본 연구는 제주 올레 트레킹코스의 개발이 인근 토지의 지가상승에 미친 영향을 FGLS(Feasiable Generalized Least Square)를 사용하여 분석하였다. 분석자료로는 제주올레 7코스 주변의 2010년 개별공시지가자료를 사용하였는데, GIS프로그램을 이용하여 제주올레7코스로부터 각 필지까지의 거리를 측정하여 설명변수로 사용하였고, 그 외 다양한 토지가격영향요인들을 설명변수로서 고려하였다. 종속변수로는 2002년과 2010년 사이 토지가격변화율을 사용하였다. 기존 연구들이 고속도로, 지하철 등 교통시설의 개발이 주변 토지가격에 미친 영향을 분석한 반면, 본 연구는 국내에서는 처음으로 트레킹코스의 개발이 주변 토지가격에 미친 영향을 분석하였다는 데에 의의가 있다. 본 연구의 분석결과 올레7코스의 개발은 인근의 토지시장에 유의한 영향을 미치는 것으로 나타났다. 구체적으로는 올레7코스로부터 1미터 멀어질수록 토지가격 상승률이 0.03% 하락하는 것으로 나타났다. 이러한 결과는, 고속도로나 지하철과 같은 교통시설의 건설만이 부동산시장에 영향을 주는 것이 아니라, 제주올레와 같은 트레킹코스의 개발도 인근의 부동산시장에 영향을 줄 수 있다는 것을 보여준다.

세계 주요 도시는 자동차로 인한 교통 정체, 에너지 과소비, 환경오염 등을 해결하는 대안으로 대중교통을 주목하고 있다. 아울러 대중교통에 대한 쉬운 접근성이 그 이용을 높인다는 점에서 여러 연구는 대중교통에 대한 접근성을 개선하는 것이 중요함을 강조하였다. 이러한 대중교통은 부동산 가치 평가와 투자 결정에도 중요한 변수로 작용한다. 이 연구는 대중교통 접근성에 대한 기존 접근방법을 비판적으로 검토한 후 수요-공급 기반 접근성 기법으로 서울시 지하철역에 대한 접근성을 측정한다. 그 다음 그 영향을 용도별, 분위별 토지가격을 통해 분석하였다. 다층헤도닉모형으로 분석한 결과, 첫째, 지하철에 대한 수요와 공급을 모두 고려한 접근성은 주거용과 비주거용 토지가격에 모두 긍정적 영향을 주었다. 영향은 비주거용보다 주거용에 보다 강하게 나타났다. 둘째, 총 세 개의 함수로 측정한 접근성 가운데 Exponential 함수에 의한 접근성은 주거용 토지가격에 가장 적합했으며, 비주거용 토지가격에는 Power 함수로 측정한 접근성이 가장 설명력이 높았다. 셋째, 토지 가격 분위별 영향을 보면, 주거용과 비주거용 토지가격 모두 가장 비싼 분위에 가장 큰 영향을 준 것으로 나타났다. 아울러 분위별 가격에서도 모형적합도 측면에서 주거용은 Exponential 함수로 측정한 접근성, 비주거용은 Power 함수로 측정한 접근성이 상대적으로 적합한 것으로 나타났다. 이러한 연구 결과는 공공투자가 인근지역에 미치는 영향을 이해할 뿐만 아니라 부동산 가치평가, 대중교통 서비스로 인한 우발이익의 회수 방안 모색, 대중교통 투자로 인한 주거비 상승 대책 마련에 활용할 수 있을 것이다.

Objective: Nanog homeobox (NANOG) is a core transcription factor that contributes to pluripotency along with octamer binding transcription factor-4 (OCT4) and sex determining region-Y box-2 (SOX2). It is an epiblast lineage marker in mammalian pre-implantation embryos and exhibits a species-specific expression pattern. Therefore, it is important to understand the lineage of NANOG, the trophectoderm, and the primitive endoderm in the pig embryo. Methods: A loss- and gain-of-function analysis was done to determine the role of NANOG in lineage specification in parthenogenetic porcine blastocysts. We analyzed the relationship between NANOG and pluripotent core transcription factors and other lineage makers. Results: In NANOG-null late blastocysts, OCT4-, SOX2-, and SOX17-positive cells were decreased, whereas GATA binding protein 6 (GATA6)-positive cells were increased. Quantitative real-time polymerase chain reaction revealed that the expression of SOX2 was decreased in NANOG-null blastocysts, whereas that of primitive endoderm makers, except SOX17, was increased. In NANOG-overexpressing blastocysts, caudal type homeobox 2 (CDX2-), SOX17-, and GATA6-positive cells were decreased. The results indicated that the expression of primitive endoderm markers and trophectoderm-related genes was decreased. Conclusion: Taken together, the results demonstrate that NANOG is involved in the epiblast and primitive endoderm differentiation and is essential for maintaining pluripotency within the epiblast.

