Purpose：To investigate the effect of the home exercise program on pain, scoliosis, pelvic alignment of low back in chronic back pain patients, and suggest optimal method for home exercise program. Methods：I divided into two groups who has chronic back pain; one is control group who was given a treatment at the hospital only and the other is experimental group who did another exercise after treatment at the hospital, and there were 10 people in each group. The manual therapy were given to all the patients in each group after applying a stupe and an electric treatment, but the experimental group conducted another exercise program at homes. All the exercise programs were applied to patients 12 times for 4 weeks totally. Results：SPSS for win version 12 was used for statistic analysis and independent t-test was used to find changes between two groups. VAS scale was used to show changes in pain between each group. The grade of pain was decreased between pre&post test to -5.60 in control group and -4.80 in experimental group but there wasn't significant difference between each group. Cobb's degree was used to compare the changes of scoliosis in lumbar and it was improved in each group but there wasn't significant difference between each group. The measurement of pelvic misalignment was decreased between pre&post test to -1.00 in control group and -2.00 in experimental group but it wasn't enough to show significant difference between each group. Conclusion：As you read the results above, for a chronic low back pain patient, application of the manual therapy showed that it has effect on decrease of low back pain, improvement of scoliosis in lumbar and pelvic misalignment. However, the effect of home exercise treatment was not sure about improvements for chronic low back pain patient. So I think there should need further study about the effect of home exercise treatment except the treatments at hospital and the thorough education for the exercise of lumbar should be done before the study for the accurate experiment.

A critical pathway (CP) defines the optimal care process, sequencing and timing of intervention by multi-disciplinary health care teams for a particular diagnosis and procedure. It plays an important role as a cost-effective health care delivery system and a tool for quality control of medical and dental services by means of standardizing medical practices. The aim of this study is to investigate the satisfaction of patients and medical/dental staff after implementation of a critical pathway for dental treatment of disabled children under general anesthesia and its cost effectiveness. Ten patients who underwent dental treatment under general anesthesia were included in the CP group between August and December 2006. The pre-CP group included 20 patients who underwent the same procedure from February 2003. The satisfaction of parent of child patient and medical staff members were compared between two groups. The parents' satisfaction was significantly improved after the implementation of CP and medical/dental staff members were highly satisfied with the usefulness of the critical pathway. In conclusion, the critical pathway for the dental treatment of disabled treatment under general anesthesia can highly improve the satisfaction of parents and medical/ dental staff members.

심미란 단어가 우리에게 친숙한지 20여년이 흐른 지금도 새로운 것에 도전하듯이 어려움을 가져다주는 것은 아마도 진화라기보다는 기본적인 로드맵이 안 되어 있어서 아직도 서툴고 회피하는 것은 아닌지 싶다. 보철마다 특성상 장점과 단점이 있는 것이기에 그 적응증을 숙지하고 그에 맞는 진단과 적절한 선처치가 될 때 기대할만한 결과를 얻을 것이다. 이 과정에 환자에 대한 정보공유와 치과의사와 치과기공사간의 소통과 전문화된 각자의 역할은 매우 중요한 치료과정이며 이 통로를 얼마큼 잘 제도화 시켰느냐가 심미기공물의 성패가 달려 있다고 보아도 과언 이 아닐 것이다. 위의 서술한 치료과정의 바탕으로 가장 장점이 많고 보존적의미가 있는 라미네이트 심미보철에 관해 살펴보고자 한다.

