This study consisted of methodological research verifying the validity and reliability of the Korean version of the interpersonal emotion management (IEM) strategies scale after translating and modifying the scale developed by Little et al. The study verified the content validity, construct validity, concurrent validity and reliability based on 189 nurses working at four hospitals in the Seoul and Gyeonggi region. In this study, the Korean version of the IEM strategies scale was comprised of four factors, with a total of 15 questions that included three regarding situation modification, three regarding attention deployment, four regarding cognitive change, and five on modifying emotional response. Furthermore, verification of concurrent validity revealed that the Korean version of the IEM strategies scale was a valid tool as the correlation of the emotional intelligence scale appeared as r=0.60 (p<0.001). The reliability verification showed four factors at Cronbach's ${\alpha}=0.84-90$, confirming that the Korean version of the tool in this study was very reliable.It is important to note that this study provided basic data for the development of educational programs that can effectively control the negative emotions of clinical nurses at the organization level.

Currently the IoT (Internet of Things) environments and related technologies are being developed rapidly through the networks for connecting many intelligent objects. The IoT is providing artificial intelligent services combined with context recognition based knowledge and communication methods between human and objects and objects to objects. With the help of IoT technology, many research works are being developed using the C-ITS (Cooperative Intelligent Transport System) which uses road infrastructure and traveling vehicles as traffic control infrastructures and resources for improving and increasing driver's convenience and safety through two way communication such as bus-only lane and license plate recognition and road accidents, works ahead reports, which are eventually for advancing traffic effectiveness. In this paper, a system for deciding whether the traveling vehicle is possible or not to drive on bus-only lane in highway is researched using the lane and number plate recognition on the road in C-ITS traffic infrastructure environments. The number plates of vehicles on the straight ahead and sides are identified after the location of bus-only lane is discovered through the lane recognition method. Research results and experimental outcomes are presented which are supposed to be used by traffic management infrastructure and controlling system in future.

Objective: The purpose of this study was to investigate the clinical utility of the Korean Wechsler Intelligence Scale for Children-Fourth Edition (K-WISC-IV) and General Ability Index (GAI) in children with attention-deficit hyperactivity disorder (ADHD). Methods: The GAI and Full Scale IQ (FSIQ) in K-WISC-IV were compared for a group of 79 children with ADHD and 234 normal children. The mean differences within each group were testified by the t-test and Cohen's d. The Wechsler's descriptive classifications for each GAI and FSIQ score were analyzed in the children with ADHD. Additionally, the critical value for the difference between the means of the FSIQ and GAI was calculated in the normal children. Results: The score on the GAI was higher than that on the FSIQ in the children with ADHD, with a mean difference of 2.19 points. The implications of these findings are discussed regarding the cognitive characteristics of the children with ADHD. According to Wechsler's descriptive classification, the application of the GAI showed a lower (7.59%), equal (61.65%) or higher (60.76%) prevalence of ADHD compared to the application of FSIQ. Conclusion: The implications of these findings are discussed regarding the cognitive characteristics of the children with ADHD. The GAI reflecting the attention and behavioral problems in children with ADHD could be utilized as an alternative global intelligence estimate that considers their potential for development.

Currently, the permanent road traffic volume surveys under Road Act are conducted using a intrusive Automatic Vehicle Classification (AVC) equipments to classify 12 categories of vehicles. However, intrusive AVC equipment inevitably have friction with vehicles, and physical damage to sensors due to cracks in roads, plastic deformation, and road construction decreases the operation rate. As a result, accuracy and reliability in actual operation are deteriorated, and maintenance costs are also increasing. With the recent development of ITS technology, research to replace the intrusive AVC equipment is being conducted. However multiple equipments or self-built DB operations were required to classify 12 categories of vehicles. Therefore, this study attempted to prepare a method for classifying 12 categories of vehicles using vehicle specification information of the Vehicle Management Information System(VMIS), which is collected and managed in accordance with Motor Vehicle Management Act. In the future, it is expected to be used to upgrade and diversify road traffic statistics using vehicle specifications such as the introduction of a road traffic survey system using Automatic Number Plate Recognition(ANPR) and classification of eco-friendly vehicles.

The importance of manuals is emphasized because chemical accidents require swift response and recovery, and often result in environmental pollution and casualties. In this regard, the OECD revised OECD Guidelines for the Prevention, Preparedness, and Response to Chemical Accidents (referred to as the OECD Guidelines), in June 2023. Moreover, while existing research primarily raises awareness about chemical accidents, highlighting the need for a system-wide response including laws, regulations, and manuals, it was difficult to find comparative research on the attributes of manuals. So, this paper aims to compare and analyze the second and third editions of the OECD Guidelines, in order to uncover the information attributes and implications of the revised version. Specifically, TF-IDF (Term Frequency-Inverse Document Frequency) was applied to understand which keywords have become more important, and Word2Vec was applied to identify keywords that were used similarly and those that were differentiated. Lastly, a 2×2 matrix was proposed, identifying the topics within each quadrant to provide a deeper comparison of the information attributes of the OECD Guidelines. This study offers a framework to help researchers understand information attributes. From a practical perspective, it appears valuable for the revision of standard manuals by domestic government agencies and corporations related to chemistry.

