This study was done to determine differences in effect of postoperative pain control in patients receiving auricular electroacustimulation vs transcutaneous electrical nerve stimualtion following total knee replacement surgery. Thirty-one cases referred to physical therapy department after treated by total knee replacement surgery by orthopedic surgery department at the Pohang St. Mary's Hospital from January 1993 through June 1994. Of 31 total knee replacement cases, 13 cases were auricular electroacustimulation group, 11 cases were transcutaneous electrical nerve stimulation group, and 7 cases were control group. The results of the study summerized are as follows: Thirty-one total knee replacement cases(male in 12 cases, female in 19 cases), ranging in age from 34 to 61 years(mean${\pm}$SD=49.90 7.56) with diagnoses of degenerative arthritis(20 cases), rheumatoid arthritis(9 cases), and other(2 cases). In auricular electroacustimulation group, there was a significant change of pain intensity, unpleasantness, and active range of motion after treatment(p<0.01). In transcutaneous electrical nerve stimulation group, there was a significant change of pain intensity, unpleasantness, and active range of motion after treatment(p<0.01). In control group, did not show significant pre-posttreatment differences in pain intensity, unpleasantness, active range of motion(p>0.05). The mean change in pain intensity and unpleasantness, active range of motion from pretreatment baseline for the 3 groups. Auricular electroacustimulation group showed the large magnitude of increase in pain intensity and unpleasantness, active range of motion when compared to its own pretreatment cycle. Transcutaneous electrical nerve stimulation group showed small magnitude of increase in pain intensity and unpleasantness, active range of motion when compared to its own pretreatment cycle. No significant changes were observed in control group. Highly significant differences in pain intensity, unpleasantness, and active rage of motion were found using an ANOVA measures between treatment groups and control group(p<0.01). The squares correlation coefficients of pain and function measures pretreatment-posttreatment differences for each group. In treatment group, there was significant correlation between pain scale and function(p<0.001). In control group, there was no correlation between the pain scale and function (p>0.05). The continuous study is needd for many interesting issues of auricular electroacustimulation in new future.

In adhesive capsulitis of the shoulder of no response to nonoperative treatment, an arthroscopic capsular release and manipulation improves range of motion and pain relief. We performed an arthroscopic examination in the stiff shoulder, of which she had no response to nonoperative treatment, after the conservative treatment of a clavicular shaft fracture by motorcycle-driver traffic accident. We found the intra-articular 'rotator interval bridging scar adhesion' between subscapularis tendon and antero-superior glenoid fossa under the rotator interval which was no adhesion and contracture itself. We performed the scar adhesion removal and synovectomy, maintaining the rotator interval. We recommended nonsteroidal anti-inflammatory drug for postoperative pain relief and continuous active and passive range of motion (ROM) exercise to gain motions. Preoperatively, active and passive range of motion were 70° for forward elevation, 60° for abduction and especially 0° for external rotation. After postoperative 2 months, active ROM were 150° for forward elevation, 130° for abduction and 80° for external rotation. After postoperative 6 months, passive and active ROM were full. UCLA score improved from preoperative 9 points to postoperative 29 points.

The purpose of this study was to apply the joint mobilization technique to the level of segments with pain and to the level of segments with hypomobility respectively and compare the immediate effects of the joint mobilization technique on the pain, the active cervical range of motion (ROM), and treatment satisfaction of patients with acute mechanical neck pain. After the baseline assessment, forty-two patients were randomized into two groups: a painful group ($n_1=21$) that received joint mobilization at the most painful cervical spine level and a hypomobile group ($n_2=21$) that received joint mobilization at the most hypomobile cervical level. The patients received an intervention that applied unilateral posterior-anterior gliding for 5 minutes and two repetitions of 10 times of active extension motion with distraction. In the Wilcoxon signed-rank test, the painful group and the hypomobile group were improved significantly in all pain variables (p<.001), while the painful group was improved significantly in the active cervical flexion (p<.001), extension (p<.001), left side-bending (p<.01), right side-bending (p=.001), left rotation (p<.001), and right rotation (p<.001). The hypomobile group was significantly improved in active cervical flexion (p=.001), extension (p<.001), left side-bending (p<.05), right side-bending (p=.001), left rotation (p=.001), and right rotation (p<.01) after intervention. In the Mann-Whitney U test, there was no significant difference in any of the dependent variables after the intervention between the two groups, but the painful group was slightly superior to the hypomobile group in all variables except for the right lateral flexion ROM and treatment satisfaction. These outcomes suggest that the cervical joint mobilization may be applied to either the level of painful segments or the hypomobile segments for the treatment of patients with acute mechanical neck pain.

