4차 산업 시대를 맞이한 지금, 많은 나라에서 인공지능(AI) 역량을 지닌 인재양성을 위해 초등학교부터 고등학교까지 체계적이고 연속적인 소프트웨어(SW)교육을 제공하고 있다. 이에 반해 국내 현실은 연계성 있는 SW 교육이 학습자에게 제공되지 않아 SW 격차가 심화하고 양극화될 그것을 우려하는 목소리가 높다. 이러한 배경으로 본 연구는 대학의 SW 교육에서 발생하는 학습자 간의 차이를 초중등학교에서 SW·인공지능교육의 수업 결손이라는 관점에서 보고 연구를 시작하였다. 이공계열 신입생을 대상으로 1단계 SW 기초교육 전과 후로 나누어 '컴퓨팅사고(CT) 자기효능감', 'AI 자기효능감'으로 나누어 분석하였고, 그 결과 SW 경험이 미치는 영향은 유의미하다는 결과를 얻었다. 이 연구의 결과를 바탕으로 연계성 있는 SW 교육이 제도적으로 뒷받침되기 위한 다양한 논의가 활발히 이루어지기를 기대한다.

An earthquake of $M_L$ 5.8 hit the Gyeongju area on September 12, 2016. A sequence of foreshock-mainshock-aftershock of 588 events with equal to or greater than magnitude 1.5 occurred for six months in this area. Around ninety-nine percentage (98.8%) of the total energy was released intensively within a day, and about 80% of the total events took place within a month after the Gyeongju earthquake. The epicentral distribution of aftershocks of major events ($M_L$ 5.1, 5.8, 4.5, and 3.5) were elongated in the direction of $N30^{\circ}E$. They correlate well with the focal mechanism solution. These facts support the inference that the Gyeongju earthquakes occurred on a sub-parallel subsidiary fault of the Yangsan fault zone or on the linking damage zones between Deokcheon and Yangsan fault. During the last six years before the Gyeongju earthquake, there were few events within 10-km radius from the epicenter. This seismic gap area was filled with a sequence of the Gyeongju earthquakes. The b value for aftershock of the Gyeongju earthquakes is 1.09.

Purpose: The purpose of this study was to examine the effect of a discharge education program on maternal role confidence and parenting stress of mothers who delivered premature infants. The program provided them with information on childrearing and supportive educational nursing care. Method: This study was based on pretest-posttest nonequivalent nonsynchronized quasi-experimental design. The participants in this study were 30 mothers who delivered premature infants at a general hospital in G city. The instruments used in this study were Maternity Confidence Inventory, Parenting Stress Index(PSI). Results: The first hypothesis that the mothers in the experimental group would undergo changes in maternal role confidence after the intervention was accepted, as there was a statistically significant gap between the two groups(F=9.386, P=.000). The second hypothesis that mothers in the experimental group would undergo change in parenting stress after the intervention was accepted, as there was a statistically significant gap between the two groups(F=4.425, P=.380). Conclusion: The findings suggest that the Discharge Education Program was an efficient intervention method to boost the maternal confidence of mothers with premature infants and to decrease their parenting stress.

In this paper, sub-harmonically pumped single balanced resistive mixers are presented . Frequency bandwidth is selected for a Ku-band, which is 11.75-12.25GHz for RF, 5.375∼5.625 GHz for LO, and 1 GHz for IF signals. A rat-race hybrid is designed for the accomplishment of single balanced type. A low pass filter (LPF) with photonic band gap(PBG) structure is used for good conversion loss and unwanted harmonics suppression. Two types of mixers are suggested, which are one with no gate bias for no DC power consumption and the other with the IF amplifier for conversion gain. When a LO signal with the power of 6 dBm at 5.5 GHz is injected, a conversion loss of 12.17dB and a conversion gain of 7.83 dB are obtained for each mixer. For the both mixers , LO to RF isolation of 20 dB and LO to IF isolation of 60dB are obtained. With the RF power of -30dBm to -3dBm, the mixer shows linear characteristics region of IF. this mixer can be applied for Ku-band and other microwave communication systems.

Using a CFD (computational fluid dynamics) simulation tool, we have offered a design guideline of a slot-die head having a simple T-shaped cavity through an analysis of the fluid dynamics in terms of cavity pressure and outlet velocity, which affect the uniformity of coated thin films. We have visualized the fluid flow with a transparent slot-die head where poly(3,4-ethylenedioxythiophene):poly(4-styrenesulfonate) (PEDOT:PSS) is injected. We have shown that the fluid dynamics inside the slot-die head depends sensitively on the cavity depth, cavity length, land length, and channel gap (i.e., shim thickness). Of those, the channel gap is the most critical parameter that determines the uniformity of the pressure and velocity distributions. A pressure drop inside the cavity is shown to be reduced with decreasing shim thickness. To quantify it, we have also calculated the coefficient of variation (CV). In accordance with Hagen-Poiseuille's laws and electron-hydraulic analogy, the CV value is decreased with increasing cavity depth, cavity length, and land length.

