고추장 담금시 첨가하는 물 대신 pineapple 과증에 딸기, 사과, 대추, 토마토 과즙을 혼합 첨가하여서 제조한 고추장의 성분은 다음과 같다. pH는 담금직후에 5.35~5.43였으며 이후 감소하는 현상을 보여 120일에는 4.80~4.91였다. 각 시험구간의 pH는 큰 차이는 보이지 않았다. 아미노태 질소는 담금직후에 57~99mg%에서 120일에는 161~175mg%로 증가하였다. 각 시험구간의 차이는 근소하난 숙성 전과정을 통하여 딸기 혼용구가 과즙 무첨가구에 비하여 다소 높게 나타났다. 유리당의 함량은 glucose, fructose, maltose의 순이었으며, 유리당 함량이 가장 높았던 120일에는 딸기 혼용구, 과즙 무첨가구, 복합과즙 혼용구의 순으로 높았고 사과 혼용구는 가장 낮았다. 환원당 함량은 시험구간에 큰 차이는 없는 편이나 숙성 중기까지는 과즙 무첨가구가, 60일 이후에는 대추 혼용구가 대체로 높았다. Protease의 활성은 숙성과정 중 대체로 증가하였는데 딸기 혼용구와 복합과즙 혼용구가 과즙 무첨가구에 비하여 활성이 높았다. β-Amylases는 담금직후에 5.20~5.90%를 나타내었으나 60일에는 6.25~17.88%로 활성이 최대에 달하였으며 과즙 무첨가구와 복합과즙 혼용구가 다소 높은 활성을 보였다. EthyI alcohol은 담금직후에 0.8~5.4mg%로 극미량이었으나 120일에는 561~1,568mg%로 급격히 증가하였다. 시험구별로 보면 대추 혼용구와 복합과즙 혼용구가 가장 높았고, 과즙 무첨가구가 가장 낮았다. The compositions of kochujang with various mixed fruit juices instead of water were analyzed during the 120 days of fermentation. At the beginning stage of making, pH were in the range of 5.35 ~5.43, and decreased as fermentation time passed. After 120 days, pH were in the range of 4.80 ~ 4.91. At the beginning stage of making, contents of amino nitrogen were in the range of 57 to 99 mg% and after 120 days fermentation, 161~175 mg% were. There was little difference of amino nitrogen among the groups. During the fermentation, the amino nitrogen contents of strawberry juice group was higher than that of control group. The order of free sugar contens detected in kochujang was glucose, fructose and maltose. Free sugar contents of kochujang were high after 120 days of fermentation for control group. Protease activity was increased during fermentation, and the strawberry juice group and the mixed fruit juice group showed higher protease activity than control group. At the beginning stage of making, the contents of ethyl alcohol were in the range of 0.8 to 5.4 mg%, and these were rapidly increased to reach 501~1,568 mg% after 120 days. Alcohol contents of the jujube juice group was higher than any other groups.

In this paper, the way that input voltage and input line current as a control variable is provided as one unit is projected. Till now, have dealed with three phase balanced load. But, in that case, total power factor compensation is difficult, for to control each phase at unbalanced load. Therefore, in this paper suggest of the scheme that three phase unbalanced load is controlled by each phase and input total power factor is compensated unit input factor. Therefore, in this paper suggest that three phase unbalanced load is controlled and the method in compensation of unit input factor to be attended by unbalanced load. Besides, the object of control is calculating quantity for input voltage and input line current for the point at issues make to improve of control method at unbalanced load. As a result, control system of each phase could maintain as unit input total power factor has been state diviation error of 2% with unbalanced load.

고상반응법(solid-state reaction)으로 산화물 초전도체 Bi_2-xGe_xSr_2CaCu_2O_8+8(x=0, 0.1, 0.2, 0.3, 0.4, 0.5)을 제조하여 치환에 따른 산소량의 변화가 초전도 특성에 미치는 영향에 관하여 조사하였다. 이차 가압(intermediate press) 방법으로 제조한 시편은 온도 폭 △K(온도 임계온도 T_c^on과 영저항 임계온도 T_c^zero와의 차)가 상당히 감소함을 알았으며 80 K 단일상 고용한계는 Ge 치환량이 x<- 0.3영역임을 알았다. 고용한계 영역 내에서 Ge 치환량 x의 증가에 따라 격자상수 c가 감소함을 보였으며, 온셋 임계온도 T_c^on은 증가하였고, 과잉(여분) 샨소량은 감소함을 보였다. Samples with the nominal composition, Bi_2-xGe_xSr_2CaCu_2O_8+8(x=0, 0.1, 0.2, 0.3, 0.4, 0.5) were prepared by the solid-state reaction method. We have studied the effect of substitution Ge for Bi and investigated the superconducting properties by changing oxygen content with Ge substitution. It was found that temperature difference, △K, between T_c^on and T_c^zero was considerably smaller in the samples prepared by the intermediate pressing method than that in the samples by the solid-state reaction method. We found the solubility limit of Ge to the 80 K single phase, the onset critical temperature T_c^on increased and excess oxygen content decreased with increase of x.

