Purpose : The purpose of this study was to apply manual lymphatic drainage (MLD) and high-frequency diathermy (HFD) to patients with axillary web syndrome (AWS), one of the side effects of breast cancer surgery, and to treat upper extremity pain, volume, function of the upper extremity, (joint range of motion; ROM, disabilities of the arm, shoulder and hand; DASH) and quality of life before and after treatment. It is to determine the effect of treatment by checking the level change. Methods : This study is a case series. A total of 5 patients diagnosed with AWS after breast cancer surgery voluntarily participated in this study. The intervention program consisted of stretching, MLD and HFD. It was conducted 3 times a week for 30 minutes for 4 weeks. In order to compare the effects of pain (numeric pain rating scale; NPRS), volume, upper limb function (ROM, DASH) and quality of life (the European organization for research and treatment of cancer quality of life questionnaire-breast, EORTC QLQ-BR23) evaluations were compared before and after 4 weeks of intervention. All measured variables were analyzed and expressed as mean, standard deviation and percentage. Results : The shoulder NPRS level of the subjects in all case groups decreased, the volume decreased and the shoulder flexion, abduction ROM increased. It showed improvement in DASH and quality of life, QLQ-BR23. Conclusion : After breast cancer surgery, we confirmed the possibility that MLD and HFD treatments could be effective in improving pain, decreasing volume, increasing upper extremity function, and quality of life for patients who have difficulties with AWS. The possibility has been confirmed, and additional research is needed by increasing the number of participants in the experiment in the future.

Objectives : The acupoint TE11 (cheongnaengyeon; CNY) firstly appeared in the ≪A-B Classic of Acupuncture and Moxibustion (AB Classic)≫. The name CNY is known to be originated from an ancient deep pool described in the book of ≪Chuangtzu (Jangja in Korean)≫. Description of the name, however, was not found in a single form in the book of ≪Chuangtzu≫ and its annotated books which made a confusion. The aim of the present study is to review the name of TE11 in terms of its origin. Methods : We have compared printed editions of ≪Chuangtzu≫ and its annotated books and various acupuncture classics including ≪AB Classic≫, ≪Essential Prescriptions Worth a Thousand Gold for Emergencies (Essential Prescriptions)≫, ≪Illustrated Manual of Acupuncture Points of the Bronze Figure (Illustrated Manual)≫, ≪Collection of Gems of Acupuncture and Moxibustion (Collections of Gems)≫, and ≪Complete Compendium of Acupuncture and Moxibustion (Complete Compendium)≫. Results : The name of ancient deep pool was found in two different forms in the book of ≪Chuangtzu≫ and its annotated books. One was CNY, the other was Cheong Ryeong Yeon (CRY). The description in the ≪Chuangtzu≫, the source book, was CRY. In addition, the acupoint TE11 was described as CRY in the ≪AB Classic≫, Cheong Ryeong Cheon in the ≪Essential Prescriptions≫. Meanwhile, the point was described as CNY in the ≪Illustrated Manual≫, the ≪Collections of Gems≫ and the ≪Complete Compendium≫. Conclusions : Data suggest that the original description was CRY and a mix of CNY and CRY as a name of TE11 was used. The Korean standard name of TE11 should be changed as CRY.

Concerns regarding work and food safety in foodservice operations are growing. The purpose of the study is to suggest guidelines for designing foodservice facilities, including school foodservices and Korean restaurants. A case of a franchise restaurant specializing in a Korean food item, Seolleongtang, was used to explain the facility design. The contents of the manual included ways to determine space allocation, calculate the application of utilities and the diameters of supply utility pipelines, and suggestions on how to decide on air conditioning equipment. The standards of the American Gas Association and the Japan Foodservice Equipment Association (JFEA) were applied to design the restaurant space. The JFEA standards and knowledge based on experience and statistics were applied to calculate the usage of utilities like fuel and water. The standards of JFEA and the Society of Heating, Air-Conditioning, and Sanitary Engineers of Japan were applied to calculate the diameters of the water supply and drainage pipelines. For the setting of the heating, ventilation, and air conditioning systems, three ways to carry out the calculation of effective ventilation were explained, as well as options to dicide the standard parameters of the duct and ventilation fans. This manual can contribute to the design of effective and efficient foodservice facilities and help secure the work safety of foodservice employees thereby ensuring food safety.

