Background The purpose of this study was to clarify fading, red, green, and blue values (RGB) change, and color reproducibility for nipple-areola complex (NAC) tattoos. Methods NAC tattooing was performed on 60 sites in 59 Japanese patients prospectively. The evaluation was assessed using digital photo, Casmatch standardization, and RGB and luminance values preoperatively, immediately after, 1 week, 1, 3, 6, and 12 months after tattooing. RGB and luminance values changes over time, time-adjusted fading rate, and the rate of luminance at 12 months were calculated. In color reproducibility study (n = 34), RGB values after 12 months were compared with the color sample about dark/reddish and light/less reddish pigments. Results RGB varied widely from immediately after to 1 month after tattooing. For RGB and luminance, significant differences were seen between pre and immediate after, 1 and 3 months, 3 and 6 months, and 6 and 12 months. In G values, significant differences were seen between all neighboring points. The fading rate tended to decrease as time progresses, but was not significant, that is, fading continued even between 6 and 12 months. Luminance was 9% brighter than contralateral NAC at 12 months. Color reproducibility tended to be higher with dark/reddish pigments, despite no significant differences. Conclusion The fading rate of tattooed NACs tended to decrease as time progresses, but fading still occurs between 6 and 12 months. Luminance was 9% brighter than contralateral NAC at 12 months after.

Objective : Mu-yi (蕪荑, Ulmi Semen Pasta) is the fermented product of the seeds of Ulmus macrocarpa Hance (Ulmaceae) or other species of Ulmus genus mixed with adjuvant materials. The medicinal origin and preparing method of Ulmi Semen Pasta are different from those in the past literature. Therefore, medicinal origin of Ulmi Semen Pasta and its preparation method were investigated by literature study. Methods : The classic and contemporary literatures from Korea, China, and Japan regarding to Ulmi Semem Pasta were searched to find the time-based changes of Ulmi Semen Pasta preparation and its origin. Results : The fruit or seed of U. macrocarpa has been medicinally used as Mu-yi (蕪荑) or Mu-yi-in (蕪荑仁) respectively in Korea, China, and Japan until early in 20th century. However, from the middle of the 20th century, the fermentation was performed in medicinal preparation of the fruit or seed of U. macrocarpa mixed with various adjuvant materials such as clay, Chrysanthmi Flos, Ulmi Cortex, etc. The roles or evidences of those adjuvant materials have not been clearly explained, which could not guarantee the consistent quality of Ulmi Semen Pasta. Conclusion : Current preparation method of Ulmi Semen Pasta have challenges in terms of quality maintenance, standardization, and marketing. Therefore, it is suggested that apparent evidence of current preparation method should be established or intact botanical part (seed or fruit) could be used as medicinal part.

Purpose: ISO (International Organization for Standardization) has published the third edition of ISO 3951-1:2022, Sampling Procedures for Inspection by Variables-Part 1. ISO 3951-1 is an AQL (Acceptable Quality Limit) type sampling scheme, and incorporates switching rules to move among normal, tightened, and reduced inspections. This paper examines the contents of ISO 3951-1:2022 and analyzes its characteristics. Methods: The contents of ISO 3951-1:2022 and ISO 3951-1:2013 (the second edition of ISO 3951-1) are compared and analyzed in detail. The comparisons of ISO 3951-1:2022 and ISO 2859-1:2013 (the latest edition of Sampling Procedures for Inspection by Attributes-Part I) are also performed. Results: The main changes of ISO 3951-1:2022 are as follows: i) procedures have been introduced to accommodate measurement uncertainty, ii) many of sampling plans are adjusted to improve the match between their OC (operating characteristic) curves and the OC curves of the corresponding plans of ISO 2859-1, iii) the form p* for determining the acceptance of the lot is extended to all ranges of AQL and code letter values. Conclusion: ISO 3951-1:2022 cancels and replaces ISO 3951-1:2013, which has been technically revised. KS Q ISO 3951-1:2019 that is Korean version of ISO 3951-1 was established as a Korean standard by conforming to ISO 3951-1:2013. Therefore, we need to revise it to ISO 3951-1:2022, as soon as possible.

