  • In pathologically analyzing, 'Qi(氣)' is fall downed 'Zheng-Qi(正氣; Base energy of human body)' or 'Wai-Gan-Xie-Qi(外感邪氣; poisoned energy from outside of human body)'. And all extroverted symptoms from this 'Qi(氣)' is 'Shang-Chong(上衝)'. Also this symptom's basic mechanism is deficiency of 'Zhong-yang(中陽; basic active energy acting pivot)' by non-proper 'Xia-fa(下法; treatment way getting out focus to down side)' at early days of 'Tai-Yang-bing (太陽病; Primary stage symptoms when the cold energy of the outside tresspasses the external layer of body)'. And comparing herbs in medicines for treating 'Shang-Chong(上衝)' in Shang han lun with Japanese in Shang-han medical practitioner's view, there is 'Ping-Chong(平衝; Supress out bursting energy)''s effect when use 'Gui-zhi(桂枝; Cinnamomum cassia loureirii zeylanuicum)' for mass dosage. Based on these, 'Qi-Shang-Chong(氣上衝)' means all of the symptom's aspects which called 'Yang(陽)''s aspect that is extrovesity, dynamic and imminent by results of the experiment about Cinnamaldehyde which are the main ingredients of 'Gui-zhi(桂枝; Cinnamomum cassia loureirii zeylanuicum)' and clinical data of 'Gui-zhi-tang(桂枝湯)'.

  • The present work used the efficiency transfer method used to calculate the full energy peak efficiency (FEPE) curves of the (2"*2" & 3"*3") NaI (Tl) detectors based on the effective solid angle subtended between the source and the detector. The study covered the effect of the self attenuation coefficient of the source matrix (with a radius greater than the detector's radius) on the detector efficiency. $^{152}$ An Eu aqueous radioactive source covering the energy range from 121.78 keV up to 1408.01 keV was used. In this study an empirical formula was deduced to calculate the difference between the measured and the calculated efficiencies [without self attenuation] at low and high energy regions. A proper balance between the measured and calculated efficiencies [with self attenuation] was achieved with discrepancies less than 3%, while reaching 39% for calculating values [without self attenuation] due to working with large sources, or for low photon energies.

  • In accordance with Korean structural foundation design standards, dynamic or static load tests are mandated for 1 to 3% of total piles. The construction quality of the remaining 97% to 99% of piles is determined through penetration measurements. This study aims to enhance the quality control of the majority of piles by adopting a pile driving formula that considers both penetration and hammer energy. The current challenge lies in adapting existing overseas driving formulas to the domestic site conditions, characterized by shallow weathered or soft rocks, and the prevalent use of pre-bored piles. To address this, the Modified Gates formula was refined using domestic dynamic load data, thereby improving its applicability to pile management. Despite employing fewer variables, the proposed formula demonstrates a comparable accuracy to dynamic loading tests in predicting the bearing capacity of pre-bored piles. Consequently, this formula holds promise for practical use in future pile quality management.

  • Several series of fracture tests were conducted to explore the fracture characteristics and to determine the fracture energy of concrete. A stable three-point bend test was employed to generate the load-deflection curves. The fracture energy may then be calculated from the area under the complete load-deflection curve. The initial notch-to-beam depth ratio (${\alpha}_0$/H) was varied from zero to 0.6. The prediction formula for the fracture energy of concrete is also derived and is found to depend on the tensile strength and aggregate size. The proposed fracture energy formula can be used for the fracture analysis of concrete structures. The present study also devises an equivalent crack length concept to predict the maximum failure loads of concrete beams. A simple formula for the equivalent crack length is proposed.

