Fishing in Kenya, until the discovery of Nile perch as an export commodity in the early 1990s, has basically a subsistence occupation for the lake and coastal communities. The government also did not recognize the importance of fisheries as a contributor to the macro-economy and therefore, did not pay much attention in terms of resource allocation for the development of the sector. Most fishing in Kenya is artisanal, with a little industrial fishing by prawn trawlers. The deep sea (EEZ) fishery resources are currently exploited by DWFNs through a licensing system. Only a small quantity of catch from the EEZ is landed in Kenya, primarily tuna loins for processing for export. Currently capture fisheries, mainly from Lake Victoria, earn local fishers over Kenya shillings (K Sh) 7 billion, while exports earn the country K Sh 5 billion (US$ 50 million) in foreign exchange annually. The government has been putting in place an enabling environment to promote investment activities in order to achieve economic recovery as well as for the development and sustainable use of fisheries resources in the country within the specified period. The Department's major roles are to ensure sustainable exploitation of fisheries resources; to promote aquaculture development; to assure quality and safety of fish and fishery products; and to facilitate fish marketing in order to maximize the benefits that can be derived from fisheries. The contribution of fisheries to local incomes, subsistence and food nutrition is significant, as this occurs in areas with the highest incidences of poverty in the country.

The Korean fishery encountered a difficulty situation, due to the new regime of the Exclusive Economic Zone (EEZ) and the decreasing fisheries resources in Korean waters. In addition, the coastal areas are deteriorated by industrial wastes, sewage, farming wastes and pollution from aquaculture. In this situation, it is necessary to study the TAC (total allowable catch) - based management system, the development of fishing gears and appropriate fishing methods for stock conservation, and the automation system of fishing gears for improving the efficiency of fisheries. The objective of this study is to look for an appropriate system in marine production and resource management under the new UNCLOS (United National Convention for the Law of the Sea) regime for subjects in fishing gears and methods, production system, and information, and fisheries resources management. The results of this study could be used as scientific information to maintain and develop the Korean fisheries and to establish fisheries policy for the management of fisheries resources in Korean waters.

Marine deposition waste threatens the book ecosystem and causes a decrease in catch due to ghost fishing, causing damage of about 370 billion won per year. In order to collect this, a current status survey is conducted using two-way ultrasonic detectors, diving, and lifting frames. However, the scope of the investigation is small to investigate a lot of sedimentary waste, and there is a possibility of causing casualties. This paper deals with the implementation of a high-accuracy marine deposition detection AI model by learning the coastal sediment image data of AI-Hub using the YOLOv5 algorithm suitable for real-time object detection.

Lifestyle of adolescents cause a lot of health effects in the future. Therefore, in Korea, school health law was enacted and relevant business such as school education program is being carried out. This study was conducted to recognize symptom according to grade. A survey of youth health status was conducted at 19 middle and high schools in Seongnam city from May 2015 to December 2015. The survey made up of 14 questions which was about the health status satisfaction on the adolescent was conducted to investigate frequency by year and the respective health status of 6 grades. A total of 9,584 students responded to the survey, 58.22% answered that they were not free of constipation. 25.69% of respondents had no symptoms of headache, consequently over 70% of respondents had headache. 57.06% of respondents had no symptoms of low back pain and 34.7% had no symptoms of neck & shoulder pain, therefore over 50% of respondents had muscular skeletal symptoms. In menstrual history, only 17.95% of respondents said their period was regular and painless. In respiratory history, except cold, no nasal drop & obstruction has appeared in the group of 54.02%. And 62.97% of respondents had persistent cough usually with cold and 23.41% had cough with cold breeze even if not catch cold. In the third grade of high school students, there were many complaints of pain in various parts such as headache, back pain and shoulder pain, neck pain and menstrual pain, and there was a high rate of complaints of digestive system symptom and defecation symptom. More than half of respondent had constipation discomfort, headache and musculo-skeletal symptoms, menstrual problems and cough. In the third grade of high school students, the rate of complaints of pain complaints, digestive system symptoms, and bowel symptoms was high. Therefore, there is a need for measures and management for continuous health care and health promotion in accordance with students' symptoms and age at each grade level.

SNe light curves have been used to understand the expansion history of the universe, and a lot of efforts have gone into understanding the overall shape of the radioactively powered light curve. However, we still have little direct observational evidence for the theorized SN progenitor systems. Recent studies suggest that the light curve of a supernova shortly after its explosion (< 1 day) contains valuable information about its progenitor system and can be used to set a limit on the progenitor size, R*. In order to catch the early light curve of SNe explosion and understand SNe progenitors, we are performing a ~8hr interval monitoring survey of nearby galaxies (d < 50 Mpc) with 1-m class telescopes around the world. Through this survey, we expect to catch the very early precursor emission as faint as R=21 mag (~0.1 Rsun for the progenitor). In this poster, we outline this project, and present a few scientific highlights, such as the early light curve of SN 2015F in NGC 2442.

