  • $^{131}I$-metaiodobenzylguanidine(MIBG) has been used for the diagnosis and treatment of neural crest tumors. We report our experience with this agent in 8 patients[1 multiple endocrine neoplasia(MEN) type IIb; 2 malignant pheochromocytoma; 5 medullary thyroid carcinoma(MTC)]. The therapeutic procedure consisted of 30-200 mCi of $^{131}I-MIBG$ administered by slow I.V. infusion, given at 3-6 months intervals. Commutative activity ranged from 150 mCi to 410 mCi, in 1 to 4 courses. $^{131}I-MIBG$ therapy resulted in significant disease free interval in 1 malignant pheochromocytoma(no measurable lesion) after surgery; complete hormonal and tumoral response in 2 MTC(1 MEN IIb): stable disease in 1 recurred pheochromocytoma(MEN IIb): stable disease but symptomatic improvement in 1 MTC, progressive disease in 1 malignant pheochromocytoma and 2 MTC. The patients who showed progression appeared to have large inoperable tumors or postoperative remnant tumors.

  • Objective: The objective of this study was to evaluate increasing doses of a novel microbial phytase (Cibenza Phytaverse, Novus International, St. Charles, MO, USA) on standardized total tract digestibility (STTD) of P in canola meal (CM), corn, corn-derived distiller's dried grains with solubles (DDGS), rice bran (RB), sorghum, soybean meal (SBM), sunflower meal (SFM), and wheat. Methods: Two cohorts of 36 pigs each (initial body weight = $78.5{\pm}3.7kg$) were randomly assigned to 2 rooms, each housing 36 pigs, and then allotted to 6 diets with 6 replicates per diet in a randomized complete block design. Test ingredient was the only dietary source of P and diets contained 6 concentrations of phytase (0, 125, 250, 500, 1,000, or 2,000 phytase units [FTU]/kg) with 0.4% of $TiO_2$ as a digestibility marker. Feeding schedule for each ingredient was 5 d acclimation, 5 d fecal collection, and 4 d washout. The STTD of P increased (linear or exponential $p{\leq}0.001$) with the inclusion of phytase for all ingredients. Results: Basal STTD of P was 37.6% for CM, 37.6% for corn, 68.6% for DDGS, 10.3% for RB, 41.2% for sorghum, 36.7% for SBM, 26.2% for SFM, and 55.1% for wheat. The efficiency of this novel phytase to hydrolyze phytate is best described with a broken-line model for corn, an exponential model for CM, RB, SBM, SFM, and wheat, and a linear model for DDGS and sorghum. Based on best-fit model the phytase dose (FTU/kg) needed for highest STTD of P (%), respectively, was 735 for 64.3% in CM, 550 for 69.4% in corn, 160 for 55.5% in SBM, 1,219 for 57.8% in SFM, and 881 for 64.0% in wheat, whereas a maximum response was not obtained for sorghum, DDGS and RB within the evaluated phytase range of 0 to 2,000 FTU/kg. These differences in the phytase concentration needed to maximize the STTD of P clearly indicate that the enzyme does not have the same hydrolysis efficiency among the evaluated ingredients. Conclusion: Variations in enzyme efficacy to release P from phytate in various feedstuffs need to be taken into consideration when determining the matrix value for phytase in a mixed diet, which likely depends on the type and inclusion concentration of ingredients used in mixed diets for pigs. The use of a fixed P matrix value across different diet types for a given phytase concentration is discouraged as it may result in inaccurate diet formulation.

