A total of 8 hwang-toh mortar mixes with no cement were tested to evaluate the effect of different fibers and admixtures on the control of shrinkage cracks of such mortars. The fiber types added were Lyocell, Poly-Amid and PVA, while, CSA and organic polymer were selected as the admixture. The shrinkage crack resistance of hwang-toh mortar were examined from the unrestrained drying shrinkage strain, restrained drying shrinkage and plastic shrinkage. Test results revealed that the unrestrained drying shrinkage strain of hwang-toh mortar sharply increased at an early age showing approximately 2.5 times higher values than predictions obtained from ACI 209, regardless of the addition of fibers and admixtures. In addition, cracks owing to the restrained drying shrinkage developed at the only age of 1.6 days in all test mixes; as a result, the cracking grade of hwang-toh mortar was evaluated to be high. On the other hand, the addition of fibers required a value of fiber spacing above 0.0003 in order to enhance the tensile resistance capacity of hwang-toh mortar under the restrained drying shrinkage and reduce the cracking area under the plastic shrinkage. Overall, it could be concluded that moist curing at an early age and the addition of fiber with fiber spacing above 0.0003 are practically effective in reducing shrinkage crack of hwang-toh mortar.

This study focus on the development of new molding ways of the cultured marble washbasin & bathtub to produce higher quality goods. On looking back upon the past 30 years in the market of the washbasin & bathtub, our product quality level was below the standard and the production facility was largely imported goods. And the inferior quality leads to the unsatisfaction of customer. But the leading companies are have been concentrated their effort on the productivity and quality improvement. In this study, we introduced the success case of ‘BACHE’ which gained productivity improvement by developing the molding process.

Evolution of Feeling of Free Will

( Hwang¸ Hyun Kyu ) 동국대학교 영어권문화연구소 2018 영어권문화연구 Vol.11 No.2

In this article, I will first make a distinction between belief of free will and feeling of free will and claim that even though it seems plausible to say that only humans have belief of free will, feeling of free will might be something different and therefore might exist in nonhuman animals as well. To illustrate this point, researches from psychologists, such as Baumeister to those from neuroscientists are dealt. Then, I will delve further into the feeling of free will and make the case that humans have feeling of free will not because we actually have free will but because this type of feeling evolved. I will then present possible theories including various evolutionary theories that try to explain how feeling of free will has evolved in humans. I will conclude the article by mentioning the implications and limitations of the study and end it with suggestions for further researches.

황주성,황규윤,안규동,이병국 순천향대학교 산업의학연구소 1997 순천향산업의학 Vol.3 No.1

The purpose of this study was to obtain information on the working environment, rate of environmental measurement over TLVs, the number of workers who were exposed to hazardous agents and, the examined rate of special health examination(SHE) in different types of industries. Authors investigate the reports on the working environmental status of the 101 industries in Cheonan area and result of SHE of those industries. The results were as follows : 1. Out of 101 industries under study, only 54 industries took special health examination. 2. While 85.3%(6,590) of 7,726 workers working in 101 industries were exposed to one or more hazardous agents, 88.4% of 5,867 workers working in 54 industries with special health examination were exposed to those agents & 75..4% of 1,859 workers working in 47 industries without any special health examination were exposed to those agents. But according to the criteria of selecting eligible workers for special health examination, only 32%(1,935/5,867) of total workers in the later industries were classified as eligible for the special health examination. 3. While rate of environment measurement of 101 industries TLVs who 25.5%, that of 54 industries with SHE was 29.8 & that of 47 industries without SHE was 16.1%, while the rate of noise and dust measurement over TLVs of 54 industries with SHE was 31.7%, and 25.3%, those of 47 industries without SHE was 13.6% & 35.6%, among 54 industries with SHE the rate of environmental measurement over TLVs was highest in clothes & leathers(47.0%) and that of foods(32.3%) and primary metal(31.3%). One the other hand, among 47 industries without SHE the rate of environmental measurement over TLVs was highest in paper & printing(44.9%) and that primary metal(15.8%), metaloid mineral(15.5%). 4. The examined rate of SHE of 54 industries was 92.7% as a whole. By type of industries the rate of primary metal(221.4%), foods(181.7%), chemicals(120.4%) were exceeded expected percent(100%) but the rate of metalloid mineral(53.0%), paper & printing(63.8%), machinery(72.2%) were far below the expected percent. 5. Only 4.7% of total workers working in 47 industries without SHE were classified as eligible workers for SHE. Among those eligible workers 48.9% were belonged to potential workers for SHE of noise. 6. The response rate of questionnaire was 70.4%(38/54) in 54 industries wirh SHE & 48.9%(23/47) in 47 industries. The necessity of environment measure was positively answer in 81.6% of 38 with SHE & 87% of 23 without SHE. On the other hand, the necessity of SHE was positively answered in 68.4% with SHE & 21.7% without SHE.