Background: ABO antibody titration is useful for the evaluation of ABO-incompatible bone marrow or solid organ transplantations, yet the results quite vary between different test methods used. We compared the results of microcolumn agglutination and tube methods. Methods: Anti-A and anti-B isoagglutionin titers were determined in 63 healthy individuals (23 O, 20 A, and 20 B blood groups) using 4 different methods: immediate spin tube (tube), microcolumn agglutination without anti-human globulin (AHG) (CAT), tube with AHG (tube-AHG) and microcolumn agglutination with AHG (CAT-AHG). Results: The median (range) titers of anti-A and anti-B in group O individuals by tube, CAT, tube-AHG, and CAT-AHG methods were 64 (8-512), 64 (8-512), 128 (8-2,048), and 128 (16-2,048); 64 (16-128), 128 (16-256), 128 (16-512), and 256 (16-512), respectively. The median (range) titers of anti-A in group B and anti-B in group A individuals by the four methods were 64 (16-128), 128 (8-128), 128 (8-256), and 256 (8-256); 64 (8-128), 64 (8-128), 32 (8-128), and 64 (8-256), respectively. The isoagglutinin titer measured by CAT-AHGmethod was the highest. The titers measured by CAT and CAT-AHG methods were 0-1 titer higher than those by tube and tube-AHG methods, respectively. Whatever method was used, the isoagglutinin titers were higher in women than in men. Conclusions: CAT-AHG was the most sensitive method among the four methods tested. Since AHG titer values are critical for the clinical management and CAT has less manual procedures than tube method, CAT-AHG method could be used for the standardization of ABO antibody titration in different institutions.

Purpose : Since 1967, The Korean Pediatric Society and Korean Government have developed Korean Growth Standards every 10 years. Last version was published in 1998. During past 40 years, Korean Growth Standards were mainly descriptive charts without any systematic nor statistical standardization. With the global epidemic of obesity, many authorities such as World Health Organization (WHO) and United States' Centers for Disease Control (CDC) have been changed their principles of growth charts to cope with the situations like ours. This article summarizes and reviews the whole developmental process of new 2007 Korean Growth Charts with discussion. Methods : With the initiative of Division of Chronic Disease Surveillance in Korea Centers for Disease Control and Prevention, we have performed new national survey for the development of new Standards in 2005 and identified marked increase of childhood obesity and plateau of secular increment of final height in late adolescents. We have developed new Growth Standards via adapting several innovative methods, including standardization of all available raw data, which were acquired in 1997 and 2005 national survey and full application of LMS method. Results : We could get new standardized charts; weight-for-age, length/height-for-age, weight-for-height, head circumference-for-age and BMI-for-age. Other non-standardized charts based on 2005 survey data were also published; waist circumference-for-age, mid-arm circumference-for-age, chest circumference-for-age and skinfold-for-age. Clinical guideline was also developed. Conclusion : Developmental process and results of new Korean Growth Charts are comparable with other internationally well-known Growth Standards, WHO 2006 Growth Standards and CDC Growth Charts. 2007 Korean Growth Charts are relevant especially in Korea and Korean ethnic groups.

While academic discussions and methodological researches on oral history are being progressed in Korea, its exploitation has already begun to increase with a variety of methods and approaches in the private sector. Oral history is a new method of research, as well as another process of production of archives. In order to make valuable and highly qualified archives of oral history with the application of the aforementioned conditions and characteristics, its recognition, environment, process, and method should be improved and developed. From this point of view, it is regarded as reasonable that oral history is recognized as a part of the strategy for documentation. Oral history should be produced based on common sense and reasonable judgment, applying empirical know-how rather than logic or principles because it holds a great number of characteristics, which include variable elements in the field of oral history. In addition, its process or documentation methods should be improved and developed, giving consideration to thorough exploitation. The promotion or revitalization of oral history is a signal that announces the advent of new archives and the new subjects of history at the same time. Endeavors to produce highly efficient archives of oral history are expected to be continued with the complex accumulation of empirical assets achieved at academic discussions and its fields.