There exists a popular belief that the elderly are more conservative than the younger people in acceptability of new technology. This study explores whether the generation gap in technology acceptance exists in the case of using telepresence robots, which project the presence and mobility of remote operator, for the universal purpose of social participation rather than for specific applications. Two groups of senior citizens and undergraduate students in their twenties personally experienced the telepresence robots operation and conducted a survey on how they perceived the social participation of a remote operator mediated by telepresence robot and to what extent the remote operator deserve equal rights to be treated as if one really exists in the local environment. The results show that the elderly have higher expectation on the role and functions of telepresence robots, and more favorable in principle for a remote operator to exercise equal rights by operating telepresence robot. It suggests that the stereotypes, the elderly lag behind younger generation in accepting new technology, is unlikely to fit into the telepresence robot market, for the elderly have more favor and support using telepresence robots as an universal avatar for social participation.

본 연구는 수도권과 비수도권 근로자의 임금격차와 인적자본 수준 사이의 관계를 분석하는 것을 목적으로 한다. 보다 구체적으로 수도권 근로자가 비수도권 근로자보다 더 높은 수준의 임금을 받는 이유가 수도권 근로자의 인적자본 수준이 비수도권 근로자의 인적자본 수준보다 더 높기 때문인지 아니면 동일한 인적자본 수준을 가졌음에도 불구하고 수도권 근로자에게 더 높은 보상이 제공되기 때문인지에 대해 살펴보는 것이다. 본 연구는 무조건 분위회귀 분해법을 이용하여 수도권과 비수도권 근로자의 임금격차와 인적자본 사이의 관계가 임금 분위에 따라 상이하게 나타는지를 확인하고자 하였다. 또한 전통적인 인적자본 지표인 교육년수 및 직무훈련과 함께 인지 및 상호적 숙련, 기술적 숙련, 육체적 숙련 등 직종 숙련 수준을 고려하였다. 분석 결과에 따르면, 성별, 정규직 여부, 기업 규모 등의 변수들이 통제된 상태에서 수도권과 비수도권 근로자의 임금격차의 상당 부분이 인적자본 변수들에 의해 설명되는 것으로 나타났다. 인적자본의 질적인 차이로 인한 임금격차를 의미하는 인적자본의 구성 효과가 모든 임금 분위에서 존재하는 것으로 나타났지만, 수도권과 비수도권 근로자의 임금격차 문제에서 보다 중요하게 작용하는 요인은 인적자본의 임금구조 효과인 것으로 나타났다. 직종 숙련을 포함한 다양한 인적자본 변수들 중에서도 특히 교육년수의 임금구조 효과가 수도권과 비수도권 근로자의 임금격차를 설명하는 데에 있어 핵심적인 요인인 것으로 나타났다. 본 연구는 중위임금 또는 평균임금 수준에 초점을 두고 있는 전통적인 분석방법에서 벗어나 수도권과 비수도권 근로자 사이의 임금격차가 임금 분위에 따라 상이한 양상을 나타낼 수 있음을 무조건 분위회귀 분해를 통하여 밝혔다는 점에서 연구의 의의가 있다.

Purpose - This pilot study explores the gap between venture capitalists and young business graduates in Pakistan. Though the young graduates remain enthusiastic about choosing entrepreneurship as a profession, their success is subject to financial constraints. Research design, data, methodology - We administered a Likert-scale based questionnaire to 200 business graduates from June to July 2012, and interviewed ten venture capitalists from Islamabad and Lahore-two highly business oriented cities of Pakistan-to collect the data. The survey participation was on a voluntary basis without any financial sponsorship. Findings- There is a communication gap between the two parties (venture capitalists and business graduates), and a lack of trust in the entrepreneurial education and training offered in the educational institutions in Pakistan. The study, however, reveals the leading role of the Government in reducing this gap through certain measures. Conclusions - Some measures that can reduce the gap between venture capitalists and young graduates are: association of business schools with industry; financial institutions'initiatives to financially support the small and medium level projects of the economics and business students during their studies; establishment of placement bureaus in the business schools; and organization of regular open houses in the universities.
