  • The present study was conducted to supply more scientific information for standardization of preparation method of Gyungdan and to determine the standard for manufacturing procedure adapted with mechanically impacting technology (MIT) for mass production. The optimum preparation condition for non-waxy Gyungdan adapted with MIT was 35% of water, 0.5% of wheat flour (w/w of soaked rice), and mechanically impacting for 10 min at 450 rpm. In the present study, standardization of manufacturing procedure for merchandizing of Gyungdan was established with width, weight, and height. Average of Gyungdan adapted with MIT at 90 rpm (stuffing speed) and 46.58 Herz (cutting speed) is 18.3 g of weight, 28.4 mm of height, and 32.4 mm of width. Hardness, as a main parameter of texture profile, of Gyungdan was maintained lower than 100 g up to 3 days at the storage of $20^{\circ}C$ and up to 70 days at the storage of $-20^{\circ}C$. And, it was performed to develop rice cake as meal-replacement adapted with MIT and sub-ingredients such as strawberry, pumpkin, and mugwort. Gyungdan prepared under controlling manufacturing condition of MIT was supplemented with 0-1.6% of sub-ingredients, respectively. In sensory tests, the best substitute ratios of strawberry, pumpkin, and mugwort were 1.6%, 0.8%, and 1.6%, respectively. With the results above, not-harden Gyungdan supplemented with sub-ingredients and various stuffs can be expected to application for wheat-substitute meal-replacement.

  • IPCC showed that calculation of climate vulnerability index requires standardization process of various proxy variables for the estimation of climate exposure, sensitivity, and adaptive capacity. In this study, four different methodologies of standardization methods: Z-score, Rescaling, Ranking, and Distance to the reference country, are employed to evaluate climate vulnerability-VRI (Vulnerability-Resilience Indicator) over Korean peninsula, and the error ranges of VRI, arising from employing the different standardization are estimated. All of proxy variables are provided by CCGIS (Climate Change adaptation toolkit based on GIS) which hosts information on both past and current socio-economic data and climate and environmental IPCC SRES (A2, B1, A1B, A1T, A1FI, and A1 scenarios) climate data for the decades of 2000s, 2020s, 2050s, and 2100s. The results showed that Z-score and Rescaling methods showed statistically undistinguishable results with minor differences of spatial distribution, while Ranking and Distance to the reference country methods showed some possibility to lead the different ranking of VRI among South Korean provinces, depending on the local characteristics and reference province. The resultant VRIs calculated from different standardization methods showed Cronbach's alpha of more than 0.84, indicating that all of different methodologies were overall consistent. Similar horizontal distributions were shown with the same trends: VRI increases as province is close to the coastal region and/or it close toward lower latitude, and decreases as it is close to urbanization area. Other characteristics of the four different standardization are discussed in this study.

  • A comparison of the analytical data obtained by three $k_0$-NAA software programs was carried out using both the airborne particulate matter collected from an urban site and the certified reference materials of the air filter and urban dust to evaluate the performance of the analysis. The individual $k_0$-NAA standardization methods of three countries, Korea, China and Vietnam which had been modified from the well established $k_0$-program were used for the comparative analysis. The measured concentrations of 30 elements from the two kinds of air samples based on this software were in agreement with each other within about 20% analytical error except for a few elements. By contrast, the results of China and Vietnam were moderately higher than that of Korea due to a systematic error associated with the detection efficiency, gamma peak analysis and geometric effect.

  • Objectives: The clinical document forms, a format for collecting clinical data, is the most fundamental object of standardization. Doctors must have a mutual understanding of the clinical chart. Methods: Clinical document forms were developed by investigating existing conditions in hospitals and conducting demand surveys, doing literature research, and seeking expert advice for the improvement of version 1.0. In addition, an organization of a network of 19 Oriental medical doctors and nurses, 190 patients, and users of collected and assessed data was formed to come up with version 2.0. Results: The overall format was divided into different portions that the patient, nurse, and doctor must fill out, respectively. The patient's section consists of demographic data, lifestyle details, history, and symptoms. The data to be supplied by the nurse include the patient's vital signs and anthropometric parameters. As for the doctors, they are to supply data regarding the patient's palpitation, the detailed symptoms of the patient's head, ophthalmological and otorhinolaryngological symptoms (mouth), respiration, circulatory organ and chest conditions, digestive-organ conditions (thirst), neuropsychiatric conditions, reproductive system, musculoskeletal system, skin (depilation), etc. Conclusions: Common clinical chart development is the prior question to Traditional Korean Medicine standardization. A web-based clinical document format should be developed to support diagnosis and treatment, and furthermore EMR (electronic medical record system) and EHR (electronic health record) developed. Clinical information could be shared through a network of medical institutions and be useful Traditional Korean Medicine for evidence-based medicine.

  • Purpose: Previous studies suggest that the concentration of 25-hydroxyvitamin D [25(OH)D] in cord blood may show an inverse association with respiratory tract infections (RTI) during childhood. The aim of the present study was to examine the influence of 25(OH)D concentrations in cord blood on infant RTI in a Korean birth cohort. Methods: The levels of 25(OH)D in cord blood obtained from 525 Korean newborns in the prospective COhort for Childhood Origin of Asthma and allergic diseases were examined. The primary outcome variable of interest was the prevalence of RTI at 6-month follow-up, as diagnosed by pediatricians and pediatric allergy and pulmonology specialists. RTI included acute nasopharyngitis, rhinosinusitis, otitis media, croup, tracheobronchitis, bronchiolitis, and pneumonia. Results: The median concentration of 25(OH)D in cord blood was 32.0 nmol/L (interquartile range, 21.4 to 53.2). One hundred and eighty neonates (34.3%) showed 25(OH)D concentrations less than 25.0 nmol/L, 292 (55.6%) showed 25(OH)D concentrations of 25.0-74.9 nmol/L, and 53 (10.1%) showed concentrations of ${\geq}75.0$ nmol/L. Adjusting for the season of birth, multivitamin intake during pregnancy, and exposure to passive smoking during pregnancy, 25(OH)D concentrations showed an inverse association with the risk of acquiring acute nasopharyngitis by 6 months of age (P for trend=0.0004). Conclusion: The results show that 89.9% of healthy newborns in Korea are born with vitamin D insufficiency or deficiency (55.6% and 34.3%, respectively). Cord blood vitamin D insufficiency or deficiency in healthy neonates is associated with an increased risk of acute nasopharyngitis by 6 months of age. More time spent outdoors and more intensified vitamin D supplementation for pregnant women may be needed to prevent the onset of acute nasopharyngitis in infants.

  • The seeds of Abrus precatorius L. (Family- Fabaceae) constitute the drugs Abrus, Gunja, or Ratti in commerce. In the Indian System of Medicine, the seeds are used for sciatica, paralysis, headache, dysentery, diarrhoea, leprosy, ulcer, nervous disorders, alopecia, as well as anti-inflammatory, antidiabetic, antibacterial, antitumor, sexual stimulant and abortifacient. Seeds are poisonous and therefore are used after mitigation. The protein abrin is responsible for the highly toxic properties of seeds. Quantitative HPTLC analysis of the methanolic extract of seeds determined the presence of 0.4018% gallic acid and 0.4009% glycyrrhizin. The present study was undertaken to develop an HPTLC method, as well as ascertain the physico-chemical, morphological and histological parameters to establish the authenticity of A. precatorius seeds.