Purpose - Many retail stores tend to use scarcity-laden message in order to influence consumers, where scarcity refers to insufficiency of product supply or time of availability. For example, inside stores, the displayed products are often accompanied by scarcity message such as 'exclusive offer, limited time only.' According to past research, scarcity has a positive effect on product evaluation, since scarcity can acts as a signal of consumer demand, and thus product quality. Prior studies argue that consumers face a scarce product, they logically infer that other consumers buying the product in large numbers cause the scarcity. We propose that scarcity can be interpreted as a sales tactic artificially created by retail stores in order to increase sales of product. Research design, data, and methodology - We use a persuasion knowledge perspective framework to develop our hypotheses. In the present research, we show that product curation type is a key variable that moderates consumer response to scarcity, and thus the scarcity effect on product evaluation. Results - In this research, we showed when scarcity-laden message was used inside the store using consumer-centric curation message, scarcity had a positive effect on product evaluation. In contrast, when scarcity-laden message was used inside the store using marketer-centric curation message, the positive of scarcity message on product evaluation was diluted. Conclusions - Our study makes two important contributions to the literature on consumer response to scarcity. First, we identify a variable - namely, product curation type - that determines when either 'scarcity = good' or 'scarcity = marketing tactic' interpretation is likely to be dominant. Second, we cite persuasion knowledge perspective to explain the moderating function of product curation type in a retail store-related scarcity context. This research is relevant to practitioners, such as brand manager, retail environment manager, and advertising agencies, for the effective use for the scarcity-laden message in retail. The proposed moderator can operate in many real-life situations in retail where consumers are exposed to scarcity. And curation message related to scarcity has been facilitated by the inner-retail activities. These factors of the marketplace indicate that the boundary conditions of scarcity can have a significant effect on real-life consumer judgment.

Objective: The present study was conducted to investigate the effects of a lipid-coated zinc oxide (ZnO) supplement Shield Zn (SZ) at the sub-pharmacological concentration on intestinal morphology and gene expression in weanling pigs, with an aim to gain insights into the mechanism of actions for SZ. Methods: Forty 22-day-old weanling pigs were fed a nursery diet supplemented with 100 or 2,500 mg Zn/kg with uncoated ZnO (negative control [NC] or positive control [PC], respectively), 100, 200, or 400 mg Zn/kg with SZ for 14 days and their intestinal tissues were taken for histological and molecular biological examinations. The villus height (VH) and crypt depth (CD) of the intestinal mucosa were measured microscopically following preparation of the tissue specimen; expression of the genes associated with growth and immune function was determined using the real-time quantitative polymerase chain reaction. Results: There was no difference in daily gain, gain:feed, and diarrhea score between the SZ group and either of NC and PC. The VH and VH:CD ratio were less for the SZ group vs NC in the jejunum and duodenum, respectively (p<0.05). The jejunal mucosal mRNA levels of insulin-like growth factor (IGF-I) and interleukin (IL)-10 regressed and tended to regress (p = 0.053) on the SZ concentration with a positive coefficient, respectively, whereas the IL-6 mRNA level regressed on the SZ concentration with a negative coefficient. The mRNA levels of IGF-I, zonula occludens protein-1, tumor necrosis $factor-{\alpha}$, IL-6, and IL-10 did not differ between the SZ group and either of NC and PC; the occludin and transforming growth $factor-{\beta}1$ mRNA levels were lower for the SZ group than for PC. Conclusion: The present results are interpreted to suggest that dietary ZnO provided by SZ may play a role in intestinal mucosal growth and immune function by modulating the expression of IGF-I, IL-6, and IL-10 genes.

This study estimates the random utility function of fluid milk using 1,165 survey responses in Laos. It finds that both products' attributes and individual characteristics affect consumers' preference for the milk and the hypothetical brand of Laos-Korea has a potential compared to four real dairy products. Results also show that calories have a positive relationship with consumer's preference while the price and fat content have a negative one. The decision for choosing each brand is significantly affected by individual characteristics such as gender, age, whether or not respondents live with their children, the level of education, income, the frequency of purchasing milk per week, and the region where they live. The preference for five brands appears in the order of Foremost, Nabong, Thai-Danish, Meiji, and Lao-Korea, and probabilities of purchasing each brand at the mean level are 30.9%, 17.48%, 21.48%, 15.0% and 10.39%, respectively. Nabong that was Lao national milk brand still has a significant market power even though it was closed in 2008. The policies to promote milk industry by implementing its national milk brand again would be more effective if it focuses on the young generation, female consumers, families with children, quality of dairy products, and Vientiane capital areas.

