From the part "歷代醫學姓氏(Historic Doctors)" in "醫林撮要(Uirimchualyo)", the following has been noticed and concluded. 1. Because acupuncture was originated from stony needle, the word "石(sok)" contains the meaning of needle, and from this point on, words like 石(sok), 砭石(pyumsok), 箴石(Jamsok), 鑱石(Chamsok) had been derived. 2. The word 砭石(pyumsok) used in "Hwangjenaekyong(Yellow Emperor's Canon of Medicine or Hwangdineijing)" should be interpreted as acupuncture in a verb form, not a noun form. 3. 鑱石(Chamsok) or 鑱鍼(Chamchim) was used for surgical treatment for tumor, by cutting open tumors and pressing the pus out. Therefore, 砭石(pyumsok), 鑱石(Chamsok) are the same kind of needles, and 鑱鍼(Chamchim) is the tool improved from 鑱石(Chamsok) used in the Bronze Age. 4. Kwakpak put a note on 鑱石(Chamsok) in "山海經(Sanhaekyong)" that reads "it is defined as 砥鍼(Jichim) and treats tumor." This let us know the shape of 石(sok), 砭石(pyumsok), 鑱(Chamsok), 鑱鍼(Chamchim), and the stone that can be used as a surgical tool with slim & sharp shape is obsidian. 5. Because obsidian is only found around Mt. Baekdu and limited area in South Korea & Japan in Asia, it is closely related with the life & medical environment of the tribe "Mt. Baekdu". 6. The development of 鑱鍼(Chamchim) was influenced by surgical treatment used in early stage of civilization, and its origin is traced upto Gochosun dynasty. Korea's own traditional medical knowledge is derived from this surgical treatment skill. 7. Because the acupuncture is originated from Gochosun dynasty, 鍼(chim) was derived from 箴(Jam) of 箴石(Jamsok), 䥠(Chim) & 䥠(Chim) both were used for a time being, and finally settled into 鍼(Chim). 8. The word 針(Chim) showed up at Myung dynasty, and started to be used in Korea from early Chosun dynasty. 9. In the early Chosun dynasty, 鍼(Chim) was used for medical term, and 針(Chim) for non-medical term. In the mid Chosun dynasty, 針(Chim) was used as a term for tool, and 鍼(Chim) as a term for acupunctural medical treatment. 10. Under the order of King Sunjo, Dr. Yesoo Yang published "醫林撮要(Uirimchualyo)", added "醫林撮要續集(Sequel to Uirimchualyo)", and added "歷代醫學姓氏(Historic Doctors)" again which eventually made totally 13 books of "醫林撮要(Uirimchualyo)". In addition, many parts of "醫林撮要續集(Sequel to Uirimchualyo)" were quoted in "東醫寶鑑(Donguibogam)", and influenced much in publishing "Donguibogam". 11. In "歷代醫學姓氏(Historic Doctors)" of "醫林撮要(Uirimchualyo)", the same way in "Donguibogam", referred to 針(Chim) as a term for a needle, and 鍼(Chim) as a term for Acupuncture. 12. From the usage of 針(Chim) & 鍼(Chim), shown in "鄕藥集成方(Hyangyakjipsungbang)", "醫林撮要(Uirimchualyo)" and "東醫寶鑑(Donguibogam)", we can notice the spirit of doctors who tried to take over the legitimacy of Korean tradition, and their elaboration & historical view that expresses confidence on our own medical technology, through the wording 鍼(Chim).

Concrete is known as a heterogeneous product which is composed of complex chemical composition and reaction. The development of concrete thermal effect during early age is critical on its future structural health and long term durability. When cement is mixed with water, the exothermic chemical reaction generates hydration heat, which raises the temperature within the concrete. Consequently, cracking may occur if the concrete temperature rises too high or if there is a large temperature difference between the interior and the exterior of concrete structures during early age hydration. This paper describes the contribution of novel Fabry-Perot (FP) fiber optic temperature sensors to investigate the thermal effects of concrete hydration process. Concrete specimens were manufactured under various water-to-cement (w/c) ratios from 0.40 to 0.60. During the first 24 hours of concreting, two FP fiber optic temperature sensors were inserted into concrete specimens with the protection of copper tubing to monitor the surface and core temperature change. The experimental results revealed effects of w/c ratios on surface and core temperature developments during early age hydration, as well as demonstrating that FP fiber optic sensors are capable of capturing temperature variation in the concrete with reliable performance. Temperature profiles are used for calculating the apparent activation energy ($E_a$) and the heat of hydration (H(t)) of concrete, which can help us to better understand cement hydration.