Background Scalp defects may be caused by various etiological factors, and they represent a significant surgical and aesthetic concern. Various surgical techniques can be applied for reconstructive work such as primary closure, skin grafting, pedicled or free flaps. In this article, the authors share their clinical experience with scalp operations using the technique of local flaps and discuss the application of this method from the perspective of not only the size of the defect, but also in relation to the anatomical area, quality of surrounding tissue, and patient's condition. Methods During the period from December 2007 to December 2012, 13 patients with various scalp defects, aged 11 to 86 years, underwent reconstruction with local pedicle flaps. The indications were based on the patients' condition (age, sex, quality of surrounding tissue, and comorbidities) and wound parameters. Depending on the size of the defects, they were classified into three groups as follows: large, 20 to 50 $cm^2$; very large, 50 to 100 $cm^2$; extremely large, 100 $cm^2$. The location was defined as peripheral (frontal, temporal, occipital), central, or combined (more than one area). We performed reconstruction with 11 single transposition flaps and 1 bipedicle with a skin graft on the donor area, and 2 advancement flaps in 1 patient. Results In all of the patients, complete tissue coverage was achieved. The recovery was relatively quick, without hematoma, seroma, or infections. The flaps survived entirely. Conclusions Local flaps are widely used in scalp reconstruction since they provide healthy, stable, hair-bearing tissue and require a short healing time for the patients.

본 연구에서는 정수장에서 사용후 폐기된 활성탄을 전자파로 조사 capillary 복원 능력을 조사하였고 활성화제의 종류 및 량에 따른 비표면적 변화에 대하여 연구하였다. 수증기를 활성화제로 사용한 경우에는 재생의 능력은 우수하나, 폐활성탄에 함유하고 있는 수분과 반응하여 자동이송에 문제점이 있는 것으로 나타났다. 또한 $CO_2$ gas로 재생한 결과 이송의 문제점도 해결되고 비표면적도 신탄에 비해 10-20%향상된 것으로 나타났다. 전자파의 세기에 있어서는 2.75kw 공급시 제일 좋은 재생효과가 나타났다. 각 변수에 의한 실험 후 반응물을 ASAP, SEM등을 이용하여 분석한 결과 전자파의 세기와 활성화제 종류 및 양에 따라 복원 능력이 다르게 나타났다. 특히 공기를 활성화제로 사용한 경우에는 복원능력의 오차가 심하게 나타났다. 이는 전자파에 의해 활성탄이 가열된 상태에서 공기의 량이 과다하게 투입, 산화, 연소되어 수율이 떨어지는 것으로 확인되었다. Microwave를 이용하여 폐활성탄을 재생시킨 결과 일반적으로 사용하고 있는 rotary kiln보다 우수한 재생효과가 나타났고, 경제성에서도 앞서는 것으로 나타났으나 대량 생산이 어렵다는 것이 단점으로 나타났다.

Varing the flow velocity of solution and particle diameter, the mass transfer coefficient of the local electrode on current feeder has been measured in an empty flow reactor, an inert fluidized bed electrode reactor, and an active fluidized bed electrode reactor. It had its maximium value when the bed porosity was 0.6 to 0.65 and decreased with in- creasing the height of local electrode. The mass transfer coefficient was found to be high especially when higher particle was fluidized. Electrochemical deposition of copper dissolved in the synthesized wastewater has been performed in the active fluidized bed electrode reactor. The deduction rate was higher than 90% and the residual concentration of copper decreased to less than 5ppm.