In a capacitor-discharge impulse magnetizer, a magnet is magnetized by the discharging current of capacitor The actual construction of magnetizing fixtures and discharge matching is expensive and time-consuming. Since the parameters of the impulse magnetizer have been determined and the resistance and inductance of such a magnetizing fixture can be easily computed using FEA, it is possible to predict the performance of such a fixture without actually building it. This paper describes that by mathematically modeling the capacitor-discharge impulse magnetizer fixture the problem can be solved with resonable predictability. The basic equations are presented and used to predict the magnetic-field intensity inside the fixtures. Finite-Element-Analysis is also used as part of the design process

REITs 유형별 과세 형태 분석에 의한 투자수익률 연구

김봉수(Kim, Bong-Soo) 글로벌경영학회 2008 글로벌경영학회지 Vol.5 No.4

전 세계적인 금융위기 속에서 정부는 다양한 정책적 수단을 활용하여 부동산 경기의 활성화를 유도하고 있다. 그러나 단순한 법적, 과제제도의 완화로 부동산 경기를 살리려 한다면 이전에 겪었던 부동산 투기 상황이 재연될 가능성이 농후하다. 따라서 부동산에 대한 직접적 투자를 활성화 할 것이 아니라 간접투자를 통하여 부동산 경기를 조절하는 것이 적절할 것으로 판단된다. 부동산에 대한 직접 투자는 물리적으로 한정된 부동산 자산에 대한 과수요를 유발하여 가격 상승을 초래하게 되고 이 러한 가격 상승은 투자자들에 대한 과도한 투자수익률을 기대하게 만들어 또 다른 초과수요를 만드는악순환적 결과를 유발할 것이다. 이러한 부동산 직접 투자의 대안으로 REITs에 대한 기대가 높아지고 있다. REITs의 활성화를 통하여 일반 서민들에게는 안전하고 안정적인 부동산 투자처를 제공하여 부동산 투자로 인한 수익을 향유할 수 있게 하고, 전문적인 부동산 투자자들에게는 높아진 세제상의 문제를 회피하고 다양한 부동산 포트폴리오를 구성할 수 있는 투자 대안을 제공할 수 있을 것이다. 그런데 일반 서민과 전문 부동산 투자자를 유인하기 위한 결정적인 요인은 결국 그들이 만족할 수 있는 투자수익률을 제공하는 데 있고 이것이 앞서 언급한 모든 목표들을 달성할 수 있는 REITs 활성화를 위한 기본 전제 조건이라 할 수 있을 것이다. 본 연구를 통하여 자기관리REITs, 위탁관리REITs 및 CR-REITs의 가상의 투자수익률을 살펴보았는데 그 결과 자기관리REITs의 경우 세제상의 문제로 인하여 일반 회사와 투자수익률에서 별 차이가 없었고 나머지 두 가지 유형의 REITs와는 비교할 수 없을 정도로 불리한 투자수익률을 보이는 것으로 나타났다. 분석결과에 따르면 자기관리REITs의 경우 개인이 직접 투자를 하는 것에 비하여 세제상의 이득이 전혀 없고 오히려 불리할 것으로 나타나고 있으므로 REITs의 본질적 목적을 달성하기에는 문제가 있는 것으로 판단된다. 따라서 자기관리REITs에 대한 법인세 면제를 위한 정책적, 법률적 고려가 있어야 할 것이며, 전체 REITs에 대한 세제상의 혜택도 개인 및 법인이 부동산에 대한 직접 투자보다 유리하다고 실감할 수 있는 수준까지 낮추어 부동산 투자자금을 REITs에 유인할 수 있도록 해야 할 것이다. This study examined the concept and theory on REITs, and tried to draw some suggestions by researching the systems of USA, the model of Korean REITs, and of Japan where REITs are now all the rage even if it was introduced at the same time with Korea. And then Korean REITs system and their condition of foundation were investigated. Finally some problems why self-management REITs are not activated are derived focusing on taxation system regarding to REITs. First, the benefit of tax exemption should be given to self-management REITs. Second, all of acquisition and registration taxes should be exempted and sunset article be rescinded. The solution of this problem is very important to activate REITs market. In order to improve the soundness of Korean realestate market, the government should give the institutional support and revise the tax code for REITs.

In order to investigate that blood lead levels of lead exposed workers is associated with decreased performance in neurobehavioral tests in adults, we investigate 78 workers in a battery industry. Three items among neurobehavioral core test battery of World Health Organization, including digit span, Santa ana dexterity, digit symbol were administered to workers occupationally lead exposed workers by operational guide for the WHO neurobehavioral core test battery. Blood lead (PbB) and zinc protoporphyrin in whole blood (ZZP) were selected as an index of lead exposure. Detailed occupational history such as exposed agent, age, work duration, smoking and drinking habits, were recorded as confounding factors. After controlling age, the results of digit span and digit symbol among the neurobehavioral tests were significant contributed by PbB.

