To supply the monitoring program for evaluating solar hot water heater, this research was purpose to improve the technical development of the enterprise for producing solar-heat hot-water-boiler and served as an aid for the enlargement and the popularization on solar energy.

한국어의 인칭범주 : 프랑스어 인칭체계와 비교연구 Etude compare´e avec le syste`me de la personne franc¸aise

박동열 한국 프랑스어문교육학회 2003 프랑스어문교육 Vol.15 No.-

La cate´gorie de la personne est indispensable dans l'acte de langage pour e^tre promue a` la dicibilite´. C'est a` dire que cette cate´gorie se pre´sente comme une condition fondamentale du langage et domine effectivement les syste`mes de l'espace et du temps. En franc¸ais, la personne locutive est elle-me^me analysable en terme d'espace et du temps. Dans ce rapport, sur le plan spatial, il proce`de d'une premie`re ope´ration de se´paration du Moi et du Hors-Moi. L'Hors-moi s'organise a` son tour selon le principe d'ite´rativite´, c'est-a`-dire qu'il se´pare toi de lui. Sur le plan temporel, le 'moi' devient 'je' et inclut le 'toi' qui devient 'tu', dans le rapport d'interlocution qui prend comme repe`re de temps l'instant de parole. C'est ainsi qu'on peut obtenir un syste`me de repre´sentation des personnes ranc¸aises et qu'on accorde la place aux le`re et 2e personne et celle accorde ´e a` la 3e personne. Par ailleurs, ce qu'on entend par la personne ne re´fe`re pas seulement a` une cate´gorie grammaticale purement formelle, mais aussi a` la pre ´sence humaine. Pour ainsi dire, la personne ne peut pas e^tre conside´re´e seulement au plan de l'e´nonce´, mais aussi au plan de l'e´nonciation. Le syste`me ordinal de la personne du franc¸aise a sa source dans un contrat associatif entre la personne de langage (la personne discours) et la personne de langue. En revanche, en core´en, on ne trouve non seulement pas de pronoms personnels intra-verbaux qui repre´senteraient le pocuteur et l'allocutaire, mais aussi les indicateurs core´eens correspondant au pronom personnel en franc¸ais, sont nombreux et diversifie´s l'extre^me. Cela veut dire que le core´en ne constitue pas en langue un syste`me ferme´, c'est-a`-dire, une repre´sentation de personne. Autrement dit, les personnes parlantes et e´coutantes ne s'inte´riorisent pas dans la langue. Mais, me^me si le core´en ne posse`de pas de personne de la langue, les e´nonce´s core´ens identifient la personne par le contexte et dans l'e´nonciation ou` la personne parlante est relativise´e par des conside´rations socio-culturelles ou socio-hie´rarchiques a` l'e´gard de la personne e´coutante. On peut trouver des traces d'ope´rations d'institutionnalisation des participants a` l'e´nonciation par, d'une part, des morphe`mes grammaticaux et par, d'autre part, certains types de pre´dicat qui sont lie´s aux instances e´nonciatives et impliquent des participants, sans marques explicites de de´termination re´fe´rentielle. Donc le core´en n'a pas de personne de la langue, mais la belle personne du discours.

In this study, we compared backpropagation network(BPNN) with probabilistic neural network(PNN) as the classification algorithm of welding flaws. For this purpose variables are appied the same to two algorithm. Here, feature variable is composed of time signal itself and frequency signal itself. Those are ultrasonic signals reflected on welding flaws. Through this process, we comfirmed advantages/disadvantages of two algorithms, identified application methods of two algorithms to classification methods of welding flaws. These advantages/disadvantages and application methods are based on theoretical backgrounds.

光州圈 觀光호텔 營業서비스職 從事員의 意識構造

崔東烈 서강전문대학 1994 論文集 Vol.13 No.-

In the day of reform, hotel industry should promote efficiency of internal control. For that reason, the most important thing in the hotel industry is the management of human agency. Hereafter, the success or failure of hotel management is dependent upon upbringing and efficient use of experts. From this point of view, subjects of this thesis are service businessmen of tourist hote. in Kwangju area, and I investigate their way of thinking. I want this thesis shall be useful to efficient personnel management. The result of study is as follows. 1. A motive of employment and loss of employment It is found that hotel employees in Kwangju area decided employment not by their own will arbitrarily, but by other's will or meaninglessly. And it is exposed that the longer hotel employees are continuous their service, the more they leave their job. It is exposed that the reason of lose of unemployment is "for work at good hotol" and "by scout negotiation". 2. Occupational consciousness Respondents responded that tourist hotels had low social status and dark future, 67.9% of respondent responded that they wanted to continue their serve for 1-3 years. On the other side, 68.6% of respondent, including respondent who made answer of "be usual", responded affirmatively to the question about self-conceit as hotelmen. Ultimately. it is exposed that they have self-conceit as hotelmen, but they didn't content with hotel as their job. 3. Wages and working-environment Hotel employees in Kwangju area feel that their wages are guite dissatisfied with a remuneration for their work, but they have weak antipathy in comparison with wages level of other job. It is responded that they were content with working quantity and working-environment for the most part, but they were dissatisfied with welfare. 4. Service training and a labor union Accoding to investigation of questionaire, hotel employees are very interested in the necessity of service training. As many as 82.3% of respondent responded that service training was necessary. 82.6% of respondent responded that a labor union should be established. And it is responded that the necessity of a labor union was protection of rights and interests, improvement of working environment and welfare" and "for the substantial development of hotel" in the order named. 5. Policy of personnel management and human relations Hotel employees responded that the management was indifferent to raising the morale and did injustice to promotion and personnel changes. On the other hand, they made affirmative response, some extent, to the question asking response against employees' suggestion. And they made a quite affirmative response in the answer to the question about humans relations and teamwork with other employees or higher officer. They responded "improvement of welfare", "raising wages", "improvement of working environment" and "homely atmosphere" in the order named, to the question asking what they wanted most the hotel manager did. Generally, the result of actual investigation against way of thinking of service business employees in Kwangju area are found extraordinarily negative. The cause of these results is attributed to both employers and employees. But it looks like employers made more mistakes than employees did. Now times are changing. I think if employers disregard employees as usual, the growth of hotel industry shall be difficult to expect. So I think, hotel managers in Kwangju area should accept the result of this investigation, grow and take good care of man of ability even yet and consider a counterplan to use them. And I think employees should have management, increase trust with employers and endeavor to improve themselves reliably.

