The $(Sr_{0.85}Ca_{0.15})TiO_3$(SCT) thin films were deposited on Pt-coated electrode (Pt/TiN/$SiO_2$/Si) using RF sputtering method according to the deposition condition. The optimum conditions of RF power and Ar/$O_2$ ratio were 140[W] and 80/20, respectively. Deposition rate of SCT thin films was about 18.75[${\AA}/min$] at the optimum condition. The capacitance characteristics had a stable value within ${\pm}4[%]$. The drastic decrease of dielectric constant and increase of dielectric loss in SCT thin films were observed above 200[kHz].

The $(Sr_{1-x}Ca_x)TiO_3$(SCT) thin films are deposited on Pt-coated electrode (Pt/TiN/$SiO_2$/Si) using RF sputtering method with substitutional contents of Ca. The optimum conditions of RF power and $Ar/O_2$ ratio were 140[W] and 80/20, respectively. Deposition rate of SCT thin film was about 18.75$[{\AA}/min]$. The dielectric constant was increased with increasing the substitutional contents of Ca, while it was decreased if the substitutional contents of Ca exceeded over 15[mol%]. All SCT thin films used in this study show the phenomena of dielectric relaxation with the increase of frequency, and the relaxation frequency is observed above 200[kHz].

A 8-year-old male Golden Retriever dog with bilateral cryptorchidism presented for evaluation of symmetric alopecia and gynecomastia. Abdominal radiography and computed tomography revealed bilateral enlargement of the testicles in the abdominal cavity. The concentrations of estradiol and testosterone in the blood were evaluated, and the results revealed a low testosterone/estradiol ratio despite a normal concentration of estradiol. For correction, cryptorchid testicles were surgically removed. Grossly, the bilateral retroperitoneal cryptorchid testicles were enlarged, firm, and spherical. On histopathologic examination, the right abdominal cryptorchid testicle was diagnosed as a Sertoli cell tumor (SCT)-Seminoma (SEM) combination. The contralateral testicle in the abdomen was diagnosed as a Sertoli cell tumor. The clinical signs of feminization were improved after surgery. To our knowledge, this is the first report of a case of simultaneous SCT on one side and SCT-SEM combination on the other side with sex hormone profiles in a dog.

Objectives : In present study, we investigated a therapeutic effect and optimum dose of Socheongryong-Tang (SCT) on LPS-induced lung inflammation rats model. Methods : Male Sprague-Dawley rats ($260{\pm}10g$) were divided into 12 groups : Group 1 included the normal rats, and Group 2-12 were administrated LPS by intranasal injection to induce experimental lung inflammation. After 1 day of LPS administration, Group 3-9 were treated with SCT ${\times}1/4$, ${\times}1/2$, ${\times}1$, ${\times}3$, ${\times}6$, ${\times}12$ or ${\times}18$, respectively. Group 10-12 (positive control) were treated with dexamethasone 1 mg/kg or acetylcystein 1.5 mg/kg or diclofenac sodium 0.4 mg/kg, respectively. After sacrifice, bronchoalveolar lavage fluid (BALF) was isolated. The levels of IL-$1{\beta}$, TNF-${\alpha}$, mucin glycoprotein 5AC (MUG5AC) were measured in BALF using enzyme-linked immunosorbent assay (ELISA). Results : LPS injected rats exhibited outstanding lung inflammation manifestations, including increased amount of total cells and neutrophil, and upregulated inflammatory cytokines level in BALF. However, the administration of SCT ${\times}1/4$, ${\times}1/2$ and ${\times}1$ decreased total cells and neutrophil, and suppressed the production of inflammatory cytokines, including $IL-1{\beta}$ and TNF-${\alpha}$, and MUG5AC in BALF. Notably, inhibitory effect of SCT ${\times}1/2$ and ${\times}1$ on the level of TNF-${\alpha}$ was markedly better than that of positive controls, dexamethasone and acetylcystein. Conclusions : Taken together, these results suggest that SCT ${\times}1/2$ and ${\times}1$ has therapeutic effects on LPS-induced lung inflammation rats model.