상수도 공급을 위한 정수장에서 전염소 또는 중염소 공정이 도입된 수처리 공정의 염소농도 관리에 필요한 공정제어를 위하여 AI 기술을 활용한 수질예측 기법이 연구되고 있다. 본 연구에서는 정수장 수처리 공정에서 실시간으로 관측, 생산되고 있는 수량·수질자료를 이용하여 염소소독 공정제어 자동화를 목적으로 침전지 후단의 잔류염소 농도를 예측하기 위한 AI 기반 예측모형을 개발하였다. AI 기반 예측모형은 과거 수질 관측자료를 학습하여 이후 시점의 수질에 대한 예측이 가능한 기법으로, 복잡한 물리·화학·생물학적 수질모형과 달리 간단하고 효율적이다. 다중회귀 모형과 AI 기반 모형인 랜덤포레스트와 LSTM을 이용하여 정수장의 침전지 후단 잔류염소 농도를 예측하여 비교하였다. 최적의 잔류염소 농도 예측을 위한 AI 모형의 입출력 구조로는 침전지 전단의 잔류염소 농도, 침전지 탁도, pH, 수온, 전기전도도, 원수의 유입량, 알칼리도, NH₃ 등을 독립변수로, 예측하고자 하는 침전지 유출수의 잔류염소 농도를 종속변수로 선정하였다. 독립변수는 침전지 후단의 잔류염소에 영향이 있는 정수장에서 확보가 가능한 관측자료중에서 분석을 통해 선별하였으며, 분석 결과 연구대상 정수장인 정수장에서는 중회귀모형, 신경망모형, 모델트리 및 랜덤포레스트 모형을 비교한 결과 랜덤포레스트에 기반한 모형오차가 가장 낮게 도출되는 결과를 얻을 수 있었다. 본 연구에서 제시하는 침전지 후단의 적정 잔류염소 농도 예측값은 이전 처리단계에서 염소주입량의 실시간 제어가 가능토록 할 수 있어 수처리 효율 향상과 약품비 절감에 도움이 될 것으로 기대된다.

담액 수경재배에서 재배후반기 양액농도가 상추의 생장과 저장성에 미치는 영향을 구명하고자 4가지 양액농도(1/2S, 1S, 2S와 4S)를 '적치마'와 '청치마' 식물체에 처리한 후 생장과 수확후 특성을 조사하였다. 국화과 전용배양액($N-P-K-Ca-Mg=14.2-3.5-9-4-2me{\cdot}L^{-1}$)의 1배액으로 조성하여 3주간 재배한 후 2주간 양액 농도를 조절하여 재배한 결과 두 품종 모두 생체중 등의 생육량이 1배액이 좋았으며, 2배액과 1/2배액은 1배액보다 다소 떨어졌으며, 4배액에서는 생장 특성이 저하되는 것으로 나타났다. 색소 및 무기이온 함량에서는 4배액으로 처리한 상추가 높았다. 수확후 특성에서는 품종별로 2배액으로 처리한 상추가 저장기간 중 생체중 감소 및 SPAD 변화의 폭이 적었고, 외관과 같은 선도유지에 효과적인 것으로 나타났으며, 대체로 1배액, 1/2배액, 4배액 순으로 나타났다. 상추 수경재배 후기에 양액 농도교환에 따른 생육과 수확후 특성을 보면 재배 중에 최적의 생육량을 보인 양액 조성이 수확후 저장 및 품질유지 효과와 일관성을 보이지 않는 것으로 나타났다. 따라서 변화하는 농업 여건에 맞추어 수경재배에서 생산성 향상뿐만 아니라 향후에는 수확후 특성을 고려한 양액 조성과 재배 방법에 대한 개선이 필요한 것으로 보인다.

