Downhole seismic method is very economic and easy of operation because it uses only one borehole and simple surface source to obtain the shear wave velocity ($V_s$) profile of a site. Even though it is widely used by the site investigation companies, universities and institutes, however, the $V_s$ profile determined by downhole seismic method has often low reliability due to employment of wrong combinations of field losing equipment and interpretation method and deficiency of experience. Round robin test was performed and testing equipment and procedure were compared. Adequate downhole seismic testing equipment was constructed based on the comparison and verification study of the round robin test. The data acquisition and software interpretation were also developed for automation and quick test in field. Finally, the effectiveness and applicability were verified through the field test by using the constructed testing system.

Objectives : Oral pain without identifiable oral mucosa lesion is probably multifactorial origin, which include burning mouth syndrome (BMS), oral candidiasis and so on. The aim of this study was to analyze the characteristics of oral pain without identifiable oral mucosa lesion and to evaluate treatment outcome of those patients. Materials and Methods : We reviewed 50 patients without identifiable oral mucosa lesion who were complaint of oral pain. The patients were analyzed according tothe sites, associated symptoms, laboratory tests and fungus culture. The questionnaire included questions on their current diseases, smoking and alcoholic history, psychological factors, and symptoms. Results : The average age of patients was 60 years old. The most frequently involved site was tongue (92%), followed by palate, lower lip, oropharynx, and gingiva. 60% of the patients has psychological disorder as self reported. Culture for Candida was positive in 36% of patients and serum zinc deficiency was present in 60% of patients. Serum iron, vitamin B12, hemoglobin, folic acid deficiency were present in 6-2% of patients. Seventeen patients (65%) with BMS and twelve patients (66%) with oral candidiasis were improved after treatment. Conclusion : We recommend oral candida culture to oral pain patients without oral mucosa lesion. Zinc supplementation of zinc depletion patients may be helpful whereas other laboratory tests have no diagnostic values.

Subject : Treatment of acupuncture & moxibustion in Huangdineijing Objectives : Discover the principles and substances of acupuncture & moxibustion treatment of Huangdineijing Methods : The author reviewed the Huangdineijing: Suwen, Lingshu to gain a realistic sense of the facts and the medical book's contents that deal with the practices of acupuncture & moxibustion treatment for clinical praxis. Conclusions : 1. The acupuncture & moxibustion of Huangdineijing can be defined as follows. A treatment for correcting of meridian's drift by proper selection of surgical site, using suitable implementation and appropriate manipulation skill from a correct judgement of meridian's flowing through sensing the pulse for diagnosis when the meridian's flowing which come and go constantly driven by the tidal order of defensive Qi tactually appeared hard or soft caused by diseases, thus bring out the soft & gradual 50 laps circulation of nutrient Qi moderately driven by defensive Qi. 2. Today's acupuncture & moxibustion treatments greatly differ from those of Huangdineijing in that we do not know the substance of that treatment which is correcting of meridian's drift and do not obligatorily carry out feeling of the pulse for diagnosis which is a measure & judgement of meridian's flowing against a preliminary treatment in parallel with treatment so reduce use and power of that treatment. 3. I could form a list of general principle from the substances of acupuncture & moxibustion of Huangdineijing like as the flowing or fate of meridian Qi(tidally going in order of defensive Qi and nutrient Qi), deficiency or excess of Meridian flowing, comparing diagnosis before and after treatment, bring out the soft & gradual Qi. That was imposing "the concept of time" on recognition and treatment to human body.

Purpose : This Study was conducted to evaluate clinical characteristic of children with recurrent abdominal pain (RAP) and to be classified by its six subtype in the Oriental Pediatric Text Book and to find out relationship of western classification. Methods : Patients who visited Dong-Eui Oriental Medical hospital from August, 2001 to October, 2002 due to RAP were included. According to questionnaire and history taking, RAP was classified by its six subtype based on Oriental medical theory. Results : 1. Patients with RAP were more internalized, have a close relation with their parents, and have strong desires of success, but social intercourse is low. 2. 76% of Patients have a less desire to eat and 67% of Patients have a diarrhea or constipation. 3. According to questionnaire, first abdominal pain was their $3{\sim}5$ ages most, cause of occurrence was more 'eating cold foods' most, time of AP (abdominal pain) was $1{\sim}2$ hours after eating and no characteristic most, site of AP was the umbilicus most, shape of AP was impotent pain most, cause of reduce pain was abdominal massage and defection most. 4. frequency of RAP's type, AP caused by diet(食積腹痛) is 45.5%, AP caused by cold(寒腹痛) is 29.1%, AP caused by cold in internal organs of deficiency(臟腑虛冷腹痛) is 12.7%, stagnation of qi and stasis of blood(氣滯血瘀腹痛) is 10.9%, AP caused by internal diet and external cold(內食外寒腹痛) is 1.8%. There is no AP caused by parasites(蟲腹痛). 5. During clinical classifications of RAP, cause of occurrence was most important cause of reduce pian, defection practice was helpful for diagnosis, but shape of AP, site of AP was not helpful. 6. With relationship of Oriental classification and western classification, AP caused by diet is similar to dysmotilitylike dyspepsia and irriTable bowel syndrome. AP caused by cold is similar to irriTable bowel syndrome. AP caused by cold in internal organs of deficiency is similar to unspecified dyspepsia. stagnation of qi and stasis of blood and AP caused by internal diet and external cold is not like to western classification. Conclusion : RAP in Childhood is most occurred by food and cold. there is few AP caused by stagnation of qi and stasis of blood and internal diet and external cold. So the study on subclassification and clinical Manifestations of RAP in Childhood is more performed.

