With the increase in smartphone ownership and Internet usage using smartphones, the information environment is shifting from the existing PC to the smart mobile. The current undergraduate students are called Generation Z who prefer smartphones to PCs and video contents to texts. This study attempted to understand their usage behaviors of electronic resources in an academic library in a smart mobile environment. This study conducted a usage statistics analysis with 61,433 usage records of e-books, audiobooks, and e-learning contents and 1,595 records of users in the A academic library during 3 years from 2016 to 2018. The scope of the data includes the date of use, the subject, the year of publication, the channel of use, and each user's gender, affiliation, status, admission date, and graduation date. This study investigated not only the general characteristics of electronic resource use, but also the usage behaviors according to the user's demographic characteristics. Based on the findings, this study suggested practical service plans that are applicable in the near future and reflect changing circumstances.

모발(human hair)은 양모섬유와 마찬가지로 시스틴을 많이 함유하고 있는 섬유상 케라틴 단백질로써, 두부(頭部)를 보호할 뿐만아니라 신체에 필요하지 않는 중금속을 체외로 방출하는 기능을 지닌 신체의 일부분이다. 또한 모발은 미(美)와 관련하여 가장 관심을 가지는 부분이며, 다양한 방법으로 모발에 변화를 주어 신분을 표시하거나 자신의 미적 표현을 하고 있다. 퍼머넌트 웨이브는 모발에 형태학적 변화를 주는 유효한 수단이며, 염색과 탈색 등은 색상 변화를 주는 중요한 수단이다. 본 연구 에서는 모발을 산성염료로 염색할 때 염색성을 향상시키기 위하여 염색보조제로써 벤질알콜 등을 첨가하여 염색할 때 염색된 모발의 염착량, 보습성, 단백질 유출성, 주사전자 현미경 관찰을 측정하여 다음과 같은 결과를 얻었다. 1) 염색시간이 길어지고, 염색온도가 높아질수록 모발에의 염착량은 증가하며, 특히 벤질 알콜을 첨가하여 염색하는 경우에는 빠른 시간내에 염착평형에 도달하고 비교적 낮은 염색온도에서도 높은 염착량을 나타내었다. 2) 이와같은 용매 첨가의 효과는 염액에 계면활성제와 함께 첨가하여 염색하면 나타나지 않았다. 3) 염색시간이 길어질수록 모발의 보습성은 열악해지지만, 벤질 알콜을 첨가하여 염색하는 경우에는 오히려 보습성이 증가하였다. 또한 염색시간이 길어지면 모발의 단백질 유출성은 증가하지만, 벤질 알콜을 첨가하여 염색하는 경우에는 오히려 단백질 유출성이 감소하였다. 이와같은 결과는 벤질 알콜을 첨가하여 염색하는 경우에 모발의 손상이 적다는 것을 의미한다. 4) 모발의 손상정도에 대한 주사전자현미경의 측정결과는 벤질 알콜의 첨가여부에 따라 큰 차이를 보이지 않았다.

This study examines the modern succession, transformation and significance of enjoyment methods of classical literature (art) with a focus on the characteristics of those methods that appeared when the performances of the traditional era began to be displayed on the stage of the theaters in modern Seoul. The clues to the reasons for this type of enjoyment can be found in newspapers, magazine articles, and advertisements from the early 20th century. The emergence of stage theaters at the beginning of the modern era caused a sweeping change in the performance environment, including the fact that it was possible for all kinds of people to enjoy art beyond the existing socioeconomic hierarchies or barriers of status, that the performers were given employment through the theater, and that the audience had the tendency of the general public of an unspecified number because the audience was able to see the performances only by paying the viewing fee. The way of enjoying traditional performances also changed based on these new adaptations: the performances were sequential, show-oriented, and re-contextualized as public performances. It is significant that in the traditional era, performers and audiences had been segregated according to their status and a strict hierarchy; now, such cultural norms were breaking down in favor of a kind of equality. In addition, it was possible for the audience to experience sensory enjoyment, and theater brought about a new kind of popular consumer enjoyment of an artistic product. Of course, though, it is possible to look back and find problems related to the contemporary context, but the traditional performances, which were the main performances for the lower class, took the first place on the modern theater stage, and as a result, no one can deny that it became possible to move forward in the first phase of an era of public performance.