A Study on the Establishment of Destination Image through Mass Media

Hwang,Kyu-sung,Baik,Yu-kyung,Moon,Hye-young 세계문화관광학회 2007 Conference Proceedings Vol.8 No.0

As the products of mass media, such as drama, movies, and commercial advertisements have grown and entertained us, they induced people to visit the locations where they were filmed. However, little has been known what effects in movies or television-induced locations on tourism. The purpose of this study is to investigate the effects of the products of mass media on tourism through locations induced by dramas, movies, and commercial advertisements. More specially, this study examined the relationships between the perceptions of movies or television-induced affective response, the perceptions of movies or television-induced attributes and movies or television-induced destination images on tourism. Findings suggest that if audiences enjoy delightful movies, they will feel destination images with fun and delightfulness when they visit the location scene. Also, the results suggest that if dramas and movies gain in public favor, the location where they are filmed will become a new and fantastic destination to people.

Iconicity in English Lexical Category Phrases and Sentential Complementation from a Generative Perspective

Kyu-Hong Hwang(황규홍) 한국생성문법학회 2006 생성문법연구 Vol.16 No.3

  The generative view of autonomy of syntax has been criticized by most cognitive-functional grammarians and claimed to be incompatible with or unable to account for iconicity that exits in natural human languages. Given this, this paper attempts to explain some iconic aspects in English syntax from a generative perspective in an effort to argue against this cognitive-functional criticism. After examining "structure-concept iconicity" in lexical category phrases and sentential complementation in Newmeyer"s (1992, 1998) sense, I propose the following generative principles of iconicity, embellishing Hwang"s (2005) idea: (ⅰ) when a head is modified by multiple adjuncts, the fewer maximal projections of the head there are between the head and the adjunct, the closer the semantic relation between them is; (ⅱ) when a verb takes minimal pair/set clausal complements, the fewer and morphologically poorer functional heads(C and T) there are between the matrix verb and its clausal complement, the closer the semantic relation between them is. I then claim that Haiman"s (1983, 1985, 1994)"s iconicity of distance, a sub-principle of structure-concept iconicity, is compatible with generative grammar, to a large extent, in that it is well represented structurally in generative grammar outlined in Chomsky (1995, 2001, 2005): the semantically closer the two syntactic objects are, the more local their syntactic relation is in the light of hierarchical structure.