Newborn infants with huge and highly vascular sacrococcygeal teratoma (SCT) are frequently subjected to renal hypoperfusion secondary to high-output cardiac failure. Any underlying renal dysfunction is a significant risk factor for the development of contrast-induced nephropathy (CIN). However, reports on CIN in infants are rare. I report here a case of a premature infant born at 28 weeks and 3 days of gestation with a huge SCT who survived preoperative embolization and surgical resection but presented with persistent non-oliguric renal failure that was suggestive of CIN. During radiological intervention, a contrast medium had been administered at about 10 times the manufacturer-recommended dose for pediatric patients. Despite hemodynamic stabilization and normalization of urine output immediately following surgery, the patient's serum creatinine and cystatin-C levels did not return to baseline until 4 months after birth. No signs of reflux nephropathy were observed in follow-up imaging studies. Dosing guidelines for the use of a contrast medium in radiological interventions should be provided for infants or young patients.

Interoperability tests are required to determine whether network-based defense systems successfully share and exchange certain services, information, and data. We must examine various aspects of interoperability. The DITA (Defense Information Technical stAndard) is the basis for interoperability. However, DITA is being applied to the defense system in a state that the standard test methods and procedures are not established. And there is no test method and procedure of the DITA well applicable to military weapons systems or information systems. Therefore, in this paper, we propose a framework that includes procedures, methodologies, so as to test whether a standard is applied to the DITA in terms of Standard Conformance Test.

This paper describes the application of discrete event systems theory to the design of an automated laboratory system. Current automated laboratory systems typically consist of several interacting processes that must be carefully sequenced to avoid any possible process conflicts. Discrete Event Systems (DES) theory and Supervisory Control Theory (SCT) can be applied together as effective methods of modeling the system dynamics and designing supervisory controllers to precisely sequence the many processes that such systems might involve. Classical approaches to supervisory controller design tend to result in complex controller structures that are difficult to implement, maintain, and upgrade. In this paper, a new approach to designing supervisory controllers for automated laboratory systems is introduced. This new approach uses a modular controller structure that is easier to implement, maintain, and upgrade, and deals with "state explosion" issues in a novel and efficient way.

Cord blood (CB) has been used as an important and ethical source for hematopoietic stem cell transplantation (SCT) as well as cell therapy by manufacturing mesenchymal stem cell, induced pleuripotential stem cell or just isolating mononuclear cell from CB. Recently, the application of cell-based therapy using CB has expanded its clinical utility, particularly, by using autologous CB in children with refractory diseases. For these purposes, CB has been stored worldwide since mid-1990. In this review, I would like to briefly present the historical development of clinical uses of CB in the fields of SCT and cell therapy, particularly to review the experiences in Korea. Furthermore, I would touch the recent banking status of CB.

단일프로세서 환경에서 주기 태스크의 시간 제약 조건을 만족시키면서 비주기 태스크의 평균 서비스 시간을 최소화하는 연구가 계속 진행되어 왔으나, 최근의 시스템은 여러 개의 프로세서를 병렬처리하여 프로그램의 처리속도 향상을 꾀하는 멀티프로세서 환경으로 전환되어 가는 추세다. 따라서, 멀티프로세서 환경에서의 태스크 스케쥴링에 관한 다양한 여구가 필요하게 되었다. 일반적으로 멀티프로세서 환경에서는 주기 태스크를 스케쥴링하기 위해서 RMFF(Rate-monotonic First-Fit) 스케쥴링 알고리즘을 사용하는데, 이 알고리즘에서는 비주기 태스크의 스케쥴링을 위한 알고리즘을 추가로 요구한다. 따라서, 본 논문에서는 멀티프로세서 환경에서 주기 태스크와 비주기 태스크가 혼합되어 있을 때, 기존의 RMFF 방식에 슬랙 체크테이블(Slack Check Table;SCT)을 이용하여 비주가 태스크를 효율적으로 스케쥴링하기 위한 방법을 제안한다.

(S $r_{0.85}$/C $a_{0.15}$)Ti $O_3$(SCT) thin films at various deposition temperature and rf power were grown by rf magnetron sputtering method on optimized Pt-based electrodes (Pt/TiN/ $SiO_2$/Si). The crystallinity of the films increases with increasing deposition temperature. SCT thin film is depend on the surface morphology and crystallinity of Pt films for bottom electrode. Dielectric constant of (S $r_{0.85}$C $a_{0.15}$)Ti $O_3$ thin films deposited on Si wafer substrate are larger with the increase of deposition temperature and gain size.in size.
