  • This paper describes speed control of a permanent split capacitor single phase induction motor using SHE PWM inverters. The inverter is controlled by V55 microprocessor and its range is larger than other systems. Due to the V/F control with SHE(Selected Harmonic Elimination) PWM, continuously variable speed is attained and THD(Total Harmonic Distortion) is decreased. This is verified by simulations and experimental results.

  • Relatively young widows, who are left with young children by a sudden death of their husbands, will be faced with not only psychological troubles such as individual anxiety and frustration but also the dual burden of playing both father and mother roles in a family, Also, family members have difficulty in adapting themselves to new circumstances of the family system, the training and raising of family members, and management of the family economy. In this study, the realistic resources on the experience of middle-aged women who are bereaved of their husbands by accidents were explored. The purpose of this study is to help widows adapt to life in society and live a more positive life by setting a new goals and recovering from a lost and twisted life. 11 women, who have experienced the loss their husbands and live in the Seoul metropolitan area were studied. The research took 116 days from December 15, 1995 to April 8, 1996. The method of research was direct interviews. While having interviews with them, the contents were recorded with their consent. The ground theory was that used by Strauss & Corbin(1990) in the analysis of the data. 81 concepts were analyzed and they were subdirided into 22 subordinate categories through the course of the analysis. These were then classified into 9 general categories. In the course of being categorized, 'absurdity' was showed as a core category. The subordinate categories 'surprise', 'gloom', 'grudge', 'helplessness', 'emptiness', and 'loss' were united in the core category 'absurdity'. Ominous presentiment, belated notice, death, surprise, gloom, grudge, helplessness, emptiness, loss, the situation of the children, lack of support from neighbors, support from neighbors, mulling over ways to live, choosing a job, strengthening, reinforcement, burden, sadness, smoldering, yearning, overcoming these 22 subordinate categories were re-composed into 9 general ones the husband's death, absurdity, presence of children, existence of support, self-support ability, preparation of countermeasures, self-reinforcement, toilsomeness, and overcoming. 'Absurdity' widows experience was shown in the results of 'toilsomeness' and 'overcoming' through reaction, confrontation, and adaptation. According to the analysis the central phenomenon was absurdity, the causal condition of the death of a husband, the presence of children and the existence of support, and the meditated situation of self-support. To solve absurdity, the preparation of countermeasures and self-reinforcements were shown resulting in toilsomeness and overcoming. Through the contrast in the data, the following statements were deduced: (1) If the death of the husband is expected, the more a widow will feel absurdity. (2) The more children she has and the younger she is, the more a widow will feel absurdity. (3) The lower support she is given, the more a widow will feel absurdity. (4) The larger self-ability she has, the more actively she will prepare countermeasures. (5) The smaller self-ability she has, the more passively she will prepare countermeasures. (6) The larger self-ability she has, the weaker self-reinforcement she will preform. (7) The smaller self-ability she has, the stronger self-reinforcement she will perform. (8) The more actively she prepares countermeasures for absurdity, the better she will overcome. (9) The more passively she prepares counter measure for absurdity, the worse she will overcome. (10) The stronger self-reinforcement for absurdity she performs, the better she will overcome. (11) The weaker self-reinforcement for absurdity she performs, the worse she will overcome. Through the results in this study, the following suggested: 1) A study whose object is all family members, and a comparative study on the case of a husband who has lost his wife should be done. These studies can be expected to develop a more refined theory. 2) Because of the collapse of the extended family system and the changes of family culture in Korea, a widow's status and position are apt to be ambiguous between her husband's home and her parent's. Therefore a new study on family culture should be made. 3) A continuous study on growing social Self Help Groups should be requested for the widows of this study to re-establish and recover from their twisted and scattered lives.