임상 실험실에서의 망상 적혈구 계산은 현재 수동 및 자동으로 구분된다. 현미경에 의한 망상 적혈구 수 검사는 정확성의 결여, 낮은 재현성 등이 망상 적혈구 결과의 정확성에 문제가 있다. 또한, 자동 혈액 분석기의 유동 세포 계측법은 개발 도상국 및 소규모 실험실에서 비용 때문에 사용하기가 어렵다. 따라서 본 연구는 이러한 단점을 보완 할 수 있는 새로운 방법을 찾기 위해 노력했다. 이 연구의 목적은 분광 광도계로 염색 된 망상 적혈구 수를 비교하고 또한 분광 광도계 및 유동 세포 계측기의 통계를 분석하는 것이다. 동일한 8 개의 EDTA 샘플을 36 회 반복하여 분광 광도계와 유동 세포 계측기 사이의 일치도를 비교 하였다. 이 연구는 700~780 nm에서 600 배 희석 한 표본을 10 개의 차이로 측정하였다. 흡광도에 의한 710~730 파장은 표준 및 검사와 양의 상관 관계가 있으며(r=0.967, p<0.01), 변수에 대한 상관 관계를 나타내었다. 결과에 대한 회귀 분석결과 최적 희석 계수는 600 배였다. 따라서 본 연구는 자동 분광 광도계를 이용한 망상 적혈구 흡광도 측정에 대한 경제적인 기여 그리고 망상 적혈구 관련 빈혈에 대한 모니터링 시스템 등에 기여 할 수 있는 기술적 활용을 시도한 것이다. 따라서 더욱 광범위한 연구가 필요할 것으로 사료된다.

In order to provide an effective preparedness for a nuclear or radiological emergency happening in the domestic or neighborhood countries and to solve the vague fear of the people for the ingestion of radioactive livestock products, the establishment of national guideline level for radionuclides in feed is urgently necessary. This is because it is important to secure the safety and to manage the crisis in the agricultural, fishery and food sector by performing the effective safety control during and after nuclear incident. This study was performed to investigate the report cases of international organizations and foreign countries to set up a domestic control standard for managing radioactive substances that may be contaminated in animal feeds due to the nuclear power plant incident. In addition, an attempt was made to provide a useful reference that can help prepare a domestic control standard, using a coefficient that can consider the transfer into livestock through the intake of radioactive contaminated animal feeds. The standard radioisotopes investigated were confined to radioactive cesium ($^{137+134}Cs$) and iodine ($^{131}I$). Guideline level for the radionuclides was calculated by using the transfer coefficient factor and the maximum daily intake of animal feed provided by IAEA. For example, the maximum daily intake of animal feed was set as $25kg\;d^{-1}$ for dairy cows, $10kg\;d^{-1}$ for beef cattle, $3.0kg\;d^{-1}$ for pigs and $0.15kg\;d^{-1}$ for chickens. The result values for radioactive cesium were calculated as $8,696Bq\;kg^{-1}$, $4,545Bq\;kg^{-1}$, $1,667Bq\;kg^{-1}$ and $2,469Bq\;kg^{-1}$, respectively. The results for radioactive iodine showed the ranges between $741Bq\;kg^{-1}$ and $76,628Bq\;kg^{-1}$. These data can be utilized as a scientific reference for the preparation of a crisis management manual for the emergency control due to nuclear power plant accident in Korea and neighboring country. These results will contribute to establish the safe feed management system at national level as manual for responding the radioactive exposure of agricultural products and animal feeds, which are currently not established.

