Unlike benign tumors, malignant tumors are capable of metastasis, easy to relapse, poor survival, and low quality of life. In Korea, here is a tendency to treat the tumors collectively according to the General Principles of Cancer Chemotherapy(GPCC) of the Health Insurance Review & Assessment Service (HIRA). But recently, companion diagnostics(CDx) is recommended rather than unilateral medication because biomarker-based molecular diagnostics is possible to predict the drug response of patients before drug treatment. Not only domestic but also overseas Food and Drug Administratio (FDA) recommends the development of the CDx system at the stage of drug development to ensure the responsiveness and safety of medicines. In this study, I focused on the necessity of CDx development direction as well as CDx development status through literature review. Furthermore I also discussed CDx types according to the molecular diagnostic technology such as immunohistochemistry (IHC), polymerase chain reaction (PCR), in situ hybridization (ISH), and next-generation sequencing (NGS) not only in the approved CDx but also in the developing one by US FDA. And I suggested the technology issue of CDx development process such as a selection of molecular diagnostics at the time of release, a clear understanding of the CDx mechanism, and a convergence of drug with CDx development. The necessity of social insurance system also was proposed for CDx development.

In order to the excellent differentiation of syndromes, we study on the individual characteristic factor by the inspection of face colour and tongue & the auscultation and olfaction. To the subject of diagnosis special books and diagnostics textbook of korean medicine, we arrange the individual characteristic factor by the inspection of face colour and tongue & the auscultation and olfaction. The inspection on the individual characteristic factor was analyzed the face colour, inspection of tongue. The auscultation and olfaction on the individual characteristic factor was analyzed the 25 types by the five-voice (五音) in Huang Di Nei Jing (黃帝內經). As the results, the individual characteristic factor is very important item of the four methods of diagnosis and the differentiation of syndromes. And Therefore the process on four methods of diagnosis and differentiation of syndromesis is necessary to divide the signs of individual characteristic factor and the signs of disease.

Objectives Yusanghan(類傷寒) means disease which chills and fever manifest like Cold damage(傷寒) but not Cold damage. However, study on Yussanghan is insignificant. The purpose of this study is to examine the origin and development process of Yusanghan. Methods: 1. Terms and disease related with Yusanghan was collected from books covering Cold damage of all time and analyzed. 2. The transition history was researched by analyzing collected terms. 3. Total appearance frequency of all time by collected disease was researched. Results: Yusanghan was appeared in Hwalinseo(活人書), which Ju Geong(朱肱) of the Song Dynasty wrote, for the first time and the definition and type were established. For the types of those, there are four diseases such as Phlegm-Fluid Retention(痰飮), Food Accumulation(食積), Vexation of Deficiency Type(虛煩), Beriberi(脚氣). Since then, the theory about Yusanghan had developed and the number of types had also increased until the Myung Dynasty. Conclusions: In early days, External Contraction Diseases(外感病) was not included in Yusanghan, but since the late Myung Dynasty, there were a lot of doctors who included External Contraction Diseases in Yusanghan, not in Cold damage. There are Summerheat Stroke, Wind-Dampness(風濕), and Warm Disease(溫病) etc. for included External Contraction Diseases. Because of this, the number of types of Yusanhan had significantly increased.

This study suggests a generalized availability and safety evaluation model to evaluate the influences to the system's fault tolerant capabilities depending on automatic fault detection function such as the automatic periodic testings. The conventional evaluation model of automatic fault detection function deals only with the self diagnostics, and supposes that the fault detection coverage of self diagnostics is always constant. But all of the fault detection methods could be degraded. For example, the periodic surveillance test has the potential human errors or test equipment errors, the self diagnostics has the potential degradation of built-in logics, and the automatic periodic testing has the potential degradation of automatic test facilities. The suggested evaluation models have incorporated the loss or erroneous behaviors of the automatic fault detection methods. The availability and the safety of each module of the safety grade platform have been evaluated as they were applied the automatic periodic test methodology and the fault tolerant evaluation models. The availability and safety of the safety grade platform were improved when applied the automatic periodic testing. Especially the fault tolerant capability of the processor module with a weak self-diagnostics and the process parameter input modules were dramatically improved compared to the conventional cases. In addition, as a result of the safety evaluation of the digital reactor protection system, the system safety of the digital parts was improved about 4 times compared to the conventional cases.

Recently, diagnostics of plasma becomes more important due to requirement of precise control of plasma processing based on measurement of plasma characteristics. The Langmuir probe has been used for the diagnostics but it has an inevitable uncertainty and error sources such as incorrect tip length and RF noise. Instead of the Langmuir probe, various diagnostic methods have been developed and researched. The cutoff probe is promising one for plasma density using microwaves and resonance phenomenon at the plasma frequency. The cutoff probe has various advantages as follows; (i) it is simple and robust, (ii) it uses few assumptions, and (iii) it is free from deposition by reactive gas. However, the cutoff probe also has uncertainty and error sources such as gap between tips, tip length, direction of tip plane, and RF noise. In this study, the uncertainty and error sources in manufacturing both probes and in diagnostics process were analyzed via comparative experiment at various discharge conditions. Furthermore, to reveal the user dependence of both probes, three well trained Ph. D students made the Langmuir probe and the cutoff probe, respectively, and it were analyzed. Thought this study, it is established that reliability and validity of the Langmuir probe and the cutoff probe related with not only the intrinsic characteristics of probes but also probe user.

Background and Objectives: Cardiff Acne Disability Index(CADI) is one tool used internationally to measure the quality of life of acne sufferers. There, however, is a necessity of developing Korean version of CADI, as the questionnaires of the original one are written in English, making it hard to apply for Korean patients. So as a first step, we conducted a cross-cultural translation of CADI into Korean and verification of face validity. Methods: After properly translating CADI questionnaires into Korean up to guidelines for cross-cultural adaptation of health related quality-of-life measures, we conducted a survey with 122 undergraduates to get face validity, using the translated questionnaires. Results: About the translated CADI questionnaires, 86 out of 107 undergraduates replied that they had no difficulty understanding them, while 21 offered ideas about ambiguous expressions of them. Upon further examination of two oriental doctors, two sentences were additionally modified in the translated version. Conclusions: Firstly, we created the Korean version of CADI, one of the most effective methods in the world to measure acne sufferers' quality of life, by properly translated the original version into Korean. Then we conducted a survey for face validity with the translated questionnaires and gathered opinions from those questioned. After going through some examining and correcting procedures based on the opinions, we finalized the Korean version of CADI. It will also require a follow-up verification process to prove credibility and validity of the final version of Korean CADI.

Silsosangami(SSG) is a formula of oriental medicines as an effective biological response modifier for augmenting host homeostasis of body circulation. Also SSG has been known to have an anti-diabetic activity and anti-platelet aggregation activity. The present study was undertaken to examine the effects of a new SSG on murine macrophage and human neutrophil functions as well as on several enzymes relevant to the inflammatory process. The results of the present study indicate that SSG exerts anti-inflammatory effects related to the inhibition of neutrophil functions and of PGE2 production, which could be due to a decreased expression of and COX-2.
