  • The species diversity of Orchidaceae is believed to be extremely high in Myanmar. Like in other plant groups, little basic inventory work has been done thus far. During floristic surveys conducted in Popa Mountain Park (Mandalay Region), Natma Taung National Park (Chin State), and in the Ywangan area (southwestern Shan State), we encountered two interesting orchid species which were determined to be new generic records in the flora of Myanmar. Thuniopsis cleistogama was previously considered endemic to Yunnan Province (China) and was only known from the type locality. However, here the species is newly reported from two localities in central and western Myanmar. Disperis neilgherrensis is known from several widely scattered localities in tropical and subtropical Asia. This tiny orchid species was discovered in the Ywangan area in the southwestern area of the Shan State of Myanmar. These two species will be valuable additions to the updated checklist of the orchids of Myanmar.

  • To efficiently use frequency resources, the next 6th generation mobile communication technology must solve the problem of out-of-band emission (OoBE) of cyclic prefix (CP) orthogonal frequency division multiplexing (OFDM), which is not solved in 5th generation technology. This study describes a new zero insertion technique to replace an existing filtering scheme to solve this internal problem in OFDM signals. In the development of the proposed scheme, a precoder with a two-dimensional structure is first designed by generating a two-dimensional mapper and using the specialty of each matrix. A spectral shaping technique based on zero insertion instead of a long filter is proposed, so it can be applied not only to long OFDM symbols, but also very short ones. The proposed method shows that the transmitted signal is completely blocked at the bandwidth boundaries of signals according to the current standards, and it is confirmed that the proposed scheme is ideal with respect to bit error rate (BER) performance because its BER is the same as that of CP-OFDM. In addition, the proposed scheme can transformed into a real time structure through vectorizing process with minimal complexity.

  • 이 논문은 근대 민족국가 형성과 민족 공용어의 창출의 상관성을 염두에 두고 식민지기 버마에서 버마어가 어떠한 정치적, 사회적 환경 하에서 어떻게 공용어의 지위를 획득해나갔는지에 대해 주로 버마어 산문의 대중화라는 각도에서 분석한 것이다. 베네딕트 앤더슨의 연구가 시사하는 것처럼 근대적 인쇄매체의 출현과 더불어 근대 버마어의 등장 및 대중화는 버마의 근대적 민족 형성에 큰 영향을 미쳤다. 제1차 영국-버마 전쟁 종결 후, 정치, 사회, 경제적 상황 변화와 함께 인쇄산업의 발달과 더불어 버마어는 대중매체에서 공용어로서의 지위를 획득해갔다. 식민시기에 버마 내 여러 지역에 어학원이 설립되었고 버마인이 어학교육 담당자로 고용되었다. 1930년대 초반에 근대 버마어 산문이 많은 저자들에 의해 집필되었으며, 1930년대 후반에 들어서서 독자들 사이에서 널리 읽히는 호황을 누렸다. 일본군 점령 후에는 일본군 당국의 허가 하에 버마어는 제2차 세계대전 중에 공식적 언어로서 인정되었다. 이러한 바탕 위에 근대 버마어는 1947년 헌법에 버마의 공식 언어로 명기되었다. 이러한 과정에 대한 분석을 통해 이 논문에서는 버마어가 식민지기에 표준어로서의 지위를 획득하고 그 버마어로 작성된 근대 버마어 산문의 사용이 버마의 민족 형성과정에서 결정적인 역할을 하였다는 점을 부각시켰다.

  • In Myanmar studies, despite research on the categorization of ethnic nationalities are fairly much, research on the categorization of Myanmar people (ethnic Myanmar) is rarely exposed. People settled down in Central Myanmar had been categorized by regionalism into two groups as Anyatha (Upper Lander) and Auktha (Lower lander). It can be determined that the regionalism of Myanmar people existed and still exists. Previous scholarship in the colonial history of Myanmar has primarily referred to the documents recorded by the colonial officers and historical texts composed by the British authorities and scholars. The Catalogue of the Hluttaw Records is one of the rarest documents recorded in the Myanmar language on the affairs in the borderline drawn by the British after the Second Anglo-Myanmar War (1852-1853). Scrutinizing the Catalogue of the Hluttaw Records, it has been found that the text sheds light on the division of Central Myanmar into two regions in colonial Burma, later known as Lower Myanmar and Myanmar kingdom. These areas were known as Upper Myanmar between 1853 and 1885, and the categorization of the Myanmar king's subject, known as Anyatha (Upper Lander) and British colony citizen later known as Auktha (Lower Lander). This article traces back the relation of introducing the colonial boundary system and the division of Central Myanmar into two regions that allowed the emergence of regionalism among Myanmar people.

  • The most effective tutoring method is one-on-one, face-to-face in-person human tutoring. However, due to the limited availability of human tutors, computer-based alternatives have been developed. These software based alternatives are called Intelligent Tutoring Systems (ITS) which are used to tutor students in different domains. Although ITS performance is inferior to that of human teachers, the field is growing and has recently become very popular. User interfaces play key role in usability perspective of ITS. Even though ITS research has advanced, the majority of the work has concentrated on learning sciences while mostly disregarding user interfaces. Because of this, the present ITS includes effective learning modules but a less effective interface design. Usability is one approach to gauge a software's performance, while "ease of use" is one way to assess a software's quality. This paper measures the usability effectiveness of an ITS which is designed to teach Object-Oriented (OO) analysis and design concepts using Unified Modeling Language (UML). Computer Supported Usability Questionnaire (CSUQ) survey was conducted for usability evaluation of UML-ITS. According to participants' responses to the system's usability survey, all responses lie between 1 to 3 scale points which indicate that the participants were satisfied and comfortable with most of the system's interface features.

