  • The study area is mostly composed of Precambrian Gyeonggi gneiss complex, Jurassic Daebo granites, Cretaceous tonalite and dykes, and so on. On the basis of field survey and mineral assemblage, the granites can be divided into three types; biotite granite (Gb), garnet biotite granite (Ggb) and two mica granite (Gtm). They predominantly belong to monzo-granites from the modes. Field relationship and K-Ar mica age data in the surrounding area suggest that intrusive sequences are older in order of Gtm, Ggb and Gb. Gb and Ggb, major study targets, occur as medium-coarse grained rocks, and show light grey and light grey-light pink colors, respectively. Mineral constituents are almost similar except for opaque in Gb and garmet in Ggb. Gb and Ggb have felsic, peraluminous, subalkaline and calc alkaline natures. In Harker diagram, both rocks show moderately negative trends of $TiO_2$, MgO, CaO, $Al_2O_3$, $Fe_2O_3$(t), $K_2O$ and $P_2O_5$ as $SiO_2$ contents increase. Among them, $TiO_2$, MgO and CaO show two linear trends. From the trends and the linear patterns in AFM, Sr-Ba and Rb-Ba-Sr relations, it is likely that they were originated from the same granitic magma and Ggb was differentiated later than Gb. REE concentrations normalized to chondrite value have trends of parallel LREE enrichment and HREE depletion. One data of Ggb showing a gradually enriched HREE trend may be caused by garnet accompaniment. Ggb have more negative Eu anomalies than Gb, suggesting that plagioclase fractionation in Ggb have occurred much stronger than that in Gb. In modal (Qz+Af) vs. Op, Gb and Ggb belong to magnetite-series and ilmenite-series, respectively. From the EPMA results, opaques of Gb are magnetite and ilmenite, and those of Ggb are magnetite-free ilmenite or not observed. Bimodal distribution of magnetic susceptibility reveals two different granites of Gb (332.6 ${mu}SI$) and Ggb (2.3 ${mu}SI$). Based on the paleomagnetic analysis as well as modal analysis, the main susceptibilities of Gb and Ggb reside in magnetite and mafic minerals, respectively. They belong to S-type granite of non-magnetic granite by susceptibility value. In addition, $SiO_2$ contents, $K_2O/Na_2O$, A/CNK molar ratio and ACF diagram support that they all belong to S-type granites.

  • This study aimed to provide the fundamental data on the field of cosmetics by comparing heavy metal concentration in terms of domestic/foreign products, types and colors. The study determined the concentrations of lead, cadmium, arsenic, chromium, antimony, nickel, copper and cobalt in cosmetics such as lipstick, lip gloss, lip balm, foundation and eye liner. From the period of January to August, 2013, 121 samples were collected from cosmetic stores distributing to the general market. The average metal concentrations were as follows; $0.663{\mu}g/g$ for lead, $0.010{\mu}g/g$ for cadmium, $0.056{\mu}g/g$ for arsenic, $1.144{\mu}g/g$ for chromium, $0.008{\mu}g/g$ for antimony, $0.405{\mu}g/g$ for nickel, $0.319{\mu}g/g$ for copper and $0.108{\mu}g/g$ for cobalt. Except for chromium, the heavy metal concentrations were significantly higher in foreign products than in domestic products (p < 0.05). Also, The mean concentrations of heavy metal were significantly different (p < 0.05) when classified by cosmetic type. The highest mean concentrations shown in lipstick were $1.430{\mu}g/g$ of chromium, $0.616{\mu}g/g$ of lead and $0.385{\mu}g/g$ of nickel, in foundation $1.155{\mu}g/g$ of lead and $1.023{\mu}g/g$ of chromium. In eye liner, the highest mean concentrations were $1.424{\mu}g/g$ of chromium and $0.830{\mu}g/g$ of nickel. Additionally, The concentrations of heavy metal were significantly different by color (p < 0.05). Brown colored cosmetics were found to have the highest mean concentrations of chromium, nickel and copper, ivory colored cosmetics the highest mean concentrations of chromium and lead, and pink colored cosmetics the highest concentrations of lead and chromium.