This experiment was carried out to investigate the mixing ratio of soil amending materials such as peat perlite, active carbon and zeolite for improvements of physiochemical properties of topsoil, of creeping bentgrass (Agrostis palustris var. Penncross). The results were as followed :1.Appropriate addition of soil improvement material was increased the soil porosity due to the decrease of bulk density. Over supplement of soil improvement material induced the decrease of infiltration of water into soil.2Content of organic matter was increased in treatment of peat and active carbon . Soil reaction was decreased in peat treatment, but increased in perlite, zeolite and active carbon. Exchangeable cation capacity was increased by the addition of all kinds of soil improvement materials used in this experiment.

Antibody responses in serum and cerebrospinal fluid (CSF) samples from patients with active and chronic paragonimiasis and in sera from patients on whom follow-up studies were done after praziquantel treatment were analyzed using antigens of Paragonimus westermani prepared from eggs, metacercariae, juveniles of 4-and 7-week old, adult worms and recombinant protein of 28 kDa cruzipain-like cysteine protease (rPw28CCP). The patient sera/CSFs of active and chronic paragonimiasis revealed strong antibody reactions against the crude extracts of 4-and 7-week old juveniles as well as against those from egg and adult. rPw28CCP also showed specific reaction to the sera with active paragonimiasis. After the treatment, levels of specific antibodies in the sera gradually decreased to negative range in most patients. In some cases with persisting high antibody levels, however, the reactions at 27 kDa egg Protein were sustained throughout the observation period of 34 months. The reactions at 35 and 32 kDa in adult extract and rPw28CCP disappeared rapidly after the treatment. Persistent antibody reactions even after successful treatment are provoked by continuous antigenic challenge from eggs which were not resolved by treatment.

The role of the treatment for latent tuberculosis infection (LTBI) has been underscored in the intermediate tuberculosis (TB) burden countries like South Korea. LTBI treatment is recommended only for patients at risk for progression to active TB-those with frequent exposure to active TB cases, and those with clinical risk factors (e.g., immunocompromised patients). Recently revised National Institute for Health and Care Excellence (NICE) guideline recommended that close contacts of individuals with active pulmonary or laryngeal TB, aged between 18 and 65 years, should undergo LTBI treatment. Various regimens for LTBI treatment were recommended in NICE, World Health Organization (WHO), and Centers for Disease Control and Prevention guidelines, and superiority of one recommended regimen over another was not yet established. Traditional 6 to 9 months of isoniazid (6H or 9H) regimen has an advantage of the most abundant evidence for clinical efficacy-60%-90% of estimated protective effect. However, 6H or 9H regimen is related with hepatotoxicity and low compliance. Four months of rifampin regimen is characterized by less hepatotoxicity and better compliance than 9H, but has few evidence of clinical efficacy. Three months of isoniazid plus rifampin was proved equivalence with 6H or 9H regimen in terms of efficacy and safety, which was recommended in NICE and WHO guidelines. The clinical efficacy of isoniazid plus rifapentine once-weekly regimen for 3 months was demonstrated recently, which is not yet introduced into South Korea.

This stydy was performed to investigate the inhibitory effect of bovine milk on the atherosclerotic rats. Eighty male rats of 5-weeks of age were divided into 4 groups, control, active treatment control fed the atherogenic feed, and skim milk and whole milk groups fed powdered skim or whole milk mixed with the atherogenic feed and observed for 13 weeks. Growth, clinical and pathological changes of the rats were examined. Rats of the 4 groups did not show significant difference of feed intake and weight gain. The level of serum cholesterol, high density lipoprotein cholesterol (HDL-cholesterol) fraction, and inorganics between skim milk and whole milk groups were not significantly different though significant difference was shown between active treatment control and milk groups. Milder calcification and nearosis in aorta, heart and kidney and fat degeneration in liver were seen in the milk groups than were in active treatment control. Marked difference, however, was not found between the skim milk and whole milk groups. Both powdered skim and whole milks could have a helpful effect of vitamin D2-and -cholesterol-induced atherosclerosis in rats.
