본 논문의 목적은 첫째, 자본자유화로 인해 통화공급 구조가 이미 균형에서 이탈하여 심각한 수준의 불균형 상해에 있다는 점을 실증적으로 입증하고자 한다. 둘째, 자본유입에 따른 정책조정 비용을 감안한 통화정책 모형을 통해 주장에 대한 이론적 근거를 제시하고, 정책 조절에 수반되는 손실비용(損失費用)과 Mundell의 $\ulcorner$할당 문제(割當 問題)$\lrcorner$를 다시 조명해 보고자 한다. 세째, 자본유입에 따르는 문제점들을 해결할 수 있는 정책방안들을 Modigliani ar Miller의 명제(命題)에 입각한 새로운 각도에서 합리적 인 증시정책을 모색해 보고자 한다. 분석의 이론적 틀로서는 자본유입에 따라 수반되는 불확실성하의 정책조절 비용을 감안한 손실비용 최소화(loss cost minimization)를 통해, 통화 당국자는 총통화량을 정책적으로 내정된 목표값에 수렴시킨다고 가정하였다. 다른 한편, 자본유입에 따르는 문제점들을 통화시장에만 제한시키는 부분적(部分的) 균형분석(均衡分析) 대신, 이를 증권시장으로 직접 연계시켜 두 시장으로 확장된 틀을 활용하였다. 본 논문의 연구방법은 다음 두가지 측면의 접근식을 따랐다. 첫째, 자본자유화정책의 특성을 살펴보기 위해, 자본자유화 시점을 기준으로 삼아 과거 자본통제 시대의 $\ulcorner$사후적(事後的)인 중화정책(中和政策)$\lrcorner$에 의존하는 $\ulcorner$소극적(消極的)인 증권정책(證券政策)$\lrcorner$과 자본자유화시대의 $\ulcorner$사전적(事前的)인 상살정책(相殺政策)$\lrcorner$에 의한 $\ulcorner$거시적(巨視的)인 증권정책(證券政策)$\lrcorner$을 통해 고찰하는 비교분석론에 입각한 접근식을 택했다. 둘째, 외국자본의 유입동기(流入動機)를 문제해결의 시발점으로 삼아 이를 새로운 개방정책과 직결시켜 문제해결의 실마리를 풀어 보려는 선험적(先驗的) 접근식(接近式)을 택했다.

Background: It is essential to investigate the functionality of the newly developed knobble shoe. Purpose: The purpose was to explore how the body shape and balance change when wearing knobble shoes. Methods: Nine subjects wearing knobble shoes after walking for a month were analyzed. Results: For knobble shoes, we created various small air pockets in the insole to stimulate the soles of the feet to induce body changes. In particular, it was to promote the arch part of the foot by making a large lump inside and outside the center of the foot's arch. After wearing knobble shoes and using them for 30 days, the average blood sugar decreased by 31.1 mg. The lowering range was 5 to 120 mg. In one patient, the result of the hemoglobin test decreased by 7.5% to 6.5%. In the shoulder tapping test for a body balance test, seven subjects leaned to the right in a barefoot state, and two people to the left. However, after wearing shoes, all of them maintained equilibrium. knobble shoes fit, and balance was all stable. There were two subjects with a short left and four subjects with a short right. Conclusions: Blood sugar decreased after wearing the knobble shoes. The deformed shape of the body was restored to its original state by the knobble supporting the foot arch area. The balance of the sole directly affects the overall posture.

This study constructs a bayesian neoclassical DSGE model that applies oil usage. The model includes technology shocks, oil price shocks, and shocks to energy policies as exogenous driving forces. First, this study aims to analyze the roles of these exogenous shocks in the Korean business cycle. Second, this study examines the effects of long-term changes in the energy consumption structure, including the reduction in oil use as a share of energy consumption and improvement in oil efficiency. In the case of oil price shocks, results show that these shocks exert recessionary pressure on the economy in line with those obtained in the previous literature. On the other hand, shocks to energy policies, which reduce oil consumption per capital, result in opposite consequences to oil price shocks, decreasing oil consumption. Also, counterfactual exercises show that long-term changes in the energy consumption structure would mitigate the contractionary effects of oil price shocks.

The purpose of this study was to test the mediating effect of WLB on the relationship between the nursing practice environment and turnover intention of nurses. Data were collected from October 5 to October 30, 2020 for 144 nurses for more than 6 months at three general hospitals located in A-do. Data analyzed using the SPSS/WIN 23.0 program by t-test, ANOVA, Pearson's correlation coefficient, and regression analysis. As a result of the study, WLB was partial mediating role in the relationship between the nursing practice environment and turnover intention. Therefore, in order to reduce the turnover rate of nurses, it is necessary to develop and apply programs along with organizational human resource management strategies to positively improve the nursing practice environment of nurses and to promoting WLB. Based on the results of this study, we intend to provide basic data to reduce the turnover rate of nurses by positively recognizing the nursing practice environment of nurses and improving WLB.

Amidst the ongoing instability and military tensions between North and South Korea, it is essential for us to comprehend and assess North Korea's military capabilities, while preparing for potential contingencies through military reinforcement. However, to conduct a comprehensive analysis of the military balance on the Korean Peninsula, it is imperative to move beyond simplistic quantitative comparisons of combat capabilities and embrace a broader perspective, which includes qualitative comparisons of military strength, operational capabilities, and a nation's ability to wage war. To address this need, this study employs the method of "Net Assessment" to evaluate the relative combat power of South and North Korean conventional naval forces, with a particular focus on surface combatants. This evaluation involves both quantitative and qualitative comparisons of military assets (personnel and equipment) and intangible factors (naval strategies, geography, etc.). By conducting a holistic assessment, the research aims to identify and analyze strategic asymmetries that may exist between the two navies.

