상시 비전캠프 제도가 복무 부적응 병사의 군 생활 적응 및 자아존중감에 미치는 효과

유종훈,김완일 대한군상담학회 2015 대한군상담학회지 Vol.4 No.1

상시 비전캠프는 최초 2008년 12월 1일부로 복무 부적응 병사 및 자살 우려자를 관리하기 위해 1군 예하 사?여단 에서 운영된 이후 인사 사고의 감소 효과를 나타냄으로써 2009년 6월 1일 부로 육군 사?여단급 부대로 확대 운영 되었다. 하지만 상시 비전캠프 제도의 세부 시행 지침이 사?여단장에게 위임되어 부대별 여건과 지휘관심에 따라 그 효과는 차이를 보이고 있다. 이에 본 연구는 이러한 한계를 해결하기 위해 다음과 같이 전개하였다. 연구 대상 부대를 2008년 12월 1일부, 상시 비전캠프를 시행한 이후 단 한건의 인사사고도 발생하지 않은 A여단으로 선정하 였다. 또한, A 여단의 상시 비전캠프 제도의 인사 사고예방의 효과를 검증을 하기 위해 기존 선행연구를 통해 신뢰 도와 타당도가 확인된 측정도구를 이용, 실험을 실시하였으며, 그 결과를 통계 처리와 공변량 분석을 통해 제시하 였다. 본 연구문제는 첫째, 상시 비전캠프 제도가 복무 부적응 병사의 군생활 적응에 미치는 효과는 어떠한가? 둘 째, 상시 비전캠프 제도가 복무 부적응 병사의 자아존중감에 미치는 효과는 어떠한가? 이었다. 연구문제를 규명하 기 위하여 A여단 상시 비전캠프에 입소대기중인 복무 부적응 병사 15명을 실험집단으로 구성 하였으며, 해당 부대 에서 관리중인 15명을 통제집단으로 구성하였다. 본 연구의 검사 도구는 군 생활 척도와 자아존중감 척도를 사용 하여 실험집단과 통제집단에 사전검사를 실시하였다. 그리고 상시 비전캠프가 종료되는 직후 사전검사와 동일한 방법으로 사후검사를 실시하였으며 두 집단간의 차이 검증을 실시하여 그 효과를 분석하였다. 본 연구의 결과를 요약하면 첫째, 복무 부적응 병사의 군생활 적응에 대한 실험집단과 통제집단의 차이를 보면 사전검사에서는 두 집단 간에 유의한 차이가 없었으나 사후 검사에서는 유의한 차이가 있는 것으로 나타났다. 이는 상시 비전캠프 프 로그램이 복무 부적응 병사의 군생활 적응에 유의한 효과가 있음을 나타내는 것이다. 둘째, 복무 부적응 병사의 자 아존중감에 대한 실험집단과 통제집단의 차이를 보면 사전검사에서는 두 집단간에 유의한 차이가 없었으나 사후검 사에서는 유의한 차이가 있는 것으로 나타났다. 즉 실험집단이 통제집단에 비해 자아존중감이 유의하게 상승한 것 으로 나타났다.

With considering center-biased characteristic, NTSS(New Three-Step Search Algorithm) can improve the performance of TSS(Three-Step Search Algorithm) which is one of the most popular fast block matching algorithms(BMA) to search a motion vector in a video sequence. Although NTSS has generally better quality than TSS for a small motion sequence, it is hard to say that NTSS can provide better quality than TSS for a large motion sequence. It even deteriorates the quality to increase a search window size using NTSS. In order to address this drawback, this paper aims to develop a new adaptive window size-based three step search scheme, called AWTSS, which can improve quality at various window sizes in both the small and the large motion video sequences. In this scheme, the search window size is dynamically changed to improve coding efficiency according to the characteristic of motion vectors. AWTSS can improve the video quality more than 0.5dB in case of large motion with keeping the same quality in case of small motion. NTSS 알고리즘 (New Three-Step Search Algorithm)은 대표적인 고속 블록 정합 알고리즘(Block Matching Algorithm: BMA)의 하나인 TSS 알고리즘 (Three-Step Search Algorithm)에 동영상이 갖는 중앙 편향적(Center-Biased) 특성을 반영한 방법이다. 그러나 NTSS는 움직임이 작은 동영상인 경우에는 TSS보다 개선된 성능을 보여주지만, 움직임이 큰 동영상에 대해서는 TSS와 큰 차이가 없으며, 탐색범위가 커질수록 오히려 성능이 떨어지는 단점이 있다. 본 논문에서는 움직임 벡터의 특성에 따라 적응적으로 탐색범위를 결정하여 탐색범위의 증가로 발생되는 NTSS의 단점을 보완함으로써 움직임이 큰 동영상에 대해서도 향상된 성능을 갖는 방법을 제안한다. 제안한 방법을 적용하였을 때 움직임이 작은 동영상에서는 기존 NTSS 방법과 동일한 화질을 유지하면서 움직임이 큰 동영상에서는 최대 0.5dB 이상 성능이 개선되었다.

