Compressive strength behaviour of low-strength hollow concrete block masonry prisms
Hopeful Syiemiong,Comingstarful Marthong 국제구조공학회 2021 Structural Engineering and Mechanics, An Int'l Jou Vol.80 No.6
The present study aims to understand the behaviour of low-strength masonry prisms constructed with locallyproduced low-strength hollow concrete blocks. Compression tests were conducted on masonry prisms constructed with three different mortar grades of cement-sand ratios of 1:3, 1:4.5 and 1:6 representing strong, moderately strong and weak mortar. Stress-strain curves were generated from the test results for the masonry prisms. The hollow concrete masonry units employed in this study are some of the weakest as compared to other masonry units employed by other researchers. The compressive strengths for masonry prisms with mortar grades 1:3, 1:4.5 and 1:6 are 2.21 MPa, 2.19 MPa and 2.25 MPa respectively. The results indicate that the masonry compressive strength of such low-strength hollow concrete block masonry prisms is not influenced by the mortar strength. Simple relationships to estimate the modulus of elasticity and compressive strength of masonry prisms is also proposed.
A Cocktail of Vices: International Ethics and the Jeju Incident
Hope Elizabeth May 건국대학교 인문학연구원 2018 통일인문학 Vol.4 No.2
This paper presents an analysis of the Jeju 4.3 incident through a framework of virtue, vice and international ethics. By utilizing primary source documents such as the United States’ Military Intelligence reports (the G-2 Weekly Summaries and Periodic Reports), the incident is described as arising from a “cocktail of vices” – including not only cognitive errors, but also affective vices of character such as factionalism and the inability to compromise. Seen in this way, the Jeju incident offers a lesson about international ethics of which we should be mindful as we move towards the peaceful unification of the two Koreas.

Successful manufacturing operations in the U.S. will enable multinational enterprisesfrom developing econo- mies (MEDECs) to gain proximity and improved responsiveness to their biggest single target market as well as facilitate their evolution into global corporations. However, international expansion often leads to failure. This study examines the attributes that distinguishes successful MEDECs engaged in U.S. manufacturing from less suc- cessful ones. A discriminant analysis classification model reveals that larger firms and those producing patented products have higher levels ofperformance. Further, minorityforeign-ownedfirms tended to outperformfirms that were majority foreign -owned.
Moral Development and the March First Movement
Hope Elizabeth May 건국대학교 인문학연구원 2019 통일인문학 Vol.5 No.1
This paper offers a discussion of the March First Movement of 1919 (MFM) through the lens of moral development. Central to the discussion is the moral development of the most well-known personality associated with the MFM, Yu Kwan-sun (1902-1920). After discussing Yu’s own moral development, I connect this discussion to another important but less well-known figure associated with the MFM, Lee Sŭnghun (1864-1930). As a chief organizer of the MFM, Lee Sŭnghun made it possible for Yu Kwan-sun to both display and further develop her virtues and moral energies during the MFM. A discussion of Lee Sŭnghun also enables us to appreciate the thread of moral energy that was spinning prior the MFM, and which blossomed into the MFM in large part due to his efforts. I close by briefly discussing another participant in the MFM, Louise Yim (Im Yŏngsin) (1899-1977). Like Yu Kwan-sun, Yim was imprisoned and tortured for her participation in the MFM. Unlike Yu, however, Yim survived and dedicated her adult life to the independence of her country and the education of its citizens. A deeper consideration of the individuals involved in the MFM can connect us in the present to their virtues and moral energies. To know these individuals is to be inspired and moved by them. Thus the stories of the individual participants in the MFM remain an important resource for international ethics.
Recognition and Responsibility: The Moral Relevance of Pre-UN history to the Jeju Tragedy
Hope Elizabeth May 세계환경사회거버넌스학회 2016 World Environment and Island Studies Vol.6 No.4
I highlight morally relevant history - of Korea, of The United States and of The early years of the United Nations (UN), which tends to be ignored in the discussion of the Jeju tragedy - a seven year period of brutality on Jeju Island, South Korea, that lasted from March 1, 1947 to September 21, 1954. While discussions of these events acknowledge the responsibility of the United States Army Military Government in Korea (USAMGIK), they overlook the connection of the tragedy to Korea’s earlier history - such as its Independence Movement in the early 1900s. Also overlooked is the way in which the US created machinery in the early years of the UN that was the sine qua non of the controversial UN monitored elections which were the flashpoint of the incident. This Pre-UN and early UN history is poignantly connected to the Jeju tragedy, as we will see, and is crucial for understanding its full significance. Sadly, however, this history is dimly understood. For the sake of understanding the full scope of moral responsibility for the Jeju tragedy, and for reconnecting to the values and virtues important for all people, this overlooked history must be brought to light.

The March 1st Movement and the Red Thread of International Peace History
Hope Elizabeth May 한국학술연구원 2019 Korea Observer Vol.50 No.2
This paper offers a narrative that transcends the received view of the March 1, 1919 Movement as a nationalist, anti-Japanese Movement for Korean Independence. Moving beyond the description of the Movement as one for independence and self-determination, I discuss the March 1st Movement within the deeper context of international peace history. When we transcend the traditional narrative and position the March 1st Movement and its participants within broader geographic, social and historical contexts, the cosmopolitan and humanitarian dimensions of the Movement are illuminated. Understood as a complex landscape of stories that illustrate an awakened conscience, cosmopolitan affection and the politics of hope, the March 1st Movement shines as an important moment in the red thread of international peace history.
Effect of moisture on the compressive strength of low-strength hollow concrete blocks
Hopeful Syiemiong,Comingstarful Marthong 사단법인 한국계산역학회 2019 Computers and Concrete, An International Journal Vol.23 No.4
In order to study the effect of moisture on the compressive strength of low-strength hollow concrete blocks, an experimental study was carried out on 96 samples of locally manufactured hollow concrete blocks collected from three different locations. Uniaxial compression tests were conducted on dry specimens and three types of saturated specimens with moisture contents of 30%, 50% and 80% respectively. The range of moisture content adopted covered the range within which the concrete block samples are saturated in the dry and monsoon seasons. The compressive strength of low-strength hollow concrete blocks decreases with increase in moisture content and the relationship between compressive strength of hollow concrete blocks and their moisture content can be considered to be linear. However, the strength degradation of 30% moist concrete blocks with respect to dry blocks is relatively low and can be considered to be comparable to dry concrete blocks. A formula indicating the relationship between the moisture content and compressive strength of low-strength hollow concrete blocks is also proposed.
