The effect of heft treatment on the characteristic properties of insulation layer is studied for two kinds of non-oriented silicon steels, which were insulation-coates with various kinds of inorganic and inorganic-organic complex coating solutions. In addition, how the carbon contained in the insulation layer would affect the carbon content and the magnetic properties of the steel substrates is examined. Lower temperature heat treftment ($480^{\circ}C$ for 0.5hr) is found to render morw favorable surface qualities, wheras higher temperature heat treatment ($790^{\circ}C$ for 2hr) better core loss due to grin growt occurred during the heat treatment. Decarburization of the steel substrate is also found unaffectrd by the presence of carbon in the insulation layer.

The purpose of this study is to explore adolescent depression, increase understanding of social problems, and develop prevention and intervention strategies. As a research method, social big data was used to collect information related to 'youth depression', and related factors were identified through data mining and analysis of related rules. We used 'Sometrend Biz Tool' to collect and clean data from the web and then analyzed data in various languages. The study found that online articles about depression decreased during the school holidays (January to March), then increased from March to the end of June, and then decreased again from July. Therefore, it is important to establish a government-wide depression management monitoring system that can detect risk signs of adolescent depression in real time. In addition, regular stress relief and mental health education are needed during the semester, and measures must be prepared to deal with at-risk youth who share their depressed feelings in cyberspace. Results from these studies can be expected to provide important information in investigating and preventing youth depression and to contribute to policy development and intervention.

Objectives : MENS was used for wound healing and pain relief using bioelectric property. There are many articles on in vivo and clinical research. This article reviews articles on MENS published for recent 10 years to consider effectiveness of MENS and other fields to applicate MENS. Articles were collected from MAR, 2008 to JUN, 2008. Methods : We searched Pubmed, KSI, KERIS, KMBASE, and National assembly library using "Microcurrent Electrical Neuromuscular Stimulation" and classified the articles into subsets of foreign, Korean and wound healing, pain, relief, and increasing the range of movement(ROM). Also we evaluated their values according to the Jadad scale. Results : A total of 18 articles (Foreign-9, Korean-9) reconfirmed that MENS reduces pain, increases wound healing, ROM, and strength of muscle. In addition, MENS has effect on stress-hormone and various pain like low back pain, acute lateral epicondylitis, and plantar fascitis. And there are various styles developed. However, there is no standard protocol so the user is usually in trouble at clinic. Conclusions : MENS may be have application to various pain diseases, and further studies analysing its effectiveness are needed.

Bee venom acupuncture (BVA), as a kind of herbal acupuncture, involved injecting diluted bee venom into acupoints and is used for pain, osteoarthritis and rheumatoid arthritis patients. BVA is growing in popularity, especially in Korea, and is used primarily for pain relief in many kinds of diseases. However, the effect of bee venom anti-inflammatory related action in lipopolysaccharide (LPS) induced chondrocyte stress have not been reported yet. The aim of this study was to investigate the effect of bee venom of cell viability and inflammatory cytokine in rat articular chondrocyte cultures stimulated with lipopolysaccharide. Inflammation was induced in rat chondrocytes by treatment with $10{\mu}g/m{\ell}$ LPS. The change of cell viability were decreased in chondrocytes after treatment with lipopolysaccharide. The cell viability revealed that BV exerted no significant cytotoxicity in the rat chondrocyte. Bee venom inhibited decreased cell viability in the presence of lipopolysaccharide ($10{\mu}g/m{\ell}$) in a dose dependent manner(0.1, 0.5, 1.0 and $5.0{\mu}g/m{\ell}$) at bee venom(p<0.05). Tumor necrosis factor (TNF)-${\alpha}$ production in the presence of lipopolysaccharide($1{\mu}g/m{\ell}$) was also inhibited in a dose dependent manner (p<0.05 from bee venom $0.1{\mu}g/m{\ell}$). Interleukin (IL)-6 production in the presence of lipopolysaccharide ($10{\mu}g/m{\ell}$) was inhibited as well (p<0.05 at bee venom 0.1, 0.5, 1.0 and $5.0{\mu}g/m{\ell}$, respectively). Our results demonstrate that bee venom was a anti-inflammatory agent of chondrocytes. Bee venom may exert its anti inflammatory effects through inhibition of TNF-${\alpha}$ and IL-6 synthesis, and may then pain relief and reduce the articular destruction.

This study was carried out among 34 patients who visited Yonsei Dental Hospital from 1996. 1. to 1999. 5 for trigeminal neuralgia. By studying the patient's treatment prior to visiting our hospital, features of trigeminal neuralgia, treatment process of trigeminal neuralgia, prognosis of treatment, consultation with other professions and involvement of surgery, etc., the results are as follows: 1. 67.7% of onset age range from 40s to 60s, and average age is 50.2. 2. Ratio of right to left involvement is 1:2.1, male to female ratio is 1:1.9. 3. Occurrence rate of each branch is V3(44.1%), V2(11.8%), V1+V2+V3(11.8), V1+V2(8.8%). 4. Treatments prior to admission to our hospital are extraction(5.9%), endodontic treatment(5.9%), medication(11.8%), Oriental Medicine treatment(5.9%). 5. Routes of admittance to our hospital are by their preference(55.9%), local clinic referral(32.4%), E.N.T referral(5.9%), Neurology referral(5.9%). 6. 70.6% of patients treated at our hospital who were relieved of symptoms, were referred to Neurology(66.7%) and Pain Clinic(33.3%) for the reason of relapse, side effects of the drug itself, incomplete relief of pain. 7. 2 patients who were referred to medical part showed brain vessels contacting trigeminal nerve root on Brain MRangiography. But pain is being controlled by medication and no specific surgical procedure was carried out. The results show that 17.7% of patients admitted received inappropriate early treatment. In order to relieve tooth loss and patient's psychologic stress due to inappropriate treatment, precise differential diagnosis must be made among local teeth disease and idiopathic facial pain. Medication may show side effects of the drug itself, incomplete relief of pain or relapse of symptoms. Therefore, to treat trigeminal neuralgia appropriately by drug injection, surgery or radiation therapy, consultations among dentists, neurologists and anesthesiologists are required.