  • This study was conducted to investigate the effect of curing additives on color property of smoked duck meat. Curing process of samples was performed one of the following treatments: C, non-curing: T1, 2.43% salt: T2, 2.43% salt + 0.49% tripolyphosphate (TPP): T3, 2.43% salt + 0.49% TPP + 0.002% nitrite: T4, 4.76% duck seasoning: and T5, 1.47% salt + 0.24% TPP + 0.2% L-ascorbic acid. Instrumental meat color of both breast and thigh of smoked duck showed that the CIE $a^*$ value of the T4 was significantly (p<0.05) higher than that of the other treatments, whereas T5 had a significantly (p<0.05) higher CIE $b^*$ value than the other treatments. In results of nitroso pigment, T5 of smoked duck breast was significantly (p<0.05) higher value compared to other treatments, whereas T3 and T5 of smoked duck thigh had a significantly (p<0.05) higher value than other treatments. Heme pigment contents of control and T5 was significantly (p<0.05) higher value compared to other treatments in smoked duck breast. Meat color of T3 by sensory evaluation showed redder (p<0.05) than other treatments. These results suggested that using L-ascorbic acid is revealed to be pink color without nitrite or pigment when manufacturing of smoked duck meat.

  • In order to elucidate the effects of copper on Corassius carassius, the following were studied: 1) lactate dehydrogenase isozyme patterns by cellulose acetate electrophoresis, 2) LDH activity and copper effect on LDH enzyme system y spectrophotometry, 3) esterase isozyme patterns by agar thin layer electrophoresis, 4) hemoglobin patterns by starch gel electrophoresis, and 5) histological study. 1. There were two bands of LDH isozymes (LDH-3 and LDH-5) in the gill, three bands (LDH-2, LDH-4, and LDH-5) in the liver, and two bands (LDH-3 and LDH-4) in the muscle of the normal fish. The LDH-1 bond was not found in the above three tissues. When the fish were exposed to copper, LDH-3 appeared in the liver, LDH-5 in the muscle, but no new LDH band appeared in the gill. 2. The sepcific activities of the LDH were lowest in the gill and highest in the muscle of the normal fish, and they were gradually decreassed in the gill and highest in the muscle of the normal fish, and they were gradually decreased in the liver and mucle except in the gill from 1-day to 10-day exposure to copper. It indicates that LDH activities in the liver and muscle of the fish were inhibited by copper. 3. Through in vitro experiment, it is clear that the decrease of the LDH activities of the liver and muscle of the fish exposed to copper is mainly caused by the inhibition on the M-LDH in the fish. 4. The numbers of the esterase isozyme bands of the gill, liver, muscle, blood, brain, and kidney of the normal fish were 3, 6, 2, 2, 2, and 2 respectively, and these numbers were the same as those exposed to copper. The relative mobilities of the esterase bands in the gill, liver, blood, and kidney of the exposed group were different from those of the control. 5. There was one hemoglobin band on the anode in the normal fish. It seems that the nobility of hemoglobin band of the fish exposed to copper was slightly faster than that of the normal fish. 6. The normal gill lamellae of the fish consisted of centrally located pillar cells and a number of mucus cells. When the fish were exposed to copper, the epithelial layer was divorced first, disintegrated, and then destroyed completely. 7. The liver of the normal fish had prominent central veins, cords of hepatic cells, and sinusoids. When the fish were exposed to copper, numerous droplets of fat appeared in the cells around the central vein of the liver. It is assumed that the fatty droplets were accumulated by the lesion due to fatty metamorphosis of the liver caused by copper. 8. There was no histological difference between the muscle of the normal fish and that of the fish exposed to copper. 9. In the normal fish, the tubules of the kidney were surrounded by hemopoetic tissues. However, the kidney tissue of the fish exposed to copper received some damage on the proximal tubules. Since the tubule cells were reduced in height, the lumens of the tubules were enlarged. Consequently many proximal tubules exhibited some pink-stained granular casts and various stages of degeneration.