In Korea, various environmentally harmful subsidies are granted in agriculture, fishery, energy, electricity, transportation, steel and shipbuilding industry. Examples include tax-exempt fuel for agriculture & fishery, VAT- exemption for briquette & anthracite, temporary subsidy for fuel, production stabilizing subsidy for coal mining, subsidy for briquette. Korea's yearly total subsidy in energy area is about 5,291 billion won, among them is 4,870 billion won. To reduce air pollutants and to mitigate climate change, Korea has to review the phase-out of environmentally harmful subsidies and the phase-in of environment-friendly subsidy. The reduction or removal of environmentally harmful subsidies will enhance economic efficiency and bring about environmental benefits. Economic efficiency means less use of inputs, which reduces environmental cost and improves social benefits. This paper applies the Shoven and Whalley's model to the Korean economy and analyzes the general equilibrium incidence effects of reforming environmentally harmful subsidies in the energy and electricity in Korea. We consider several counterfactual scenarios in which current environmentally harmful subsidies are reduced or abolished, compare them with the reference case in the economy, and evaluated the change in efficiency costs and distributional incidence of tax reforms related to subsidies.

우리나라에서는 그 동안 유상증자(有償增資)시 주주배정(株主配定)(right offer)방식에 의하고 기업공개시의 발행가격도 일률적으로 산정(算定)되어 증권인수(證券引受)에 따른 인수기관(引受機關)(underwriter)의 역할이 제한되어 왔으나 앞으로는 증권발행방식이 다양화되어 발행가격의 결정을 포함한 인수기관의 역할이 강조될 것이다. 대부분 총액인수(總額引受)(firm commitment underwriting)방식을 택하는 미국자본시장에서 인수기관을 선정하고 발행조건들을 결정하는 방법에는 투자은행과의 협의(協議)(negotiation)에 의하는 방식과 비공개경쟁입찰(非公開競爭入札)(sealed bidding)에 의하는 방식이 있는데 많은 기업들은 상대적으로 비용이 많이 드는 협의발행을 선택한다. 본 연구에서는 이에 대한 가설들을 뉴욕증권거래소나 아메리칸증권거래소에서 거래되는 공익기업의 신주발행자료를 통해 실증 검정했다. 인수 스프레드(underwriting spread)는 발행금액에 관계없이 협의발행(協議發行)이 경쟁발행(競爭發行)보다 평균적으로 1.16% 높았으며 발행비용(發行費用)도 협의발행이 유의적인 수준에서 0.341% 정도 높았다. 비대칭정보하에서 신호균형(信號均衡)(signaling equilibrium)으로 설명할 수 없지만 협의발행에 의한 통합균형(統合均衡)(pooling equilibrium)의 가능성은 배제하지 못했다. 주식발행 발표일(發表日)(announcement date)을 전후해 인수방식에 따른 주가변동의 차이를 분석한 결과 대리인가설(代理人假說)은 부분적으로 지지했다. 발행일(發行日)(offering date)을 전후한 주가변동에 의하면 인수기관의 사전매각노력(事前賣却努力)이 협의발행하에서 더 높았으나 발행일 직후의 주가회복은 보이지 않아 인수방식에 따른 가격안정화(價格安定化) 노력의 차이는 없었다. 발행기업들간의 주가차별화의 정도를 분석한 결과 협의발행에서 인회활동(認淮活動) (certification effects)을 더 잘 할 수 있다는 사실을 지지하지 못했다.

In this paper, we conduct an objective performance analysis of the crosstalk cancellation scheme studied in [11]. While the conventional scheme is only applicable to a listener on the optimal listenable region (sweetspot), the space skew/crosstalk cancellation (SS/CC) scheme in [11] can mitigate crosstalk regardless of the listener's position by using listener position tracking (LPT) system. The SS/CC scheme is composed of two parts: LPT-based SS and CC parts. In this paper, the SS/CC scheme is evaluated by some criteria such as follows: condition number, and the balance characteristic, its root mean square error, and running average.

This paper presents a new algorithm about motion adjustment for dynamic balance. It adjusts an unbalanced motion to an balanced motion while preserving the nuance of original motion. We solve dynamic balancing problem using the zero moment point (ZMP) which is often used for controlling the balance of biped robot. Our algorithm is consists of four steps. First, it fits joint angle data to spline curves for reducing noise. Second, the algorithm analyzes the ZMP trajectory so that it can detects the dynamically-unbalanced duration. Third, the algorithm project the ZMP trajectory into the supporting area if the trajectory deviates from the area. Finally, the algorithm produces the balanced motion that satisfies the new ZMP trajectory. In this step, the constrained optimization method is used so that the new motion keeps the original motion characteristics as much as possible. We make several experiments in order to prove that our algorithm is useful to add physical realism to a kinematically edited motion.

It is well known that the current wireless sensor networks addressing methods do not work efficiently in networks more than a few hundred nodes. A standard protocol in ZigBee-Standard feature in ZigBee 2007 gives balanced tree based address assignment method with distributed manner. However, it was limited to cover less than hundreds of sensor nodes due to the wasteful use of available address space, because composed sensor networks usually make an unbalanced tree topology in the real deployment. In this paper, we proposed the hierarchical cluster tree based address assignment method to support large and scalable networks. This method provides unique address for each node with distributed manner and supports hierarchical cluster tree on-demand. Simulation results show that the proposed method reduces orphan nodes due to the address exhaustion and supports larger network with limited address space compared with the ZigBee distributed address assignment method defined in ZigBee-Standard feature in ZigBee 2007.
