  • This study aims to analyze the current status of timber production operation and the effects of the forestry mechanization projects on timber production. In order to increase the domestic timber production, it is necessary to propel forestry mechanization project, improve policy and institution, broaden forest-road network, enlarge the number of forest workers, enhance timber production and supply system, provide forestry machines, establish forest operation system, and train forest workers. In addition, the reestablishment of policy goals, the consistency of policy, and the rearrangement of laws and institution are considered more important. To improve the results and effects of forestry mechanization project, it is necessary to drive of forestry mechanization project, the spread of forestry machines, the cultivation of trainer ability, the development of training materials, and the teaching of field skill. In order to meet timber buyersí preference, timber needs to be produced through whole tree logging operation system. Expanding the proportion of domestic timber among total timber demand in Korea requires price competitiveness, and the supply ability of high quality product from the perspective of length and width.

  • Inguinal hernia is a major surgical disease in pediatric surgery, occurring in 3.5% to 5% of all mature newborns and 9% to 11% of all premature babies. The objective of this study is to analyze the predisposing factors in association with recurrences of inguinal hernias in infants and children. In the period from January 1995 to September 2001, 1,575 infants and children who had primary inguinal hernias or recurrent inguinal hernias operated on at the Department of Pediatric Surgery at Seoul National University Hospital were evaluated retrospectively. We evaluated the data by medical records and by telephone interview. The sex, age, location of hernia, comorbidity, prematurity, incarceration, interval to operation after incarceration, postoperative complications were analyzed as predisposing factors in associated with hernia recurrence. Operative findings of recurrent inguinal hernia were reviewed. The data were statistically analyzed with Pearson Chi-Square test and Fisher-exact test. A total of eighteen (1.14%) out of 1,575 patients underwent an operation due to recurrent inguinal hernia. In 5 (27.8%) out of 18 recurred patients, institution of the primary herniorrhaphy was our hospital and in the other 13 (72.2%) was outside hospital. No impact on the development of recurrences was seen for sex, age, interval to operation after incarceration, and postoperative complications. The significant predisposing factors of recurrent inguinal hernias were left inguinal hernias (p=0.002), comorbidity (p=0.002), prematurity (p=0.006), incarceration (p=0.017) and technical error of first herniorrhaphy. We expect that knowledge for predisposing factors of recurrent inguinal hernias and experienced skill of pediatric surgeons will decrease recurrence rate in primary inguinal hernia.

  • Welding work is a production work method widely used throughout the industry, and various types of welding technologies exist. In addition, many methods are being studied to automate these welding operations using robots, but in the ship manufacturing field, welding such as painting, cutting, and grinding is also the most common operation, but the manual operation ratio is higher than in other industries. Such a high manual labor ratio in the field of ship manufacturing not only causes quality problems and production delays according to the skill of workers, but also causes problems in the supply and demand of manpower. Therefore, this paper analyzed the reason why the automation rate is low in welding work at ship manufacturing sites compared to other industries, and analyzed the production process and field environment for small and medium-sized ship manufacturing companies that repeatedly manufactured with a small quantity production method. Based on the analysis results, it is intended to propose a robot system that can easily move between workplaces and secure uniform welding quality and productivity by collaborating simple welding tasks with humans. Finally, the simulation environment is constructed and analyzed to secure the suitability of robot system application to current production site environment, work process, and productivity, rather than to develop and apply the proposed robot system. Through such pre-simulation and robot system suitability analysis, it is expected to reduce trial and error that may occur in actual field installation and operation, and to improve the possibility of robot application and positive perception of robot system at ship manufacturing sites.

  • Recently, a plastic surgery hospital in Seoul, has been raided following suspicions that ghost surgery was performed by an unauthorized substitute surgeon on a chinese woman who lapsed into a death. Following the incident, an organization to eradicate ghost surgery was created in March by Consumers Korea, founded to protect consumer rights, and the Korea Alliance of Patients Organization. The organization has received reports of illegal medical practices. To substitute another physician without the patient's consent and without his knowledge of the substitution is fraud and deceit and a violation of a basic ethical concept. The patient as a human being is entitled to choose his own physician and he should be permitted to acquiesce in or refuse to accept the substitution. It should be noted that it is the operating surgeon to whom the patient grants his consent to perform the operation. The patient is entitled to the services of the particular surgeon with whom he contracts. The surgeon, in accepting the patient, obligates himself to utilize his personal talents in the performance of the operation to the extent required by the agreement creating the physician-patient relationship. He cannot properly delegate to another the duties which the patient authorizes him to perform personally. 'Ghost surgery' comes under Article 257(Inflicting Bodily Injury on Other or on Lineal Ascendant) of the Criminal Code. Substitution another physician without the patient's consent and without his knowledge of the substitution shall be performed Inflicting Bodily Injury. This is a controversial issue that'ghost surgery' comes under Article 347(Fraud) of the Criminal Code. It maybe controversial that operation substituted by another physician without the patient's consent and without his knowledge of the substitution becomes the component of Fraud. Also, Ghost surgery' comes under Article 27 (Prohibition of Unlicensed Medical Practice, etc.), Article 22 (Medical Records, etc.), Article 33 (Establishment) of the Medical Service Act. The surgeon's obligation to the patient requires him to perform the surgical operation: (1) within the scope of authority granted him by the consent to the operation; (2) in accordance with the terms of the contractual relationship; (3) with complete disclosure of all facts relevant to the need and the performance of the operation; and (4) to utilize his best skill in performing the operation.