Let A(p) be the class of functions $f\;:\;z^p\;+\;\sum\limits_{j=1}^{\infty}a_jz^{p+j}$ analytic in the open unit disc E. Let, for any integer n > -p, $f_{n+p-1}(z)\;=\;z^p+\sum\limits_{j=1}^{\infty}(p+j)^{n+p-1}z^{p+j}$. We define $f_{n+p-1}^{(-1)}(z)$ by using convolution * as $f_{n+p-1}\;*\;f_{n+p-1}^{-1}=\frac{z^p}{(1-z)^{n+p}$. A function p, analytic in E with p(0) = 1, is in the class $P_k(\rho)$ if ${\int}_0^{2\pi}\|\frac{Re\;p(z)-\rho}{p-\rho}\|\;d\theta\;\leq\;k{\pi}$, where $z=re^{i\theta}$, $k\;\geq\;2$ and $0\;{\leq}\;\rho\;{\leq}\;p$. We use the class $P_k(\rho)$ to introduce a new class of multivalent analytic functions and define an integral operator $L_{n+p-1}(f)\;\;=\;f_{n+p-1}^{-1}\;*\;f$ for f(z) belonging to this class. We derive some interesting properties of this generalized integral operator which include inclusion results and radius problems.

The p38 mitogen-activated protein kinase (MAPK) is involved in various processes, including stress responses, development, and differentiation. However, little information on p38 MAPK in insects is available. In this study, a p38 MAPK gene, $Accp38b$, was isolated from $Apis$ $cerana$ $cerana$ and characterized. The quantitative real-time PCR (Q-PCR) analysis revealed that $Accp38b$ was induced by multiple stressors. Notably, the expression of $Accp38b$ was relatively higher in the pupae phase than in other developmental phases. During the pupae phase, Accp38b expression was higher in the thorax than in the head and abdomen and higher in the fat body than in the muscle and midgut. Immunohistochemisty showed significant positive staining of Accp38b in sections from the brain, eyes, fat body, and midgut of $A.$ $cerana$ $cerana$. These results suggest that Accp38b may play a crucial role in stress responses and have multiple aspects function during development.

Structural changes of the endosperm of Panax ginseng C.A. Meyer from fertilization to germination were investigated by light microscope. The endosperm of the ginseng seed is cellular type. Since endosperm cells adjacent embryo continuously breakdown and disappear with the elongation of embryo, the real of endosperm is gradually decreased. As the anatropous ovules of immature seed with green seed coat developes more and more, ovary cells adjacent ovary cavity become abundant by the periclinal division, their size is decreased, hypotrophy of cell wall discern, and they are gradually differentiated in seed coat. Though embryo responds strongly to basic dye at the stage of completion of endosperm formation, tissue of endosperm responds to acidic dye positively Cell wall of embryo and endosperm are composed of primary cell wall not lignified. Endosperm cells adjacent embryo begin to breakdown in the endosperm tissue of indehiscent seed before the beginning of the after-ripening. Dehiscent seed of which seed coat is opened through after-ripening represent the form as a seedling in the result of embryo developments with the formation of organs; radicle, cotyledon, plumule. Umbilifom layer represents strong positive response to the toluidine blue and the basic function. Umbiliform layer that endosperm cells breakdown and disappear is observed clearly at the periphery of the embryo cotylemon, while slightly at the periphery of the radicle.

Electrical gate and drain characteristics of double heterostructure InAlAs/InGaAs pseudomorphic HEMTs have been investigated under sub-bandgap photonic excitation ($hv). Drain $(V_{DS})-,{\;}gate($V_{DS})-$, and optical power($P_{opt}$)-dependent variation of the abnormal gate leakage current and associated physical mechanisms in the PHEMTs have been characterized. Peak gate voltage ($V_{GS,P}$) and the onset voltage for the impact ionization ($V_{GS.II}$) have been extracted and empirical model for their dependence on the $V_{DS}$ and $P_{opt} have been proposed. Anomalous gate and drain current, both under dark and under sub-bandgap photonic excitation, have been modeled as a parallel connection of high performance PHEMT with a poor satellite FET as a parasitic channel. Sub-bandgap photonic characterization, as a function of the optical power with $h\nu=0.799eV$, has been comparatively combined with those under dark condition for characterizing the bell-shaped negative humps in the gate current and subthreshold drain leakage under a large drain bias.