Innate immunity is the ability to differentiate infectious agents from self. The innate immune system is comprised of a complicated network of recognition and effector molecules that act together to protect the host in the early stage of an infectious challenge. Mannose-binding lectin (MBL or mannose-binding protein, MBP) belongs to the family of $Ca^{2+}$-dependent lectins (C-type lectin with a collagen-like domain), which are considered an important component of innate immunity. While it is associated with increased risk and severity of infections and autoimmunity, the most frequent immuno-deficiency syndrome was reported to be low MBL level in blood. Deficiency of human MBL is caused by mutations in the coding region of the MBL gene. Rat homologue gene of human MBL gene was used to study functions of wild type and mutant MBL proteins. Although extensive studies have yielded the structural information of MBL, the functions of MBL, especially mutant MBL, still require investigation. We previously reported the cloning of rat wild-type MBL gene and the production of a truncated form of MBL protein and its antibody. Here, we present the cloning of mutant MBL cDNA in collagen-like domain (R40C, G42D, and G45E) using site-directed mutagenesis and differential behaviors of wild type and mutant MBL in cells. The major difference between wild type and mutant MBL was that while wild type MBL was secreted, mutant MBL was inhibited for secretion, retained in endoplasmic reticulum, and still functioned as a lectin.

The patternless potteries excavated from the Baekseokdong Gojaemigol site in Cheonan, was subdivided into talc and non-talc (including amphibole) type pottery. The potteries showed black, reddish brown and yellowish brown colors, but represent to difference with occurrences and internal texture of raw materials and temper minerals. The all potteries and paleosoils are commonly high content of temper minerals with poorly sorting and roundness of particles, and the paleosoils composed mainly of quartz, plagioclase, mica, chlorite and kaolinite. Between the talc and non-talc type potteries are very similar with magnetic susceptibility, absorption ratio and specific gravity. Geochemical behaviors of major, minor, compatible and incompatible elements in talc pottery are very similar with amphibole, non-talc pottery and paleosoils, and well correspondence with enrichment and deficiency patterns of each element, and the talc and amphibole potteries are highly enriched patterns of MgO concentration. In paleosoils of Gojaemigol site, talc and amphibole are not detected, therefore, making the pottery of the site estimate the possible to artificial additions of the temper minerals of talc and amphibole used interbedded talc layer within gneiss complex near the Baekseokdong area. Based on the phase relations, differential thermal and thermal gravimetric analyses, the potteries could be classified into two groups by firing temperature. The one group of talc temper pottery fired from 800 to $870^{\circ}C$ and the other group of amphibole and non-talc temper pottery revealed of 900 to $950^{\circ}C$.

Purpose: Osseointegration of implants in patients with pneumatized maxillary sinuses is difficult to achieve due to the deficiency of available bone in the posterior maxilla after loss of teeth. Maxillary sinus elevation is a method to overcome this problem. In this study, we evaluated the implant survival rate and the relationship between implant survival in patients with sinus elevation by the lateral approach. Materials and Methods: A total of 48 patients were consecutively treated with sinus elevation by the lateral approach between February 2003 & August 2006 at the dental hospital of Chonbuk National university. A total of 113 implants were placed. The mean healing period was 7.1 months and implants were placed after a mean period of 5.6 months. The mean observation period was 21.8 months. Results: Out of the 113 implants placed, fifteen failed, resulting in a survival rate of 86.7%, 18 cases of sinus membrane perforation were observed out of 65 sinuses treated. 33 implants were placed in a perforated site and 10 failed, representing a 60.7% implant survival. 80 implants were placed in a nonperforated site and 5 failed, representing a 92.6% implant survival. Conclusions: Implant placement with sinus elevation is an acceptable treatment for short term results. Sinus membrane perforation and postoperative complications, however, may have an effect on implant failure.

The tunnel measurement data such as deficiency quantity, outbreak quantity, inner displacement and crown settlement are very important elements in tunnel sites under construction and obtained mostly by displacement gauge and total station. However, it is difficult and dangerous to install targets or measurement equipments on the points in tunnel construction site and also we need several persons to work in the tunnel. Non-prism total station with remote control system which is developed recently has various efficient functions for tunnel measurement. Therefore, for efficient tunnel measurement, this study suggested one person surveying system which consisted of non-prism total station and notebook PC to control total station remotely, and we evaluated the suggested tunnel measurement system. In this study, the tunnel site under construction was chosen as the test field and tunnel surveying was done by existing surveying method and suggested method separately. As result of the test, we analyzed processing time and accuracy to demonstrate the superiority of suggested one person non-prism surveying system.

Background: Cryptotia correction by V-Y advancement of a temporal triangular flap was introduced in 2005. However, despite the several advantages of V-Y advancement, visible scars at the donor site are problematic. As a result, a Z-plasty technique was considered for skin deficiency in mild cases. Therefore, we introduce a new surgical scheme for cryptotia correction based on considerations of techniques and complications that arose in our clinic. Methods: Between 2000 and 2013, 26 patients (35 cases) of cryptotia were treated. Seventeen patients had unilateral cryptotia and nine had bilateral cryptotia. Two corrective methods were used, Z-plasty or V-Y advancement, based on the severity. In mild cases, Z-plasty was used for correction and in severe cases, V-Y flap advancement was used for more skin supplement. Results: Follow-up periods ranged from 6 months to 1.5 years. The results obtained were relatively favorable. Nine cases of mild deformity were corrected by Z-plasty, and the other 26 cases with mild or severe deformities were corrected by V-Y advancement. In Z-plasty cases, there was one hypertrophic scar and in V-Y advancement cases, seven resulted in visible scarring and three in skin sloughing. Conclusion: The main advantage of Z-plasty is a lower likelihood of visible scarring at the donor site. In mild cases, Z-plasty may be a good alternative, but in severe cases, V-Y advancement is probably the best option for more skin supplement.