Previous studies have shown that plant-based vegetarian diets, which typically contain a variety of antioxidants and dietary fiber, help reduce the risk of heart disease, diabetes, obesity, and cancer. However, some studies have reported that vegetarian diets can lead to deficiencies in protein and trace minerals compared to non-vegetarian diets. This study was conducted to compare anthropometric measurements, blood parameters, dietary intake, and hair mineral status in long-term vegetarians (MV; moderate vegan, LV; lacto-ovo vegetarian) and non-vegetarians (NV). Thirty MV (12 males, 18 females; mean age, $50.58{\pm}5.05$ years), 15 LV (11 males, four females; mean age, $49.45{\pm}4.97$ years), and 30 NV (15 males, 15 females; mean age, $48.90{\pm}3.62$ years) participated. No significant differences were observed for age, height, weight, or body mass index, but body fat was significant lower in MV and LV males than that in NV males. White blood cell counts of MV, LV, and NV male subjects were significantly different. Dietary intake data showed that plant protein and plant iron intake were significantly higher in MV and LV than those in NV. Animal protein, animal fat, and animal iron intake were significantly higher in NV than those in MV and LV. A hair mineral analysis showed that calcium and iron were higher in the hair of MV and LV than those in NV. Zinc concentration in hair was not significantly different among the groups. The results suggest that vegetarian diets are adequate to sustain mineral status to at least the same degree as that of non-vegetarian diets.

A clinical study was made on 365 low birth weight infant and 406 normal birth weight infant who had been born at Kangnam St. mary's Hospital during past 3 years from Jan. 1, 1995 to Dec. 31, 1997. the data of this study were gathered through reviewing of medical records. 1. Comparison of general characteristic with of obstetric characteristic 1) Old maternal age, previous abortion and previous LBWI delivery in the group of low birth weight infant(LBWI) mother were more prevalent than those in the group of normal birth weight infant(NBWI)mother 2) Cesarean section, abnormal presentation and multiple pregnancy in the group of LBWI mother were prevalent than those in the group of NBWI mother. 3) regular antenartal care and visiting rate of tertiary hospital in the group of LBWI mother were more prevalent than those in the group of NBWI mother. 2. Frequency of low birth weight infant 1) Anmual average frequency of LBWI was 6.5% and monthly frequency was the highest in January and december. 2) The frequency of LBWI was the highest in 37-40wks of gestational age and was the highest in 2251-2500 gm of birth weight. 3) The frequency of congenital anomaly in the group of LBWI was more prevalent than that of NBWI. 3. Mortality rate of LBWI The mortality rate of LBWI was 9.2%. The highest mortality rate was noted before 27wks of gestational age, less than 1000gm of birth weight and within 12hrs of delivery. 4. The most common complication of pregnant women was pre-term labor, the most complication relating to placenta was premature rupture of membrane(PROM) and the most fetal complication was fetal distress in delivered LBWI. 5. Significant relating factors of low birth weight infant delivery were associated with maternal age, previous delivery, previous low birth weight delivery, pre-eclampsia, anemia, oligohydramnios, PROM, placenta previa, abruptio placenta, fetal sex, fetal distress and congenital anomaly.

The clinical experience of 2,340 inguinal hernia repaired by one pediatric surgeon on 2,079 children at Hanyang University Hospital from September 1979 to December 1993 was analyzed. Of 2,046 patients who had primary hernia repairs at Hanyang University Hospital, 1,636 were male and 410 female, and 55.5% of hernias occurred on the right side, 36.0% on the left, and 8.6% were bilateral. The patients presented hernia under the age of 12 months were 45.3% and those performed herniotomy under the age of 12 months were 25.5%. Birth weight was less than 2.5kg in 111 patients(8.7%) of 1,279 data available patients. Ninety(6.6%) of 1,354 data available patients were premature(<37wks gestation). The proportions of bilateral inguinal hernia and the onset age under 12 months of life in low birth weight babies and premature babies were higher than in full-term babies. Incarcerated inguinal hernia occurred in 327 patients(16.0%) of whom 8 patients were strangulated hernias. The occurrence of incarceration inversely related with age of patients. The subsequent contralateral inguinal hernia following unilateral hernia repairs occurred in 80 patients(4.3%) among which 72 were male and 8 were female. The incidence of contralateral inguinal hernia was more frequent in boys(4.8%) than girls (2.2%) and in cases after left herniotomy(6.4%) than after right herniotomy(2.9%). Sixty percent of contralateral inguinal hernia developed within 1 year after primary hernia repair. The recurrence of inguinal hernia occurred in 6 patients(0.27%) treated at our hospital primarily. There were one or more associated congenital anomalies in 83 patients of which congenital heart diseases were the most common. Sliding hernia occurred in 25 patients consisted of 5 boys and 20 girls. Family history was noted in 35 patients and there were 28 sets of monozygotic and 3 sets of dizygotic twins.
