This study examines pre-college study abroad (PSA, Chogi yuhak), which is one of the fastest growing phenomena among the various efforts for Koreans to learn English. The discussion includes the reasons why PSA has become so popular in the last decade under the name of globalization, the problems it has caused, and its new impact that this phenomenon has on Korean mothers. This study argues that PSA boom provides Korean mothers with an opportunity to pursue their own self-realization by studying abroad with their school aged children. These "new wild geese" mothers, who make double investments in their own education as well as in their children's in the U.S. represent important aspects of the contemporary Korean society regarding education, gender and neoliberal social atmosphere.

We design and fabricate a widely tunable laser diode made of InGaAsP-InP. The diode is monolithically integrated with a wavelength-selective coupled-ring reflector and semiconductor amplifiers. For realization of a compact size device, deeply etched multi-mode interference couplers and square ring resonators composed of total-internal-reflection mirrors are adopted and fabricated using a self-aligned process. It is demonstrated that the laser diode exhibits single mode operation and 16 nm tuning range with side-mode-suppression-ratio exceeding 20 dB.

Objectives: The purpose of this study is to use in therapy through considering representative oriental philosophical thought in terms of psychotherapy and Oriental medicine. Methods: This study examines psychotherapy and oriental aspects of "Diagram theory of InShimDoShim" that Yulgok, a Neo-Confucian scholar in the Joseon Dynasty, wrote about action of the mind and suggests ways to use it. Results and Conclusion: Diagram theory of InShimDoShim contains much content that can be applied in psychotherapy. It has a positive perspective of human nature and looked at life as realization of nature and life as subjective self-realization. Positive and negative experiences of life are expressions of positive nature. By reinterpreting these experiences, humans contribute to the goal of life that expresses their nature in a healthy way. Yulgok defines a healthy mind capable of living a good life as "an inshim who listens to doshim's command". Therapists can adopt this mindset as the goal of psychotherapy. Yulgok said that the way of manifesting nature is only possible through energy, and that the clear and tidy of this temperament creates a healthy and unhealthy mind. In this part, it is possible to apply therapeutic intervention of the diagram theory of InShimDoShim and Oriental medicine. Oriental medicine can calm temperament by using a treatment method to regulate energy, and clear energy creates a healthy mind and body. The principle that the mind is composed of nature and energy provides a basis for psychosomatic medicine.

This paper presents the design and realization of a digital PV simulator with a Push-Pull Forward (PPF) circuit based on the principle of modular hardware and configurable software. A PPF circuit is chosen as the main circuit to restrain the magnetic biasing of the core for a DC-DC converter and to reduce the spike of the turn-off voltage across every switch. Control and I/O interface based on a personal computer (PC) and multifunction data acquisition card, can conveniently achieve the data acquisition and configuration of the control algorithm and interface due to the abundant software resources of computers. In addition, the control program developed in Matlab/Simulink can conveniently construct and adjust both the models and parameters. It can also run in real-time under the external mode of Simulink by loading the modules of the Real-Time Windows Target. The mathematic models of the Push-Pull Forward circuit and the digital PV simulator are established in this paper by the state-space averaging method. The pole-zero cancellation technique is employed and then its controller parameters are systematically designed based on the performance analysis of the root loci of the closed current loop with $k_i$ and $R_L$ as variables. A fuzzy PI controller based on the Takagi-Sugeno fuzzy model is applied to regulate the controller parameters self-adaptively according to the change of $R_L$ and the operating point of the PV simulator to match the controller parameters with $R_L$. The stationary and dynamic performances of the PV simulator are tested by experiments, and the experimental results show that the PV simulator has the merits of a wide effective working range, high steady-state accuracy and good dynamic performances.

The purpose of this work is to examine the viability of employing the prosody cloning technique in teaching English prosody. Ten native speakers of Korean high school students with similar level of English proficiency participated in the poem self-study experiment. Five of them were grouped into the experimental group and the remaining five into the control group. One popular English poem from a high school textbook was selected and its recording by a professional native speaker of English was used in the experiment. The members of the two groups made a recording of the poem both before and after the experiment. For the study material, the experimental group used their own recorded utterances with their prosody cloned from the professional English speaker, while the control group used the utterances of the professional speaker alone. The acoustic analysis of the recordings by the prosodic foot both before and after the experiment showed that the experimental group performed slightly better than the control group in the realization of the intensity contour of the poem. There were no significant differences in the realization of the intonation contour and segmental durations between the two groups. The recording after the experiment was also subjectively evaluated by a native speaker of English and the scores for the experimental group were slightly higher than the control group. These findings suggest that the use of English poems with the help of the prosody cloning technique is a potentially viable approach to teaching English intonation to high school students. A long-term study with more students is necessary.

