Objectives The purpose of this study was to develop the Sasangin Diagnostic Questionnaire for Specialist(SDQ_S) and to evaluate the reliability and validity of SDQ_S for standardization of sasang constitutional diagnosis by korean medicine Specialist in clinical practice.Methods SDQ_S was developed through discussions of three sasang constitutional medical specialist. We recruited 210 subjects aged from 20 to 70, and conducted the evaluation of SDQ_S and sasang constitutional diagnosis. For the reliability test, internal consistency was examined by calculating the cronbach's α coefficient on 88 items excepted measurements of trunk, and independence and agreement was examined by chi-square test and McNemar test for 84 subjects which retested SDQ_S. For the validity test, discriminant functions was derived from the sample group(105 subjects), and they were applied to the test group(105 subjects). We identified the hit-ratio of SDQ_S in the test group.Results and Conclusions In the reliability test, the cronbach's α coefficient was 0.664 and 87 items(98.9%) have dependent relationships between 1st test and 2nd test. And 39 items(44.3%) have high agreements(0.8≤McNemar), 26 items(29.5%) have common agreements(0.4≤McNemar<0.8). In the validity test, four discriminant variables(Soeum Index, Taeeum Index, Torso Ratio I, Taeyang Index) were selected, and two discriminant functions were derived. Total hit-ratio was 74.2%, and hit-ratio of Taeeumin(76.7%) was higher than that of Soeumin(75.9%) and Soyangin(69.7%). SDQ_S has good reliability and validity for sasang constitutional diagnosis.

Background: Although the consumption of vitamin beverages has increased because of the recent interest in health and beauty, guidelines addressing appropriate consumption habits are lacking. Thus, the aim of this study was to investigate the erosive potential of several vitamin beverages and to propose guidelines for the appropriate intake of these drinks. Methods: Five vitamin beverages were selected after a pre-investigation of the current beverage market. Coca-Cola and mineral water were selected as the control beverages. The pH of the beverages was measured with a calibrated pH meter, and the titratable acidity (TA) was determined by using 1 M sodium hydroxide to reach pH 5.5 (TA5.5) and 7.0 (TA7.0). The screening method suggested by the International Organization for Standardization was used to measure pH variation (ΔpH) by using an under-saturated hydroxyapatite solution to determine the difference between the initial and final pH of the screening solution. All measurements were performed in triplicate. Results: All vitamin beverages tested in this study exhibited a low pH (2.53~2.99), similar to Coca-Cola, which is known to be a highly acidic beverage. The highest TA5.5 and TA7.0 values of the vitamin beverages were 7.03 ml and 8.81 ml, respectively. The largest change in pH determined by using the screening solution was found in Bacchus D (ΔpH 1.44±0.05). The mean ΔpH of the vitamin beverages was 1.12±0.29, which was higher than that of Coca-Cola (positive control, ΔpH 0.58±0.05). Conclusion: Vitamin beverages exhibited an erosive potential capable of damaging enamel surfaces. Therefore, the frequency of vitamin beverage intake should be limited, and individuals consuming these drinks should try to restore normal oral pH as quickly as possible.

The measurement of hydration level in the surface layer of the skin, stratum corneum (SC), gives important information on the biophysical properties and function of the skin barrier such as softness, flexibility, and healthiness of the skin. But it is difficult to measure a consistent hydration level from a sample to another sample due to individual variations and environmental changes. The aim of this study was to evaluate objective hydration after using various products in the SC. The SC Hydration was measured by capacitance (Corneometer$^{(R)}$, C+K, Germany) on the ventral site of forearm from 40 healthy volunteers. The skin surface was chronologically measured immediately after application of the test products and 3 and 6 hours later. We analyzed the averages of five measurements of each site and used the hydration increase rate for correction on untreated site variation. We found that most polyols including glycerol and butylenes glycol influenced directly the hydration increase rate in the SC previously. In this study, glycerol was used to prepare the standard products from 0 to 20 percents and applied to the same volunteers. The individual standard curve showed linear relation to glycerol concentrations. Based on the the standard curve, hydration of SC was converted into hydration increase rate to glycerol concentrations. The converted glycerol concentrations of products were repetitive and reproducible. In addition, the individual standard curve was used to relate the skin type of each individual. These results suggest that the hydration of the SC standardized regardless of external variation and individual skin condition can explain detailed skin state variation. Further studies will be conducted with other ingredients such as surfactants, lipids and aqueous materials, and with other methods for noninvasive measurement.

Objectives : The objective of this study is to apply the contents of "WaHyul(訛穴 : The errors of acupoint locations"of "ChimGuKyungHumBang" to modern acupoint locations. Methods : The text of "WaHyul" was closely examined and analyzed. "WHO standard acupuncture point locations in the western pacific region" was reviewed based on its contents. Results : According to the analysis, the correct 少商(LU11) was mentioned as a spot appropriately distanced from the corner of the nail root under the skin. This is the most accurate and reasonable synthesis of other related texts. Furthermore, the necessity of defining the locations of all the well points was also emphasized and their locations were mentioned that could be located by the same method. There is no further discussion of other acupoints apart from descriptions of their locations from other texts. Some parts that were pointed out as common errors included not only commonly made mistakes, but errors made in acupuncture texts as were true for 神門(HT7) and 肩井(GB21). The standards of 少商(LU11), 合谷(LI4) and 足三里(ST36) presented in the WHO Standardization are not only similar to what 「WaHyul」 indicated as errors in acupoint locations, but also deviate other acupuncture texts; appropriate corrections must be made. The standard of 肩井(GB21) presents a new acupoint locating method never mentioned before in received classic acupuncture texts and so a rediscussion is in need. Other standards, such as the 絶骨(GB39), had some points of controversy, yet somewhat incomplete while HT7 did not go beyond the bounds of "WaHyul". Conclusions : "WaHyul" can be used to revise WHO standards, and has practical value in modern acupoint locating.

