  • 1997년 외환위기 이후 국내 부실기업의 해외매각을 빠른 속도로 진행하여 매각과정에서 협상력 부재로 인해 기업가치를 제대로 평가받지 못하였을 뿐만 아니라 계약조건 부분에 있어서도 협상성과는 매우 낮은 것으로 평가되고 있다. 또한, 부실한 계약조건으로 인해 계약이행이 종료되지 못하고 소송이나 중재와 같은 분쟁발생이 급격이 증가하고 있다. 이러한 문제인식 하에 본 논문은 부실기업 매각협상 사례중 국제중재와 관련된 한보철강 매각의 사례를 통해 매각시 국제중재를 통해 분쟁을 해결하는 과정을 상세하게 설명함으로써 향후 매각협상 과정뿐만 아니라 매각이후 분쟁이 실제로 발생한다면 이에 대한 정확한 대처와 중재 대처 전략을 수립할 수 있도록 하기 위함이다. 중재는 소송과 달리 단심제로서 중재기간이 상대적으로 짧다고 볼 수 있으나 단심제의 특성을 감안하여 최대한 유리한 증거와 증인확보 등 보다 더 적극적인 자세로 임해야 할 것이다. 본 사례연구에서 중요한 시사점은 국내 협상자들이 협상시 매각가격에만 중요성을 부여하며 기타 계약조건 특히, 준거법 및 관할권에 대해 소홀히 취급하는 경향이 있다는 점이다. 본 한보 중재에서도 승리의 결정적인 원인은 바로 계약서에 준거법을 한국법이라고 명시하였기 때문에 가능했던 것이다 이러한 점은 향후 국제협상시 중요하게 다루어져야 할 사항이라고 판단된다.

  • 담수 생물종 시식역의 보전을 위해 하천 연결성 유지와 회복이 중요하지만, 하천관리에 있어 이를 고려하기 위한 기초자료나 관련 연구가 부족한 실정이다. 특히 인공장벽(artificial barrier) 영향에 대한 대부분의 연구는 어류이동에 초점을 두고 있거나, 그 공간적 범위를 제한하는 경향이 있다. 본 연구는 강과 하천을 연속체 개념으로 접근하여 생태학적 과정을 방해할 수 있는 모든 인위적 구조물을 인공장벽으로 간주하고, 댐과 저수지, 보와 같이 하천의 종적 연결성을 저해하는 3개 유형의 인공 구조물에 대해 공간자료를 구축하였다. 수치지형도로부터 하천중심선과 수리시설물(보), 호소 및 저수지 경계를 교차(intersection) 분석하여 유형별 구조물의 위치 정보를 추출하고, 기존 자료와의 비교·검증을 통해 자료의 신뢰성을 도모하였다. 인공장벽에 대한 공간자료는 구조물의 유형에 따라 국가하천과 지방하천, 소하천으로 구분하고 낙동강 대권역 내 총 195개 표준유역에 대해 밀도(barrier density)를 계산하였는데, 여기서의 밀도는 하천 연장에 대한 총 인공장벽의 수로 정의(barriers/km)된다. 본 연구의 주요 결과는 낙동강 유역 내 인공 장벽의 밀도와 유형, 하천별 공간분포에 대한 정량적 평가를 포함하고 있으며, 이를 기반으로 수생태계 연결성 회복을 위한 하천관리방안을 모색하고자 하였다. 분석 방법과 결과 등 자세한 내용은 발표를 통해 제시될 예정이다.

