This study examined discourses on “wise-mother and good-wife” in the 1920s - 1930s by analyzing the magazine “Shinyeosung.” This study found the following: 1 “Wise-mother and good-wife” was the ideal type for the “new women” during the colonial period. Hut the role of a mother was far more important than that of a wife. 2. The dominant discourse at the time was that the “genuine” new woman was defined by her motherhood, and she could not have a job because raising children was the most Important task for her. Hut in fact, new women wanted to be a wife through free love and marriage. They wished to be a good-wife in the “new (modern) family” for their loving husbands. 3. The Ideas of “wise-mother” and “good-wife” arose from disparate backgrounds. A woman had to nurture her maternal aptitudes; but had to suppress her passion for free love and marriage. Although she had to learn Western methods of bringing up children instead of the traditional one, she was expected to practice traditional virtues of a wife, not Western attitudes. The role of a mother was decided by experts, but that of a wife was decided by husbands. The function of a good-wife was merely a clever handling of her husband, whereas the function of a mother was considered to require professional knowledge. 4. New women could differentiate themselves from “old women” through the roles of wise-mother and good-wife; nonetheless, those roles were forced by society. They did not have any other viable choices.

In the automatic non-invasive blood pressure measurement device, the oscillometric method iswidely used. In the oscillometric method, the step-wise deflation has the advantage of the robustness for the motion artifacts than the linear deflation method. But it has the disadvantage of its longer measurement time because we need to detect two or more pulses in a certain cuff pressure step. In this study, we suggest the modified step-wise deflation method to overcome this limitation while maintaining the general concept of step-wise deflation. Using one valid pulse in each step and the deflating valve control during the diastolic period, the measurement time could be reduced. In order to verify the accuracy of the proposed algorithm, we compared the blood pressure values from the suggested method and the blood pressure values from the conventional auscultation method. The mean and standard deviation were -0.50${\pm}$5.3mmHg and 2.08${\pm}$4.75mmHg, for systolic and diastolic blood pressure respectively. The measurement time can be reduced up to the half of conventional step-wise deflation method.

단계별로 얻어진 $I{\times}J$ 이차원 범주형 자료에서 분할표 일부의 칸에서 도수가 붕괴(collapse)된 상태로 조사가 이루어진 것을 단계별추출(step-wise sampling)이라 한다. 단계별추출로 얻어진 자료를 분석할 경우 단계별추출법을 사용하여 분석하면 분석의 효과를 얻을 수 있다. 본 논문에서는 단계별추출법 중에서 최대우도추정법을 이용하여 얻어진 정확최대우도추정량(exact maximum likelihood estimator)과 단계별추출최대우도추정량을 연구하였다. 또한 MSE와 편향(bias)을 기준으로 모의실험을 통하여 두 추정법을 비교하였다.

We present various infrared two-color diagrams (2CDs) using WISE data for asymptotic giant branch (AGB) stars and Planetary Nebulae (PNe) and investigate possible evolutionary tracks. We use the sample of 5036 AGB stars, 660 post-AGB stars, and 2748 PNe in our Galaxy. For each object, we cross-identify the IRAS, AKARI, WISE, and 2MASS counterparts. To investigate the spectral evolution from AGB stars to PNe, we compare the theoretical model tracks of AGB stars and post-AGB stars with the observations on the IR 2CDs. We find that the theoretical dust shell model tracks can roughly explain the observations of AGB stars, post-AGB stars, and PNe on the various IR 2CDs. WISE data are useful in studying the evolution of AGB stars and PNe, especially for dim objects. We find that most observed color indices generally increase during the evolution from AGB stars to PNe. We also find that $Fe_{0.9}Mg_{0.1}O$ dust is useful to fit the observed WISE W3-W4 colors for O-rich AGB stars with thin dust shells.

We devise a layer-wise hint training method to improve the existing hint-based knowledge distillation (KD) training approach, which is employed for knowledge transfer in a teacher-student framework using a residual network (ResNet). To achieve this objective, the proposed method first iteratively trains the student ResNet and incrementally employs hint-based information extracted from the pretrained teacher ResNet containing several hint and guided layers. Next, typical softening factor-based KD training is performed using the previously estimated hint-based information. We compare the recognition accuracy of the proposed approach with that of KD training without hints, hint-based KD training, and ResNet-based layer-wise pretraining using reliable datasets, including CIFAR-10, CIFAR-100, and MNIST. When using the selected multiple hint-based information items and their layer-wise transfer in the proposed method, the trained student ResNet more accurately reflects the pretrained teacher ResNet's rich information than the baseline training methods, for all the benchmark datasets we consider in this study.

Let (X, d) be a compact metric space, and let $f:X{\rightarrow}X$ be a continuous map. We consider that if a positively continuum-wise expansiveness continuous map f has the positively shadowing property in the nonwandering set, then the topological entropy is positive.

An effective method for analyzing the stability of nonlinear systems is developed. After introducing a novel concept named the point- wise generalized Dahlquist constant for any mapping and presenting its useful properties, we show that the point-wise generalized Dahlquist constant is sufficient for characterizing the exponential stability of nonlinear systems.

본 논문에서는 효율적인 허프만 디코딩을 수행할 수 있도록 하기 위하여 Bit-wise comparison 방법을 제시하였다. 이 방법은 허프만 코딩 원리인 이진트리 구성에 기초하여 허프만 테이블을 재구성 함으로서 디코딩 사간의 단축 및 알고리즘의 간소화를 가져오도록 하였고, 이를 토대로 MPEG-2 AAC 디코더의 허프만 디코딩 부분에 적용함으로써 성능검증을 수행하였다.