Objectives : Hypertension (high blood pressure), one of the world's major chronic diseases, has a high mortality rate due to its high prevalence and complications, but its control rate is low. The proper management and control through appropriate exercise, diet management, and optimal drug choice can reduce the risk of death from hypertension. Although various antihypertensive drugs are used to treat hypertension, they also have numerous adverse effects. Alongside increased interest in the use of Traditional Herbal Formulas (THF) for hypertension treatment, the purpose of this study was to examine the vasodilative effects of 10 THF in the rat thoracic artery pre-contracted by potassiumchloride (KCl). Methods : THF were extracted with distilled water for 2 hours. The rat thoracic artery was suspended and contracted by KCl in the organ bath which contained 10 ml Krebs Henseleit (KH) buffer. THF extracts were added in a dose-dependent increase (10-1,000 ㎍/mL) to examine vasodilative effects. The vasodilative effects produced by THF were expressed as the percentage in response to KCl-induced contraction. Results : Among the 10 THF, Banhasasim-tang, Buhnsimgieum, Sagunja-tang, and Samul-tang showed vasodilative effects. And, Sipjeondaebo-tang, Ssanghwa-tang, Ojeok-san, Onkyung-tang, Yongdamsagan-tang, and Hyangsayukgunja-tang showed no significant vasodilative effects. Also, in co-administration with amlodipine, Banhasasim-tang showed higher vasodilative effects than amlodipine alone, and Buhnsimgieum showed greater vasodilative effects at low concentrations, but inhibited amlodipine's vasodilative effects at high concentrations. Conclusion : As a result of these studies, they will be expected to provide useful data to establish guidelines of combined administration of THF and western antihypertensive drugs for the treatment of hypertension.

This study attempted to establish the optimal conditions for storage of spring kimchi cabbage to stably control supply and demand. To this end, this study stored kimchi cabbages in various manners for different periods and compared the quality characteristics of kimchi using these cabbages. According to the results, pre-drying with photocatalytic and pre-cooling treatments showed average selectivity loss rates of 18.83 and 21.37%, respectively, which were lower than those of other treatments. Spring kimchi cabbages were stored for 15 weeks under various conditions, and the kimchi was stored for 4 weeks at $4^{\circ}C$. After ripening, each kimchi was analyzed for their soluble solid content, pH, acidity, and salinity. The average pH of kimchi was 4.60 and tended to rise, whereas average acidity was 0.38% and fell by 0.24 to 0.31% as the storage period was extended. Extension of the storage period caused decreases in soluble solid content and salinity, and the number of lactic acid bacteria decreased due to increased pH and reduced acidity (p<0.05). Sensory evaluation showed that all experts and non-professionals preferred kimchi treated by precooling compared to any other treatment.

This study aimed to develop a new dust collecting system equipped with an activated carbon (A.C.) coated electrode. Before fabrication, pre-treatment of A.C. was performed to remove metal ions within the A.C. to enlarge its specific surface area. Then, pre-treated A.C., black carbon, polyvinyl acetate (PVAc), and methanol were mixed to make a gel compound, which was coated onto aluminum plates to fabricate electrodes. The optimal mixing ratio of A.C., black carbon, PVAc, and methanol was found to be 10 g: 2 g: 3 g: 20 mL. After fabrication, the electrodes were used in the batch-type experiment for $NH_3$ and $H_2S$ removal. The reduction rates of the gases were high at the beginning and slowly reduced with time. Dust collection experiments were conducted in continuous flow, with various voltages applied. Compared to 5 kV, dust removal efficiency was 1.5 times higher when 10 kV was applied. Increasing the number of electrodes applied also increased the collecting efficiency. The correlation coefficient between actual collecting efficiency and trend line was higher than 99%. Consequently, the novel dust collection system equipped with A.C. coated electrode appears to be a promising substitute for existing dust-control devices.

To improve accuracy of the immunohistochemical testing and fluorescence in situ hybridization (FISH) study as well as a routine histology diagnosis in breast cancer, quality improvement for optimal tissue handling is mandatory. We evaluate fraction defective of 7107 blocks from 349 breast cancer patients, who underwent surgical treatment at Samsung Medical Center Seoul, Korea from January 1, 2009 to March 31, 2010. We decided pre-improvement period from January, 2009 to June, 2009. In the first quality improvement period (July, 2009 to September, 2009) we made improvements in protocol of gross examination. In the second quality improvement period (October, 2009 to December, 2009) we attempted more effective formalin fixation such as frequent exchange of formalin and use of separate fixation container for each case. In the third quality improvement period (January, 2010 to March, 2010) improvement of tissue processor was performed. We achieved a marked reduction of fraction defective (9-16%) through efforts to improve quality of formalin-fixed, paraffin-embedded blocks when compared to pre-improvement period.