This study investigated the association between $PM_{2.5}$ concentrations obtained with portable real-time monitors and those obtained with gravimetric methods in national urban air-quality monitoring sites in Seoul, South Korea. We used the SidePak AM510 Personal Aerosol Monitor (TSI Inc., 500 Cardigan Road Shoreview, MN) and DustTrak DRX 8533 (TSI Inc., 500 Cardigan Road Shoreview, MN) as portable real-time monitors for measuring $PM_{2.5}$ concentrations and compared these values with those measured with the PMS-103 or SEQ 47/50 models operated by Federal Reference Method (FRM) or the European Committee for Standardization(ECS), respectively, in national urban air-quality monitoring sites in Seoul. Measurements were conducted every other day in the winter and spring seasons of 2014. The estimated daily mean concentrations of $PM_{2.5}$ ranged between 13.4 and $161.9{\mu}g/m^3$ using AM 510 and between 22.0 and $156.0{\mu}g/m^3$ using DustTrak. The Spearman correlation coefficient for $PM_{2.5}$ concentrations between AM 510 and gravimetric results was 0.99, and the correlation between DustTrak and gravimetric results was 0.87. The correction factor suggested was 0.42 and 0.29 for AM 510 and DustTrak, respectively. We found that $PM_{2.5}$ concentrations measured with real-time monitors could overestimate true $PM_{2.5}$ concentrations and therefore the application of a correction factor (0.43) is strongly suggested for quantification when Real-time monitors were operated of $PM_{2.5}$ levels at urban atmospheric environment of South Korea.

As Korean cuisine is one of our cultural assets and has global potential, it needs to be better marketed and known to the world. However, there is a lack of research examining what to and how to globalize Korean cuisine practically. Therefore, the purpose of this study is to suggest fundamental reasons and ways to globalize Korean cuisine from a multicultural point of view. A Delphi method was selected because the study is suitable for a structured group of experts instead of unstructured groups or individuals. A panel of experts were selected from two groups, Korean experts and international experts. This research established the characteristics of Korean foods, the difficulties of Korean cooking methods and the incorporation or substitution of Western ingredients in two rounds. A panel of experts suggested strategies for globalizing Korean cuisine in the third round. As a result, meaningful solutions were suggested such as increasing the global profile and knowledge of Korean cuisine from 18 experts out of 23, developing various cooking methods for Korean-cuisine having distinctively Korean characteristics from 17 experts out of 23, developing recipes that are compatible with equipment and appliances in a western kitchen, and considering the differences in taste and texture(mouth-feeling) between Korean and the Western people.

Objective: The purpose of this study was to invigorate the use of infrared thermal imaging apparatus as a diagnostic tool in Oriental medicine by providing standard temperature on specific acupoints. Methods: Subjects for the study was recruited through an advertisement in the school homepage(www.sangji.ac.kr) explaining the objectives and methods. 100 volunteers agreeing to terms were selected and measured the full body thermal image. Common acupoints used in the clinical surrounding were chosen and final 63 acupoints were selected for the measurement. Male/female and right/left readings were obtained for the analysis. Results: Following results were obtained from analyzing the body temperature of 50 male subjects and 50 female subjects 1. Subjects participating in the study ranged from 19 years of age to 44 years. Median male age at $26.86{\pm}6.02$ and female age at $22.88{\pm}2.74$, respectively. 2. For all acupoints, no significant differences were witnessed between the gender and right, left side of the body. 3. 10 acupoints from the facial region(18 bilateral), 8 acupoints from the chest/abdomen region(10 bilateral), 6 acupoints from the back region(11 bilateral), 17 acupoints from the upper extremity(34 bilateral), and 22 acupoints from the lower extremity(44 bilateral) were chosen. 4. In the facial region, BL2 showed the highest temperature and GV26 showed the lowest. 5. In the chest/abdomen region, CV22 showed the highest temperature and CV6 showed the lowest. 6. In the back region, GV14 showed the highest temperature and BL23 showed the lowest. 7. In the upper extremity region, jianqian(extra point) showed the highest temperature and baxie(extra point) showed the lowest. 8. In the lower extremity region, KI1 and bafeng(extra point) shoed the highest temperature and BL40 showed the lowest. Conclusions: Based on the standard body temperature measured on specific acupoints throughout the body, we hope these findings can trigger further studies on applications of infrared thermal imaging and clinical usage in the field of oriental medicine.
