This study aims at clarifying that Kim, So-Wol`s poetics is based on LiKi(理氣)philosophy. And this is to show the distinction between Western ideas like Romanticism which is accepted by Kim-uk and So-Wol`s traditional poetics. The results are as follows. First, So-Wol is realized paradoxical sense which can find out positive meaning from negative thing and overcome Western dichotomy by LiKijimyo(理氣之妙) principal means that Li(理) as Hyungisanja(形而上者: metaphysical thing) and Ki(氣) as Hyungihaja (形而下者: physical thing)are neither divided nor united. Second, So-Wol emphasizes that immutable character of Sihon(詩 魂) on his poetics because he wants to show Li`s character as inevitable cause and right. As he authorizes Sihon(詩魂) ontological and axiological character of Li, Sihon(詩魂) has Good truth and thereby has good effect for society. Unlike Kim-uk`s romanticism, to display subjectivity on So-Wol`s poetics is based on LiKi philosophy has a effect for society, because the subjectivity has a moral sensibility. Last, like Li and Ki, Sihon(詩魂) is manifested on poetry by Umyoung(陰影), so poetry is valuated by not Sihon but Umyoung. But So-Wol contradicted himself by asserting that Umyoung(陰影) isn`t discussed merits and demerits. This is explained by considering LiKijimyo(理氣之妙). Ki is a manifestation of Li, therefore when we see poetry as Ki with view is based on authenticity, Ki is not a thing of judgement. But when we poetry with view is based on substantiality, Ki is a thing of judgement. In conclusion, So-Wol intended to include not only eternal nature but also substantiality on modern poetry with LiKi(理氣) philosophy.

풍력에너지는 낮에 비해 야간에 많은 잉여전력을 발생시키기 때문에 야간에 생산되는 전력은 버려지고 있는데, 이 문제를 해결하기 위해 풍력 등 재생에너지를 연계한 수전해 하이브리드 시스템 개발이 활발히 이루어지고 있다. 본 연구에서는 하이브리드 시스템 안전성 향상을 위해 국내 외 수전해 시스템 기준의 평가항목을 분석하였고, 평가 항목을 토대로 수전해 시스템의 안전성능 시험항목을 도출하였다. $5Nm^3/hr$급 수전해 시스템의 안전성능 평가를 위하여 시험항목 중 효율측정시험, 수소발생압력시험, 수소 순도시험을 평가하였다. 그 결과 수소발생량은 $5.10Nm^3/hr$, 스택효율은 $4.97kWh/Nm^3$로 산출되었고, 이때 발생한 수소의 순도는 99.993%로 국제기준 ISO 14687, SAE J2719에 명시된 순도보다 높은 순도의 수소를 생산하였음을 확인할 수 있었다. 본 연구 결과는 향후 수전해 시스템의 구축과 안전성능을 평가에 도움이 될 것이라고 기대한다. The wind energy produced at night is being discarded because of the excess power generated at night compared to daytime. To solve this problem, In this study, we analyzed the evaluation contents for evaluation of domestic and overseas water electrolysis systems and drew contents for safety performance contents test of the water electrolysis system based on the evaluation contents. The test contents produced the efficiency measurement test, the hydrogen generated pressure test, and the hydrogen purity test. And the safety performance evaluation of the alkaline water electrolysis system of $5Nm^3/hr$ was performed based on the results. As a result, the hydrogen generation was calculated as $5.10Nm^3/hr$ and the stack efficiency was $4.97kWh/Nm^3$. The purity of the hydrogen generated was 99.993% and it was confirmed that it produced high purity hydrogen. I think will help us assess and build safety performance of water electrolysis systems in the future.

김지혜,성동욱,김정욱,신진호,이순근,정경일,엄종권,이기남,성호진,김윤현,김혁주,Kim, Jee Hye,Sung, Dong-Wook,Kim, Jeong Wook,Shin, Jin Ho,Lee, Soon Keun,Jung, Kyung Il,Uhm, Jong Kwan,Lee, Ki Nam,Seong, Ho Jin,Kim, Youn Hyun,Kim, Hyeog J 한국의학물리학회 2013 의학물리 Vol.24 No.2