연작업자들에서의 δ -aminolevulinic acid dehydratase 유전형질의 다형성이 신기능에 미치는 영향

δ-aminolevulinic acid hehydratase (ALAD) is a polymorphic enzyme that has two alleles, ALAD1 (ALAD1-1 as phenotype) and ALAD2 (ALAD1-2 or ALAD2-2 as phenotype). ALAD genotype has been reported to modify the toxicokinetics of lead. To investigate the influence of ALAD genotype polymorphism on renal function in lead workers, author studied 1022 male lead workers and 149 non lead workers in the same industries. For the cross-sectional renal function indices, blood urea nitrogen (BUN), serum creatinine, uric acid and total protein were selected. Blood lead and blood zinc protoporphyrin were also measured as indices of lead exposure. Information on weight, age, job duration, smoking & drinking history were collected. Following results are as follows: 1. Whereas the mean (standard deviation) of blood lead and blood ZPP of lead workers were 27.2±12.5 ㎍/㎗ and 57.7±37.8 ㎍/㎗, those of non-lead workers in the same premises were 14.9±6.5 ㎍/㎗ and 44.6± 15.8 ㎍/㎗ respectively. The difference of mean blood lead and blood ZPP between two groups were statistically significant. 2. Whereas the prevalence of the variant allele, ALAD2 in 1022 lead workers was 10.2 %, the prevalence of that in 149 non-lead workers was 7.4 %. But there was no difference of prevalence between two groups. 3. The mean±standard deviation of blood lead of subjects with ALAD1 was 25.5± 12.7 ㎍/㎗ and was slightly lower than that of subjects with ALAD2 (26.5±10.9 ㎍/㎗), and the mean±standard deviation of blood ZPP of subjects with ALAD1 was slightly higher than that of subjects with ALAD2 (56.7±37.3 ㎍/㎗ vs 48.9±18.6 ㎍/㎗). But the differences of blood lead and blood ZPP between two genotypes were not statistically significant. 4. There were no differences of cross-sectional renal function indices (BUN, serum creatinine, uric acid and total protein) either by lead workers and non-lead workers or two genotypes. 5. In multiple regression analysis of ALAD genotype on BUN after controlling for possible confounders (sex, weight, job duration, smoking and drinking status), the mean of BUN in ALAD2 subjects was 0.629 ㎎/㎗ lower than ALAD1 subjects with a weak statistical significance (p=0.07). But in logistic analysis of ALAD genotype on median value of BUN revcaled that subjects of ALAD2 genotype were 32% less likely to have median value or more of BUN than subjects of ALAD1 with odd ratio of 0.618 (95% confidence interval 0.411-0.920). 6. In multiple regression analysis of ALAD genotype on serum creatinine after controlling for possible confounders (sex, weight, job duration, smoking and drinking status), the mean of serum creatinine in ALAD2 subjects was 0.0271 ㎎/㎗ lower than ALAD1 subjects with statistical significance (p=0.02). On the other hand, in logistic analysis of ALAD genotype on median value of serum creatinine revealed that subjects of ALAD2 genotype were 30% less likely to have median value or more of scrum creatinine than subjects of ALAD1 with odd ratio of 0.700 (95% confidence interval 0.442-1.080). With the above results, it was found that the variant allcle, ALAD2 appeared to modify the association of lead and renal function and ALAD2 genotype may be supportive for the protective effect of lead.

On the Sluicing with Covert Correlates

Sun-Woong Kim,Soo-Bong Kim 한국생성문법학회 2017 생성문법연구 Vol.27 No.3

Kim, Sun-Woong, Kim, Soo-Bong. 2017. On the Sluicing with Covert Correlates. Studies in Generative Grammar, 27-3, 631-647. This paper is an attempt to explain Chung s (2013) generalization not in terms of Case but in terms of phase. The sprouting type sluicing shows that pied piped PPs can be a sluice but not NPs. Regarding this contrast, Chung (2013) captures a generalization that prepositions cannot be stranded under sluicing when the antecedent clause does not contain an indefinite antecedent. An immediate question regarding this generalization is why? Another question, from a broader perspective, does which approach to sluicing better explain the data, PF-deletion or LF-copying. This paper shows that Chung s (2013) generalization regarding the preposition stranding and sprouting type sluicing can be derived from deeper derivational principles in terms of the non-rigid definition of phases. This paper eventually supports the view that the PF-deletion approaches to sluicing are better than LF-copying approaches. The solution is extended to explain the irreparable examples of left branch extraction (LBE) in English.
