to set up the criteria of judgement that could be utilized for cultivated wild ginseng, easy and well-defined for consumers to understand. For the purpose, the study examined consumers' perception and valuation on each attribute of cultivated wild ginseng that was related to the product quality through a choice experiment. Attributes used in the experiment were based on exterior characteristics of cultivated wild ginseng including ages, planting methods, external dimension, length of fibrous roots, and hue and color. Residents in Seoul and Gyeonggi Province were interviewed and a total of 173 questionnaires were acquired for the analysis. According to the result, respondents valued the highest score on ginseng grown by direct sowing, while they valued rather lower scores on ginseng's external dimension. In general, the hypothetical model was shown to exist within the stable range.
