Objective : The authors introduce a minimally invasive muscle sparing transmuscular microdiscectomy (MSTM) to treat herniated lumbar disc disease. Its results are compared with conventional subperiosteal microdiscectomy (CSM) to validate the effectiveness. Methods : Muscle sparing transmuscular microdiscectomy, which involves muscle dissection approach using the natural fat cleavage plane between the multifidus to expose the interlaminar space, was performed in 23 patients to treat a single level unilateral lumbar radiculopathy. The creatine phosphokinase (CPK)-MM serum levels were measured on admission and at 1, 3, and 5 days postoperatively. Postoperative pain was evaluated using a 10-point visual analogue scale (VAS) and recorded on admission and at 1, 3, and 5 days postoperatively. The results were compared to those from the conventional subperiosteal microdiscectomy (43 patients). Results : The CPK-MM levels were significantly lower in the serum of the MSTM group compared to the CSM group on postoperative days three and five (p = 0.03 and p = 0.02, respectively). The clinical scales for back pain using VAS were significantly lower in the MSTM group than in the CSM group on postoperative days three (p = 0.04). The mean VAS scores for leg pain in both groups showed no significant differences during the early postoperative period. Conclusion : Muscle sparing transmuscular microdiscectomy is a minimally invasive surgical option to treat lumbar radiculopathy due to herniated disc. The approach affected minimal injury to posterior lumbar supporting structures with alleviated postoperative back pain.

Gyeongoggo is first described in the Collected Prescription by Hong Family in the Song Dynasty in China. It is composed of Radix Rehmnniae, Panax ginseng, Poria cocos, and Mel. Its main efficacy is to treat weakness of primordial essence of body and dry cough, and to invigorate qi and replenish yin principle. It is one of the most important prescriptions that people have been using for a long time. We studied the documents recorded in the medical classics and comprehended the following results. Gyeongoggo has efficacy to keep a person healthy and live long age, to treat amnesia and dizziness from brain weakness, to strengthen muscle and bone by improving function of stomach and colon, to improve a person's memory and judgement, to invigorate brain weakness, and, to treat tuberculosis and lung cancer. The longer a person take it, the better it is for one's health and meditation. When it is made, it is important to mix four components up, to boil it with an oak tree for three days and nights, and then to add water from a well to reduce heat for a full day, and to boil up again for a full day to mature fully. As gyeongoggo is acquired not only by the full heart of a manufacturer but also the sympathy of nature, it is important to choose a clean place to make and keep. When it is taken, it is proper to take it with warm water or liquors. And when it is made, we came to know that it is possible to make gyeongoggo with special efficacy by adding one to three more components.

Objectives : This survey was accomplished to find out how Korean medical doctors take acupuncture treatment in real clinics. Methods : The survey questions were developed by the consensus from the professors who major in acupuncture and moxibustion. The questionnaire was given the 2731 Korean medical doctors at the mending education site; In addition, it was given to 793 doctors working at the 105 Korean medical hospitals listed on the National Korean Medical Hospital Associations Address book by postal mail; and also it was given to the 142 public health care Korean medical doctors who attended the conference for the municipal and provincial representatives of the public health service Korean medical doctors. Total of 1277 questionnaires were retrieved out of the 3666 subjects. Results : 1. Nine hundred out of 1277 Korean medical doctors used method of differentiation syndromes(70.4%) and 1184 out of 1277 Korean medical doctors convalescence decide with subjective symptom improvement of patient(92.6%). 2. Nine hundred eight out of 1277 Korean medical doctors used both local and remote points(71.0%) and 916 out of 1277 Korean medical doctors treat with method of reinforcement-reduction(71.7%). 3. Eleven hundred fifth five out of 1277 Korean medical doctors used cupping a boil(90.3%) and 1023 out of 1277 Korean medical doctors used moxibustion(80.1%). Conclusion : When Korean medical doctors treat with acupuncture, most of them diagnose with differentiation methods and meridian theory, decide convalescence with subjective symptom improvement of patient, select out of both local and remote acupuncture points, treat with method of basic reinforcement-reduction, apply moxa and cupping a boil when they are necessary. The cupping a boil comes to be used when being muscle and joint disease. The moxa comes to be used when being chronic disease.

철도에서 유래한 중금속 오염 토양을 정화하기 위해 세척방법의 타당성을 연구하였다. 유기산과 무기산을 사용하여 중금속 세척효율을 비교한 결과 무기산이 유기산보다 우수한 효과를 나타내었다. 일반적으로 세척효율이 우수하다고 알려진 ethylene diamine tetraacetic acid (EDTA)는 본 오염 토양의 세척에는 효과적이지 않았다. 무기산 중에는 HCl이 제일 우수한 효과를 보였으나, 세척효율은 0.5 M 에서도 30% 수준이었다. 특히 Zn와 Ni의 제거율이 다른 중금속에 비해 낮았다. 이는 Zn 와 Ni의 토양오염공정시험방법 상의 분석법이 왕수 추출에 의한 전함량이기 때문에 더 낮은 것으로 사료된다. 다른 중금속은 비교적 높은 70% 이상의 세척효율을 얻을 수 있었다. 결과적으로 단순한 세척공법은 중금속 유래 철도오염 토양을 처리하는데 적합하지 않다.

