기술 기반 신생기업들은 창업 초기부터 세계화를 추구함으로써 경쟁력을 확보하려는 BGF전략을 추구하는 현상은 기존 국제화 이론으로는 설명하기 어려운 현상으로 태생적 글로벌 기업(BGF 또는 BGV)에 대한 새로운 접근법이 적용되고 있다. 그러나 BGF에 대한 대부분의 연구는 세계화 전략의 선행 요소)에 초점을 맞추고 있어 기업 재무성과에 어떤 영향을 미치는가에 대한 연구는 적으며 기존의 연구 결과의 일관성도 없는 상황이다. 이러한 차이는 BGF에 대한 정의의 문제와 연구 방법과 연구 대상에 의한 결과이며 특히 기업의 재무적 성과에 대한 측정의 타당성 부족에 기인한 것이다. 본 연구는 기존 연구의 한계를 극복하고 신속한 세계화 전략이 BGF의 성과(매출량, 투자수익률, 직원당 순이익, 매출증가율, 종업원당 순이익 증가율)에 어떤 영향을 미치는지 이해하기 위해 KIS-Value의 2차 자료를 활용하여 연구를 시도 하였다. 특히, BGF에 대한 정의를 기업이 설립 후 5년 내에 수출 집중도가 25%, 50%, 75%에 따른 수준별 구분에 따라 분석을 시도하였다. 본 연구의 결과는 첫째, 신속한 국제화 전략은 장·단기적으로 매출 효과는 있는 것으로 검증되었고 특히, 단기적인 효과가 장기적인 효과에 비하여 크게 나타났다. 그러나 BGF의 투자 수익률(ROI)에 대한 영향은 BGF수준이 엄격할수록 ROI에 대한 단기적인 영향은 있지만 장기적인 영향은 사라지는 것으로 나타났다. 셋째, 매출 성장률 성과는 BGF수준에 따라 단기적 효과가 있으나 ROI와 같이 장기적인 효과는 나타나지 않는다. 반면에 순이익 증가율은 BGF전략이 장기적으로는 부정적인(-) 효과가 있는 것으로 나타났다. 특히, 기업의 BGF 수준이 높을수록 순이익 증가율에 미치는 부정적인 영향은 더 크게 나타났다.

Rice cultivation in paddy field affects the global balance of methane ($CH_4$) as a key greenhouse gas. To evaluate a potential use of by-product gypsum fertilizer (BGF) in reducing $CH_4$ emission from paddy soil, $CH_4$ fluxes from a paddy soil applied with BGF different levels (0, 2, 4 and $8Mg\;ha^{-1}$) were investigated by closed-chamber method during rice cultivation period. $CH_4$ flux significantly decreased (p<0.05) with increasing level of BGF application. $8Mg\;ha^{-1}$ of BGF addition in soil reduced $CH_4$ flux by 60.6% compared to control. Decreased soil redox potential (Eh) resulted in increasing $CH_4$ emission through a $CO_2$ reduction reaction. The concentrations of dissolved calcium (Ca) and sulfate ion (${SO_4}^{2-}$) in soil pore water were significantly increased as the application rate of BGF increased and showed negatively correlations with $CH_4$ flux. Decreased $CH_4$ flux with BGF application implied that ${SO_4}^{2-}$ ion led to decreases in electron availability for methanogen and precipitation reaction of Ca ion with inorganic carbon including carbonate and bicarbonate as a source of $CH_4$ formation under anoxic condition. BGF application also increased rice grain yield by 16% at $8Mg\;ha^{-1}$ of BGF addition. Therefore, our results suggest that BGF application can be a good soil management practice to reduce $CH_4$ emission from paddy soil and to increase rice yield.

This study aimed to evaluate the ability to reduce flood damage caused by abnormal rainfall events due to climate change by utilizing a blue-green roof (BGF), a type of rooftop greening technology. For two buildings with the same roof area, a BGF was installed in the experimental group, a general roof was configured in the control group, and rainfall runoff was compared. A total of 10 rainfall events were tested and analyzed by classifying them into three rainfall classes (less than 10 mm, less than 100 mm, and more than 100 mm). There was a reduction of 100% in the case of 10 mm or less of rainfall, 84. 7% in the case of 100 mm or less, and 39.8% in the case of 100 mm or more. Although this study showed that a BGF was effective in reducing rainfall runoff, additional experiments and analyses of various factors affecting rainfall runoff reduction are needed to generalize the results of the study. This research methodology may be used to develop a method for evaluating the resilience of a BGF to flood damage due to climate change.