  • Generally, small and medium scale enterprises have conventionally been performing diligence and indolence management by hand, but many of them have been recently costing a lot of money for their diligence and indolence management and security maintenance. But yet, they have annoying sides due to the initial stage cost for the introduction of the system which is consisted of a terminal for reading a card, an RFID card, an administrative sewer and an application program for the diligence and indolence management as well as the insufficiency of the fixing skill being able to cope with the problems originating from hardware and software troubles. For this reasons, we developed a new diligence and indolence management system that the initial stage cost is moderate because it is needless to purchase a new server and to issue a new card, and the operation and management of the system is convenient because an RFID card reader communicates with a central administrative server in IDC(Internet Data Center) over internet for the diligence and indolence management.

  • Objectives: This study assessed the status of domestic industrial hygiene laboratories using data from on-site investigation for revision of quality control systems in 2012-2013. Methods: The target laboratories were 60 industrial hygiene laboratories chosen by random selection and nationwide distribution which had participated in on-site investigations for revision of quality control systems from March 2012 to August 2013. The investigation was performed on-site following standard quality control procedures. The score between each group was compared using Mann-Whitney and Kruskal-Wallis tests, and the correlation between analytical career, sex, academic major of analyst and score of analytical performance was expressed as Spearman's rank correlation coefficient. Results: The assessment revealed that the items to be improved, in sequence, were effort at staff training (score 65.5), ability to calculate data (score 73.4), establishment of internal quality control guidelines (score 75.7), laboratory facilities (score 77.1), degree of understanding and skill at gas chromatography (score 77.1). Analysis performance showed a positive correlation with career of analyst (r=0.56, p<0.01). Conclusions: The practice of on-site investigation for quality control systems showed the current status of industrial hygiene laboratories in the first trial. There were many laboratories which needed improvement and development of analytical systems. This assessment can provide information for the systematic operation and improvement of facilities at each laboratory. Further practice of this investigation will lead to a proficiency testing and accreditation system for autonomous quality control as is the practice in many countries, rather than mandatory practice by legal regulation.

  • Background Carpal tunnel release is one of the most common surgical procedures performed by hand surgeons. The authors created a surgical simulation of open carpal tunnel release utilizing a mobile and rehearsal platform app. This study was performed in order to validate the simulator as an effective training platform for carpal tunnel release. Methods The simulator was evaluated using a number of metrics: construct validity (the ability to identify variability in skill levels), face validity (the perceived ability of the simulator to teach the intended material), content validity (that the simulator was an accurate representation of the intended operation), and acceptability validity (willingness of the desired user group to adopt this method of training). Novices and experts were recruited. Each group was tested, and all participants were assigned an objective score, which served as construct validation. A Likert-scale questionnaire was administered to gauge face, content, and acceptability validity. Results Twenty novices and 10 experts were recruited for this study. The objective performance scores from the expert group were significantly higher than those of the novice group, with surgeons scoring a median of 74% and medical students scoring a median of 45%. The questionnaire responses indicated face, content, and acceptability validation. Conclusions This mobile-based surgical simulation platform provides step-by-step instruction for a variety of surgical procedures. The findings of this study help to demonstrate its utility as a learning tool, as we confirmed construct, face, content, and acceptability validity for carpal tunnel release. This easy-to-use educational tool may help bring surgical education to a new- and highly mobile-level.

  • Liberal education in colleges and universities embrace the concept of general education to enhance individual's morality, intelligence and identity. In consideration of physical education aim to develop cognitive, psychomotor and affective domains as a whole person education, liberal education and general physical education share the same values and objectives. Suppose physical education and liberal education shared same initial values, general physical education should take possession of the core means to achieve liberal education goals. To this end, it is necessary to inspect the actual statement of general physical education curriculum carefully, to find potential problems and prevent them in advance, and also explore future directions. In the current investigation, researchers found potential problems through identifying operation status of general physical education in 10 national universities. In addition, researcher provided future directions of general physical education in college and university including 'take possession of core means for liberal education', 'making diverse general physical education curriculum', 'move away from physical skill-centered education', 'general physical education as a whole body education' and 'increase opportunity of general physical education'.

  • While relevant fields of construction industry have rapidly changed, the adaptation (skill) level of individuals to apply or utilize them has slowly followed. By understanding how individuals resist and conform under this change of construction industry and which factors are important for the adaptation, much time, effort, and cost can be saved for organization operation and management, and these saved resources will be able to be effectively invested to others. Accordingly, for construction industry it is necessary to understand and study how the users fit into the rapid technological change. Through this research, therefore, a systematic guideline should be created for the relevant fields of construction industry. For this research, the characteristics of individual personalities and behaviors based on the traditional model was observed and factors that contribute to the resistance and their mutual relations were theoretically identified and categorized, and then a conceptual and figurative model to show the mutual relation between the identified resistive factors was suggested.