This research presents results from laboratory and pilot-scale experiments to remove high-nitrate in pickling wastewater using the sequencing batch reactor (SBR) as a biological method. During the experimental periods, the influent concentrations of NOx-N and $Ca^{+2}$ were analyzed to be 350-1,600 and 700-800 mg/L, respectively. In order to provide carbon source for denitrification, methanol has been added in proportion to the influent nitrate loading. The mean concentrations of MLSS and MLVSS, the fraction of volatile solids in sludge and the sludge volume index were measured to be 27 g/L, 5 g/L, 18.5% and 7.5, respectively. The solid retention time was kept in the range of 18 to 22 days, specific denitrification rate ($U_{dn}$) was $0.301g{NO_3}^--N/gVSS/day$. The oxidized nitrogen concentration of effluent ranged 2-34 mg/L with an average of 5.2 mg/L, the overall reduction in total nitrogen was more than 99.2%. In order to treat the pickling wastewater including the high concentration of nitrate and $Ca^{+2}$, the continuous flow process is not suitable because the specific gravity of the sludge is considerably increased by $Ca^{+2}$, thus the SBR process is shown to be very effective to treat the pickling wastewater.

Development of shale gas has drawn increasing attention since it is one of promising alternative energy resources. However, contamination of groundwater and surface water during the extraction of shale gas is becoming a serious environmental issues, which brings the needs to treat wastewater generated from hydraulic fracking. In this study, the feasibility of membrane distillation (MD) for the treatment of shale gas wastewater was investigated using a laboratory scale experimental setup. Flat-sheet MD membranes were used to treat produced water from a shale gas well in the United States. Different configurations such as direct contact MD (DCMD) and air gap MD (AGMD) were compared in terms of flux and fouling propensity. The foulants on the surface of the membranes were examined. The results suggest that MD can treat the shale gas produced water containing more than 200,000 mg/L of total dissolved solids, which is impossible by other technologies such as reverse osmosis (RO) and forward osmosis (FO). In this study, we investigated the possibility of processing and characterization of shale gas produce wastewater using membrane distillation. Laboratory scale membrane distillation experimental device was developed. It was compared the flat-sheet direct contact membrane distillation and flat-sheet air gap membrane distillation. AGMD flux in lower than the flux of DCMD, it was expected that the contamination caused by organic matters.

This study examined food sharing characteristics revealed in the modern Korean society by both interpreting phenomena and analyzing literature. Diet was said to be the least influenced by western modernization in Korea. Concerning this matter, one of the important explanations to be considered would be a strong influence of 'the first settlement effect' in culture, as reviewed elsewhere. Sharing food means not only sharing food itself but also sharing communal solidarity. The latter was strongly emphasized in Korean food culture due to his own historical grounding. Some examples revealed in current Korea included sometimes too much generous treat when eating out, even saliva allowed food sharing, too much food provision, and too many restaurants. 'Dutch treat' observed in many occasions of food sharing in Korea was also viewed as a product of historical experience, which was related to the degree of traits of feudalism in modern societies as feudalism was based on a sort of a give and take contract. The association of the degree of traits of feudalism and communal solidarity was explored by comparing so called different meal treat manners between Koreans and Japanese, that is, more generous attitude among the former. The concept of communal solidarity was also examined with respect to Koreans' side dish sharing behaviors which sometimes accompanied seemingly insanitary saliva sharing. In addition, provision of too much food was analyzed by relating this manner to a traditional 'hand over dining table' custom. Traditionally, food on a dining table was not supposed to be only for those sitting on the table. Even though the 'hand over dining table' was no longer well preserved at present time, its cultural traits appeared to be well prevailed in the modern Korean society. Finally, an increase of restaurants as well as an increase of eating out occasions were postulated with respect to the notion that restaurants were the places for ascertaining communal solidarity while sharing foods. The above analyses suggest the importance of the influence of sharing originated from his/her own historical grounding for better understanding of modern Korean food culture.

It is necessary to decide the pumping rate and pumping well location together with the capture zone in order to determine an appropriate groundwater remediation strategy to manage the contaminated groundwater. The relationship between the capture zone and the drawdown radius of influence ($ROI_s$) was considered. $ROI_{cs}$ is defined as the distance where the criteria of drawdown is cs meter from pumping well in this paper. A method to decide the required pumping rate for the remediation of contaminated groundwater in order to create appropriate $ROI_{cs}$ is suggested by using the Theis equation (1935) and Cooper-Jacob equation (1946). It was shown in this study that $ROI_{cs}$ is in proportion to the pumping rate and the criteria of drawdown, which decides $ROI_{cs}$, is inversely proportional to Ti value (transmissivity ${\times}$ hydraulic gradient). The pumping rate which creates the required $ROI_{cs}$ could be planned through the relationship between the $ROI_{cs}$ and pumping rates ($ROI_{cs}$-Q curve) of the field sites 1, 2 and 3. If the drawdown is investigated along with Ti value and pumping rate at a specific site where pump and treat remediation is planned, it is expected that the required criteria of drawdown can be evaluated by using the relationship between the cs and Ti (cs-Ti curve).
