  • Objectives : In the present study, the author intended to investigate whether two oriental medical prescriptions named Socheongryongtang-ga-seoggo (SCTS) and Prescription D (P-D) significantly affect mucin release from cultured hamster tracheal surface epithelial (HTSE) cells. Materials and Methods : Confluent HTSE cells were metabolically radiolabeled with 3H-glucosamine for 24 hrs and chased for 30 min in the presence of SCTS or P-D to assess the effect of each agent on 3H-mucin release. Possible cytotoxicities of each agent were assessed by measuring lactate dehydrogenase (LDH) release. Also, the effects of SCTS and P-D on contractility of isolated tracheal smooth muscle were investigated. Results : SCTS did not affect mucin release from cultured HTSE cells, without cytotoxicity. However, P-D significantly increased mucin release from cultured HTSE cells. with significant cytotoxicity. SCTS inhibited Ach-induced contraction of isolated tracheal smooth muscle. P-D also inhibited Ach-induced contraction of isolated tracheal smooth muscle. Conclusions : The author suggests that the effects of SCTS and P-D with their components should be further investigated and it is valuable to find, from oriental medical prescriptions, novel agents which might regulate mucin secretion from airway goblet cells.

  • Objectives The purpose of this study was to find out whether there were differences of urticaria's disease aspect between patients classified into Sasang Constitution Types(SCTs) and whether those differences could be associated with Ordinary symptoms. Methods Medical records and questionnaires about 117 patients who visited one Korean medicine hospital due to urticaria were collated and statistically analyzed. Results 1) Ages 20 to 30, women, Soeumin(SE) and patients in conditions of chronic urticaria over 6 weeks were the majority among 117 patients in this study. Food and stress were most chosen as the main cause of urticaria. 2) Soyangin(SY) showed more severe symptoms of urticaria than other SCTs. In particular, the severity of pruritus, distribution of lesions and vulnerability to stress was statistically significant compared to other SCTs(p<0.05). SE expressed urticaria's symptoms at the medium-level of SY's and Taeeumin(TE)'s. TE exhibited relatively weak symptoms but TE only had slightly higher number of patients with angioedema compared to other SCTs. Taeyangin(TY) was only one case so more researches are needed. 3) In dispositional symptoms, SY had low quality of sleep and defecation. SE could not digest oily food well, felt dizzy and cold well, and had cold hands and feet. TE could eat and sweat much and tended to snore well. Conclusions In this study, urticaria had common cause of both stress and food in all SCTs but onset and severity of symptoms were different between SCTs. It could interpreted that these differences between SCTs were associated with ordinary symptoms native to each SCT.

  • Sasang constitutional medicine (SCM) is one of the best traditional therapeutic approaches used in Korea. SCM prioritizes personalized treatment that considers the unique constitution of an individual and encompasses their physical characteristics, personality traits, and susceptibility to specific diseases. Facial features are essential for diagnosing Sasang constitutional types (SCTs). This study aimed to develop a real-time artificial intelligence-based model for diagnosing SCTs using facial images, building an SCTs prediction model based on a machine learning method. Facial features from all images were extracted to develop this model using feature engineering and machine learning techniques. The fusion of these features was used to train the AI model. We used four machine learning algorithms, namely, random forest (RF), multilayer perceptron (MLP), gradient boosting machine (GBM), and extreme gradient boosting (XGB), to investigate SCTs. The GBM outperformed all the other models. The highest accuracy achieved in the experiment was 81%, indicating the robustness of the proposed model and suitability for real-time applications.

  • Nowadays, people perform their tasks anywhere anytime using their mobile devices. For this reason, data synchronization (DS) between mobile devices and a central server has become one of the most essential technologies in mobile environments. Currently, several mobile DS protocols are proposed and used. However, the existing DS protocols cannot guarantee interoperability between them. To solve the problem, an embedded DS gateway has been developed in our previous study. The gateway runs on a Windows Mobile-based emulator. It converts data on a mobile device into common data specified by OMA DS standard protocol and vice versa. The embedded gateway has been built to support the OMA DS standard protocol. In order to verify that the embedded gateway conforms to the OMA DS standard protocol, two kinds of OMA conformance tests have to be conducted - interoperability test with an OMA DS-based server and conformance test with SCTS (SyncML Conformance Test Suit). In this paper, some parts of the gateway previously built are modified and the modified gateway is installed on a Windows Mobile-based smart phone. And the interoperability test and the conformance test with the SCTS are conducted. The results of the tests show that the embedded DS gateway operates properly on the Windows Mobile-based smart phone and that the gateway passes the tests, verifying its conformity to the OMA DS standard protocol. In addition, DS performance tests show that DS delay times between a real smart phone and a DS server increase gently as the number of DS data increases. In other words, the embedded DS gateway built in this paper can be used for a real smart phone at a reasonable performance cost.