  • Background: Recently, Obesity has become a social problem in all over the world including Korea. Dietary regulation, exercise and behavior modification therapy are used in the treatment of obesity, but until now, there have been many difficulties in treating it. Objectives: To examine in obese pre-menopausal Korean females the short-term efficacy for weight loss of an herbal formula (Slim-diet). Design: A 6-week longituidinal evaluation of a herbal formula (Slim-diet) in 35 pre-menopausal females (baseline age $31.6\;{\pm}\;6.1$) with body mass index > $25kg/m^2$. Body composition was measured using bioimpedence analysis (BIA) and dual energy X-ray absorptiometry (DXA). Anthropometry was done by same observer. Total cholesterol, total lipid, triglyceride, and LDL-cholesterol were measured. Results: Herbal formula (Slim-diet) treatment produced significant loss of weight (P < 0.001), percent of body fat (P < 0.001, both BIA and DXA) and waist circumference (P < 0.001). It also produced significant reduction of total cholesterol and total lipid levels (P < 0.05).

  • The objectives of this study were to examine the growth pattern and hair trace element contents of healthy infants who were fed breast milk(BF infant) and formula (FF infant) during the first 6 months and its relationship to intake of trace elements. Bimonthyl anthropometric measurements were obtained on 32 infants through 6 months of age. Mean calculated energy, iron, zinc and copper intake from breast milk at 2 months of age were 432.4kcal/d, 0.19mg/d, 1.18mg/d and 0.22mg/d. The values obtained from formular were543.7kcal/d, 6.68mg/d , 2.82mg/d and 0.33mg/d , respectively. In spite of the significantly lower intake of energy and trace elements in BF infants than in FF infants, BF infants showed growth above the average Kroean infant standard growth rate and showed no significant growth rate difference or hair trace element content. Hair iron content in the BF infants at 6 mo. of age was positively related to birth weight and iron intake at 2 mo. of age. In contrast, hair zinc and copper content in the FF infants at 6 mo. of age as negatively related to height increment and weight increment during 6 months, respectively. These results support the suggesting that BF infant's higher iron, zinc and copper intake is attributed to the superior bioabailability of these trace elements from breast milk.

  • As pointed out in the OECD BEMUSE Program, when a high computation time is taken to obtain the relevant output values of a complex physical model (or code), the number of statistical samples that must be evaluated through it is a critical factor for the sampling-based uncertainty analysis. Two alternative methods have been utilized to avoid the problem associated with the size of these statistical samples: one is based on Wilks' formula, which is based on simple random sampling, and the other is based on the conventional nonlinear regression approach. While both approaches provide a useful means for drawing conclusions on the resultant uncertainty with a limited number of code runs, there are also some unique corresponding limitations. For example, a conclusion based on the Wilks' formula can be highly affected by the sampled values themselves, while the conventional regression approach requires an a priori estimate on the functional forms of a regression model. The main objective of this paper is to assess the feasibility of the ACE-RSM approach as a complementary method to the Wilks' formula and the conventional regression-based uncertainty analysis. This feasibility was assessed through a practical application of the ACE-RSM approach to the LOFT L2-5 LBLOCA PCT uncertainty analysis, which was implemented as a part of the OECD BEMUSE Phase III program.

  • The surveys of food intakes were carried out on 49 healthy infants aged 4-9 months at the first interview and repeated 3 more times at the interval of 2 months by using food diary recorded by their mothers. Of the subjects 12 were breast-fed, 28, formula-fed, and 9, mixed type-fed. Foods introduced first as the weaning food were commercial weaning foods, fruit juices, yoghurt, egg and rice. Supplemental food was introduced at the age of 4 months in 57% of the infants, but it amounted to a significant proportion of overall food consumption from the age of 6 months. The levels of nutrients except energy, iron and niacin were similar or in excess of RDA, and breast-fed infants tended to have lower intakes of energy and protein compared to infants formula-fed or mixed type-fed. Average intakes of vitamin A, vitamin B1, vitamin B2, vitamin C and calcium were above RDA, but iron intake did not meet RDA of infants of all ages. In conclusion, the average status of nutrient intakes of infants was fairly good, however, food consumption besides milk was less in breast-fed infants than in formula-fed infants, and iron status seemed to be poor, Although it is well-known that breast-milk compared to formulas is more beneficial for infants, mothers feeding breast-milk to their infants should be educated for the importance of supplemental food and its practice to support good nutrition.
