The fisheries resource in waters under the jurisdiction of Korea is being endangered by unlawful fishery. The Korean government exerted great efforts to establish the public order of water, but the number of the exposed unlawful fishing violations has increased for last 10 years. The system to guide fisheries regulatory noncompliance of Korea is limited to the use of fishing guidance patrol boats. For strength of monitoring and surveillance systems, the government needs to phase in Vessel Monitoring System. But there are some studies for that. The defects of present monitoring practice can be drawn from the facts described above. The qualification of the fishery control official one of most important element of fishing control system, is defined as any officer who is charging on fishing. For clear law enforcement the qualification should require considerable experience and knowledge. Korean coast guards have problems on guiding unlawful fishing violations because of the absence of administrative authority by comparison with the fisheries guiding officer, who has both authorities on administration and jurisdiction. To draw some judicial problems this research presents a analysis on the fishing control system. The research suggests the improvements to compensate the defects.

This paper analyzed factors for employees to violate information security policy in financial companies based on the theory of reasoned action (TRA), general deterrence theory (GDT), and information security awareness and moderating effects of perceived sensitivity of customer information. Using the 376 samples that were collected through both online and offline surveys, statistical tests were performed. We found that the perceived severity of sanction and information security policy support to information policy violation attitude and subjective norm but the perceived certainty of sanction and general information security awareness support to only subjective norm. Also, the moderating effects of perceived sensitivity of customer information against information policy violation attitude and subjective norm were supported. Academic implications of this study are expected to be the basis for future research on information security policy violations of financial companies; Employees' perceived sanctions and information security policy awareness have an impact on the subjective norm significantly. Practical implications are that it can provide a guide to establish information security management strategies for information security compliance; when implementing information security awareness training for employees to deter violations by emphasizing the sensitivity of customer information, a company should make their employees recognize that the customer information is very sensitive data.

The present study investigated the semantic and syntactic processes in Korean children's sentence comprehension by measuring event-related brain potentials(ERPs). The subjects were 18 right-handed, healthy native Korean children(1st graders), who were free from any hearing problems. While the children listened to the auditory sentence stimuli, ERPs were recorded with the electrodes mounted in a 'Quik-Cap' on the subject's head. The ERP data were recorded and analyzed using the NeuroScan 4.3 and EEGLABv6.03b programs. For statistical analyses, descriptive statistics, three-way repeated measures ANOVA, and t-tests were performed using a SPSS 15.0 PC program. The results indicated that semantic violations elicited a negativity (N400) ranging from 300 to 500 msec. For syntactic violations, children displayed a positivity (P600) ranging from 900 to 1,100 msec. The discovery of N400 and P600 in semantic and syntactic processes respectively, confirmed the suggestion that Indo-European and Korean languages share a common mechanism for sentence comprehension.

As a range of accidents happen frequently in our society due to safety insensitivity, researches on individual psychological characteristics related to safety behavior and on safety education are increasing. However, safety behavior research that targets university students as potential employees remains rare. Therefore, this research investigates individual characteristics and psychological factors that affect safety behaviors of university students. Research participants were 131 university students (80 males, 51 females) from the Gyeonggi-do and Chungnam areas. Psychological characteristics (self-regulation, cognitive failure, conscientiousness, and emotional stability) were included as variables that may predict university students' safety behaviors (habits, compliance, mistakes, and violations). The major findings of the study are as follows. Stepwise regression analysis showed conscientiousness was a major predictor explaining safety habits and safety compliance; Cognitive failure and emotional stability were main predictors explaining safety mistakes, and self-regulation was a major predictor explaining safety violations. These findings suggest that development of proper education programs focusing on individual characteristics would allow systematic improvement of safety behaviors of university students.

Background: Motorcycles are one of the important members of commercial transportation because of the convenient use during congested traffic conditions and the ease of parking in narrow streets. This study investigates the characteristics of crashes and traffic signal violations caused by motorcycle couriers. Methods: From the national compensation data, this study analyzed the traffic crashes caused by 671 motorcycle couriers. Results: Among 671 injured couriers, 50.6% were aged less than 40 years, 49.2% run in a small business of <5 employees, and 47.2% had work experience of <6 months. Motorcycle crashes occurred mainly due to "rider overturned alone" (67.5%), in the daytime (73.5%), or on cloudy or clear days (77.2%). However, the violation rate caused by motorcycle couriers was high in couriers in a small business of <5 employees (13.9%), with work experience of <6 months (13.9%), on cloudy or clear days (12.4%), on an intersection (29.8%), in the type of "crash with a vehicle" (31.2%), or in a death accident (35.7%) Conclusion: The findings of this study can be used as a baseline in devising policies for preventing crashes of motorcycle couriers.