방사선 검사에서 CR, DR의 도입으로 인해 X-선속 조사야의 사용이 경시되고 있는 실정이다. 일반방사선 검사에서 검사 부위별 조사야를 적절히 사용하고 있는지에 대해 현장 실태 조사와 설문 조사하고, 조사야의 기준의 필요성을 강조하며 표준 조사야를 제시하고자 한다. 서울, 경기도, 전라도, 충청도, 강원도, 부산 지역 총 333개 의료기관을 대상으로 X-선속 조사야의 사용 실태를 현장 조사하여, 검사부위별, 의료기관종별, 영상종류별로 조사야 조절의 사용 여부를 분석하였다. 또한 조사야 조절이 방사선피폭에 미치는 영향과 인식을 평가하기 위해 종합병원 10곳, 병원 10곳, 의원 10곳의 일반촬영실에 근무하는 168명의 방사선사를 대상으로 X-선속 조사야 조절이 환자피폭선량 저감화에 끼치는 영향에 대한 인식, 조사야 조절 방법과 실제 사용하고 있는 검사부위별 X-선속 조사야 크기를 설문 조사하였다. 검사부위별 적합한 조사야을 사용하고 있는 의료기관은 61.3%이었으나, 주요 장기가 밀집된 요추 검사의 경우에는 적합한 사용이 49.9%에 불과하였다. 의료기관종별에서는 종합병원이 약 69%, 영상종류별로 보면 DR을 사용하는 병원의 65.0%에서 적합한 조사야을 사용하였다. 설문 조사에서는 응답자의 97.6%가 조사야 조절이 환자에게 끼치는 선량을 줄일 수 있다고 인식하고 있었으나, 실제로 부위별 X-선속 조사야의 크기를 조절하여 검사하는 경우는 83.3%이었다. 일반방사선 검사에서 적절한 조사야를 사용하는 경우가 실태조사를 통해 낮게 나타났으며 이는 환자에 대한 방사선 피폭선량을 줄이기 위한 노력이 시급히 필요하며, 조사야에 대한 통일된 표준 규격이 필요하여 철저한 교육이 동반되어야 한다. Due to the introduction of CR and DR, it has been neglected the use of the X-ray beam collimator and field size. This study examines nationwide survey of the proper use of collimator and field size by area in a specific field of plain radiography and the current status. Authors emphasized the need for the field size criteria, and propose a standard reference field size in each specific radiologic examination. Total 333 medical institutions (included in Seoul, Gyeonggi-do, Jeolla, Chungcheong, Gangwon-do, Busan area), were investigated in relation to the status of the X-ray beam collimation field size, type specific inspection areas, medical facilities, and image analyses by type to figure out whether they use the adjustment of image field to the specific examination. To assess the awareness and the impact of radiation exposure to the collimation adjustable, 168 radiographers who was working in 10 general hospitals, 10 hospitals, and 10 clinics, were surveyed how they haver adjusted the actual field size. We examine that 61.3% of medical institutions used the "Proper collimation" and only 49.9% of them employed proper one in lumbar spine densely crowded by major organs. 69% among general hospitals, and 65% among hospitals using DR system were using proper collimation. Radiographers recognized that proper adjustment of collimation could reduce the harmful radiation dose on patients. In the survey, 97.6% of respondents were aware of this fact, but only 83.3% of respondents did the adjustment of the size of the collimation field. The using of proper collimation field was low in the nationwide survey, so the effort to reduce the radiation dose on the patients is urgently needed. A unified standard for the field accompanied by thorough education should be needed.

A fundamental study was carried out to develop a process for recycling tungsten and cobalt from WC-Co hardmetal sludge generated in the manufacturing process of hardmetal tools. The complete extraction of cobalt and simultaneous formation of tungstic was achieved by treating the sludge using aqua regia. The effect of aqua regia concentration, reaction temperature and time, pulp density on cobalt leaching and tungstic acid formation was investigated. The complete leaching of cobalt was attained at the optimum conditions: 100 vol.% aqua regia concentration, $100^{\circ}C$ temperature, 60 min. reaction time and 400 g/L pulp density. A complete conversion of tungsten carbide of the sludge to tungstic acid was however, obtained at the pulp densities lower than 150 g/L under the above condition. The progress of reaction during the aqua regia treatment of the sludge was monitored through the XRD phase identification of the residue. The metallic impurities in the tungstic acid so produced could be further removed as insoluble residues by dissolving the tungsten values in ammonia solution. The ammonium paratungstate($(NH_4)_{10}{\cdot}H_2W_{12}O_{42}{\cdot}4H_2O$) of 99.85% purity was prepared from the ammonium polytungstate solution by the evaporation crystallization method. 초경공구의 제조공정에서 발생하는 WC-Co 초경합금 슬러지로부터 텅스텐의 순환활용을 위한 기초연구가 수행되었다. 왕수를 사용하여 슬러지로부터 코발트를 침출함과 동시에 탄화텅스텐을 텅스텐산으로 변환시켜 회수하였다. 왕수농도, 반응온도와 시간, 광액농도 등이 코발트의 침출과 텅스텐산의 생성에 미치는 영향을 조사하였으며 최적조건을 도출하였다. 왕수농도 100 vol.%, 반응온도 $100^{\circ}C$, 반응시간 60분에서슬러지의 광액농도가 400 g/L에 도달할 때 까지 슬러지로부터 코발트의 완전한 추출이 이루어졌으나, 슬러지에 존재하는 모든 탄화텅스텐이 텅스텐산으로 완전히 전환되는 것은 광액농도가 150 g/L 이하일 때 이었다. 생성된 텅스텐산을 암모니아 용액에 용해함으로서 금속 불순물들을 불용성 잔사로 제거하는 것이 가능하였다. 증발결정 공정을 통하여 정제된 암모늄 텅스테이트 용액으로부터 99.85%의 순도를 가지는 암모늄 파라텅스테이트($(NH_4)_{10}{\cdot}H_2W_{12}O_{42}{\cdot}4H_2O$)를 얻을 수 있었다.

