  • 메타데이터 표준규격(이하 메타데이터 표준으로 기재)은 디지털 자원(Digital resource)의 장기보존 및 디지털 아카이브를 위해 필요한 기본 요소 중 하나로, 이는 현대 정보사회에서 중요한 요소로 잘 알려져 있다. 자원(Resource)의 기록관리와 아카이브, 장기보존을 위한 메타데이터 표준은 다양하며, AGRkMS, EAD, ISAD(G), OAIS, PREMIS5) 등이 이용되고 있다. 우리는 아카이브 시스템의 메타데이터 표준을 디자인하기 위해 목적에 따른 메타데이터 표준을 선택하고 맞춤화(Customization)하지 않으면 안 된다. 한편으로, 다른 시스템의 메타데이터 스키마와의 상호운용성(Interoperability)에 대한 고찰도 실시하지 않으면 안 된다. 이전 연구에서, 우리는 기록 생애 주기(Records lifecycle)라는 관점으로부터 메타데이터 표준의 특성에 대해 분석을 실시하였다. 이로 인해, 각 메타데이터 표준 요소가 해당하는 기록 생애 주기의 처음 단계를 확인할 수 있었고, 아카이브 혹은 보존을 위해서는 하나의 메타데이터 표준만으로 기록 생애 주기 전체를 포괄할 수 없다는 것을 보여 주었다. 우리는 이 분석을 통해서 기록 생애 주기의 단계와 메타데이터 표준간의 관계, 기록 생애 주기 전체에서의 메타데이터 특성은 볼 수 있었으나, 보다 상세한 분석을 실시하는 것은 앞으로의 과제로 남겨두었다. 지금까지의 연구에 근거하여, 본 논문은 기록 생애 주기의 관점에서 디지털 아카이브와 보존, 기록관리를 위한 메타데이터 표준의 특징 분석을 위해, 기록 생애 주기 안에서 실행되는 업무의 관점으로부터 메타데이터 스키마를 재 파악하고 분석하였다. 지금까지 메타데이터 스키마는 기술대상이 되는 자원을 중심으로 정의되었기 때문에 기록 생애 주기 전체와 생애 주기 안의 각 단계에서 이용되는 메타데이터 표준간의 매핑을 위한 적절한 방법이 없었다. 이에 본 논문에서는 각기 다른 메타데이터 표준의 기술 요소를, 기록 생애 주기에 포함시키는 업무와 연결시키는 것으로 메타데이터 표준간의 매핑 방법을 제안한다. 본 연구에서는 메타데이터 표준 분석을 위한 프레임워크(Framework)로, 기록 생애 주기를 이용하여 작성한 자원의 업무중심 모델, 즉 태스크 모델(Task Model)을 제안한다. 태스크 모델을 이용함에 있어서 업무를 실행하는 '이벤트(Event)'의 관점을 보다 명확하게 할 수 있다. 한편, 업무를 중심으로 기술 요소간의 매핑을 보다 효율적으로 실시하기 위해서는 요소를 카테고리 화하여 매핑의 대상 범위를 좁히는 것이 중요하다. 이를 위해 우리는 범용성을 가진 5W1H모델(Who, What, Why, When, Where, How)을 이용하여, 기술 요소를 카테고리 화 하는 것을 제안한다. 그리고 태스크 모델과 5W1H 모델을 이용하여 메타데이터 표준 요소에 특징을 부여하고, 요소 간의 매핑을 실시하여 표준 간 관계를 확인하였다. 태스크 모델은 기록 생애 주기 전체에 업무의 관점을 반영한 것으로, 이 모델을 이용함으로써 기록 생애 주기와 그 안의 각 업무에 대한 메타데이터 표준의 사용, 그리고 특징 분석을 위해 실시되는 기술 요소간의 매핑이 가능할 수 있었다. 또한, 5W1H 카테고리를 이용하여 업무와 자원에 관련되는 기술 요소간의 관계를 살펴보는 것으로, 관계가 명확해지는 것과 함께 조사대상을 좁히는 것이 가능하게 되었다. 이 프레임워크의 제안과 이용으로 우리는 특징 분석을 위해 실시되는 매핑 혹은 분류가 단순한 일반적인 매핑이 아닌 의미적인 분류를 할 수 있었다. 본 연구에서는 이 모델들을 이용하여, 메타데이터 표준간의 크로스워크를 정의하였다. 그리고 태스크 모델의 각 단계의 문맥 내에서 메타데이터 기술 요소의 특성을 매핑 예로 확인하고, 이를 바탕으로 하여 프레임워크에 대해 고찰하였다.

  • This paper makes an analysis of the ecological behaviours of 3 categories of quails, namely wild Japanese quails from the Weishan Lake Area, medium-sized domestic quails and pint-sized domestic quails. The study indicates as follows: (1) There is difference in morphological and biological habits between domestic quails and wild Japanese ones. (2) The cross-breeding between the wild and domestic quails is a cross from exclusion to affinity. (3) The behaviours of quails such as pursuit,paw and mating are selective. (4) The wild Japanese quails and domestic ones can succeed in mating and in reproducing fertilized eggs but with a low rate. (5) Evolutionary differentiation has been formed in varying degrees between the domestic quails and their wild ancestors in morphological and ecological characteristics.