  • Objective: Significant portion of premature ovarian failure patients ovulate intermittently and even can achieve pregnancy. The clinical features and reproductive potentials of Korean women with premature ovarian failure have never been elucidated. The purpose of this study is to assess ovarian follicular growth and ovulatory potential. Methods: Complete medical records of fifteen women with idiopathic premature ovarian failure were reviewed retrospectively. Subjects with more than 6 ultrasonographic scans and 36 months of follow-up period were included. Once the ovarian follicle was found by ultrasonography, the follicular growth was serially monitored. The result of ovulation induction of 6 cycles in 4 patients were also evaluated. Rate of positive ovarian follicle by ultrasound, rate of natural follicular growth and response of ovulation induction were assessed. Results: Among the 15 patients, 6 women (40%) had ovarian follicle in random ultrasonography. But the chance of positive follicle per ultrasonography scan was 7% (8 out of 115 scans). One out of 6 women eventually ovulated during the follow-up scan. In remaining 5 subjects, size of follicles remained unchanged. None of 6 ovulation induction cycles resulted successful ovulation. Conclusion: Incidence of positive ovarian follicle in Korean premature ovarian failure patients is lower than that of Western counterpart. This result, however, could not be directly compared because of the differences of study design. The ovulation rate by medical ovulation induction in this group is 0%, which is worse than the reported success rate of Western studies.

  • Purpose : This study was to evaluate survival, failure patterns, and prognostic factors of stage I squamous cell carcinoma of the glottic larynx after curative radiation therapy. Materials and Methods : A retrospective analysis was done for 57 patients with glottic cancer who were treated with curative radiation therapy from June 1985 to November 1992. There were 55 male and two female patients. Patients' age ranged from 17 to 71 years(median 39 years). Radiation therapy was delivered five times a week, 2 Gy daily, total 66 Gy using 6 MV X-ray. Results : Complete response(CR) was noted in 51 out of 57 patients (89.5%) and persistent disease (PER) in six out of 57 patients(10.5%). The disease-free survival rates at 3 and 5 years were 72.9% and 63.8%, respectively. Seven failures were observed among 51 CR patients during follow-up. Salvage total laryngectomy for six recurred patients and partial laryngectomy for one recurred patient were done with successful results, i.e., all of them were actually salvaged. Among six PER patients, salvage total laryngectomy for two patients and partial laryngectomy for two patients were done and two patients refused operation. Following salvage surgery for the four PER patients, three were salvaged and one failed locoregionally. Among the 13 failures 10(76.9%) were salvaged with surgery. The ultimate local control rate at 5 years was 92.3% and overall 47 out of 57 (82.5%) patients were able to preserve their larynx. The 5-year disease-free survival rates were 85.5% for posterior lesions, and 61.6% for anterior lesions(P<0.05). Cord mobility, involvement of anterior commissure, field size, and T stage did not impact on disease-free survival. Conclusion : Considering the high percentage of voice preservation with initial radiotherapy, radiotherapy should be the first choice in the treatment of stage 1 glottic carcinoma.

  • Because a procedure is complicated and various related parties participate in the redevelopment and reconstruction project, it can be extended to diverse disputes when the relation with the related parties is smoothly adjusted. In particular, when the dispute occurs in a phase of occupancy after the complete construction, the regional residents-centric association must give up many rights of invisible parts caused by the construction company's profit maximization because they are short of professionalism about the business. Accordingly, this study is aimed at providing the construction project manager's dispute and claim process for responding to the dispute or claim reasonably and for obtaining the client's (association) rights for the reconstruction project, and at developing the checklist for obtaining the necessary documents by each phase, when the dispute or claim is made by the association against the construction company after the completion of construction. Through this study, the association can obtain the related documents in advance and can implement the reasonable response data when the dispute or claim occurs due to it. Also, it will enable the construction manager to analyze the project costs reasonably and will reduce the estimated wastes. That is, the work efficiency is expected to be improved.