  • Background: This study is aimed at identifying the anti-inflammatory properties of 70% ethanol extract produced from an edible brown seaweed Sargassum horneri (SJB-SHE) with industrial-scale production by Seojin Biotech Co. Ltd. S. horneri is a rich source of nutrient and abundantly growing along the shores of Jeju, South Korea. Methods: Here, we investigated the effect of SJB-SHE on LPS-activated RAW 264.7 macrophages. The cytotoxicity and NO production of SJB-SHE were evaluated using MTT and Griess assays, respectively. Additionally, protein expression and gene expression levels were quantified using ELISA, Western blots, and RT-qPCR. Results: Our results indicated that pre-treatment of RAW 264.7 macrophages with SJB-SHE significantly inhibited LPS-induced NO and $PGE_2$ production. SJB-SHE downregulated the proteins and genes expression of LPS-induced iNOS and COX2. Additionally, SJB-SHE downregulated LPS-induced production of pro-inflammatory cytokines (tumor necrosis factor-${\alpha}$, interleukin (IL)-6, and IL-$1{\beta}$). Furthermore, SJB-SHE inhibited nuclear factor kappa-B (NF-${\kappa}B$) activation and translocation to the nucleus. SJB-SHE also suppressed the phosphorylation of mitogen-activated protein kinases (ERK1/2 and JNK). Conclusions: Collectively, our results demonstrated that SJB-SHE has a potential anti-inflammatory property to use as a functional food ingredient in the future.

  • Motherhood as an ideological construction has been regarded as an oppressing apparatus enforced by patriarchism. On the one hand, demystifying motherhood helps expose dehumanization of women, and accordingly liberate women from being an ideal mother. On the other hand, however, feminists' attempts to unearth the distorted images of mothers result in devaluation of such values as love and sacrifice attached to motherhood. "Tell Me a Riddle" by Tillie Olsen, who is a declared socialist as well as a feminist, occupies a significant position in a sense that it neither condemns motherhood as evil nor idealizes it. Through the main character, Eva, it examines the meaning of motherhood in a way that a real mother experiences it in a real life, and thus Olsen challenges the readers to ponder upon the mothers' dilemma: a conflict between a desire for self-fulfillment and sacrifice for others. Eva, a mother of seven grown-up children, and now dying, shows an ambivalent attitude toward motherhood. She realizes that she is a victim of idealized motherhood in that, toward the end of her life, she feels uncomfortable accepting her personal desires as they are. Yet at the same time, she appreciates her experiences as a mother in that she could consume her passion for the ideals as she has spent her youth working toward, trying to construct an idealistic socialist country. Eva's real ideal, as a human being, is to live "with" others, not just "for" others. In other words, she does not want to allow herself to live only for others in the name of the mother because she does not have any alternatives to do otherwise. Rather, she desires to live a life of voluntary sacrifice and love. In this way, through Eva, Olsen tries to help us to construct a community where we--not just mothers-can live "with" others.

  • Background and Objectives : The aim of this study was to investigate the anti-oxidant, anti-allergic and anti-inflammatory ability of the Taglisodog-eum(SHE) extract on the RAW 264.7 and EL4 cells Materials and Methods : Three types of experiments were implemented for this study: first, the experiment to study the anti-oxidant effect of SHE using Riboflavin; second, in vitro experiment to investigate the inhibition of Th 2 cell differentiation by SHE using EL4 cells (IL-4 mRNA expression); third, the suppression of $NF-{\kappa}B$ activation using RAW 264.7 cells (iNOS and COX-2 mRNA expression). Results : The anti-oxidant ability of SHE were dose-dependantly increased. From in vitro, the LPS-induced iNOS and COX-2 mRNA expression were dose-dependantly decreased in the RAW264.7 cells treated with SHE and the PMA-induced IL-4 mRNA expression were also dose-dependantly decreased in EL4 cells. $NF-{\kappa}B$ activation was suppressed, and iNOS & COX-2 production were inhibited by SHE Conclusion : The results suggest that SHE has dose-dependant anti-oxidant ability, and has anti-allergic and anti-inflammatory effects through the suppression of $NF-{\kappa}B$ activation and the inhibition of Th 2 cell differentiation.