This Study was conducted at Intensive Care Unit of H & S Hospitals from Jan 4 to April 7, 1981 on 14mail & 26female adult patients. Each patient was screened and found to have nonbacteriuria in clean catch specimen before catheterization. Clean catch apecimen through Foley catheter were obtained after 24hours, 48hours and 72hours from catheterization. The result of this study is reviewed in a statistical analysis of percentage ＆ Chi Square test to obtain the following findings. 1) The occurenc of bacteriuria in patients according to duration of indwelling catheter. a. 9.1％ of the patient showed evidence of bacteriuria 24hours post catheterization specimen and 60％ showed 48hours post cathetreization, while 68.4％ of the patient showed evidence of bacteriuria 72hours post catheterization specimen. The occurence of bacteriuria in patients were significant differences at 1％ level between duration of indwelling catheter. b. Mail patients had no infection 24hours post catheterization, 50％ displayed bacteriuria 48hours post catheterization ＆ 62.5％ displayed bacteriuria 71hours post catheterization. 11.1％ of femail patients displayed infection 24hours post catheterization 66.7％ displayed infection 48hours post catheterization and 72.7％ displayed infection 72hours post catheterization. There were significant differences at 1％ level between bacteriuria occurence of mail ＆ femail patients and the duration of insertion. 2) 56％ of those patient who have altered mental state developed bacteriuria, while 40％ of those patient who have alear mental state developed bacteriuria. But there was without statistically any significant difference between patient's mental status. 3) The occurence of bacteriuria with the administration of antibiotics in 36 patient was in 50％. The occurence of bacteriuria without the administration of antibiotics in 4 patients was in 50％. But there was without statistically any significant difference between the administration of antibiotics. 4) The occurence of bacteriuria in patients according to frequency of bladder irrigation. 50％ of those patient who irrigated twice a day developed bacteriuria, 63.6％ of those patient who irrigated once a day developed bacteriuria. The occurence of bacteriuria in patients were significant differences at 1％ level between frequency of bladder irrigation. 5) The occurence of bacteriuria in patients who did perineal care once a day was 58.1％, 22.6％ of those patient who did perineal care twice a day developed bacteriuria. But there was without statistically any signiticant differences between frequency of perineal care. 6) Most frequent bacteria of all bacterial strains isolated by culture of the urine was E. coli(45％). Enterococci & Staphylococcus were 15％ respectively.

The Japanese Flying Squid (Todarodes pacificus) is a commercially important species in South Korea and the most popular species among consumers. However commercial catches of Japanese Flying Squid have been declining since 2000. In this study, we conducted a stock assessment to identify stock status. This study differed from previous studies in two aspects: a greater amount of available fishing effort data was used, and data from China, Japan, and Korea were included. A CMSY (catch-maximum sustainable yield) model was used to estimate MSY, biomass and exploitation with Bayesian state-space implementation of the Schaefer (BSS) model for the method of stock assessment, and evaluated the species by dividing into two groups, 'Korea' and ' Korea·China·Japan'. In all cases, Japanese flying squid biomass showed a general decreasing trend. Additionally, the biomass estimated for 2020 was lower than the biomass necessary to achieve the maximum sustainable yield. To manage Japanese Flying Squid effectively, it is necessary to strengthen the resource management strategies of individual countries and prepare a cooperative plan among countries.

This paper reviews comparison analysis of current and latest application for stock identification methods of Todarodes pacificus, and the pros and cons of each method and consideration of how to compensate for each other. Todarodes pacificus which migrates wide areas in western North Pacific is important fishery resource ecologically and commercially. Todarodes pacificus is also considered as 'biological indicator' of ocean environmental changes. And changes in its short and long term catch and distribution area occur along with environmental changes. For example, while the catch of pollack, a cold water fish, has dramatically decreased until today after the climate regime shift in 1987/1988, the catch of Todarodes pacificus has been dramatically increased. Regarding the decrease in pollack catch, overfishing and climate changes were considered as the main causes, but there has been no definite reason until today. One of the reasons why there is no definite answer is related with no proper analysis about ecological and environmental aspects based on stock identification. Subpopulation is a group sharing the same gene pool through sexual reproduction process within limited boundaries having similar ecological characteristics. Each individual with same stock might be affected by different environment in temporal and spatial during the process of spawning, recruitment and then reproduction. Thereby, accurate stock analysis about the species can play an efficient alternative to comply with effective resource management and rapid changes. Four main stock analysis were applied to Todarodes pacificus: Morphologic Method, Ecological Method, Tagging Method, Genetic Method. Ecological method is studies for analysis of differences in spawning grounds by analysing the individual ecological change, distribution, migration status, parasitic state of parasite, kinds of parasite and parasite infection rate etc. Currently the method has been studying lively can identify the group in the similar environment. However It is difficult to know to identify the same genetic group in each other. Tagging Method is direct method. It can analyse cohort's migration, distribution and location of spawning, but it is very difficult to recapture tagged squids and hard to tag juveniles. Genetic method, which is for useful fishery resource stock analysis has provided the basic information regarding resource management study. Genetic method for stock analysis is determined according to markers' sensitivity and need to select high multiform of genetic markers. For stock identification, isozyme multiform has been used for genetic markers. Recently there is increase in use of makers with high range variability among DNA sequencing like mitochondria, microsatellite. Even the current morphologic method, tagging method and ecological method played important rolls through finding Todarodes pacificus' life cycle, migration route and changes in spawning grounds, it is still difficult to analyze the stock of Todarodes pacificus as those are distributed in difference seas. Lately, by taking advantages of each stock analysis method, more complicated method is being applied. If based on such analysis and genetic method for improvement are played, there will be much advance in management system for the resource fluctuation of Todarodes pacificus.

In this paper, we designed and implemented a system to easily check and manage book inventory using web and Android mobile device. In the previous conventional method, the user visits the bookstore directly and then checks the inventory. However, in this case, the user accessibility is inconvenient, and it is troublesome to check or reconfirm the inventory. In order to solve these inconveniences, we provide book inventory management system for requesting book purchase and inquiring bulletin board by book field, and then providing real time inventory check with book application and purchase functions. In addition, through the push notification function, we can catch up with the purchase status of the ordered books on the web and Android mobile device in real time. Therefore, we designed and implemented a function that enables bookstore operators and users to easily and conveniently manage by providing statistical information on inventory data.