  • This study investigates the response of a typhoon model to the change of the sea surface temperature (SST) throughout the model integration. The SST change is parameterized as a formulae of which the magnitude is given as a function of not only the intensity and the size but the moving speed of tropical cyclone. The formulae is constructed by referring to many previous observational and numerical studies on the SST cooling with the passage of tropical cyclones. Since the parameterized cooling formulae is based on the mathematical expression, the resemblance between the prescribed SST cooling and the observed one during the period of the numerical experiment is not complete nor satisfactory. The agreements between the prescribed and the observed SST even over the swath of the typhoon passage differ from case to case. Numerical experiments are undertaken with and without prescribing the SST cooling. The results with the SST cooling do not show clear evidence in improving the track prediction compared to those of the without-experiments. SST cooling in the model shows its swath along the incomplete simulated track so that the magnitude and the distribution of the sea surface cooling does not resemble completely with the observed one. However, we have observed a little improvement in the intensity prediction in terms of the central pressure of the tropical cyclone in some cases. In case where the model without the SST treatment is not able to yield a correct prediction of the filling of the tropical cyclone especially in the decaying stage, the pulling effect given by the SST cooling alleviates the over-deepening of the model so that the central pressure approaches toward the observed value. However, the opposite case when the SST treatment makes the prediction worse may also be possible. In general when the sea surface temperature is reduced, the amount of the sensible and the latent heat from the ocean surface become also reduced, which results in the weakening of the storms comparing to the constant SST case. It turns out to be the case also in our experiments. The weakening is realized in the central pressure, maximum wind, horizontal temperature gradient, etc.

  • The objectives of this study were to compare growth of Pllioblastus pygmaed and soil characteristics as affected by difference of soil thickness and mixture ratio in shallow-extensive green roof module system, and to identify the level of soil thickness and mixture as suitable growing condition to achieve the desired plants in green roof. Different soil thickness levels were achieved under 15cm and 25cm of shallow-extensive green roof module system that was made by woody materials for $500{\times}500{\times}300mm$. Soil mixture ratio were three types for perlit: peatmoss: leafmold=6:2:2(v/v/v, $P_6P_2L_2$), perlit: peatmoss: leafmold=5:3:2(v/v/v, $P_5P_3L_2$) and perlit: peatmoss: leafmold=4:4:2(v/v/v, $P_4P_4L_2$). On June 2006, Pllioblastus pygmaed were planted directly in a green roof module system in rows. All treatment were arranged in a randomized complete block design with three replication. The results are summarized below. In term of soil characteristics, Soil acidity and electric conductivity was measured in pH 6.0~6.6 and 0.12dS/m~0.19dS/m, respectively. Organic matter and exchangeable cations desorption fell in the order: $P_4P_4L_2$ > $P_5P_3L_2$ > $P_6P_2L_2$. $P_6P_2L_2$ had higher levels of the total solid phase and liquid phase, and $P_4P_4L_2$ had gas phase for three phases of soil in the 15cm and 25cm soil thickness. Although Pllioblastus pygmaed was possibled soil thickness 15cm, there was a trend towards increased soil thickness with increased leaf length, number of leaves and chlorophyll contents in 25cm. The growth response of Pllioblastus pygmaed had fine and sustain condition in order to $P_6P_2L_2$ = $P_5P_3L_2$ > $P_4P_4L_2$. However, The results of this study suggested that plants grown under $P_4P_4L_2$ appear a higher density ground covering than plants grown under $P_6P_2L_2$. Collectively, our data emphasize that soil thickness for growth of Pllioblastus pygmaed were greater than soil mixture ratio in shallow-extensive green roof module system.

  • Objectives: The aim of this study was to find out the attitude of Korean women towards IVF surrogacy which is not yet regulated by the law. Methods: We evaluated with a questionnaire, in how far IVF surrogacy was accepted in different groups of Korean women. Total 300 questionnaires were sent out to women who visited our infertility clinic, and to the nurses and office workers of our hospital. Among them, 246 questionnaires were returned, and 211 of them (85.7%) were complete and analyzed. The responders were 58 unmarried women and 153 married women including 60 infertile patients. Results: Only 17 (8.1%) women believed that IVF surrogacy was an acceptable treatment for infertile women without uterus (eg. MRKH or hysterectomized patients), and 125 (59.2%) women chose the adoption. There were no significant differences in response amongst different age group, marital status, or in relation to income level or educational level, or infertility status. A significantly higher level of acceptance was noted only in religious groups, especially in Christians. Most of responders (66.5%) chose unrelated and unknown women as a desirable host, and 28.4% of responders chose the sister or sister-in-law. Conclusions: Overall the different groups were critical towards IVF Surrogacy in Korea, irrespective of the infertile patient group. Despite the established clinical ability to have her own genetic child in women without uterus, this survey reveals that only minority supports the IVF surrogacy. So we need the survey with large, randomized population and then make a regulation about the IVF surrogacy in law.