To enforce the maximum residue limit for residual hexane (0.005 g/kg) in commercially available Korean vegetable oil, convenient and accurate quantification methods were investigated. Using dual surrogate standards, pentane and heptane were dissolved in ethanol, and then added to hexane-tree sunflower oil for setting up the calibration curve. Gas Chromatograph-Flame Ionization Detector with a porous layer open tubular column, indicated good chromatographic separation of hexane from other inhibiting matrix components. The lowest calibration level was $0.5\;{\mu}g/g$, not exceeding a relative standard deviation of 10% (RSD%), and 1.0\;{\mu}g/g$ not exceeding a deviation of 22% RSD% using heptane as an internal standard for the Static headspace analysis by using a headspace auto-sampler and manual injection, respectively. The residual hexane was detected in nine of the samples among 87 vegetable oil samples purchased on the local market.

This paper shows survey result on safety management status of laboratories in Korea. In Korea, many studies and reports on laboratory safety have been published since the ministry of education, science and technology (MEST) enforced the Act on Establishing a Safe Environment of Laboratories (Lab Safety Act) in 2006. The MEST has surveyed status of safety management in institutions subject to Lab Safety Act in 2008 and 2010. According to the survey result, safety management status of universities and colleges has been improved on several factors such as establishment of safety manual and implementation of safety inspection; while the number of safety managers of universities and colleges have increased. However, the difficulties in performing duties of safety managers has increased because the number of exclusive safety managers has decreased. This paper identifies the similarities and differences between Occupational Safety and Health Act and Lab Safety Act on assignment and duties of safety managers; therefore, this paper suggests a standard to determine the number of safety managers and decide whether or not their duties should be exclusive. Besides current standard that is based on the number of researchers, the number of individual laboratories should be considered. The new method would be helpful to determine the number of exclusive safety managers because the amount of safety managers' duties generally do not depend on only the number of people who may be exposed to any risk but also the number of facilities that may be cause of any accident.

PURPOSES : This study estimated an asphalt pavement internal behavior under uphill lanes considering reducing speed of heavy truck on uphill slope. METHODS : Truck performance curve which has been adapted to "Korea Highway Capacity Manual" was analyzed. And asphalt pavement internal behaviors were estimated with Multi-layered elastic analysis using KPRP(Korea Pavement Research Program) dynamic modulus prediction equations. RESULTS : As a result, it is shown that when the standard truck drives 2.0 km at a speed of 80 km/h in 8% climbing slope, it's speed reduced to 25.4 km/h, at same time frequency in asphalt layer decrease to 67.2% and it's dynamic modulus degrades to 30.9%. Based on these results, internal behavior as decreasing vehicle speed on uphill lanes were estimated. CONCLUSIONS : From the results of Multi-layered elastic analysis, internal behavior showed that when the standard truck drives 2.0 km at a speed of 80 km/h in 8% slope on uphill lanes, vertical strain was increased to 44.4% at the bottom of surface course, and lateral tensile strain was increased to 20.5% at the bottom of base course.

Mosts of export/import cargo has been moving using maritime transport means. Korea had been driven the system automation project using EDI document since the mid-1990s. However, this automation system comes upon about 40-50% against overall maritime business process, manual or paper document processing work is existing as ever. International e-business environment also has changing into electronic form document transaction from paper document-based transaction. International standardization organization, UN/CEFACT proposed UNeDocs for paperless jtransaction. UNeDocs is a specification to define XML data model as well as electronic form. With UNeDocs, it is not necessary to generate the duplexed data, and it can support user convenient and guarantee the flexibility. This paper defines the UNeDocs data model for EDI and Off-Line processing at the current maritime business. Then, it have to check XML syntax and structure for the defined data model through quality of document check system. Also, it explains the applying plan about the defined UNeDocs data model. It is possible to support paperless transaction as defining UNeDocs-based standard data model and converting into paper document, XML and EDI document using UNeDocs data model.
