In order to analyze cell images, accurate segmentation of each cell is indispensable. However, the reality is that accurate cell image segmentation is not easy due to various noises, dense cells, and inconsistent shape of cells. Therefore, in this paper, we propose an algorithm that combines marker-based watershed segmentation and ellipse fitting method for glioblastoma cell segmentation. In the proposed algorithm, in order to solve the over-segmentation problem of the existing watershed method, the marker-based watershed technique is primarily performed through "seeding using local minima". In addition, as a second process, the concave point search using ellipse fitting for final segmentation based on the connection line between the concave points has been performed. To evaluate the performance of the proposed algorithm, we compared three algorithms with other algorithms along with the calculation of segmentation accuracy, and we applied the algorithm to other cell image data to check the generalization and propose a solution.

The construction of smart factories for government SMEs is not easy due to the lack of professional manpower. The use of retired professionals is a way to solve the problem to some extent and to solve the job problem of seniors by effectively utilizing social assets. This study examines the effectiveness of using Meister based on a survey of 195 companies participating in the Smart Meister Support Program. As a result, the better pre-participation readiness and the better management and coordination of change during the participation, the more significant influence was on Meister's ability development and corporate performance. In particular, it was confirmed that Meister's competence plays a role in both 'pre-participation readiness and business performance' and 'between change management during participation and business performance'. In order to improve the performance of the smart meister business in the future, it is necessary to proactively promote the purpose and purpose of the business targeting companies that wish to participate in the business. In addition, it was found that it is necessary to support the development of change management in order to minimize the resistance to innovation during the project. It will be possible to enhance social competitiveness by resolving senior jobs and strengthening the competitiveness of SMEs by discovering and utilizing Meister, who is an expert among retirees.

Recently, the number of unmanned stores is increasing due to COVID-19. In unmanned stores, payments are mainly made using kiosks, but some people with physical disabilities or people with disabilities who use wheelchairs are not easy to use it. Also, young children and the elderly are also having difficulty using new technologies such as kiosks as they get older. In this study, in order to compensate for these problems, we intend to design and implement a system capable of performing order by a speech recognition function as well as a visual system when a user interacts with a kiosk.

Recently, the explosive increase of carbapenemase-producing Enterobacterales (CPE) in the worldwide poses a serious threat. The purpose of this study is to investigate epidemiology, detection, and treatment of CPE. Three main carbapenemase are reported worldwide, which were KPC, NDM, and OXA-48-like. KPC type are mostly found in USA, China, Europe, and Latin America. NDM type are mostly found in South Asia. OXA-48-like are often seen in the Mediterranean and Northern Africa. In Korea, CPE have increased explosively since 2015. In 2021, 18,099 CPE were isolated, which were Klebsiella pneumoniae, Escherichia coli, and Enterobacter cloacae in order. The CPE genotype was distributed with KPC, NDM, OXA type in order. Phenotypic detection methods include carbapenemase production tests (CPT) and differential tests of CPE. CPTs include modified Hodge test, modified carbapenem inactivation method (mCIM), Carba NP test, among which mCIM is the most widely used due to easy accessibility and accuracy. A lot of genotypic methods are being done for quick results, and commercialized kits using multiplex real-time PCR and microarray are widely used. Colistin and tigecycline are used as the first line of CPE treatment and are used in combination with second line drugs such as meropenem and fosfomycin.

Flatfish are one of the largest families in the order Pleuronectiformes and are economically important edible marine fish species. However, they have similar morphological characteristics leading to challenges in classifying correctly, which may result in mislabeling and illegal sales, such as fraudulent labeling of processed food. Therefore, accurate identification is important to ensure the quality and safety of domestic markets in Korea. Species-specific primers were prepared from the mainly consumed eleven species of the order Pleuronectiformes. To rapidly identify the 11 flatfish species, a highly efficient, rapid, multiplex polymerase chain reaction (PCR) with species-specific primers was developed. Species-specific primer sets were designed for the mitochondrial DNA cytochrome c oxidase subunit I gene. Species-specific multiplex PCR (MSS-PCR) either specifically amplified a PCR product of a unique size or failed. This MSS-PCR analysis is easy to perform and yields reliable results in less time than the previous Sanger sequencing methods. This technique could be a powerful tool for the identification of the 11 species b the family Pleuronectidae and can contribute to the prevention of falsified labeling and protection of consumer rights.

Traditionally, finality has been regarded as one of virtues of arbitration. However in many cases absence of appeal process in arbitration is also a factor deterring people from choosing arbitration. Even though unsatisfied party may resort to a court for annulment of an award, it is allowed only when there are procedural defects. When there are substantive defects in matters of fact or matters of law, it is not easy or almost impossible to bring the case on the table again. The introduction of arbitration appeal process has been discussed in international arbitration fora, and some countries have already been adopting appeal process. Realizing this trend, it is time for us to consider adopting similar appeal process. Arbitration being based on the party autonomy, there's no good reason to prohibit appeal when the parties agree to do so. Arbitration appeal should be allowed within arbitration system itself, rather than resorting to a court, so that many virtues of arbitration can be maintained in the appeal. In designing an arbitration appeal system, following measures should be considered: minimum amount in dispute to trigger the right of appeal should be set in order to reduce the volume of appeal; losing appellant should be responsible for the legal cost of his opponent in order to deter non-meritorious appeals; time limits on initial appeal application and subsequent briefs should be set in order to accelerate appeal process; and, appeal tribunals should be composed of more experienced arbitrators in order to provide more accurate award. If we are equipped with a well designed appeal process within arbitration system, Korea will be able to emerge as an attractive international arbitration forum.