  • Purpose: To evaluate the usefulness of the $HexaPOD^{TM}$ evo RT system(6DoF couch) and the tendency of dose difference according to size of rotational direction error for volumetric rotational modulated radiotherapy(V-MAT) in patients with long target lengths. Therefore, it is suggested to recommend the need for rotational error correction. Materials and Methods: Ten patients with Esophagus cancer or Breast cancer including SCL treated with HexaPOD 6DoF(Six-Degree of Freedom) couch were included in this study. 6DoF couch was used to measure the difference in dose according to the rotation error in the directions of Rx(pitch), Ry(roll), and Rz(yaw). Each rotation error was applied. Positioning variation on x, y and z axis was verified and random variations were made by 6DoF couch with positioning variation. Modified DQA is conducted and point dose and gamma value are analyzed and compared. In addition, after applying the rotation error every $1^{\circ}$ to treatment plans of each target with a diameter of 3 cm, 5, 10, 15, and 20 cm respectively, gamma passing rate is being monitored by its aspect of change according to types and sizes of the target length and rotation error. Results: Mean error of the point dose and Gamma passing rate when the position variation was applied were $2.50{\pm}1.11%$ and $84.1{\pm}7.39%$ in the Rx direction, $2.36{\pm}1.16%$, and $81.0{\pm}8.49%$ in the Ry, $2.35{\pm}1.10%$ and $84.4{\pm}6.99%$ in the Rz direction, respectively. As a result of analysis on gamma passing rate according to types and sizes of the target length and rotation error, the gamma passing rate tended to decrease with increasing rotation error in the Rx and Rz directions except Ry direction. In particular, the lowest gamma passing rate (74.2 %) was in the case of $2.5^{\circ}$ rotation error in Rz direction of the target of 10 cm. Conclusion: The correction of the rotational error is needed for volumetric modulated radiotherapy of the treatment area with a long target length, and the use of 6DoF couch will improve the reproducibility of the patient position and the quality of the treatment.

  • X-ray Chest P-A is very important and basic diagnosis examination for pregnant women. For a pregnancy period pregnant women should be treated very carefully not to be exposed to any radiation which might cause harmful damage to women and babies as well. Lead apron is one of the effective methods to protect pregnant women from the X-ray radiation. However, it is difficult to obtain the accurate position of pregnant women during X-ray Chest P-A since conventional lead apron method forces pregnant women to hold the apron by themselves only to make pregnant women very uncomfortable and hard to maintain accurate position during radiation. As a consequence, it is common to get low quality images of X-ray Chest P-A due to the overlap of apex of lung and scapular. In order to fix this problem, we made new design lead apron that allowed pregnant women to be more comfortable to maintain accurate position during X-ray Chest P-A position. Finally, with this new design lead apron, it was possible to get the best optimized images of X-ray Chest P-A of pregnant women by minimizing overlapping apex of lung and scapular.

  • Fold axis of fold, a representative ductile deformation structure, is important for collecting information on the 3D fold structure and the orientation of maximum horizontal principal stress at the time of deformation. For this reason, several fold axis measurement methods based on the fold-related structural elements have been suggested and used even in areas where it is impossible to measure it directly. Thus, these various measurement methods are briefly introduced here, and the measured data with different methods are compared to estimate these methods' reliability. For this purpose, we acquired fold axes at six sites across the Manhang formation of the Pyeongan supergroup and limestones of the Joseon supergroup in Danyang, Chungcheongbuk-do, where fold structures are well developed. The data from the different methods are generally consistent, indicating practical applicability. Most of the fold axes from the measured sites show NNNE or NE trends indicating WNW-ESE or NW-SE trending maximum horizontal principal stress, except for the one site with a WNW trend. The WNW-ESE trending fold axis might be related to a different orogeny or secondary folding. The minor difference in the trends between N-NNE and NE was interpreted as being due to different scale; however, further research is needed to confirm this.

  • Flux cored arc welding (FCAW), which is used widely in many fields, such as shipyards, bridge structures, construction machinery, and plant industry, is an alternative to shielded metal arc welding (SMAW). FCAW is used largely in the welding of carbon and alloy steel because it can be welded in all poses and obtain excellent quality in the field under a range of working conditions. In this study, the mechanical properties of welded parts were analyzed after different welding of SS400 and SM490A using FCAW. The following conclusions were drawn. The tensile test results satisfied the KS standard tensile strength in the range of 400~510 N/mm2 in all welding positions. The bending test confirmed that most of the specimens did not show surface breakage or other defects during bending and exhibited sufficient toughness, even after plastic deformation. The hardness test results were lower than the standard value of 350 Hv of KS B 0893. Similar to the hardness test, were greater than the KS reference value. The macro test revealed no internal flaws, non-metallic inclusions, bubbles or impurities on the entire cross section of the weld, and there were no concerns regarding lamination.