김지혜,이인석,Kim, Jihye,Lee, Inseok 대한인간공학회 2017 大韓人間工學會誌 Vol.36 No.5

Objective: The objective of this study was to measure the upper-limb motions and postures of grapes-harvesting tasks using electrical goniometers and analyze the upper-limb motions in a kinematic way to assess the risk of musculoskeletal disorders. Background: Grapes farmers are exposed to various risk factors of musculoskeletal disorders (MSDs) such as repetitive upper-limb motions, non-neutral postures, and manual handling of heavy items. The farmers have to use scissors repetitively while harvesting grapes with their being arms elevated over the shoulder height, which presumed to increase the physical workload. It has been reported that the grapes farmers feel the harvesting task as the one of the hardest work in cultivating grapes. We tried measure the wrist and elbow angles while the farmers were carrying out harvesting tasks to understand how much workload the work impose on the farmers, which can be helpful in making interventions of preventing musculosksletal disorders among grapes farmers. Method: We measured joint angles at the right wrist and elbow with a wireless measuring system with two electrical goniometers from five grape farmers. The grapes-harvesting task was classified into 6 different subtasks: 1) searching, 2) picking, 3) cleaning, 4) carrying, 6) storing, and 7) miscellaneous tasks. The subtasks were compared by mean angles, 10%, 50%, and 90% APDF values of wrist flexion/extension, ulnar/radial deviation, and elbow flexion. Results: The Kruskal-Wallis tests showed that the 10th percentiles of APDF of ulnar/radial deviation and flexion/extension of the wrist significantly differs among subtasks (p<0.05). It was found that the farmers assumed more deviated wrist postures in the ulnar direction when they picking and adjusting the grapes. The use of scissors seemed to force the farmers to severely bend their wrist in the directions of ulnar deviation and flexion. The grapes-harvesting task showed similar wrist postures and motion with poultry deboning and milking tasks. Conclusion: The grapes harvesting tasks make the farmers take ulnar deviated and extended postures in the wrist. The use of scissors makes them take more severely deviated postures in the wrist. Safety guidelines including use of ergonomic scissors can be provided to the farmers to improve their work conditions. Application: The results of this study can be used as a basic data for the development of safety guidelines for agricultural work.

In this study, whole crop rice samples were used to develop near-infrared reflectance (NIR) equations to estimate six forage quality parameters: Moisture, crude protein (CP), neutral detergent fiber (NDF), acid detergent fiber (ADF), Ash and relative feed value (RFV). A population of 564 whole crop rice representing a wide range in chemical parameters was used in this study. Undried finely chopped whole crop rice samples were scanned at 1 nm intervals over the wavelength range 680-2500 nm and the optical data recorded as log 1/Reflectance (log 1/R). NIRS calibrations were developed by means of partial least-squares (PLS) regression. The correlation coefficients of cross-validation (R²_cv) and standard error of cross-validation (SECV) for whole crop rice calibration were 0.98 (SECV 1.81%) for moisture, 0.89 (SECV 0.50%) for CP, 0.86 (SECV 1.79%) for NDF, 0.89 (SECV 0.86%) for ash, and 0.84 (SECV 5.21%) for RFV on a dry matter (%), respectively. The NIRS calibration equations developed in this study will be useful in predicting whole crop rice quality for these six quality parameters.

Objectives: In this study, the tongue features of patients with functional dyspepsia (FD) were compared with those of healthy controls. Methods: This prospective, case-control study was conducted on patients with FD and controls recruited at a single center. After screening, the subjects were allocated to the patient or control groups (patients=42, controls=40). Tongue images were acquired using a computerized tongue image acquisition system (CTIS). An independent t-test was conducted to compare the measurements from patients and controls. Binary logistic regression was performed to determine significant differences between the two groups after adjusting for age and sex. Results: The CIE $a^*$ color value in the tongue coating area was significantly lower in the patients with FD than in the controls (p=0.001). The tongue coating ratios were also significantly higher in the FD group than in the control group (p=0.003). We found that the CIE $a^*$ color value in the tongue coating area and the tongue coating ratios were significant predictive factors in both groups, based on binary regression analysis (p=0.016, 0.044, respectively). Conclusions: This study found that FD was significantly associated with CIE $a^*$ color value in the tongue coating area and tongue coating ratios. We suggest that these factors could be used as objective indicators of FD.