The purpose of this study is to analyze the style of the windsurfing suits and to extract main expressional words for the development of semantic differential scales of visual images according to the change in the style of windsurfing suits. The results of this study are as follows: 1) By a period of activity and its functions of windsurfing suits, they were classified into dry suit, wet suit, semi-dry suit and warm water. 2) Windsurfing suits were assorted into 4 kinds of designs: the design #1 on a suit with long sleeves and long pants, the design #2 on a suit with half sleeves and long pants, the design #3 on a suit with half sleeves and half pants, and the design #4 on sleeveless and half pants. 3) Main expressional words of visual images for windsurfing suits differ greatly depending on the design of windsurfing suits. The visual images for the design #1 are ranked in the order of 'sporty', 'looking like arms that are slim', 'looking like thighs that are slim', 'looking slim', 'neatbbb, 'practical', 'difficult to wear'. The visual images for the design #2 are placed in the order of 'sporty', 'dynamic', 'practical', 'cheerful', 'light'. The visual images for the design #3 are ranked in the order of 'sporty', 'dynamic', 'light', 'cheerful', 'masculine', 'practical'. The visual images for the design #4 are placed in the order of 'sporty', 'dynamic', 'simple', 'light', 'uncomfortable', 'easy to wear', 'looking like arms that are fat'.

A construction project consists of a variety of contracts for the completion of work. The large number of contracts involved in a single project increases the likelihood that disputes will arise between the parties involved regarding the terms of service. Actually, there are many disputes that are caused by a change 0 order. While such disputes should be settled by interpreting the terms stipulated in the agreement entered between the two parties, the process of dispute settlement is often restricted to arbitration and lawsuit, and as a result the parties tend to avoid it due to its inefficiency. For this reason, in Korea it is hard to find cases of interpreting terms of service, while in the U.S. it is easy to find diverse cases of interpreting terms of service, since there is a process of dispute settlement by each stage by the party who has placed an order. Therefore, this study presents analysis of case studies of contract changes, looking specifically at changes in the scope of the work, changes in quantity, changes in the period of implementation, changes in the method of implementation or attitude, changes in items provided by the government or the delivery place, and the acceptance of such change procedure by a contractor, and the adjustment of a reduction.

Recently, microcomputer technology has been developed rapidly and it provides not only graphic user interface that can be fraendly accessable but also large storage capacity to han- dle much hospital information. Almost all the order communication system for hospital has been developed under the concept of host and terminal environment since last 20 years. However, host-terminal system has not been successful in korea simply because most of physicians prescibe for rrlany patients a day(sometimes more than 150 patients a day). Also, under the host-terminal environment, programs are not friendly implemented for users. Since March 1991, we had developed order communication system for out-patients(named YONSEI-PC) using personal computer(PC) and local area network(LAN) . Since September 1992, we has applied succesfully in the Yonsei Cardiovascular Center, Sevrance Hospital, Yonsei University College of Medicine. This system consisted with Server and Clients which is communicated through LAN(Ethernet). The system also use the Host computer(IBM 9221 170) as a data bank and communicates to the Server with emulation card(3270 emulator, Interlink Inc., Korea) . After introducing this system, it enables patients to receive drugs witllin 20 minutes after prescription of 300-400 patients per day and it seemed to be effective system not to reduce waiting time for the patients but also to remove charge-troubling(due to His-entry of prescription) . This system also seems to be effective in terms of office automatism for hospital management. However users, usually physitions, required more friendly and easy system to operate and we thought that the most important one to successfully introduce order communication computer system in the hospital is user interface.

Objectives: In this paper, the survey on internet usage patterns of health consumers was conducted and analyzed in order to determine internet health information assessment criteria for providing correct consumer health information on web-sites. Methods: By using a survey questionnaire with 16 questions on general information and 20 questions on internet health information, data were collected from September 16 to 25, 2005 from 476 participants through an internet web site, http://www.hp.go.kr. Frequency analysis, t-test, and multiple regression were used in order to analyze the difference in assessment criteria, factors influencing assessment criteria, factors influencing user satisfaction, etc. Results: General characteristics of the study population were: the persons over age 40 were the smallest age group; women were accounted for 74.2%; and the persons with average income were the largest income group; and the persons with average health status were the largest health group. Most widely used health information were: exercise, disease, and diet, in order. There was significant difference(p=.001) in importance of assessment criteria between the persons in medical institutions and the persons not in medical institutions. There was no significant difference in other assessment criteria. We also found that contents of websites and easy to use were more important factors than elucidation of information providers and information sources including speciality of information in quality assessment criteria of internet health information. Discussion and Conclusion: Results of this paper were compared with the previous studies from the literatures. Contrary to the previous studies in the literature, there was significant difference in importance of assessment criteria between the persons in medical institutions and the persons not in medical institutions. In order to apply the study results to develop health contents for consumer, there is a need for further upgrade the proposed assessment criteria based on expert opinion.