  • While Janis Joplin is generally known as a hippie rock star of an untimely death to Korean audience, she is more strongly evoked in the image of blues mama in American context. Blues, definitely based on African-American vernacular tradition, is defined as a matrix, which is "a point of ceaseless input and output, a web of intersecting, crisscrossing impulses always in productive transit," to borrow Houston A. Baker's expression. This article explores how her life and music can be understood in blues tradition, especially in terms of personal and social transgression for which she was criticized, focusing on her blues performance. First of all, born and growing up in southern Texas between 1940s and 1960s, she expressed her innate suspicion against segregation and white supremacy, actively embracing rich black musical heritage of the area. Second, against the normative social and moral expectation of a middle class white woman to be a suburban housewife, she sought her own desire, whether it was professional ambition or sexual possibility. Third, beyond the selling image of a heterosexually lascivious blues mama, she dared to be a homosexual and bisexual, while it was not publically acknowledged. Along with her alcohol and drug dependence, such transgressions against normative social expectation were not made without her inner conflict, leaving a trace of trauma, hesitation, and the blues. While she was "buried alive in the blues," as a sacrifice at the altar of the 1960s, she still remains "alive" provoking "fire inside of everyone of us."

  • Cinema costume can stimulate the public to synchronize with and replicate what they see in the movies. Especially when the public thinks the stars in the movies . Especially when the public thinks the stars in the movies are beautiful or dramatic the styles of cinema costumes powerfully affect them. Thus cinema costume designers quickey become fashion designers. Edith Head who strongly believed cinema costumes to be an effective means of portraying the Character's personality and psychological make-up was an innovative designer whose costumes manifested this belief. She enhanced the character's individual image and distinction for the public through her artistic design in costumes. She adapted a realistic approach but her costumes invariably produced aesthetic ef-fects. Since the Academy Awards added the category of costume design she led the field with 35 nominations and eight oscars during 33 years of her productive work. Edith head was a dominant figure in costume design; her creations were highly renowned as an art form while they gained popularity. The purpose of this study was to reveal the ef-fects of Edith Head's cinema costume designs on fashion. This study was also to emphasize the powerful influence on ashion of cinema costume and cinema costume designers in general. The study was done through literature movies for which she created costumes fashion magazines and Edith Head's original sketches. The influence of Edith Head's costume de-sign on fashion is as follows: 1. She introduced and lead the casual fashion in the 1950's combining simplicity and sophistication. 2. She altered uniforms and reconstructed public clothing for multiple functions. 3. She rearranged high school prom dresses through the movie 'A Place in the Sun" to en-hance characteristic of each gender and the Dandy Look of the 1930's into men's apparel in the 1970's through the movie "The Sting" 4. She expanded the traditional style in the 1940's and became a leader in ecological style. 5. She adapted glitter from astronaut's ap-parel into public clothing. 6. She resturctured Sabrina Pants in the 1960's to accentuate the individuals strength by overcoming one's weakness without minimi-zing it's aesthetic appeal and reintroduced the pants in the 1990's. 7. She introduced elegant negligees to gen-eral public and maintained it in the public do-main. As it is revealed Edith Head's costume de-sign not only impacted the field of fashion dur-ing her time but also is presently influencing modern fashion throughout the world as it is witnessed by repeated reintroduction of her fashion styles. Reviewing her cinema costumes it is concluded that cinema costumes it is concluded that cinema costumes powerfully af-fect the public through a visual channel more than any other routes. Cinema costumes can become the origin of fashion by stimulating the public to synchronize with and replicate what they see in the movies. Since cinema costumes can launch fashion trend it requires further research. Based on what is revealed in this study. it would be beneficial to examine how cinema costumes affect people socially and culturally and how they could provide resources for re-search in fashion trends. It is also the writers opinion that there should be more designers such as Edith head who could lead the field of costume design into the twenty-first century.
