Objective: The purpose of this study was to investigate whether addition of konjac gel with three different vegetable powders can increase quality of low-fat frankfurter-type sausage. Methods: Low-fat frankfurter-type sausages were manufactured with formulations containing konjac gel and three vegetable powders (aloe vera, cactus pear, or wheat sprout) as pork fat replacers. The formulations of frankfurters were as follows: NF (normal-fat; 20% pork fat), LF (low-fat; 10% pork fat), KG (low-fat; 10% pork fat+10% konjac gel), and konjac gel with three vegetable powders (KV), such as KV-AV (10% pork fat+10% konjac gel with aloe vera), KV-CP (10% pork fat+10% konjac gel with cactus pear), and KV-WS (10% pork fat+10% konjac gel with wheat sprout). Proximate analysis, pH value, color evaluation, cooking loss, water-holding capacity, emulsion stability, apparent viscosity, texture profile analysis, and sensory evaluation were determined. Results: The konjac gel containing groups showed lower fat content (p<0.05) and higher moisture content than NF group (p<0.05). The pH value of frankfurters was decreased in three KV groups (p<0.05). The three KV groups had increased dark color (p<0.05) compared with KG, and KV-CP had the highest redness (p<0.05). The water-holding capacity and emulsion stability were higher in the three KV groups than KG and LF (p<0.05). Cooking loss was generally decreased in the three KV groups, compared with KG (p<0.05). The apparent viscosity of KV groups was similar with NF group and overall texture properties were improved in KV-CP. In the sensory evaluation, the highest overall acceptability was found in KV-CP groups (p<0.05). Conclusion: The four fat replacers improved physicochemical properties of low-fat frankfurters. Particularly, konjac gel with cactus pear powder seems more acceptable as a pork fat replacer.

We describe three feather mites recovered from a wood sandpiper Tringa glareola that was stored in a $-20^{\circ}C$ freezer at the Chungnam Wild Animal Rescue Center. These feather mites are reported for the first time in South Korea: Avenzoaria totani (Canestrini, 1978), Ingrassia veligera Oudemans, 1904 and Montchadskiana glareolae Dabert and Ehrnsberger, 1999. In this study, we provide morphological diagnoses and illustrations. Additionally, we provide partial sequences of the mitochondrial cytochrome c oxidase subunit I(COI) gene as molecular characteristics of three species.

The astronomical understanding of the heavens in "Hwangje-Naegyeong" can be divided into three main fields: the theory of cosmos, astronomy and calender. "Hwangie-Naegyeong" comprised the theory of cosmos, astronomy and calender established in the Han period. Astronomy was to describe the heavenly world and to interpret its phenomena. Calendar was to make numerical representations of the observations of all kinds of celestial bodies and to give them number-mystical meanings. Theory of cosmos treated what ancient Chinese speculated on the structure of the heavens including the earth. These three fields developed independently. However, they can also be be combined into one tradition, the astronomical knowledge. In the Han period that the astronomical knowledge grew from the mere accumulation of primitive knowledge to the established form. Throughout the Chinese history, the essential contents of astronomical knowledge including the theory of calendar, did not change much from what they were in Han period. "Hwangje-Naegyeong" use the lunisolar calendar(太陰太陽曆) and the Calendar in the late Han period(後漢四分曆). The use of the subdivisions of the seasons(24節氣) and the leap month(閏月) in "Hwangje-Naegyeong" means that it adopted the lunisolar calendar. Also "Hwangje-Naegyeong" adopted the Calendar in the late Han period by the four points: "Hwangje-Naegveong" ruled the circulation of the universe(周天度數) at 365, 1/4 terms, use the The Twenty Eight Constellations in astronomical observation, view the heavenly body by the ecliptic(黃道) and mark down year by the Heavenly Streams & Earthly Branches(干支紀年), The 24 solar terms is made by amount of Yang-Gi(陽氣) and samyum and samyang(三陰三陽) represent the amount of Yang-Gi in the earth.

This paper is written in order to research for the contents and expression of HanYongUn's Sijo. HanYongUn is very famous as monk and independent campaigner, modern poet in Korea. He wrote many kinds of literary works, for example, many modern poetry, modern novels, Sijo, Chino-Korean Poetry etc. It's very exceptional that he wrote a lot of Korean traditional Sijo and Chino-Korean Poetry. Because he was a many modern poet as same as modern novelist. So studying on his Sijo can help someone to understand the essence of HanYongUn's all literature. That's why I'm studying on HanYongUn's Sijo. The firstly, in aspect of the the contents of HanYongUn's Sijo, HanYongUn was expressing three kinds of themes, that is ideology, reality, daily life in his Sijo. The ideology consists of Buddhism and Confucianism and the reality is related with social conditions, the daily life is deeply connected with Nim. These features of his Sijo are different from his modern poetry and Chino-Korean Poetry which had a simple theme, for example, love with Nim, daily life. The secondly, in aspect of the expression of HanYongUn's Sijo, I studied the expression of HanYongUn's Sijo in three angles, that is, vocabulary and the developing of poet thinking, rhetorics. HanYongUn used essential words for expressing three kinds of themes effectively in his Sijo. And he was developing of his poet thinking by three steps in his Sijo. He applied several representative rhetorics to his Sijo, those are question and answer, exclamation, irony, distich etc. Even though I studied the characteristics of HanYongUn's Sijo in two aspects But there could be the other things to study about these kinds of theme. I might continue researching the other kinds of theme next time in the near future.

A new three phase three-level Pulse Width Modulation (PWM) Switched Voltage Source (SVS) inverter with zero neutral point potential is proposed. The major advantage is that the peak value of the phase output voltage is twice as high as that of the conventional neutral-point-clamped (NPC) PWM inverter. Furthermore, three-level waveforms of the proposed inverter can be achieved without switch voltage unbalance problem. Since the average neutral point potential of the proposed inverter is zero, the common ground between input stage and output stage is possible. The proposed inverter is verified by experimental results based on a laboratory prototype.

This paper proposes a novel current control strategy for current regulated VSI-PWM transistor inverter. The conventional hysteresis control method has good dynamic responses. But the switching frequencies are high because it does not optimize switching patterns. Proposed current control strategy can optimize switching patterns. As regulator, three level comparators are used. The outputs of the comparators select appropriate inverter output voltage vectors via switching table stored in EPROM. The simulation and exparimental results in comparison to contentional hysteresis strategy are presented and discussed.

In this paper, the fault current limiting operations of three-phase transformer type superconducting fault current limiter (SFCL) using double quench, which consisted of E-I iron core with three legs wound by primary and secondary windings and two superconducting modules (SCMs), were analyzed according to three-phase ground fault types. To verify the effective operation of the three-phase transformer type SFCL using double quench, the test circuit for three-phase ground faults was constructed, and the fault current tests were carried out. Through analysis on the fault current test results, the different fault current limiting characteristics of three-phase transformer type SFCL using double quench from three-phase transformer type SFCL using three SCMs were discussed.
