본 논문은 지난 1월 '벤처기업 육성에 관한 특별조치법(이하, 벤처기업법)'이 한시법에서 상시법으로 변경되고, 이에 추가적으로 성과조건부주식(일명 이하 RSU: Restiricted Stock Unit) 도입 등의 내용이 담긴 일부개정법률이 국무회의를 통과하며 2024년 7월 시행을 예고하고 있는 시점에서, RSU가 당초 도입 취지에 맞게 스타트업과 벤처기업의 우수인력유치 위한 실효성을 담보 할수 있는지 여부와 이의 제고를 위해서는 어떠한 방안들이 추가 검토되어야 하는지에 대한 방안을 도출하는데 목적이 있다. 본 논문은 크게 세 가지의 연구내용을 분석하였다. 첫째, RSU가 어떻게 기존 다른 주식보상제도와는 다르게 스타트업과 벤처기업에 우수인력 유치가 가능하도록 도모하는지에 대한 분석이다. 둘째, 현재 도입예정인 RSU 법률안에 대해 주요법률적 쟁점을 넘어 스타트업과 벤처기업의 시장현장 관점에서 얼마나 실효성이 담보되어 있는지를 분석하는 것이다. 셋째, 현재 도입예정인 RSU 법률안이 스타트업과 벤처기업에게 우수한 인력유치라는 도입 취지를 제고하기 위해서는 어떠한 보완이 추가되어야 하는지에 대해 쟁점을 도출하고 이를 스타트업과 벤처생태계의 주요 관련 이해그룹의 전문가들을 대상으로 FGI를 실시하여 시장친화적인 RSU 세부도 입방안 기반을 제공하는 것이다. 본 논문은 도입예정인 RSU가 우수한 인력유치가 절실한 스타트업과 중소벤처기업에게 자본여력이 충분하지 못한 상황에서도 보유주식을 활용해 우수인력을 유치하도록 견인 할 수 있는 제도적 기반 마련 즉, 향후 예정되어 있는 RSU의 대통령 시행령 기반 마련에 일조할 것으로 기대한다. 이를 통해 본 논문은 RSU가 기존 주식보상제도들의 한계를 극복하는 대안으로 성장하며, 스타트업과 벤처생태계의 우수인력 유치수단으로 안착하는데 기여할 것으로 기대한다.

본 연구에서는, 기존의 악세스빌리티지표가 다양한 효과를 고려하지 못한다는 점에 착안하여, 새로운 악세스빌리티지표를 개발하였다. 노드의 중심성을 나타내는 중심도함수에 근거해, 네트워크 악세스빌리티지표(Netword Accessibility Index)와 철도이용자의 효용최적화의 관점으로부터 유틸리티 악세스빌리지표(Utility Accessibility Index)를 제안하였다. 그리고, 본 연구에서 제안한 지표가 종래의 지표보다 철도건설에 따른 편익치를 보다 정확하게 나타내는지를, 서울시지하철5호선과 오사카JR동서선의 개업효과를 계측함으로써 검증하였다. JR동서선의 경우, 중심지까지의 기존노선이 기설되어 있어 소요시간 단축효과보다 수송력증강과 철도네트워크의 확충에 의한 효과가 보다 크게 반영되었다. 또한, 위에서 산출한 편익치를 환수하기위한 기초데이타로 활용해, 고정자산세와 토지양도 소득세를 적용해 환원액을 산출하였다. 그리고, 이렇게 구한 환원액을 특정재원화시켜, 지하철5호선과 JR동서선의 사업주체에 보조해, 사업자의 채산성에 어떠한 영향을 미치는지, 신선건설비를 부담하는 해당 지자체의 비용부담을 어느정도 경감시킬 수 있는지를 정량적으로 밝혔다.

Through an examination and analysis of straight bills of lading and sea waybills in the context of English, U.S.A and Korean law, and relevant international conventions on maritime transport, the following results were obtained: Prior to the enactment of U.K.'s the Carriage of Goods by Sea Act in 1992, straight bills of lading had functional differences between countries. However, after the enactment of this law, negotiable bills of lading obtained the same legal status and functionality in both Korea and the United States, as well as in the UK. As for sea waybills, all three countries treated them with the same contractual and legal status. In other words, they serve as receipts for the transported goods and act as evidence of the maritime transportation contract. Nevertheless, they are non-negotiable, and the delivery of goods can be made to the consignee or their agent based on their identity. However, the transfer of ownership rights over the goods or acquisition of legal rights against the carrier cannot be achieved through the transfer or endorsement of Sea Waybills.