압전재료를 이용한 능동진동제어에 관한 연구동향과 연구결과를 살펴보았다. 능동 진동제어에 사용되고 있는 감지기/작동기들 중 압전세라믹은 몇 가지 장점을 지니고 있어 그 적용에 관한 연구가 활발하게 진행되고 있는 것이 현실이며 실제 구조 물로의 적용이 이루어지고 있다. 압전세라믹을 이용한 진동제어는 박판으로 이루어진 국부구조물의 진동제어에 적합하며 그래서 자동차의 진동소음제어, 위성체 태양판의 진동제어에 사용할 수 있고 또한 겹쳐놓은 형태의 압전세라믹은 트러스 구조물의 능동 멤버로 활용할 수 있다. 이렇게 겹쳐놓은 압전세라믹 구조는 진동 고립(vibration isolation)을 원하는 장비의 지지대로 사용할 수 있어 그 응용분야가 넓다. 최근까지 도 압전세라믹을 이용한 진동제어는 주로 외팔보, 또는 평판과 같은 단순한 기하학적 형상을 가진 구조물에 국한되어 연구가 진행되어 왔고 제어기법 또한 그동안 전기 제어분야에서 개발되어 온 기법들을 적용하는 현상을 보였는데 구조물의 자유도가 무한대임을 고려할때 앞으로 구조물에 합당한 제어기법의 개발이 요망된다고 하겠다. 이 논문에서 선보인 PPF와 SRF 제어 기법은 필자가 간단히 회로를 구성하여 실험을 수행하였는데 압전재료의 진동제어 기법으로 단순하면서도 효율적인 제어기법이라고 말할 수 있다. 압전재료를 이용한 진동제어에 관한 국내의 연구활동이 미미한 상태 이으로 이분야에 대한 연구자들의 관심을 모을 필요가 있다. 압전세라믹 감지기와 작동기의 설치는 그동안 압전세라믹 판을 직접 구조물에 접착시킨 형태로 진행되었 는데 새로운 형태의 압전세라믹 작동기의 개발이 시급하다. 이는 높은 전압을 필요로 하는 진동제어는 필수적으로 커다란 부대시설을 요구하게 됨으로 전압을 높이지 않고 도 진동제어를 효율적으로 할 수 있는 압전세라믹의 제조가 필요하다고 하겠다. 필자 는 이런 목적으로 다층 압전세라믹(multilayer piezoceramic plate)을 제작한 적이 있었는데 실험결과는 신통치 않았다. 또한 압전세라믹을 길고 얇은 조각으로 잘라 사용하는 방법로 있었으나 세라믹의 절단시 다이아몬드 컷터를 사용해야 되어 제작이 곤란했다. 또한 압전세라믹이 부서지기 쉬운점을 개선한다면 진동제어에 있어 아주 효과적인 감지기/작동기가 될 수 있을 것이다.

Noonan syndrome is characterized by a Turner-like phenotype and a normal karyotype associated with congenital abnormalities, such as short stature, variable mental retardation, hypertelorism, webbed neck, low posterior hair line, skeletal malformation and congenital cardiovascular defect. Two third of Noonan syndrome have cardiac anormalies, half with pulmonary stenosis. We have experienced two cases of pulmonary stenosis associated with other cardiac anomalies in Noonan syndrome. The first 31-year-old male patient had characteristic appearance of Noonan syndrome with severe infundibular pulmonic stenosis and patent foramen ovate. The second 28-year-old male patient had valvular and subvalvular Pulmonary stenosis with typical Noonan\`s face and stature. Pulmonary valvotomy and hypertrophied muscle bundles in the right ventricular cavity were resected in both cases. Patent foramen ovate was closed directly in the first case. Postoperative follow-up examinations revealed no symptoms and successful outcome.

Objective : The purpose of this study was to investigate the cognitive performance of major depressive disorder (MDD) in military service/conscription personnel who visited the psychiatric clinic for a medical certificate to consider the situation from the perspective of Korea's unique compulsory military system. We used the Korean Wechsler Adult Intelligence Scale-IV (K-WAIS-IV) as the test for verifying the suitable level of cognitive functioning for military service and as the embedded measure with reflecting suboptimal effort. Methods : The study was conducted on 56 (28 males, age 19-34) in/out-patients admitted to the psychiatry department and diagnosed with MDD (DSM-IV). All participants completed a structured clinical interview (MINI-Plus), as well as self-report questionnaires related to demographics and severity of clinical symptoms. K-WAIS-IV was administered to each subject to assess cognitive characteristics. Results : Military group showed significantly lower processing speed index (PSI) score including subtests of symbol search (SS) and coding (CD) score, compared to the control group. There was no other significant differences in the Full Scale IQ (FSIQ), Verbal Comprehension Index (VCI), Perceptual Reasoning Index (PRI), Working Memory Index (WMI) scores including sub-tests comprised of the above indices, and Reliable Digit Span (RDS), Enhanced-RDS-Revised (E-RDS-R) between the study and control groups. Conclusion : This study was the first effort to verify the characteristics of Korea's military group with MDD and suggest the applicability of PSI and processing speed of K-WAIS-IV as an embedded performance index to test sub-optimal effort or low motivation beyond the purpose of testing cognitive deficits.
