In-service diagnoses of pipeline facilities are important for a systematic maintenance of them. Field applications by using sealed gamma-ray sources $(^{60}Co,\;^{137}Cs)$ were performed to identify the heterogeneous zone in the pipelines of a distillation tower and a flare stack respectively. From the results, the heterogeneous zones in the pipelines were successfully identified. In the case of the pipeline connected to the distillation tower, a vapor pocket was detected in the fluid under hydrodynamic conditions, which could explain the reason for a decrease of the flow rate. In another case, an area with some amount of catalyst deposits was found at the bottom of the gas pipeline which was connected to the flare stack. And these findings provided important information for the process operators. Diagnosis technique by using gamma radiation sources has been proven to be an effective and reliable method for providing information on a media distribution in a facility.

Hepatocellular carcinoma (HCC) is one of the most prevalent malignant diseases worldwide and a leading cause for death in Asia, where the major risk factors are chronic hepatitis B virus and hepatitis C virus infection. Because most HCC patients die within 3 to 6 months from the time of diagnosis, searching for a new treatment has become more urgent for HCC than other cancers because there is no existing effective systematic therapy. In Korea and Asia, traditional herbal medicine is frequently administered to patients with advanced HCC. We present a HCC case where complete regression was observed after taking herbal medicine. Since the specific mechanism is unknown, we cannot determine whether the herbal preparation had a direct effect on the regression of HCC. Nevertheless, this case provides us a reason and hope for further research.

The rapid development of artificial intelligence (AI), including deep learning, has led to the development of technologies that may assist in the diagnosis and treatment of diseases, prediction of disease risk and prognosis, health index monitoring, drug development, and healthcare management and administration. However, in order for AI technology to improve the quality of medical care, technical problems and the efficacy of algorithms should be evaluated in real clinical environments rather than the environment in which algorithms are developed. Further consideration should be given to whether these models can improve the quality of medical care and clinical outcomes of patients. In addition, the development of regulatory systems to secure the safety of AI medical technology, the ethical and legal issues related to the proliferation of AI technology, and the impacts on the relationship with patients also need to be addressed. Systematic training of healthcare personnel is needed to enable adaption to the rapid changes in the healthcare environment. An overall review and revision of undergraduate medical curriculum is required to enable extraction of significant information from rapidly expanding medical information, data science literacy, empathy/compassion for patients, and communication among various healthcare providers. Specialized postgraduate AI education programs for each medical specialty are needed to develop proper utilization of AI models in clinical practice.

It is different from the DongEuiBoGam(東醫寶鑑) of Korea traditional medicine that China BeunJungLonChi(中醫辨證論治) was made for the scientific and systematic assortment of China medicine. Symptom(症)is more important than symptom complex(證)in china BeunJungLonChi at DonEuBoGam. And unusual symptoms generally are diseases in DongEuiBoGam. DongEuiBoGam is emphasis on body form, temper, body color, pulse(形氣色脈) and the functional difference of organs by body form and body color. there are many problems in order to unify the theory of Korea traditional medicine by china BeunJungLonChi. I suggest that a new assortment that can combine Sasang constitutional medicine(四象醫學), Constitution-Acupuncture(體質針), and Hyungsang medicine(四象醫學) will be necessary. BeunJungLonChi : diagnosis and treatment based on overall analysis of symptoms and signs, the cause, nature and location of the illness and the patient's physical condition according to the basic theories of traditional Chinese medicine

The purpose of this study is to develop the education program for a healthy family support center. This will be a representative program which will differ from the education programs of other welfare centers. This study suggests 11 themes based on the elements of a healthy family. These programs aim to prevent and solve family problems. The 11 themes are as follows: family values, family relations 1 and 2 (couple/parent-children), parent coaching 1 and 2, family culture, resource management, multi-cultural families, working families, family volunteerism, and family consulting. This study focuses on creating a frame for this program which is integrated, systematic, and flexible. It also develops both family diagnosis sheets and educational content about various aspects of family life. Thus, this can be a core program which allows networking with other programs.

Fault detection has to be proceeded by steady state filtering to get rid of transient effect associated with thermal capacity. Coefficient of variance (COV), ratio of standard deviation devided by moving average, was employed as steady-state filter. Engine speed and refrigerant pressures were selected as parameters representing system dynamics. The filtered values were registered as members of steady-state DB. They were found to show good functional relationship with ambient temperature. The relationship was fitted with a second order polynomial and the distribution bounds of the data around the fitted curve were expressed by visual inspection because of varying average and random data interval. Fault data were compared with the steady-state data obtained during normal operation. The fault data were easily isolated from the fault-free one. To make such isolation reliable, tests to construct good DB should be designed in a systematic way.

Objectives These prescribing recommendations have been written to guide clinicians on the appropriate use of Bangpungtongseong-san(BT) and Bangkihwangki-tang(BH) in the treatment of obesity. These recommendation are aimed at providing evidence based information concerning diagnosis and management of obesity. Methods We collected all relevant references about treatment effect of BT and BH on obesity in the forms of meta-analysis, systematic review, randomized controlled trial, case-control study, observational study and practice guideline from international and domestic databases and paper journals. We examined treatment effect, side effects, recommendations for dose, indication and contraindication of BT and BH. Results The treatment effect of BT and BH on obesity has been proved through clinical trial. BT is indicated for obese patients (Body mass index, $BMI{\geq}25$) with strong abdomen and a tendency to constipation, BH is indicated for obese patients ($BMI{\geq}25$) with a fair skinned, soft muscled, edematous and sweat easily. Conclusion We wish the information contained in theses recommendations will help clinicians reach a reasonable and beneficial decision with evidence-based results. Further studies are strongly needed to develop better treatment strategies for herbal medicines on obesity.

Objectives : The results from randomized controlled trials on traditional medicine have been negative or ambiguous. The appropriateness of the research methodology started to be questioned. However, the research methodology appropriate for studying traditional medicine has not been well-established. This study aims to explore the appropriate research methodologies for clinical studies on acupuncture. Methods : Clinical researches evaluating the efficacy and effectiveness of acupuncture for back pain were systematically searched and evaluated focusing on research methodology. The acupuncture treatment protocol is evaluated by 9 items which is individual treatment based on diagnosis, combining proximal and distal acupoints, exact location of acupoint, De Qi, adequate stimulation, duration of acupuncture, treatment sessions, treatment interval, and establishing relationship between patients and doctors. Results : Systematic review of acupuncture researches on low back pain suggested that observational studies and pragmatic trials rather than explanatory studies could incorporate these elements. Qualitative studies also could help understanding complex characteristics of acupuncture treatment which could not be evaluated by quantitative studies. Conclusions : In designing clinical researches on acupuncture, various study designs, especially observational study and pragmatic study, should be considered according to research objectives and subjects. The efforts to incorporate the core characteristics of acupuncture practiced in everyday clinical setting are also essential.
