This study was conducted to analyze the nutrient compositions of stem and fruit of Opuntia ficus-indica var. saboten (OF) and Opuntia humifusa (OH). The results of the two-way analysis of variance test indicated that the parts, varieties and parts*varieties had influence on nutrient content except crude protein, soluble dietary fiber, Fe, Se, I, vitamin E, niacin and vitamin C. Moisture and crude ash content was higher in stem than in fruit, while crude lipid and insoluble dietary content was higher in fruit than in stem. Mineral content revealed that K (1,313.67 mg% in OF, 1,351.38 mg% in OH) was the highest in fruit and Ca (5,146.29 mg% in OF, 1,388.19 mg% in OH) was the highest in stem. Vitamin C was the most abundant vitamin in the fruit of OF (199.98 mg%) and OH (187.12 mg%). Polyunsaturated fatty acid was the highest among fatty acids (66.9~70.1%), with higher content in the stem (753.89 mg%) than fruit (578.01 mg%) in OF, while higher in the fruit (1,093.63 mg%) than stem (475.07 mg%) in OH. Moisture, crude protein, Mg, Se and riboflavin was higher in OF than OH; whereas, crude lipid, insoluble dietary fiber, total dietary fiber and monounsaturated fatty acid were higher in OH than OF. These results indicated that OF and OH could be a good food source for Ca, K and Vitamin C. Also, different nutrient content by parts and varieties, can be helpful in choice of parts or varieties for consumer purposes.

In this paper I will try to show how Wittgenstein criticized Frege's theory of meaning. Frege's theory of meaning can be compressed as sense-reference theory. Frege distinguishes between sense and reference on all the linguistic expressions. In particular, he regards that a sentence has sense and reference. This distinction was raised from, so to speak, the problem of identity sentences. Wittgenstein's "fundamental thought" of Tractatus Logico-Philosophicus is the key of his direct criticism of Frege's sense-reference theory. That is, it is an attack on Frege's thought that the reference of a sentence is a truth value and truth values are "objects themselves" (in Frege's meaning). According to Wittgenstein, such an object does not exist and according to his picture theory, the function of a name and that of a proposition are fundamentally different. By the way, Frege can reply justly to this criticism that it is insufficient. In short, Frege's 'sense' and 'reference' etc, are the technical terms. Hence Wittgenstein's decisive criticism of Frege's theory consists in accusing his theory of logical flaws. There is an another route to the sense and reference of a sentence which Frege introduces. In discourses of judgement stroke and content stroke in his Begriffsshrift and in those of horizontal stroke since his "Function and Concept", Frege deals with the sense and reference of a sentence. Wittgenstein criticize that the sense of a complex sentence such as ~p would by no means be determined by Frege's determination.

This study examines the procedure of successful novel adaptation. It is well known from precedent studies that narrative structure of novels should change forms to suit the media characteristics of films. But, the changing forms of narrative structure is not a sufficient condition of successful novel adaptation, but a necessary condition. A successful adaptation could be completed with filmic expressions on the presented narrative structure. The core of filmic expression is cinematic language which means the composition and array of image and sound. The novel, Kirishma Thing deals with everyday life of high school students and it consists of six stories which are narrated by one student each in first person point of view. The film, Kirishma Thing implemented a different strategy. It reveals the same events several times to show many characters over in each person's point of view in the first half. In the second half, all the characters gathers at the rooftop of the school to have an unilinear narrative structure over one event. This film utilize all kinds of cinematic language to achieve these structures including the widescreen aspect ratio which exposes as many characters as possible in one shot, picture composition which shows the same event in a different point of view, contrast in lighting and music which differentiates and empowers the last sequence of the film.

The purpose of this study is to analyze the damage pattern when overcurrent is applied to a thermal magnetic type molded case circuit breaker (MCCB) using a Primary Current Injection Test System (PCITS). When an overcurrent of 150 A was applied to the PCITS for 5 seconds with the trip bar of an MCCB being damaged, it was found that the surface of the temperature control device (bimetallic strip) positioned at the right was significantly carbonized. When an overcurrent of 300 A was applied to the PCITS for 5 s under the same conditions, the entire temperature control device was deteriorated, becoming flattened and in close contact with the MCCB. When an overcurrent of 450 A was applied to the PCITS for 5 s, the coil of the temperature control device was melted and disconnected. In addition, it was observed that the contacts, the enclosure and upper cover were deformed and there was a trace of carbonization on them. When approximately 3 s had elapsed after an overcurrent of 600 A was applied, white smoke occurred inside the MCCB and a flame was radiated out, after which the overcurrent supply stopped with "phutt" (whomp) sound. It was observed that when the same type of MCCB is damaged by a general flame, the surfaces of its handle, terminal, arc divider (extinguisher) and temperature control device were carbonized uniformly. In addition, it was found that the trip bar of the operating mechanism was melted down and the metal operation pin was moved while being tripped.