  • Records from a total of 202 crossbred pigs were classified by their ear type and coat color to examine the presence of interrelationships with growth performances. Crossbred pigs were F2 generations of full sib family out of ten Landrace sows bred by 5 Korean domestic boars. Heavily drooped ear type was predominant, 195 out of 202 pigs over the other two types (1 straight and 6 slightly drooped). Coat colors were classified as four categories, all white, all black, dominant white or dominant black. Ratio among coat color categories did not fall within Mendelian principle of independence regarding two loci involved. There was dependency between ear type and coat color. However, due to rarity of ear types other than heavy drooped, dependency comes from distribution of those rare ear types. Three least squares models to test the effect of ear type and coat colors on growth performances were analyzed. First model analyzed effects on birth weight, body weight at 3 and 6 weeks and ADG' before weaning and between 3 and 5 weeks of age. This model included sex in addition to ear type and coat color. Second model analyzed postweaning growth traits (initial weight, final weight and ADG between these periods) upon initiation of performance testing. This model included effects of sex, test group and start age (as a covariate) in addition. Third model was fit for fasted weight before slaughter and included the effects of sex, test group and age at slaughter (as a covariate). The effects of sex and ear type were not significant source of variation for all traits. Test group was a significant source of variation for all the postweaning traits. Effect of coat color was not significant until the initiation of performance testing and became significant then after. Least squares means of dominantly black pigs were significantly lower than the other three coat colored pigs in final weight around 195 days of age and in ADG from the start of performance test and final weight measure.

  • A series of new liquid crystalline dimesogenic compounds with chiral tails was synthesized, and their thermal and liquid crystalline properties were studied. The chain length of the central polymethylene spacers (x) was varied from dimethylene (2) to decamethylene (12). These compounds were characterized by elemental analysis, IR and NMR spectroscopy, differential scanning calorimetry (DSC), and cross-polarizing microscopy. All compounds were found to be enantiotropically liquid crystalline, and the values of melting ($T_m$) and isotropization temperature ($T_i$) as well as enthalpy change (Δ$H_i$) and entropy change for isotropization (Δ$S_i$) decreased in a zig-zag fashion revealing the so-called odd-even effect as x increases. Their mesomorphic properties fall into three categories depending upon x; (a) compounds with x=2 and 4 formed two different mesophases, smectic and cholesteric phases in that order on heating, and vice versa on cooling, (b) compounds with x=3, 7, 8, 10 and 11 reversibly formed only the cholesteric phase, and (c) compounds with x=5, 6, 9 and 12 exhibited only a cholesteric phase on heating, whereas on cooling they formed two different mesophases, cholesteric and smectic phases, sequentially.

  • To study the full health effects of parental radiation exposure on the children of the atomic bomb survivors, the Radiation Effects Research Foundation developed a cohort of 76,814 children born to atomic bomb survivors (F1 generation) to assess cancer incidence and mortality from common adult diseases. In analyzing radiation-associated health information, it is important to be able to adjust for sociodemographic and lifestyle variations that may affect health. In order to gain this and other background information on the F1 cohort and to determine willingness to participate in a related clinical study, the F1 Mail Survey Questionnaire was designed with questions corresponding to relevant health, sociodemographic, and lifestyle indicators. Between the years 2000 and 2006, the survey was sent to a subset of the F1 Mortality Cohort. A total of 16,183 surveys were completed and returned: 10,980 surveys from Hiroshima residents and 5,203 from Nagasaki residents. The response rate was 65.6%, varying somewhat across parental exposure category, city, gender, and year of birth. Differences in health and lifestyle were noted in several variables on comparison across city and gender. No major differences in health, lifestyle, sociodemographics, or disease were seen across parental exposure categories, though statistically significant tests for heterogeneity and linear trend revealed some possible changes with dose. The data described herein provide a foundation for studies in the future.