Purpose: The purpose of this study was to understand and describe the illness experience of married Korean women with epilepsy. Methods: Data were collected during 2015~2016 through individual in-depth interviews with 12 married women with epilepsy. Verbatim transcripts were analyzed using Giorgi's phenomenological analysis to uncover the meaning of the illness experience of the participants. Results: The study results showed that the illness experience of married Korean women with epilepsy was clustered into a specific description of situated structure and a general description of situated structure. Six themes from 20 meaning units were identified: 1) Undermined self-esteem with stigma of being epileptic; 2) Limited social interaction; 3) Suffering sorrow as a 'disqualified being'; 4) Shuttling back and forth across the boundary between healthy and epileptic; 5) Desperate struggle to meet the expectation of given role; 6) Self-empowering through self-restriction and realization. Conclusion: The findings from this study show that both the enacted and felt stigma of epilepsy impact on the life of married Korean women with epilepsy. Although the participants face social and interpersonal restriction and prejudices, they try their best to fulfill their role rather than to be cared for as patients. As the stigma and hardships of the participants are related to lack of knowledge, health professionals should focus not just on clinical intervention but also on providing targeted educational programs and counseling for these women to dispel the stigma of the disease and to increase their quality of life.

In this paper, we investigated the method of compensation for optical pulse shape distortion due to both chromatic dispersion and SPM(self phase modulation) in a single mode fiber We selected MSSI(mid-span spectral inversion) as compensation method using OPC(optical phase conjugator). We used EOP(eye-opening penalty) parameter in order to evaluate the efficiency of waveform distortion compensation. In this paper, we induced optimum pump power level in optical phase conjugator through analytic method of computer simulation. And we investigated input signal power range being able to maintain stable reception performance under the condition of optimum pump power. We verified the possibility of high performance optical transmission system realization through the inducement and application of optimum pump power, input signal power and in-line amplifier spacing, because power control is important in the compensation for optical pulse distortion.

Patricia Waugh once regarded modernism fiction as 'the struggle for personal autonomy' against the opposition existing social institutions and conventions. Michael Cunningham's characterizations of Virginia Woolf and Septimus in The Hours show the two contrasting reactions to individual alienation and mental dissolution in the modern era. As the personifications of endurance and self-destruction against the mechanical power of contemporary world, Woolf and Septimus consist of just the world of diptych where the woman's role is confined to the angel in the house. By creating Mrs. Brown based upon his own alienated mother image, however, Cunningham succeeds in representing the more dramatically vivid world of triptych where woman can have her own room and self-realization despite still facing the dilemma of the traditional family. Accepting Joycean Bloom's optimistic and relaxing way of life in part, Mrs. Brown connects the labyrinths between the author's (and also Richard's) alienation with the theme of celebration of the life. Clarissa in postmodern New York setting is still a concealed and mystified character. Similar to Mrs. Dalloway, on the one hand Clarissa watches other people's tragedy with compassion. Cunningham's Clarissa, on the other hand, is no longer seeking for either winning or defeat in the spectacular world unlike her predecessors. In many resilient attitudes of everyday life Clarissa is closest to Mrs. Brown whom Virginia Woolf originally hopes to describe. Without any fear or rage toward the society Clarissa witnesses and achieves "the humanity, humour, depth" of female values by successfully turning the trivial life into an epic journey.

This study attempted to find individual reasons for inducing cybercrime. The survey was conducted targeting investigators and security experts on 11 types of cybercrime. There are 16 internal factors that cause crime and classified according to Maslow's 5 steps. As a result of the survey on a total of 176 items, the credibility of the Cronbach's Alpha coefficient was 0.925. The result of the factor analysis is as follows. Factor analysis results are maslow phase 1 physiological desire is commercial, sykes. Phase 2 safety desires are not punishable and crowd. The three-stage social desire is impulsiveness, indifference, etc. The fourth stage of respect is anonymity and honor. The desire for self-reality in stage 5 has been reduced to indesity, a loss of moderation, morality, and media effects. In conclusion, the physiological desire, the desire for respect for the crime of infringing on the information and communication network, the desire for menstruation, the desire for self-realization for the crime of using information and communication networks, the desire for self-actualization for the crime of illegal content. It was in the order of desire.

Purpose: This study explored the experiences of pregnant women with depressed mood participating in a group cognitive behavioral therapy (CBT) program using video communication, based on Beck's cognitive theory. Methods: The participants were six pregnant women out of 13 women who had participated in an 8-session group CBT program using video communication for women with depressed mood (Edinburgh Postnatal Depression score of ≥9). Data were collected from February 20 through March 25, 2021. In-depth individual interviews were conducted through a video conferencing platform at 1 month post-baseline. Thematic analysis was done. Results: Three themes, 10 subthemes, and 38 concepts were derived from experiences of participating in the 4-week group CBT program (twice a week). The first theme, entitled "continuing realization" had subthemes of "a negative and instable self," "a selfish judgment that excludes others," and "a strong belief in self-control." The second theme, entitled "attempt to change for restoration" had subthemes of "shift to rational thinking," "freedom from suppressed beliefs," "tolerance of other people," and "courage for self-expression." The third theme, entitled "departure for a positive life," had subthemes of "emotional healing," "faith in oneself," and "reestablishing the criteria for happiness." Conclusion: Pregnant women with depressed mood expressed that continuing realizations and attempts to change supported their transition toward a positive direction of healing. Thus, they were able to change their distorted thinking into rational thinking through CBT using video communication. These findings support the use of group CBT using video communication with pregnant women who have depressed mood.