This paper introduces a risk graph which is one method for determining the SIL as a measure of the effectiveness of signaling system. The purpose of this research is to make up for the weakness of the qualitative determination, which has input value ambiguity and a boundary problem in the SIL range. The fuzzy input valuable consists of consequence, exposure, avoidance and demand rate. The fuzzy inference produces forty eight fuzzy rule by adapting the calibrated risk graph in the IEC 61511. The Max-min composition is utilized for the fuzzy inference. The result of the fuzzy inference is the fuzzy value. Therefore, using the de-fuzzification method, the result should be converted to a crisp value that can be utilized for real projects. Ultimately, the safety requirement for hazard is identified by proposing a SIL result with a tolerable hazard rate. For the validation the results of the proposed method, the fuzzy risk graph model is compared with the safety analysis of the signaling system in CENELEC SC 9XA WG A10 report.

This paper is a follow-up to previous papers entitled, "Development of Tunnel-Environment Monitoring System and Its Installation" I [1] and II [2]. The target tunnel of these studies is the Solan Tunnel, which is a loop-type, single-track, 16.7-km-long tunnel located in mountainous terrain and passing through the Baekdudaegan mountain range. It is an ordinary railway tunnel designed for both freight and passenger trains. We analyzed the environmental conditions of the tunnel using temperature and humidity data recorded over approximately one year. The data were recorded using the Tunnel Rough Environment Measuring System (TREMS), which measures environmental data in subway and high-speed train tunnels and is installed in three locations inside the tunnel. Previous studies analyzed environmental conditions inside tunnels located in or near a city, whereas the tunnel in this study is located in a mountainous area. The tunnel conditions were compared with those measured outside the tunnel for each month. Hourly changes during summer and winter periods were also analyzed, and the environmental conditions at different locations inside the tunnel were compared. The results are widely applicable in studies on the thermal environment and air quality of tunnels, as well as for computer analysis of tunnel airflow such as tunnel ventilation and fire simulations.

Burning rate of the matrix propellant($r_{sb}$) and burning rate along the metal wire($r_w$) were measured and analyzed for the HTPB/AP/Al propellant embedded with Ag wire($\phi$0.15mm) according to weight % of RDX(0~20%). Variation of burning rate increment ratio($r_w$/$r_{sb}$) and pressure exponent(n) was studied for the nitramine propellant having 10% RDX embedded with three kinds of metal(Ag, Cu, and Ni-Cr) of which diameter range is between 0.1~0.6mm. Maximum burning rate increment ratio of the nitramine propellant embedded with Ag wire($\phi$0.1mm) was 5.94 at $20^{\cire}C$, 1000 psia, 16.4% faster than that of HTPB/AP propellant, it is because that autoignition temperature of the nitramine propellant was higher than that of HTPB/AP propellant. Standard deviation of absolute ($r_{wc}$/$r_{we}$)/$r_{we}$ calculated by using new empiracal equation composed of four dimensionless groups, is 6.11% less than that calculated by using original empirical equation composed of three dimensionless group. The new empiracal equation is derived from Buckingham pi theorem using the parameters such as thermal diffusivity, melting temperature. wire diameter, propellant sample diameter, frame temperature, autoignition temperature and matrix burning rate which influence on $r_w$.

The purpose of this study is to raise the issue of the existing deinstitutionalization debate, considering only the shipment process to these two spaces, and still leaving the inter-facility circulation of vulnerable mental handicapped who are still hanging around the facility. In particular, we sought to supplement the discussion of deinstitutionalization by illuminating the problems of those who have to rely on facilities, as well as the mental health facility system and the homeless facility system. In the case of homeless persons with mental disabilities who repeatedly use the mental health facility system and the homeless facility system, they confirmed the pattern of using the facilities by constantly changing the place to manage the overlapping risk of mental illness and homelessness. Also it is triggered by the voluntary nature of the parties with no resources and resources. This situation appeared to be inevitable in the absence of resources and supportive systems that would actually enable a life in the community. Nevertheless, I asserted that the life of the mentally handicapped, which is circling the facility, is extremely unstable and is not desirable from a welfare point of view.

The purpose of this study is to analyze the relationship between entrepreneurship and entrepreneurial intention. This relationship has been conceptually addressed in many previous studies and has been empirically tested. However, this study is different from the previous studies in the following four points. First, we measured entrepreneurial intention by manipulating launching a start-up as a relative concept for employment, which is consistent with the conceptual definition of entrepreneurial intention (i.e. entrepreneurial decision making in the process of career choice). Second, it is distinguished from previous researches in that it uses the question of preference for "action" with regard to job choice. Third, we expanded the opportunity for discussion using the youth panel data of the Korea Employment Information Service. Fourth, the altruistic purpose is included in the category of entrepreneurship. Empirical results showed that intentions of entrepreneurship were stronger when the need for achievement was intense, internal control tendency was intended, risk-taking propensity was sturdy, and autonomous tendency was high. However, innovation and aggressiveness are not statistically related to entrepreneurial intention. On the other hand, the altruistic tendency was found to have a negative correlation with entrepreneurial intention. The results of this study can provide meaningful implications for both private sector investors and government policy makers.