Leuconstoc mesenteroides와 Lactobacillus bulgaricus를 이용한 고점도의 발효유 제조에 관한 조건을 검토하였다. 발효유 제조의 최적 조건은 Skim milk 10%, yeast extract 0.2%, sucrose 10% 및 pH 6.8이였으며 배양온도는 30℃가 가장 좋았다. 접종비율에 의한 점도는 Leuconostoc mesenteroides와 Lactobacillus bulgaricus의 접종비가 1 : 1일 때 가장 높은 점도를 보였다. 수소이온농도는 혼합배양이 각각의 단독배양에 비하여 낮게 나타났으며 배양 12시간부터 높은 산도를 유지하였다. 24시간 배양한 혼합발효유의 총생균수는 8.7×10^9으로 단독배양의 경우보다 높게 나타났으며 이때의 점도는 2750 cps이었다. The conditions for the production of viscosity fermented milk by mixed culture method using Leuconostoc mesenteroides and Lactobacillus bulgaricus has been studied. The media composition and culture condition for optimum production of viscosity fermented milk were as follows: 10% f skim milk, 0.2% of yeast extract, 10% of sucrose, pH 6.8 and 30℃. Highest viscosity of culture broth was obtained with the same inoculation ratio of each microorganism. The final pH or mixed culture fermentation broth was ower than that of single culture broth of each microorganism. The total number of lactic acid bacteria and viscosity in final mixed culture broth after 24 hours of inoculation was 8.7×10^9 cells/m/ and 2750 cps. respectively.

Conditions for processing dried condiments with bloody clam were investigated. The enzymatic hydrolysis for 1 hour was more profitable than hydrothermal extraction to develop flavoring matters from bloody clam. As a result of omission tests, nucleotides were predominated in the taste compounds of bloody clam hydrolysates rather than free amino acids, and the contribution of nucleotides and free amino acids to the taste of bloody clam hydrolysates was remarkable. The major flavoring components of bloody clam hydrolysates were free amino acids and oligopeptides below 500 dalton. When bloody clam hydrolysates were separated with membrane(molecular weight cutoff 500 dalton) for recovering flavor, recovering yields of amino type nitrogen were 92.4%. Proximate compositions of dried condiments prepared with protease hydrolyzed bloody clam were moisture content 3.6%, total nitrogen were 71.2% amino nitrogen were 47.8%. And drying yield, solubility and absorption rates at Aw 0.88 were 21.4%. 86.3% and 6.6%, respectively.

Recently technology resulted in highly efficient and multiple-functional electric appliances considering environmental problems. One of the environmental problems is noise of a product in respect to its function. A vacuum cleaner is an essential electric appliance in our daily lives. However, severe noise resulted from high motor speed for improving the function of the appliance is a nuisance for the user. This noise is caused by vibration from various parts of the appliance and fluid noise during a series of intake and exhaust processes while rotating the impeller connected to the axle at a high speed of the fan motor inside the vacuum cleaner rotating around 30,000-35,000rpm. Despite the fact that many researchers conducted studies on reducing the noise level of the fan motor in a vacuum cleaner, only few studies have been conducted considering both the theoretical and experimental aspects using fluid analysis by measuring vibration and noise. Moreover, there has not been a study that accurately compared major noise data obtained considering both of the aspects. In this study, both aspects were considered by considering the following experimental and theoretical methods to verify the major causes of noise from the fan motor in a vacuum cleaner.

Diagnosis or measurements using Infrared thermo-image hasn't been available. A quick diagnosis and thermal analysis can be possible when that kind of system is introduced to the investigation of each part. In this study, Infrared Camera, Thermo-vision 900 was used in order to investigate. Infrared Camera usually detects only Infrared wave from the light in order to illustrate the temperature distribution. Infrared diagnosis system can be applied to various field. Also, it is more effective to analyze temperature distribution on the machining center main-axis process.