Doxorubicin (DOX) is an anthracycline drug commonly used in the treatment of a large spectrum of tumors. It works by interfering with the growth of cancer cells. It binds and intercalates into the DNA strand, thus inhibiting further DNA and RNA biosynthesis, eventually causing cell death. Gemcitabine (GEM) is a synthetic pyrimidine nucleoside analogue with a high antitumor efficacy for ovarian, breast, bladder, and pancreatic cancer. It replaces one of the building blocks of nucleic acids, in this case cytidine, during DNA replication. The process arrests tumor growth, as new nucleosides cannot be attached to the faulty nucleoside, resulting in apoptosis. The purpose of this study is to prepare biodegradable poly(L-lactic acid) microparticles containing two different drugs by a supercritical aerosol solvent extraction system (ASES) process. The effects of operating parameters such as temperature, pressure, and drug composition on the morphology and characteristics of microparticles were studied in detail. The entrapment efficiency and in vitro release profiles of two anticancer drugs from the microparticles were also determined using HPLC. The entrapment efficiency increased with decreasing temperature. The entrapment efficiency of DOX was found to be higher than that of GEM, mainly due to larger molecular weight of DOX. On the other hand, GEM showed higher solubility in aqueous solution, thereby resulting in a faster release compared with DOX.

Cases with extranodal Hodgkin's disease located in sites outside those defined as lymphatic structure are quite rare. The exact incidence of this localized form of Hodgkin's disease is unknown, but it is estimated to be only 0.25% for overall incidence of Hodgkin's disease. Localized primary extranodal Hodgkin's disease seems to have an excellent prognosis in some cases including skin, tongue, lung, stomach, small bowel, and thyroid. We report a case of primary gastrointestinal Hodgkin's disease involved in the stomach and terminal ileum in 48-year-old man with 7 kg of weight loss for 3 months, fever with chills for 1 week, and intermittent epigastric pain for 1 year. The histologic type of this case was lymphocyte predominance, which was diagnosed by biopsy of the stomach and terminal ileum with immnophenotyping study. And the stage of this case was IIE. We tried combination chemotherapy with adriamycin, bleomycin, vinblastin, and dacabazine with excellent response. For its rarity, we report this case with review of literatures.

In this study, we attempted to evaluate the feasibility of a supercritical methanol process for direct production of biodiesel from microalgae. The effects of various factors such as temperature, reaction time, water content and pretreatment on the efficiency of biodiesel conversion were investigated. The conversion efficiency increased with both temperature and extraction/conversion time. The supercritical methanol process produced a fatty acid methyl ester (FAME) yield of around 88% within 20 minutes. The optimal conditions for this process were found to be a microalgae/methanol ratio of around 1:9, a reaction temperature of about 270℃, and a reaction time of approximately 20 minutes. The effect of water content in microalgae samples on the FAME conversion was also evaluated. The supercritical methanol process was not affected by the water content up to 250 wt%. Our experiments demonstrated that the supercritical methanol process is more effective compared with conventional in situ transesterification processes.

Purpose: This study aimed to determine whether the abdominal muscles, which are the major lumbar stabilizers along with the respiratory muscles, are affected by smoking. We compared abdominal muscle activity between smokers and non-smokers during the sit-to-stand movement. Methods: A total of 28 healthy adult males (14 smokers and 14 non-smokers) in their 20s-30s voluntarily participated in the study. The subjects performed the sit-to-stand movement, and then their abdominal muscle activity was measured. The surface electromyography system was employed to measure the maximal voluntary isometric contraction (MVIC) values of the subjects' rectus abdominis, external oblique abdominal, internal oblique abdominal, and transversus abdominis muscles. Then, the values were quantified into %MVIC. Results: The activity of the rectus abdominis muscle was higher in the smokers than in the non-smokers. Conversely, the activity of the internal oblique abdominal and transversus abdominis muscles, which are deep abdominal muscles, was higher in non-smokers than in smokers, but the difference was not statistically significant. Conclusion: Smoking can inhibit the activity of smokers' deep abdominal muscles and increase the activity of their superficial muscles, thus making it detrimental to their musculoskeletal system.

Objective: The ipsilateral nipple has been used as a directional guide for the insertion of a conventional central venous catheter via the internal jugular vein (IJV). However, the nipple is not an ideal marker since the position of the nipple varies among the characteristics of patients. The utility of the clavicle was investigated for IJV catheterization instead of the ipsilateral nipple through cadaver dissection. Methods: A total of 14 cadavers were dissected (six fresh cadavers, eight fixed cadavers). Each cadaver was kept in its supine position, and its head was rotated 30。to the left. Length A was the distance between the jugular notch and the point that the line from the nipple to sternocleidomastoid muscle apex meets the clavicle. Length B was the distance between the jugular notch and the clavicle point that passed the IJV. IJV was cut and its circumference measured at regular intervals. Results: Lengths A and B were 3.79±0.35 cm (mean±standard deviation) and 3.71±0.32 cm, respectively, and were significantly correlated (r=0.865, P<0.001). The mean circumference of the vessels were measured to be 3.56±1.29 cm in the right IJV and 3.00±1.32 cm in the left IJV with a significant difference (P=0.013). Conclusion: IJV catheterization via the right one, larger than the left one, is appropriate for the first attempt, and we recommend that the needle should be pointed at the clavicle located at a width of two fingers (2nd, 3rd finger average width 1.9 cm) away from the jugular notch.