Objective : The method of approach during transforaminal endoscopic lumbar discectomy (TELD) has been the subject of repeated study. However, the ideal entry point during TELD has not been studied in detail. Therefore, this study investigated the ideal entry point for avoiding complications using computed tomography (CT) scans obtained from patients in the prone position. Methods : Using CT scans obtained from patients in the prone position, we checked for retroperitoneal or visceral violations and measured the angles of approach with five conventional approach lines drawn on axial CT scans at each disc space level (L2-3, L3-4, and L4-5). We also determined the ideal entry point distance and approach angles for avoiding retroperitoneal or visceral violations. Correlation analysis was performed to identify the patient characteristics related to the ideal entry point properties. Results : We found that the far lateral approach at the L2-3 level resulted in high rates of visceral violation. However, rates of visceral violation at the L3-4 and L4-5 levels were remarkably low or absent. The ideal angles of approach decreased moving caudally along the spine, and the ideal entry point distances increased moving caudally along the spine. Weight, body mass index (BMI), and the depth of the posterior vertebral line from the skin were positively associated with the distance of the ideal entry point from the midline. Conclusion : We reviewed the risk of the extreme lateral approach by analyzing rates of retroperitoneal and visceral violations during well-known methods of approach. We suggested an ideal entry point at each level of the lumbar spine and found a positive correlation between the distance of the entry point to the midline and patient characteristics such as BMI, weight, and the depth of the posterior vertebral line from the skin.

Objective : Thoracic pedicles have special and specific properties. In particular, upper thoracic pedicles are positioned in craniocaudal plane. Therefore, manipulation of thoracic pedicle screws on the left side is difficult for right-handed surgeons. We recommend a new position to insert thoracic pedicle screw that will be much comfortable for spine surgeons. Methods : We retrospectively reviewed 33 patients who underwent upper thoracic pedicle screw instrumentation. In 15 patients, a total of 110 thoracic pedicle screws were inserted to the upper thoracic spine (T1-6) with classical position (anesthesiologist and monitor were placed near to patient's head. Surgeons were standing classically near to patient's body while patients were lying in prone position). In 18 patients, a total of 88 thoracic pedicle screws were inserted to the upper thoracic spine with the new standing position-surgeons stand by the head of the patient and the anesthesia monitor laterally and under patient's belt level. All the operations performed by the same senior spine surgeons with the help of C-arm. Postoperative computed tomography scans were obtained to assess the screw placement. The screw malposition and pedicle wall violations were divided and evaluated separately. Cortical penetration were measured and graded at either : 1-2 mm penetration, 2-4 mm penetration and >4 mm penetration. Results : Total 198 screws were inserted with two different standing positions. Of 198 screws 110 were in the classical positioning group and 88 were in the new positioning group. Incorrect screw placement was found in 33 screws (16.6%). The difference between total screw malposition by both standing positions were found to be statistically significant (p=0.011). The difference between total pedicle wall violations by both standing positions were found to be statistically significant (p=0.003). Conclusion : Right-handedness is a problem during the upper thoracic pedicle screw placement on the left side. Changing the surgeon's position standing near to patient's head could provide a much comfortable position to orient the craniocaudal plane of the thoracic pedicles.

차량전장용 제어 소프트웨어는 표준에 명시된 시스템 호출 제약사항을 위배할 경우 심각한 안전성 위협을 초래할 수 있다. 그러나 제약사항 위배는 실행경로가 복잡해질 경우 수동분석으로 색출하기 어렵고 테스팅을 통해 찾아내기도 어려워 이에 특화된 검증 방법이 필요하다. 본 연구에서는 차량전장용 제어 소프트웨어의 시스템 호출 제약사항 위배 여부를 효과적으로 검증하기 위한 두 가지 방법을 소개하고 그 효과를 실험적으로 비교하였다. 첫 번째 방법은 애플리케이션의 모든 가능한 실행경로를 탐색하고 각 경로의 제약사항 준수여부를 확인하는 방법이며, 두 번째 방법은 모델 검증 도구를 이용하여 애플리케이션이 오토마타로 표현된 제약사항을 위배하는 경우가 발생가능한지 확인하는 방법이다. 각 방법을 구현하고 실험한 결과 실행경로를 이용한 방법은 오탐을 유발하고 몇 가지 제약사항 위반을 놓치는 경우가 있는데 반해서 모델 검증을 이용한 방법은 오탐이 없었으며 비교적 큰 애플리케이션을 대상으로 보다 빠른 시간 내에 검증을 수행할 수 있음을 보였다.