China is a country with a long history. Chinese culture dates back thousands of years ago. Thousand years of history left the huge quantity of archival heritage, which consists of the memory of China. From tied knots, tortoise shell, bronze, bamboo to paper, film, CD, the mankind's history is kept and continued through the evolution of the documenting media and documenting methods. In the information era, when we are immersed in the sea of information technologies, archivists, as guards of human's memory, have to look for a balance point between new and old, between unchanged and changed. On one hand, archivists should try their best to protect traditional archives in a usable, authentic way in a long term; on the other hand, they must face the challenges posed by electronic record. The information age is a stage of the social development of mankind, the digitalization of archives is an important progress of human history. The report mainly is composed of three parts of the content: first, introduce the preserving situation of Chinese archival heritage ; focus are put on "China archival heritage program" and the construction of "Special archives repository"; second, the process of digitalization of traditional archives; third, the framework of electronic record standard.

Objectives : We performed this study to search the best time for HRV measuring and which index has the validity in a short term measuring. Methods : At first, three examiner measured electrocardiogram(ECG) of 5 people(4 male + 1 female) for 20 minutes in two times. and we devided ten regions (0-5, 5-10, 10-15, 15-20, 0-10, 0-15, 0-20, 5-15, 10-20, 5-20 minutes). After that we finded the HRV index for each regions. To evaluate the validity, we used Gage Repeatability and Reproducibility Study by MINITAB(ver. 13.20). If the '%Study Var' is under 30 and 'Number of Distinct Categories' is over 4, we could tell it has validity(repeatability and reproducibility). Results : 1) The region and HRV index has repeatability and reproducibility, was HF index in 10-15 minutes. The HF index in 15-20 minutes gained 27.41(%Study Var) and 5(Number of Distinct Categories). 2) The HF index in 10-15 minutes has the better reproducibility than repeatability. The value of measurement is under the control. There is consistency among the examiner. The distribution of measurement is not large. There is no interaction between examiner and each people. 3) The HF index in 10-15, 0-10, 0-15, 0-20, 10-20 minutes was not enough to gain the repeatability and reproducibility. But it had some meanings ; %Study Var, Number of Distinct Categories is 32.68, 4 for 10-15 minutes, 34.43, 4 for 0-10 minutes, 34.44, 4 for 0-15 minutes, 33.56, 4 for 0-20 minutes, 32.07, 4 for 10-20 minutes. Conclusions : This study shows the best index of measuring HRV is the HF index in 15-20 minutes. So, from now on we should measure the HRV for 20 minutes and extract the HF index in 15-20 minutes. It must be the standard for HRV measuring.

The purpose of this study is to elaborate the request for proposal (RFP) for the localization parts development support project of core parts carried out by the Defense Agency for Technology and Quality. The RFP is the most important document throughout the localization parts project, including project announcement and developer selection, design and test of the development product, final evaluation, and standardization of the project. However, if the RFP is not established at the beginning of the project, there is an increased risk of business failure due to frequent changes by various reasons. In this study, we recognized the necessity of elaboration of RFP and applied the AHP method for quantitative elaboration. Eight requirements of the RFP related to the mechanical/electrical performance of localized development products and three elaboration methods for each requirement were designed in a hierarchical structure, and each weight was calculated by applying the 5-point scale AHP method. The AHP survey was conducted with 20 developers participating in the localization parts project, and the consistency ratio of the AHP survey result was less than 0.1. The elaboration method with the highest value among the calculated weights is classified, and the analysis results and future research directions of the elaboration method are presented.

Objectives: This study was conducted to evaluate the clinical effects of group therapy for Panic disorder patients based on Mindfulness & Li-Gyeung-Byun-Qi therapy. Methods: The FFMQ, BDI, STAI, STAXI, Panic attack, Anticipatory anxiety and subjective improvement of three Panic disorder patients were compared pre- and post-treatment when given Mindfulness & Li-Gyeung-Byun-Qi therapy. Results: 1) After the patient in case 1 underwent 5 weeks of group therapy for Panic disorder, the Mindfulness meditation score was slightly improved, anxiety and depression were significantly decreased, and expression of anger was also improved. In addition, the Panic attack and Anticipatory anxiety became more stable in the objective evaluation, while 'Extreme improvement' was shown in the subjective evaluation. 2) After the patients in case 2 and 3 underwent 5 weeks of group therapy for Panic disorder, Mindfulness meditation scores were slightly improved, anxiety and depression were significantly decreased, and expression of anger was also improved. In addition, the Panic attack and Anticipatory anxiety became more stable in the objective evaluation, while 'Moderate improvements' were shown in the subjective evaluation. Conclusions: As per the results in these cases, it was shown that group therapy for Panic disorder utilizing Mindfulness & Li-Gyeung-Byun-Qi therapy was effective to maintain meditation and control the emotions of anxiety, depression, anger and so on. Therefore, it was considered that expansion of clinical utilization through the standardization of a group therapy program for Panic disorder is needed. Furthermore, it was also considered that a comparative study of the effects of previous cognitive programs for Panic disorder according to the objectified and standardized manual is needed in the future.
