피처폰에서 스마트폰으로의 모바일 혁명과 All IP기반의 Network는 IT 생태계 변화에 있어 통신산업을 비롯하여 모든 산업분야의 변화를 촉구해 왔다. 하룻동안 구글의 Play store에 등록되는 앱의 수와 개통되는 안드로이드 기그들은 수십 만개에 달하고 스마트폰은 이제 단순한 사람과 사람과의 통신의 수단이 아닌 나와 연결된 모든 사물과 통신하기 위한 수단이 되고 있다. 이러한 폭발적인 모바일 성장과 함께 통신회사들도 자신들의 강점인 유무선 통합을 기반으로 사업을 확대하거나 신성장 동력을 찾으려는 많은 시도를 해왔다. LG 유플러스도 이러한 변화의 소용돌이를 극복하기 위해 과거 LG텔레콤, LG데이콤, LG파워콤의 3사 합병의 조직 변화를 시도했고, 유무선 네트워크 기반의 인프라를 중심으로 다양한 서비스 플랫폼을 구축하고 있으며, 이를 기반으로 다양한 서비스의 기획에서 상용화까지 경쟁력 있는 서비스를 쉽고 빠르게 제공할 수 있도록 하고 있다. 또한 플랫폼과 서비스, 플랫폼과 플랫폼간의 유기적인 연동을 통해 보다 차별화된 융합서비스와 개방형 API으로 누구나 쉽게 자사의 플랫폼과 서비스 기능을 사용할 수 있도록 생태계 조성에 힘을 쓰고 있다. 본 고에서는 LG U+의 플랫폼과 서비스 중 M2M분야에 대해 알아보고, M2M/IoT에서의 다양한 활동을 통해 LG U+가 바라보는 M2M/IoT의 미래를 조명해 보고자 한다.

Ultraviolet rays (UV) cause photoaging by inducing skin photodamages such as erythema and sunburn. Silymarin is a mixture of antioxidant polyphenols extracted from Silybum marianum fruit (S. m), which is known as milk thistle. It is known to protect skin tissues from UV treatment and antioxidant effects. In this study, we aimed to identify the photoprotective effects of S. m extract, which has silymarin in the epidermis layer of the skin. We found that the extract can function as a UV filter, so it can reduce DNA damage by UV treatment. Especially, we found that, in the stratum corneum, the extract can suppress the protein carbonylarion and DNA damages caused by suberythemal dose of UV treatment which does not induce erythema in the skin. UV treatment also increased protein carbonylation levels in the stratum corneum by oxidation, but it was prevented by applying the extract. The extract can absorb UV with minimal phototoxicity. Together, our study suggests that S. m extract can be used as a photo-protective ingredient to avoid photoaging of the skin.

lgM-like immunoglobulin was purified from the immune serum of M albus which immunized with bovine Serum albumin(BSA) as an antigen(Ag) and characterized. The Ag-specific antibody activity of the immune serum was increased after the immunization. The purified lgM-like immunoglobulin had a tetrameric structure which had a molecular weight of 800 kD and the monomer of IgM-like Ig had a mass of 199 kD which was composed of two heavy chains (Mol. wt. 70 kD) and iwo light chains (Mol. wt. 29.5 kD). The IgM-like Ig showed hemaggluti nating activity to mammalian RBC slightly.

The active layer thickness and curing condition dependent performance of an organic thin film transistor (OTFT) with inkjetted organic semiconductor (OSC) layer is studied The best performance of the OTFT was found when the thickness of ose was ~120 nm cured at $60^{\circ}C$. The performance enhancement of the OTFT with inkjetted OSC layer was discussed by comparing the OTFT with spin-coated ose layer.

M&A is an important strategic decision made to ensure the competitiveness of companies and cases of M&A have been increasing in recent years. But the success of an M&A is not assured. In order to succeed, there should first be a well managed strategic leadership by the CEO and an integration strategy. Companies need also to overcome the resistance to change among members. A successful example of an M&A is that of LG Chem and Hyundai Petrochemical. By using this M&A as a case study, the influence of the CEO's Strategic Leadership, and the Integration Strategy on Resistance, Acceptance and Performance were assessed. For this study, research was conducted on CEO Strategic Leadership and Integration Strategy before members of LG Chem (DAESAN PLANT) were interviewed on the M&A's implementation by LG Chem's HR staff, management and members. The results show that CEO strategic leadership and the integration strategy are major change drivers and that they are important to the early stabilization of M&A companies. Finally, suggestions are made as to how such success may be replicated for other companies undergoing M&A in the future.

A novel microorganism, designated as LG12, was isolated from soil based on its ability to use acrylic acid as the sole carbon source. An electron microscopic analysis of its morphological characteristics and phylogenetic classification by 16S rRNA homology showed that the LG12 strain belongs to Rhodococcus erythropolis. R. erythropolis LG12 was able to metabolize a high concentration of acrylic acid (up to 40 g/l). In addition, R. erythropolis LG12 exhibited the highest acrylic acid-degrading activity among the tested microorganisms, including R. rhodochrous, R. equi, R. rubber, Candida rugosa, and Bacillus cereus. The effect of the culture conditions of R. erythropo/is LG12 on the production of 3-hydroxypropionic acid (3HP) from acrylic acid was also examined. To enhance the production of 3HP, acrylic acid-assimilating activity was induced by adding 1 mM acrylic acid to the culture medium when the cell density reached an $OD_{600}$ of 5. Further cultivation of R. erythropo/is LG 12 with 40 g/l of acrylic acid resulted in the production of 17.5 g/l of 3HP with a molar conversion yield of 44% and productivity of 0.22 g/l/h at $30^{\circ}C$ after 72 h.

When boron ions are doped into the poly-Si films, the hydrogen ions doped with boron ions compensate the defect sites and suppress to produce damage density. These samples can be easily activated by hydrogen doping at high acceleration voltage($V_{acc}$).

The visual perception tests were conducted to determine limits of luminance of a LCD TV from a viewpoint of glare. The results showed that people, who watch TV in their living room, perceive glare above $410\;cd/m^2$ at full window and $590\;cd/m^2$ at 1/25 window.