  • The Stele for National Preceptor Hongbeop from the Jeongtosa Temple site in Chungju is one of the most important stone cultural heritage items for exemplifying the style of the Goryeo era. Despite its obvious value, this relic has been stored in a weathered condition at the National Museum of Korea. It had suffered various dismantling and displacements during the Japanese colonial period and had long been exposed in the open air. The stele was selected as a subject for the Stone Monuments Restoration Project launched by the National Museum of Korea in 2015. In preparation for its outdoor exhibition as part of the restoration project, this study investigated the characteristics of its materials, produced a map of its deterioration from weathering, and carried out ultrasonic analysis of the materials to provide findings useful for conservation treatment. The materials analysis revealed that the turtle-shaped pedestal of the stele was made from two-mica granite consisting of medium-grained quartz, plagioclase, alkali feldspar, biotite, and muscovite. Its body stone is crystalline marble, the rock-forming mineral in which is medium-grained calcite in a rose-pink color with dark grey spots. The dragon top of the stele is made of crystalline marble, the major component of which is medium-grained calcite of a light-grey color. The deterioration consists of 21.5% abrasion on the stone body, with its south face most damaged, and 18.6% granular disintegration, with the north face most damaged. The ultrasonic material characterization conducted for mapping the general condition of weathering shows low values on the parts-assembly area of the turtle-shaped pedestal and on the upper portion of the stone body. It is considered that there is dislocation due to partial blistering and fracturing as well as to the differences in surface treatment. Prior to the outdoor exhibition of the stele, the surface was cleaned of contaminants and was consolidated based on the scientific investigation in order to prevent weathering from the external environment.

  • The total acidity (TA) of Makgeolli was affected by suspended solids and $CO_2$ produced during the fermentation process. Nine Makgeollis (four sterilized and five unsterilized Makgeollis) were collected in the market, and their TAs were compared before and after filtration and $CO_2$ removal. TAs of sterilized Makgeollis were 0.379~0.477%, which significantly decreased to 0.167~0.225% after filtration and 0.132~0.170% after $CO_2$ removal (P<0.05). TAs of unsterilized Makgeollis were 0.412~0.467% and decreased to 0.157~0.365% after filtration and 0.143~0.280% after $CO_2$ removal (P<0.05). TAs of Makgeollis were compared by three methods using different indicators. The TAs of sterilized and unsterilized Makgeollis were 0.105~0.123% and 0.105~0.200%, respectively, by bromthymol blue+neutral red (light green), 0.129~0.154% and 0.130~0.255%, respectively, by phenolphthalein (faint pink), and 0.120~0.146% and 0.130~0.232%, respectively, by bromthymol (blue). Nowadays, Makgeolli is commercialized with various distinct colors, and thus it is important to select appropriate indicators for proper titration endpoint identification for TA measurement. The compositions of organic acids profiles varied depending on sterilized or unsterilized Makgeollis, in which oxalic acid (0.108~0.329 mg/mL), malic acid (ND to 0.134 mg/mL), lactic acid (0.127~0.776 mg/mL), and citric acid (ND to 1.159 mg/mL) were found, and lactic acid was in unsterilized more than sterilized Makgeollis.

  • To investigate the characteristics of edible flowers as a food material, we have examined the kinds, colors, sizes, fresh weights, pigments and shipping periods of edible flowers marketed on the cropping farms, selling agencies and Internet shopping malls from February through September, 2005. Thirty six kinds of edible flowers were marketed in Korea, and all but the chrysanthemum were introduced species. The characteristics of edible flowers were shown differently by the varieties following the same kinds of flowers. Those colors were yellow (twenty five kinds), red (twenty three), pink (twenty), white (eighteen), and orange (sixteen). Flower diameters were measured and showed that seven kinds of edible flowers were 1.0 to 2.0cm, fourteen 2.0 to 3.0cm, sixteen 3.0 to 4.0cm, eight 4.0 to 5.0cm, and nine over 5.0cm. Flower fresh weights were measured as follows: twenty one kinds of edible flowers were under 0.5g ($58.3\%$), eight were $0.6\∼1.0g(22.2\%$), and six were $1.1{\∼}1.5g(16.7\%$). The taste of edible flowers was often bitter (twenty one kinds), sweet and sour (seven), somewhat fragrant (six), fishy (three), and others (nine). The pigments of edible flowers were anthoxanthin (twenty seven kinds), flavonoid (twenty three), carotenoid (seventeen), and betanidin (four).