  • Many studies on methane ($CH_4$) and nitrous oxide ($N_2O$) emissions from livestock industries have revealed that livestock production directly contributes to greenhouse gas (GHG) emissions through enteric fermentation and manure management, which causes negative impacts on animal environment sustainability. In the present study, three essential values for GHG emission were measured; i.e., i) maximum $CH_4$ producing capacity at mesophilic temperature ($37^{\circ}C$) from anaerobically stored manure in livestock category ($B_{0,KM}$, Korean livestock manure for $B_0$), ii) $EF_{3(s)}$ value representing an emission factor for direct $N_2O$ emissions from manure management system S in the country, kg $N_2O-N$ kg $N^{-1}$, at mesophilic ($37^{\circ}C$) and thermophilic ($55^{\circ}C$) temperatures, and iii) $N_{ex(T)}$ emissions showing annual N excretion for livestock category T, kg N $animal^{-1}$ $yr^{-1}$, from different livestock manure. Static incubation with and without aeration was performed to obtain the $N_2O$ and $CH_4$ emissions from each sample, respectively. Chemical compositions of pre- and post- incubated manure were analyzed. Contents of total solids (% TS) and volatile solid (% VS), and the ratio of carbon to nitrogen (C/N) decrease significantly in all the samples by C-containing biogas generation, whereas moisture content (%) and pH increased after incubation. A big difference of total nitrogen content was not observed in pre- and post-incubation during $CH_4$ and $N_2O$ emissions. $CH_4$ emissions (g $CH_4$ kg VS-1) from all the three manures (sows, layers and Korean cattle) were different and high C/N ratio resulted in high $CH_4$ emission. Similarly, $N_2O$ emission was found to be affected by % VS, pH, and temperature. The $B_{0,KM}$ values for sows, layers, and Korean cattle obtained at $37^{\circ}C$ are 0.0579, 0.0006, and 0.0828 $m^3$ $CH_4$ kg $VS^{-1}$, respectively, which are much less than the default values in IPCC guideline (GL) except the value from Korean cattle. For sows and Korean cattle, $N_{ex(T)}$ values of 7.67 and 28.19 kg N $yr^{-1}$, respectively, are 2.5 fold less than those values in IPCC GL as well. However, $N_{ex(T)}$ value of layers 0.63 kg N $yr^{-1}$ is very similar to the default value of 0.6 kg N $yr^{-1}$ in IPCC GLs for National greenhouse gas inventories for countries such as South Korea/Asia. The $EF_{3(s)}$ value obtained at $37^{\circ}C$ and $55^{\circ}C$ were found to be far less than the default value.

  • High concentration of $NH_3$, $CO_2$, and lots of dust are found in modern densely raising stall system, as results, they provide a negative influence on animal and lamer health, and production ability. Therefore, it is necessary to keep clean the inside of stall air to increase the productivity. A wet type air cleaner has been developed to clean the stall air. The work principle is that the inside air are sucked through the fan, and the rotating discs make a water into a fineness spray and blows into the stall. The spray can take the dust, $NH_3$, and odor from the stall inside air and give back to the circulating water, which can be refreshed in 2 hours interval. In the Present study, we measured the $NH_3$, dust, odor, temperature and humidity in a swine stall that were installed two wet air cleaners with 700 fattening swine with on-mode and off-mode of wet air cleaners. In fall, the concentrations of $NH_3$ in off-mode stall were maximum 24 ppm and minimum 16 prm, and the average was 18.2 ppm. However in on-mode stall the $NH_3$ concentrations were maximum 7ppm and minimum 1ppm, and the average was 2.7ppm. The concentration of $NH_3$ in on-mode was 74% lower than off-mode stall. Odor was measured by olfactometer. In the off-mode stall, the odor unit was 3,800 OU/$m^3$, but in the on-mode stall the odor unit was 2,100 OU/$m^3$ Odor removal efficiency was about 45% in on-mode stall. The dust measure was divided into 3 categories, $PM_{10}$, $PM_{2.5}$ and $PM_{1.0}$. Whereas the $PM_{10}$ showed no significant differences between the tests, $PM_{2.5}$ and $PM_{1.0}$ in the fine particle range reduced remarkably in the on-mode.

  • Growing and finishing Korean native bulls were used to investigate the effects of different dietary energy levels on performance and energy intake. Experimental observations were made over three weight categories (200 to 250 kg, 250 to 350 kg and 350 to 450 kg). Three diets (2.4, 2.6 and 2.8 Mcal ME/kg DM) were used for each weight category. Crude protein levels of the diets were 12, 11 and 10% for the respective weight groups. Dietary energy level did not significantly affect daily body gain within a weight range but daily body gain during the entire experiment was higher (P<.05) in bulls receiving 2.6 Mcal energy diet than in those fed 2.4 and 2.8 Mcal energy diets. The following equation was developed to predict daily body gain(Y) from energy levels(X) of ration. $Y\;=\;1.3.475X\;-\;2.5949X^{2}\;-\;16.355$ Increasing energy levels significantly (P<.05) decreased daily feed intake. The following equation was developed to predict daily feed intake(Y) from energy levels(X) of ration. $Y\;=\;-30.013X\;+\;5.4401X^{2}\;+\;49.119$ Feed intake per metabolic body size during the entire feeding period ranged from 100.9 to 110.8 g and was lower in bulls fed 2.6 and 2.8 Mcal energy diets than in those fed 2.4 Mcal energy diet. Increasing energy levels significantly (P<.05) improved feed efficiency. The following equation was developed to predict feed efficiency(Y) from energy levels(X) of ration. $Y\;=\;-118.34X\;+\;22.448X^{2}\;+\;162.85$ Daily energy intake during the entire experiment ranged from 18.90 to 19.99 Mcal and there was no significant difference among energy levels. Daily energy intake per metabolic body size during the feeding period ranged from 248.6 to 260.8 kcal and was slightly higher in bulls receiving 2.8 Mcal than in those fed 2.4 and 2.6 Mcal energy diets. Energy required per kg body gain ranged from 17.25 to 19.11 Mcal and was slightly lower in bulls receiving 2.6 Mcal energy diet than in those fed 2.4 and 2.8 Mcal energy diets.