Iron-making industries of the country, regardless of age has been the focus. This makes the iron production technology and production techniques that result in increased economic activity and because of the central charge. Therefore, the social development of ancient iron-making technology is based on phase-sensitive. Modern steel making up the monopoly of the country's target under the strict control of production, distribution was. It is essential to produce iron weapons was a threat is because you can keep the throne in the hands of the forces that can cause side effects when I went was to block. This study created a rail Cholbi(iron monument) and the regional distribution pattern of the production, construction background, looked on. Cholbi(iron monument) for the production and recording "the Annals of the Joseon Dynasty" often appear in history books and many academic interests, but was off target. Compared to a stone monument that was not generally as well as the Japanese colonial period and over the course of modernization destroyed, damaged a lot of cases the cause may be found in front. Cholbi(iron monument), except for the gravestones of the Joseon Dynasty monument erected in honor of virtue, as an example of content that dominated a packman business, founding of the school and confirmed that a few were built as a special purpose. Cholbi(iron monument) compared to the production technology or the cost of the monument's difficulty in financing follows. Therefore Cholbi(iron monument) the establishment of the Joseon Dynasty through the background of the economic situation and the local government can look. And iron technology began complaining about the object of history, economic conditions, with the change of season has been a change in people's consciousness tells you. Important data of ancient history as an epigraph that has been as important, the Middle Ages to modern times ranging from newly born to the time Cholbi(iron monument) in the development of the country's documentary subject to change should have been brought. Based on these discussions changes the identity of the hero monument and production inspector, review of production through the Joseon Dynasty period Cholbi (iron monument) contemplated the significance is reflected in production.

Recently, the important of a personal identification is increasing according to expansion using each on-line commercial transaction and personal ID-card. Although a personal ID-card embedded RFID(Radio Frequency Identification) tag is gradually increased, the way for a person's identification is deficiency. So we need automatic methods. Because RFID tag is vary small storage capacity of memory, it needs effective feature extraction method to store personal biometrics information. We need new recognition method to compare each feature. In this paper, we studied the face verification system using Hippocampal neuron modeling algorithm which can remodel the hippocampal neuron as a principle of a man's brain in engineering, then it can learn the feature vector of the face images very fast. and construct the optimized feature each image. The system is composed of two parts mainly. One is feature extraction using NMF(Non-negative Matrix Factorization) and LDA(Linear Discriminants Analysis) mixture algorithm and the other is hippocampal neuron modeling and recognition simulation experiments confirm the each recognition rate, that are face changes, pose changes and low-level quality image. The results of experiments, we can compare a feature extraction and learning method proposed in this paper of any other methods, and we can confirm that the proposed method is superior to the existing method.

Face recognition technique is very popular for a personal information security and user identification in recent years. However, the face recognition system is very hard to be implemented due to the difficulty where change in illumination, pose and facial expression. In this paper, we consider that an illumination change causing the variety of face appearance, virtual image data is generated and added to the D-LDA which was selected as the most suitable feature extractor. A less sensitive recognition system in illumination is represented in this paper. This way that consider nature of several illumination directions generate the virtual training image data that considered an illumination effect of the directions and the change of illumination density. As result of experiences, D-LDA has a less sensitive property in an illumination through ORL, Yale University and Pohang University face database.

This study was aimed to provide understanding on the eco-physiological response of barley tillers as affected by difference in seeding date. Yield and yield contribution rates of tillers were investigated with the data of field experiments in the former Wheat and Barley Research Institute of Suwon, Korea from September 1982 to July 1984. When barley was sowed 15 days earlier than or at the locally recommended sowing date (i.e. October 5), it produced more mainstem leaves than the that sowed 15 days later than the local recommendation. The effective tillers (i.e. ear-bearing tillers) were observed in concurrently occurring leaves up to 10/0 (abbreviation of the 10th mainstem leaf) from early and optimum sowed crops, while 9/0 from late sowed crops. Tillering followed the production rule of Gatayama(l952) which has the linear leaf appearance pattern. Early sowing produced more effective tillers, but the highest production of effective ears (i.e. ears heavier than 0.505g) was noticed in sowing at the recommended date. The tillers in the axil of first leaf in mainstem (abbreviated as 1) produced more effective ears than other mainstem tillers (i.e. primary tillers such as C, 2, 3 and 4). The tillers from the axil of first leaf, whether they were primary or secondary, always performed better in the production of effective tillers, grains per ear, grain weight, and grain yield per ear than those from the axil of coleoptile or prophyll. Other tillers from subsequent leaves were also inferior in production with the order of their appearance, thus making first leaf tillers as the best performer(e.g. 1 against C, 2, 3, 4 of primary tillers, 11 and 21 against 1P, 12, 13, 2P, 22 of secondary tillers). Even though the first leaf tiller from the first mainstem leaf(i.e. 11) emerged at a same time with the fourth mainstem leaf tiller(i.e. 4), it was always a better producer of ears and grains. The above observations of hierarchy among tillers were persistent irrespective of cropping conditions and treatments. Sowing at the recommended date produced more effective tillers and grains per ear than early or late sowing. In early and late sowings, more grains per effective ear were observed by early sowing, whereas more grains per ear were produced by late sowing. The order of performance in production of effective tillers and ears per plant was as follows: optimum > early > late sowings. In optimum sowing the mainstems were the highest in grain weight per ear, while the first leaf tillers were the ones in early sowing probably due to winter damage on mainstem ears. Yield contribution by the tillers was greater with the following order irrespective of sowing dates: mainstem, 1, 2, 3, C, 11, 12 and Cl. The contribution of CP, 2P, 21 and 31 varied with sowings.