  • We determined the genetic relatedness among 81 commercial varieties of oyster mushrooms by either comparison of fruiting body characteristics or using PCR amplification with URP primers. Also, we assessed their temperature adaptation by using box cultivation. Based on our data, some varieties such as Wonhyung and variety 1, Suhan and variety 20, Wang-hukpyung and variety 4, Chunchu #2 and variety 6, Shinong #11 and variety 1, Samgu #1 and variety 2, showed the close genetic relatedness between each other. It is known that mushroom culture room is affected by outer temperature because mushroom need the adequate aeration for their growth. Therefore, in aspect of saving energy, the cultivation of season favorable mushroom species has been recommended. Eight different commercial varieties including Sa-chul, Yeoreum and Bunhong(Pink) grew well at high temperature ($16^{\circ}C$). Also, about 51 different oyster mushroom strains were good at relatively high temperature. However, other 64 different oyster mushroom varieties were grew well at low temperature ($11^{\circ}C$). Fourty-nine varieties were adapted well in most temperatures. The slow growth rate were observed in some varieties including Kun(P. eryngii ), Awi(P. nebrodensis ), and Cheunbok(P. abalonus ), which are not suitable for box cultivation. We believe that the culture characterization of each mushroom varieties should help many farmers in many aspects such as saving energy, quantity improvement and new variety development etc.

  • This study was aimed to provide the fundamental data about oxidized hair color products. For this reason, we collected 125 oxidized hair color products, which were distributed in domestic market from January to October, 2012, and measured the heavy metal concentrations of lead, arsenic, cadmium, chromium, manganese, nickel, copper in the samples. Results were compared by domestic, foreign, henna, type and color. The average metal concentrations were as follows; 0.211 ${\mu}g/g$ for lead, 0.008 ${\mu}g/g$ for cadmium, 0.051 ${\mu}g/g$ for arsenic, 0.954 ${\mu}g/g$ for chromium, 6.250 ${\mu}g/g$ for manganese, 0.591 ${\mu}g/g$ for nickel and 0.544 ${\mu}g/g$ for copper. In case of lead and arsenic, the concentrations were much less than the regulated amount (20 ${\mu}g/g$ and 10 ${\mu}g/g$, respectively) suggested by MFDS (Ministry of Food and Drug Safety). In henna (p < 0.05), the concentrations were significantly higher than those of other domestic and foreign oxidized hair color products as follows; 1.264 ${\mu}g/g$ for lead, 0.267 ${\mu}g/g$ for arsenic, 0.025 ${\mu}g/g$ for cadmium, 4.055 ${\mu}g/g$ for chromium, 72.044 ${\mu}g/g$ for manganese, 3.076 ${\mu}g/g$ for nickel and 4.640 ${\mu}g/g$ for copper. Statistically, it showed that the heavy metal concentrations were quite different for the different types of hair color products. The cream and liquid type products had the highest average concentration in chromium (0.708 ${\mu}g/g$, 0.478 ${\mu}g/g$, respectively). On the other hand, powder type products showed the highest concentration in manganese (60.041 ${\mu}g/g$). In addition, the concentrations of heavy metals and the color of products are not quite correlated. It was shown that average concentrations of lead and chromium were higher for yellow, chromium for red and pink, manganese for brown and black, and nickel for green.