This study inquires into what effect the tax burden of investors, for typical taxes related to real estate investment; acquisition tax, comprehensive real estate holding tax, and transfer income tax, might have on the real estate investment behaviors; the purpose of long-term investment. These real estate investment behaviors have been analyzed to see how much they affect investment performance such as realized compound yield. This study model, which considers the fact that the choice of investment behavior for the degree of tax burden of investors may lead to different results in real estate investment, is expected to be an effective decision-making tool for investment.

The characters of Chamaecyparis obtusa community extended around the Mt. Gyeryoung in Geoje-cik were investigated for several ecological parameters and the results can be summarized as fellows. Chamaecyparis obtusa is prevailing in the plantation area, whereas Pinus densiflora and Quercus mongolica are prevailing in its outskirts. Plant biomass and net production which estimated from degree of green naturality and Miami's model were much higher in the plantation than those of the natural forest. However, the mean species diversity of plantation was lower than that of natural populations. In stratification of investigated areas, overstory tree layer was dominant in the zone of plantation and dominant layers in the natural forest were understory tree layer, shrub, and herb.

The subventricular zone (SVZ) in the brain contains neural stem cells (NSCs) that generate new neurons throughout one's lifetime. Many extracellular and intracellular factors that affect cell proliferation and neuronal differentiation of NSCs are already well-known. Recently, L-type calcium channels have been reported to regulate neural development and are present in NSCs, differentiating neuroblasts, and mature neurons in the SVZ. Nifedipine, a blocker of L-type calcium channels, has been long used as a therapeutic drug for hypertension. However, studies on the use of nifedipine to inhibit L-type calcium channels of NSCs are lacking. Herein, we treated NSCs cultured from mouse postnatal SVZ with nifedipine during neuronal differentiation. Nifedipine increased the number of Tuj1-positive neurons but did not significantly change the number of Olig2-positive oligodendrocytes. Nifedipine increased cell division during early differentiation, which was detected using the 5-ethynyl-2'-deoxyuridine incorporation assay and immunocytochemistry assessment by staining the cells with phosphorylated histone H3, a mitosis marker. Nifedipine increased the transcription of Dlx2, a neurogenic transcription factor, and the level of Mash1, a marker for early neurogenesis. In addition to nifedipine, verapamil, which is also an L-type calcium channel blocker, showed a slight increase in neurogenesis, but its statistical significance was very low. In contrast, pimozide, a T-type calcium channel blocker, did not affect neurogenesis, although T-type calcium channel genes Cav3.1, Cav3.2, and Cav3.3 were expressed. In summary, nifedipine might promote the neuronal fate of NSCs during early differentiation and calcium signaling through L-type calcium channels might be involved in neuronal differentiation, especially during the early stages of differentiation.

Rodent models have been used to study the anticarcinogenic properties of the soy isoflavones, particularly genistein, but there is little information regarding the pharmacokinetics of the absorption and excretion of genistein. In this study, rats were given a single oral dose of genistein (20 mg/kg body wt) or an equivalent dose as Myougjoonamul-kong and Myoungjoonamul soy sprouts. Concentrations of genistein were measured in plasma, urine and feces at intervals up to 48hr after dosing. Maximum peak of plasma genistein concentration is 8 hr after dosing, and its concentration is 13.2, 7.4mol/L in soy and soy sprout-treated rats, respectively. In pure genistein treated rats, maximum peak of plasma genistein concentration is 2hr after dosing (5.7 mol/L). The percentage of dose recovered in urine over 48hr was not different between groups ($21.2\%$ soy treated; $18.2\%$ soy sprout treated; $16.1\%$ pure genistein treated). There were no significant differences between groups in the recovery of genistein in feces ($19.5\%,\;7.5\%\;and\;15.7\%$ of doses, respectively). $6.9\%\;and\;6.07\%$ of the daidzein from the soy and soy sprout treated was recovered in the feces.