  • High-Resolution thoracic CT (HRCT) is a scanning protocol in which thin slice thickness and sharpness algorithm are utilized to enhance image resolution for diagnosis and assessment of interstitial lung disease (ILD). This examination is sometimes performed in both supine and prone position to improve sensitivity to early changes of these conditions. Anatomical structures (the size of lung field and heart and descending aorta) of 150 patients who underwent HRCT were retrospectively compared. HRCT had been conducted in two positions (supine and prone). Data were divided into five groups according to patient body weights (from 40 to more than 80kg, 10kg intervals, 60 patients/each group). Quantitative analysis was utilized in Image J program. In the supine position defined as the control group, the average values of lung fields and heart size and aorta were compared with the prone position defined as the experimental group. The size of the lungs was found to be higher in the supine position, and it was confirmed that there was a statistically significant difference in patients over 70 kg (p<0.05). In addition, both sizes of the heart and descending aorta were larger in prone position, but in the case of the heart, there was no correlation with the presence or absence of ILD disease (p>0.05). Also, the area of prone in the descending aorta was higher than supine position, but there was no statistically significant difference between supine and prone position (p>0.05). In conclusion, when the severity of ILD disease was severe, there was no statistically significant difference in the area difference between supine and prone position, so it is considered that it will be helpful in diagnostic decision.

  • There are various items in the safety and health standards of the manufacturing industry, but they can be divided into work-related diseases and musculoskeletal diseases according to the standards for sickness and accident victims. Musculoskeletal diseases occur frequently in manufacturing and can lead to a decrease in labor productivity and a weakening of competitiveness in manufacturing. In this paper, to detect the musculoskeletal harmful factors of manufacturing workers, we defined the musculoskeletal load work factor analysis, harmful load working postures, and key points matching, and constructed data for Artificial Intelligence(AI) learning. To check the effectiveness of the suggested dataset, AI algorithms such as YOLO, Lite-HRNet, and EfficientNet were used to train and verify. Our experimental results the human detection accuracy is 99%, the key points matching accuracy of the detected person is @AP0.5 88%, and the accuracy of working postures evaluation by integrating the inferred matching positions is LEGS 72.2%, NECT 85.7%, TRUNK 81.9%, UPPERARM 79.8%, and LOWERARM 92.7%, and considered the necessity for research that can prevent deep learning-based musculoskeletal diseases.

  • Objective: This study examined the effectiveness of Korean medicine treatments in two patients with Parkinson's disease complaining of discomfort stemming from postural instability and gait disturbance (PIGD). Methods: Two patients were treated for 3 months. They visited the clinic once a week for the first month and thereafter once every 2 weeks. The Unified Parkinson's Disease Rating Scale (UPDRS) and a three-dimensional gait analysis were performed at the first visit and at 1, 2, and 3 months thereafter. Results: In Case 1, gait speed, stride length, and swing phase increased. Double support decreased until 2 months after treatment but increased slightly after 3 months. Among the kinematic parameters, tilt and rotation increased. The total UPDRS Part III score decreased from 51 points to 29 points after 3 months of treatment. In Case 2, gait speed, stride length, and swing phase increased, but double support decreased. Among the kinematic parameters, tilt, rotation, and obliquity decreased. The total UPDRS Part III score decreased from 11 points to 7 points after 3 months of treatment. Conclusions: This study suggests that Korean medicine can be an effective treatment for patients with Parkinson's disease who experience discomfort due to PIGD.