Interleukin-2가 Mouse 자궁선상피세포의 미세구조에 미치는 영향

황규성,김원규,이규식,정호삼 한양대학교 의과대학 1990 한양의대 학술지 Vol.10 No.1

It is well known that the endometrium of uterus changes histologically during the estrous cycle in rodents. Interleukin-2, a kind of lymphokine produced by the T lymphocyte activated by antigen or mitogen, induces antitumor effect by stimulating the proliferation of helper and cytotoxic T lymphocytes, augmenting the cytolytic activities of the cytotoxic T lymphocyte and differentiating a precursor cell into a lymphokine-activated killer cel in vivo. Although interleukin-2 suppresses the metastasis of the malignant tumor into the adjacent organs and the tumor itself, it develops many side effects including fever, chills and decreased hepatic functions. Interleukin-2 also causes increase of capillary permeability with weight gain, pulmonary edema and ascites. In this experiment, the author studied the effect of interleukin-2 on the mouse uterine glandular cells, observing electron microscopically the changes in cytoplasmic organelles of uterine glandular epithelial cells in mice. Totals of 20 healthy female mice, DDY strain, weighing about 20 gm and exhibiting normal estrous cycle, were used as experimental animals were injected with 2 million units of interleukin-2 diluted in 0.2ml distilled water per kg of body weight and with 0.2ml of normal saline per kg of body weight in the control group for 5 days. And animals were sacrificed at 5th day after administration of interleukin-2. The specimens obtained from te corpus uteri were pre-fixed in 2% glutaradehyde-2.5% paraformaldehyde buffered in Millonig's phosphate solution (pH 7.2) and post-fixed in the 1% osmium tetroxide. After dehydration the specimens were embedded in Epon 812. Ultrathin sections, 600-800A in thickness, were made and double stained with uranyl acetate and lead citrate. And these preparations were observed with the electron microscope. The results obtained were as follows. 1. Microvilli were reduced and microfilaments in microvilli were degenerated. 2. The pronounced dilatation, sacculation and fragmentation of the cisternae of rough endoplasmic reticulum was associated with detachment of the membrane-bound ribosomes. 3. The formation of secondary lysosomes such as autophagic vacuoies and multivesicular bodies were observed. 4. Cristae of the some mitochondria were arranged irregularly and dissociated. Consequently, the results obtained in the present study suggest that interleukin-2 appears to be cytotoxic to the uterine glandular cells of the mouse and induces the degenerative changes of the uterine glandular cells.

Species membership in claiming rights : Critique of Elizabeth Anderson’s essay “Animal rights and the values of nonhuman life”

( Hwang¸ Hyun-kyu ) 동국대학교 영어권문화연구소 2016 영어권문화연구 Vol.9 No.2

In this paper, I criticize Elizabeth Anderson's claim that species membership matters in deciding what rights one can claim. In her essay “Animal rights and the values of nonhuman life”, Elizabeth Anderson claims that species membership matters in deciding whether one can claim positive right to human provision. Justification for her claim is that only members of ‘our’ group have positive rights to the group's provision while beings that are not included in ‘our’ group do not have positive rights to the group's provision. Since species difference does indeed decide who is included in ‘our’ group and who is left out, Anderson concludes that species membership decides who can claim positive right to human provision. I claim that Anderson's premise that species difference decides who is included in ‘our’ group is unjustified. I also claim that even if we grant that this premise is true (after revising the premise a little bit), this revised version of premise would force Anderson to accept a conclusion that would be unacceptable. Since Anderson would not be able to accept this ridiculous conclusion, I conclude this paper by claiming that Anderson's claim that species membership makes difference in who gets positive right to human provision is unjustified.

An Iconicity-theoretic Approach to the English Dative Alternation Construction Kim, Kwang-Hyun · Hwang, Kyu-Hong This paper aims to examine the semantic and structural differences between the double-object construction and its prepositional counterpart based on Haiman's (1980, 1983, 1985) iconicity theory. The alternation phenomena have attracted a great deal of attention, and a range of proposals have been put forward to account for them. In particular, an attempt has been made among the majority of scholars to differentiate the double-object construction and its corresponding dative construction by resorting to the differences in verb meaning and those in relation between arguments. To achieve the above goal, in this paper, we attempt to identify the subtle meaning differences between the two constructions by way of the distance principle of the iconicity theory: "the linguistic distance between expressions corresponds to the conceptual distance between them." Namely, we argue that the double-object construction is used when the agent and the recipient are conceptually close, while the dative counterpart is used when the conceptual distance between the two is remote. This line of approach seems to be appealing in that it can explain the differences between the constructions more explicitly and systematically and in that it can also account for other alternation phenomena such as locative and conative constructions in a similar context.