  • Objective : The researcher participated in the visiting treatment project organized by OO City in 2020 and showed the advantages of visiting Korean Medicine, so I would like to report it. Methods : A comprehensive Korean Medicine intervention method was performed for each symptom, and changes in basic physical strength were observed through vital signs, NRS, Single Leg Stance (SLS), and Chair Stand Test (CST) tests. Results : It can be seen that the NRS level, a pain scale for chronic pain, generally decreased at the last treatment compared to the beginning of treatment. Satisfaction with Project Information (PI) was relatively low at 3.20±1.30, but Ease of Participation (EoP), Intention to Participate Again (IPA), Expansion of Project (ExP), and Overall Satisfaction (OS) were high at 5.00±0.00. Conclusions : Summarizing the advantages of visiting Korean Medicine is that the treatment satisfaction for chronic pain is high, the patient's satisfaction is high, the treatment tool is easy to carry, and various visiting treatment services can be implemented.

  • In this study, we focus on the recycling of cardboard waste and sugarcane bagasse (SCB) for the preparation of carboxymethyl cellulose (CMC) and its conversion into a biodegradable film. Sodium alginate (SA) was added to form a biodegradable composite film. SA was used to increase film permeability. Glycerol, which is a plasticizer, was used to increase the tensile strength (TS) and film expansion. To characterize the CMC, X-ray diffraction, Fourier transform infrared spectroscopy, and scanning electron microscopy were used. The addition of olive oil to the CMC-SA matrix highlighted its antimicrobial property against Escherichia coli (E. coli) and Staphylococcus aureus (S. aureus). A slight decrease in tensile strength was observed with the addition of olive oil (OO), which improved the functional properties of the control films as well as lowered moisture content and water solubility. But considering all other factors, the composite films obtained from sugarcane bagasse and cardboard waste incorporated with olive oil are suitable for applications in the field of food packaging.

  • Past theories on construction price formation have been shown to be inadequate in terms of their ability to represent real-life industry practice and price formation predictability. In this paper, we develop a theoretical framework on construction price formation that integrates four theories within the domains of marketing, learning, resource management and economics. These are: (i) marketing pricing theory; (ii) experiential and organisational learning theory; (iii) resourced based theory and (iv) microeconomic theory. Utilising pricing theory from marketing, a foundation is able to be created for the procedure of construction price formation, namely: (i) identifying the objectives; (ii) assessing the tendering environment; and (iii) formation of the price. However, understanding contractors' decision making process in tender pricing as such can be attributed to theories of experiential learning and consequently organisational learning. It is argued that contractors do learn from past experience and history and are able to adapt to different market conditions. In formation of the price, neoclassical microeconomics is able to provide additional insight in terms of the supply and demand model and consideration of the market conditions. Interrelated with the microeconomic concept of scarcity, we appreciate that contractors do have limited resources that affect their tender pricing decisions and resource based theory is used to substantiate this. Integrating the various theories as a unity allows the broader reality to be visualised and add to our theoretical understanding of construction price formation.

  • The purpose of this study was to identify the level of HIV/AIDS related knowledge and attitudes of Korean childbering women. The subject were 1152 Korean women who were living in the Seoul area and whose age was between 17-50 years. Data was collected by self reporting with a questionnaire of 57 items developed by the researcher. The reliability of the instrument for the HIV/AIDS related knowledge and attitudes were Cronbach's alpha. .6954 and .7987 respectively. The results were as follows: The mean age of the subjects was 26 years and 46.8% of them were married. The mean score for HIV/AIDS related knowledge was 14.7 out of a possible maximum score of 22. The correct answer rate for HIV/AIDS related knowledge was between 87.0-94.1% for the risk factors. and 36.4-54.8% for the transmission mode. Even though 87% of the subjects knew that homosexuals are risk group for HIV/AIDS. only half(55.8%) of the subjects answered that anal sex is the transmission mode. And only 57% of the subjects knew that HIV/AIDS transmission is possible through heterosexual contact. Their agreement level for attitudes was in order of communal coping (95%). pregnant women protection (94%). Problem appraisal (82%). patients isolation(68%). and disclosure of infection(67%). It was shown that the group who had a pregnancy (t=2.07, p=.039), used contraceptives (t=2.57, p=.OO1). and the group of college level graduates(t=3.61, p=.000) had a higher level of HIV/AIDS related knowledge. The agreement level of pregnant women protection. patient isolation. and problem appraisal were higher in the group of having had a pregnancy, having used contraceptives. and the group over 30 years of age. It was concluded that Korean childbearing women were quite knowledgeable about the risk factors but confused about the transmission mode. especially heterosexual contact. and they showed responsive attitudes to the HIV/AIDS issues considering the 339 infected cases in Korea. They preferred isolation of patients and communal coping as behavioral attitudes. Therefore it can be suggested that a HIV/AIDS prevention program should be focused on transmission mode.

  • Recently the cyber home learning system is executed throughout the country as a part of educational policies to reduce expenditure on private education and to promote educational welfare for alienated classes. Thus, in order to examine the effectiveness of the cyber home learning system, we conducted an online questionnaire survey with elementary and secondary students, cyber teachers under the OO Office of Education. According to the results, overall satisfaction with the cyber home learning system and its effectiveness were found high. In addition, what were required for more effective the cyber home learning system were expanding the execution of unit school learning, strengthening teacher training, increasing incentives for cyber teachers, intensifying campaigns for the cyber home learning system, providing various types of information and contents of education, and activating learning activities such as community, message and chatting. This study is expected to be a steppingstone to the settlement of more effective the cyber home learning system.
