Ewha Womans University is a private women's university in central Seoul, South Korea founded in 1886 by the American Methodist Episcopal missionary Mary F. Scranton. It is currently the world's largest female educational institute and is one of the most prestigious universities in South Korea.While the lack of an apostrophe in "Womans University" is unconventional, the use of "Woman's" rather than "Women's" was normal in the past.Τhe use of "Womans" carries special meaning. The early founders of the college thought that every woman in this community is worth being respected; to promote this idea, they chose the word "woman" to avoid lumping students together under the word "women."

This prospective randomized study compared the clinical outcomes of patients who underwent partial-thickness articular-sided rotator cuff repairs by 2 surgical techniques. Forty-eight patients with a symptomatic partial-thickness articular-sided rotator cuff tear exceeding 50% of the tendon thickness were randomly assigned to 2 groups at the time of operation. Of the patients, 24 received arthroscopic rotator cuff repair with a transtendon technique (group I) and 24 received arthroscopic rotator cuff repairs after tear completion (group II). Pain intensity and patient satisfaction were assessed by visual analog scales, and functional outcomes were evaluated by use of American Shoulder and Elbow Surgeons and Constant shoulder scores. Tendon integrity was evaluated by magnetic resonance imaging at 6 months after surgery. Clinical outcomes were significantly improved after repair in both groups at a mean of 31 months' follow-up. In each group 22 patients (92%) were satisfied with surgery. However, shoulder function and range of shoulder motion recovered faster in group II during the recovery period (American Shoulder and Elbow Surgeons score, 54.9 ± 3.7 in group I v 64.6 ± 3.2 in group II; P =.037) (Constant score, 57.9 ± 2.9 in group I v 70.8 ± 3.3 in group II; P =.019). Furthermore, patients in group I had significantly more pain (5.9 ± 0.4) than patients in group II (2.8 ± 0.5) (P =.001) until 3 months after surgery. Postoperative adhesive capsulitis developed in 3 patients in group I and in 2 patients in group II. According to postoperative 6-month magnetic resonance imaging assessments, all patients in group I achieved complete integrity whereas a retear developed in 2 patients in group II. Arthroscopic repair of partial-thickness articular-sided rotator cuff tears exceeding 50% of the tendon thickness provided satisfactory functional improvements and pain relief regardless of the repair technique. Although repair after conversion to a full-thickness tear showed less postoperative morbidity, tendon integrity is of primary concern after repair. On the other hand, the transtendon repair technique resulted in complete tendon integrity but slower functional recovery. Level II, prospective comparative study.

Knowledge about the importance of fluoride ions in biological and medical processes has grown in recent years. It is now known that this anion plays a role in dental health and has potential use for the treatment of osteoporosis. Fluoride is easily absorbed by the body but is excreted slowly. Fluoride also plays an important role in a number of military applications. For example, the refinement of uranium in nuclear weapons manufacturing utilizes fluoride. GB, more commonly known as sarin (isopropyl methylphosphonofluoridate), is a nerve agent employed by the Aum Shinrikyu cult in terrorist attacks in Tokyo in 1995. Over the past two decades, a large number of optical sensors have been developed for detecting fluoride. For the most part, the methods employed in these sensors rely on strong interactions taking place between Lewis-acidic boron and fluoride, as well as hydrogen bonding and other types of interactions involving fluoride as a participant or a disrupter. In addition, reaction-based chemodosimeters have been devised for the selective detection of fluorides.

The development of cyclometalated Ir(III) complexes has enabled important breakthroughs in electroluminescence because such complexes permit the efficient population of triplet excited states that give rise to luminescent transitions. The triplet states of Ir(III) complexes are advantageous over those of other transition metal complexes in that their electronic transitions and charge-transfer characteristics are tunable over wide ranges. These favorable properties suggest that Ir(III) complexes have significant potential in a variety of photofunctions other than electroluminescence. In this critical review, we describe recent photonic applications of novel Ir(III) complexes. Ir(III) complexes have been shown to affect the exciton statistics in the active layers of organic photovoltaic cells, thereby improving the photon-to-current conversion efficiencies. Nonlinear optical applications that take advantage of the strong charge-transfer properties of triplet transitions are also discussed. The tunability of the electrochemical potentials facilitates the development of efficient photocatalysis in the context of water photolysis or organic syntheses. The photoredox reactivities of Ir(III) complexes have been employed in studies of charge migration along DNA chains. The photoinduced cytotoxicity of Ir(III) complexes on live cells suggests that the complexes may be useful in photodynamic therapy. Potential biological applications of the complexes include phosphorescence labeling and sensing. Intriguing platforms based on cyclometalated Ir(III) complexes potentially provide novel protein tagging and ratiometric detection. We envision that future research into the photofunctionality of Ir(iii) complexes will provide important breakthroughs in a variety of photonic applications. © 2012 The Royal Society of Chemistry.

Light up tomorrow: A photochromic material with excellent fatigue resistance, high thermal stability, and quantitative photoswitching can be used as a linear photoswitching material to replace nonlinear optical materials for encoding optical signals. Therefore, information in one light ray can be directly transmitted to another light ray without converting back to the electronic format. © 2014 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