Many of the 𝛽-glucans are known to have antihypertensive activities, but, except for angiotensin-converting enzyme II inhibition, the underlying mechanisms remain unclear. Corin is an atrial natriuretic peptide (ANP)-converting enzyme. Activated corin cleaves pro-ANP to ANP, which regulates water-sodium balance and lowers blood pressure. Here, we reported a novel antihypertensive mechanism of 𝛽-glucans, involved with corin and ANP in mice. We showed that multiple oral administrations of 𝛽-glucan induced the expression of corin and ANP, and also increased natriuresis in mice. Microarray analysis showed that corin gene expression was only upregulated in mice liver by multiple, not single, oral administrations of the 𝛽-glucan fraction of Phellinus baumii (BGF). Corin was induced in liver and kidney tissues by the 𝛽-glucans from zymosan and barley, as well as by BGF. In addition to P. baumii, 𝛽-glucans from two other mushrooms, Phellinus linteus and Ganoderma lucidum, also induced corin mRNA expression in mouse liver. ELISA immunoassays showed that ANP production was increased in liver tissue by all the 𝛽-glucans tested, but not in the heart and kidney. Urinary sodium excretion was significantly increased by treatment with 𝛽-glucans in the order of BGF, zymosan, and barley, both in 1% normal and 10% high-sodium diets. In conclusion, we found that the oral administration of 𝛽-glucans could induce corin expression, ANP production, and sodium excretion in mice. Our findings will be helpful for investigations of 𝛽-glucans in corin and ANP-related fields, including blood pressure, salt-water balance, and circulation.

The purpose of this study was to evaluate the shear bond strength of three light-cured glass ionomer cements to blood contaminated bovine dentin. The materials used in this study were Fuji II LC, Dyract and Variglass VLC. The dentin conditioners were 10% polyacrylic acid, 10% maleic acid and 10% phosphoric acid. 180 lower anterior bovine teeth were selected in this study. The teeth were embedded in acrylic resin and were grounded with 320 to 600 grit silicon carbide paper to create a flat dentin surface. The teeth were divided into SIX groups. The experimental procedures in six groups were as follows; Group l(GF) : Samples bonded to dentin surface with Fuji II LC after 10% polyacrylic acid treatment. Group 2(BGF) : Samples bonded to dentin surface with Fuji II LC after 10% polyacrylic acid treatment and blood contamination. Group 3(MD) : Samples bonded to dentin surface with Dyract after 10% maleic acid treatment. Group 4(BMD) : Samples bonded to dentin surface with Dyract after 10% maleic acid treatment and blood contamination. Group 5(PV) : Samples bonded to dentin surface with Variglass VLC after 10% phosphoric acid treatment. Group 6(BPV) : Samples bonded-to dentin surface with Variglass VLC after 10% phosphoric acid treatment and blood contamination. Group 1,3 and 5 were classified into the control groups, while group 2,4 and 6 were classified into the experimental groups. Each group contained 30 samples. After 24 hours water storage at $37^{\circ}C$, all smples were subjected to a shear load to fracture at a cross head speed of 1.0 mm/min with Instron universal testing machine(No. 4467). Debonded surfaces were observed under Scanning Electron Microscope(Hitachi S-2300) at 20kvp. The data were evaluated statistically at the 95% confidence level with Student's t-test. The following results obtained; 1. Shear bond strengths were higher in the control groups(1,3,5 group) than in the experimental groups(2,4,6 group). 2. The shear bond strength of group 5(PV) was the highest in the control groups, and the group 5 was significantly higher than the group l(GF) on the shear bond strength. 3. The group 4(BMD) was the highest on the shear bond strength, and the group 2(BGF) was the lowest in the experimental groups. The group 4(BMD) and 6(BPV) showed a significant difference with the group 2 on the shear bond strength. 4. All the groups showed an adhesive-cohesive failure. except the group 2(BGF) showing adhesive failure.