  • The Purpose of this study is to examine closely the causes influenced upon the comfort and recovery of the woman delivered of a child in the hospital at the same time to understand environmental status of hospitals in order to promote mother's health recovery, and to improve hospital environment by emphasizing the meaning of environment and health before the medical staff and hospital administrative authority. In the method of servery of the research, 165 post paestum patients have been randomly selected who were accommodated and delivered their babies at OB(obstetric ) & GY (Gynecologic) unit the 7 general hospitals for the period of 6 December 1976 through 17 December 1976. As for the survey, it has been used of Questionnaire where we have 65 items in the respect of personal environment in the hospital such as trusting nurse, ability, reliability, kindness and etiquette of nurse and tile character of nurse the relationship with patients the other respect of physical environment included 9f temperature, moisture. air-ventilation lightening noise, cleanness. facilities, and the third realm being of mother's hearth ground to have the following conclusion 1. The feature of the collected personnel they are from OB or GY sects of from OB unit of the other 5 hospitals except the two general hospitals of the college or school Otherwise the rate of the patients to nurses would be 9 : 1. As for the nurses'ground it would be appeared of 20-25 years of age as the 76%. either 3 year course or 4 year course in the education would be each 50% and less than 2 year experience case would record as of 60 %. In the respect of hospital physical environmental status, there we have two hospitals without any thermometers, on the other han4 nowhere there's hygrometer, otherwise, the lightening is normal or over than normal As for the structure of noise protection the corridors're, generally speaking worse than rooms, nerver hueless, there's no ventilating system in the hospitals. The rooms'repainted in white and yellow, light green white, or green color. The patient's clothing were in green pink blue, light green or in white co for. There're not anything special in both decoration and equipments. Most of them used tall beds except in one hospital 2. To the extent of perception of patient's hatch 9round and hospital environment it is presented that they perceived nurse's ability in highest in total human variable, though perceived kindness or etiquette in the lowest otherwise, comparatively high in total average. 3. In the respect of physical environment it is highest perceived of lightening terms, otherwise, lowest perceived of air ventilation and total average became lowest than the one of the original record 4. To ages, in the respect of hatch ground rather old aged mother than the younger one has perceived that nurse would be trusting, in good service character, able, at the same time, liable, Otherwise, in physical environment regardless of age, they perceived lightening in high and remarkably lower in ventilation As a result of the examination of the difference in hospital environment to each age it is appeared of statistical difference at 5% level of ability in the personal environment otherwise little difference as for physical environment 5. In the respect of perceiving level to educational standard it is highly perceived of personal environment for higher ranking group rather than lower group in the educational standard. In case of physical environment it is highly perceived for lower level group rather than higher level group in educational background. The variables which have statistical significance at 5% level are from trusting kindness, etiquette and total kindness, etiquette and total all significance at 5% level are from trusting, kindness, etiquette and total human environment variable in personal environment, otherwise, there's little difference in the physical environment. 6. The perceiving level due to times of admission and accommodation at the hospital would be cleared out as gradual higher perception both physical and personal environment in the hospital. At 5% significant level of the ventilation condition in physical environmental variable it is presented of meaningful difference otherwise, there we have little difference both in Personal variable and other one. 7. In accordance with living standard, the perception degree of personal environment in tee hospital would be inclined to increase to higher living standard on the other hand, in case of the physical environment, the perception level world increase to lower living standard At 5 % level, the trustuariable and total scores in the personal eicuironmectal variable there appeared a meaningful/ significant difference otherwise, there presented little difference both in physical environmental and other variable to the living standard 8. Pertaining to family unit, the mother of an independent family unit perceived highly in all respect of the personal and the physical environment in the hospital rather than the woman of succeeding family unit. At 5 % level there appeared a difference in the respect of kindness and etiquette both in personal environment variable, on the other hand, there hardly marked a difference between other variable and physical environmental one. 9. The degree of perception to comforting level has little connection with a statistical difference the age, educational level hospital admitting times, living standard or family unit. 10. The most effective variable to mother's comforting level will be nurse's ability, reliability, trusting manner, and total physical environment variable in order.