  • 본 논문에서는 모바일 통신 환경을 위한 자료동기화 서버를 구축하였으며, 구축된 서버의 적합성 및 성능 검증결과를 제시한다. 본 논문에서 구축한 자료동기화 서버는 클라이언트(모바일 단말기)가 최신의 자료를 유지할 수 있게 도와주며, 클라이언트와 서버 간 자료의 일치성을 보장하도록 한다. 또한 다양한 자료동기화 타입을 제공하며, 자료의 변경 및 충돌을 탐지하고 충돌 발생 시 이를 해결하기 위한 정책을 제공한다. 게다가, OMA(Open Mobile Alliance) DS(Data Synchronization) 프로토콜을 준수함으로써, 상호 호환성을 보장하도록 설계 구현되었다. 뿐만 아니라, 기존의 자료동기화 서버들이 사용하는 레코드 단위 전송방식의 단점을 보완하기 위해 필드 단위 전송 방식도 지원하도록 구현되었다. 구축된 자료동기화 서버의 기능 및 성능 적합성을 검증하기 위해 OMA에서 제공하는 적합성 검증 도구인 SCTS(SyncML Conformance Test Suit)와의 동기화를 수행하였으며, 다양한 상황에서 의 성능을 평가하였다. 검증 결과, SCTS 항목 중 대용량 오브젝트 기능을 제외한 모든 검증 항목을 만족함을 알 수 있었다. 대용량의 오브젝트를 분할하여 전송하는 기능은, 개인정보 동기화 목적의 본 연구에는 필요치 않아 구현하지 않았으며, 향후 구현할 예정이다. 서버의 성능을 평가하기 위한 동기화 소요시간 측정 결과, 본 논문의 자료동기화 서버는 동기화 자료 및 클라이언트 수의 증가에 따른 동기화 소요시간의 증가가 완만함을 확인할 수 있었으며, 확장성이 있다고 판단하였다. 또한, 제안된 서버와 동일한 프로토콜을 사용하는 SCTS 서버, Synthesis와 성능을 비교 한 결과, SCTS 서버에 비해 제안된 서버를 사용하였을 때가 동기화에 요구되는 시간이 더 짧음을 알 수 있었다. Synthesis 서버와 비교해보면, 제안된 서버가 더 많은 동기화 소요시간을 요구하지만, 동기화 할 자료의 수가 많고 동기화 대상 자료(레코드)의 일부 필드만 변경된 상황에서는 제안된 서버가 더 우수함을 알 수 있었다. 즉, 제안된 서버는 기존의 자료동기화 서버들과 비교해 동일하거나 추가된 기능을 제공하면서도, 동기화 자료의 수가 증가할수록 더 우수한 성능을 보여줌을 뜻한다. OMA DS를 준수하는 자료동기화 서버를 직접 구축해봄으로써, 향후 모바일 DS 기능을 개선하기 위한 다양한 연구의 기초 프레임이 될 것이라고 기대한다.

  • Sertoli cell tumor (SCT) of the testicle arises from the supporting cells within the seminiferous tubules. SCT is common in dogs, especially in cryptorchid testicles, but also has been reported in the stallion, ram, cat, and bull. Sertoli cell tumor sample was collected from 7-years male german shepherd. In this study, SCT arose from one testicle. Sample size is approximately 1.7 cm in diameter and it has a round form. In the microscopic, cells within the tumor variably resemble Sertoli cells (SCs) that normally populate the seminiferous tubules and interstitial area. There is abundant stroma of dense, mature fibrous connective tissue in SCT. In the immunohistochemical staining, cytokeratin AE1/AE3 was not expressed in the control and SCT. S-100 protein was expressed by SCs, germ cells and fibrous connective tissue of SCT. Melan A was expressed by leydig cells (LCs) of SCT. A study by using S-100 and melan A in canine SCT was almost never carried out. S-100 and melans A is considered to suggest for diagnosis and pathogenesis of canine SCTs. Inhibin-alpha and Vimentin were well known as the marekers of SCTs. Also, they were expressed by Sertoli cells and LSs of SCT in this study.

  • We have cloned and characterized a lipocalin from the bumblebee Bombus ignitus (Bi-lipocalin). The Bi-lipocalin gene spans 2284 bp and consists of four exons coding for 270 amino acid residues. Sequence analysis revealed that Bi-lipocalin possesses three structurally conserved regions (SCTs) that characterize lipocalins. Recombinant Bi-lipocalin, expressed as a 37 kDa protein in baculovirus-infected insect cells, was N-glycosylated, indicating that the carbohydrate moieties are necessary for secretion. Tissue distribution analysis revealed ubiquitous expression of Bi-lipocalin in all tissues examined. Bi-lipocalin transcripts were upregulated by stress, such as wounding, $H_2O_2$ exposure, and external temperature shock. These results indicate that Bi-lipocalin is a stress-inducible protein that acts on wounding, $H_2O_2$ overexposure and temperature stimulation.

  • Current internet has evolved from the sharing and efficiency aspects of information, it is still vulnerable to the fact that the Internet is not secure in terms of security and is not safe to secure of security mechanism. Repeating patches on continuous hacking are continuously demanding additional resources for network or system equipment, and consequently the costs continue to increase. Businesses and individuals alike are speeding up the damage caused by crime like of ransomware, not jusy simple attacks, and businesses and individuals need to respond to cyber security. In addition, the ongoing introduce of security device, and separate of networks for secure transmission of contents in the existing TCP/IP system, but it is still lacking in security. To complement the security implications of this existing TCP/IP Internet Protocol, we intend to propose a Secure Contents Transport System (SCTS) on the network using the CCN concept.

  • Some canine typical Sertoli cell tumors (SCT) induce signs of hyperestrinism. However, whether variant lipid-rich SCTs have signs of hyperestrinism remains largely unknown. In the present study, an 11-year-old male Pekingese dog showed significantly elevated serum estrogen and characteristic signs of hyperestrinism such as gynecomastia and alopecia. Cytological, radiological and ultrasound examinations found testicular mass, prostatitis with squamous metaplasia, and cystitis. Pathologically, the tumor lesions consisted mainly of lipid-rich tumor cells with signet-ring appearance, which were immunohistochemically positive for vimentin and anti-$M{\ddot{u}}llerian$ hormone. Based on the findings, a diagnosis of lipid-rich Sertoli cell tumor was established. In conclusion, a canine lipid-rich SCT induced signs of hyperestrinism and caused prostatitis via squamous metaplasia due to its excessive secretion of estrogen.