  • This study searched the philosophical and medical thought of mutual understanding and human body. Mutual understanding is a fundamental problem in all branches of oriental studies. In other words, mutual understanding becomes the existential foundation of heaven-earth-human(三才). So human beings, heaven and the earth can't exist if there is no mutual understanding. It comes out the problem of self-consciousness in philosophy, and qi movement pattern like upward, downward, inward and outward movement in traditional korean medicine. Human beings have mutual understandings with heaven and the earth from a macroscopic standpoint, on the other side the human body from a microscopic standpoint. Qi movement is the mutual understanding and response of qi in human body, so with which the physiological functions and pathologic changes of viscera and bowels comes out. Therefore we want to present how to complete qi movement between viscera-bowels and organs to examine mutual understandings in human body closely. The results was summarized as follows; First, upbearing the clear yang and down bearing the turbid yin of spleen-stomach is main pivot of upward and downward of qi movement, and it is true form of mutual understandings between viscera and bowels, so upward, downward, inward and outward movement of whole viscera and bowels can be controlled by spleen-stomach. Second, by restraining relationships between downward heart fire and upward kidney water, heart fire and kidney water have close communications physiologically and pathologically as upper-lower, yin-yang and water-fire. Third, by restraining relationships between upbearing and effusion of liver and purification and down-sending of lung, liver and lung are outer circles of upward and downward movement, so they have antagonistic functions. Firth, by the relationships between upbearing the clear and down bearing the turbid of spleen-stomach and free coursing of liver, free coursing of liver-gallbladder is the essential requirement that it certify transportation and transformation of spleen-earth, so the disease of liver-gallbladder induce spleen-stomach disease pattern to affect its function of transportation and transformation. Fifth, by spleen and kidney, spleen yang is based on kidney yang, so the weakness of kidney yang can affect the function of transportation and transformation of spleen-stomach as it can't warm spleen earth. Sixth, by homogeny of liver-kidney, essence and blood of liver-kidney and ministerial fire of liver-kidney have mutal generation and limitation physiologically and they mutually are affected in pathologically.

  • Introduction: To evaluate whether modified MUPIT applicator can effectively eradicate recurrent tumor in uterine cervix cancer and reduce rectal complication after complete radiation treatment. Methods and Materials: Modified MUPIT applicator basically consists of an acrylic cylinder with flexible brain applicator , an acrylic template with a predrilled array of holes that serve as guides for interstitial needles and interstitial needles. CT scan was performed to determine tumor volume and the position of interstitial needles. Modified MUPIT applicator was applied to patient in operation room and the accuracy for position of interstitial needles in tumor volume was confirmed by CTscan. Brachytherapy was delivered using modified MUPIT applicator and RALS (192-Ir HDR) after calculated computer planning by orthogonal film. The daily dose was 600cGy and the total dose was delivered 3000cGy in tumor volume by BID. Rectal dose was measured by TLD at 5 points so that evaluated the risk of rectal complication. Result: The application of modified MUPIT applicator improved dramatically dose distributions in tumor volume and follow-up of 3 month for this patient was clinically partial response without normal tissue complication, Rectal dose was measured 34.1cGy, 57.1cGy, 103.8cGy, 162.7cGy, 165.7cGy at each points, especially the rectal dose including previous EBRT and ICR was 34.1cGy, 57.1cGy Conclusion: Patients with locally recurrent tumor in uterine cervix cancer treated with modified MIUPIT applicator can expect reasonable rates of local control. The advantages of the system are the fixed geometry Provided by the template and cylinders, and improved dose distributions in irregular tumor volume without rectal complication
